Acoustic sample testing approach – calculation procedure - KBCN1675
The methodology sets out a sample testing approach which can be applied to group rooms into those of similar room type or performance requirement category or construction type.
Where rooms are grouped to the same use and construction for instance, only 1 in 4 pairs of adjacent rooms would need to be tested, and the results would be representative of all similar rooms e.g. where there are 12 pairs of similar offices and 3 are tested and are compliant, all 12 would be deemed compliant (or 100%).
Therefore, it is not a requirement to test 80% of the rooms to be 80% compliant for those projects where a sampling approach can be applied.
Aggregating utility bill data - KBCN1422
All energy consumption data related to the BREEAM In-Use Part 2 Energy Calculator must be actual metered data collected in relation to the assessed area. However, where billing dates from different meters within the assessed area cannot be aligned, the following acceptable solution common in the market place can be used.
Where an asset has a multiple utility meters that bill on different days it is possible to use a pro-rata method to align the billing periods provided that the actual meter readings are undertaken every month, and that the calculations do not extrapolate data over a period longer than one month.
Alarm systems – Intent of Criterion 2 - KBCN1707
The intent of Criterion 2 is as follows:
A documented plan is in place to ensure that when the alarm is triggered, whether due to a fire or security incident, a system fault or a false alarm, building staff and occupants understand what actions to take. This must include any necessary communication with ARC staff, emergency services and other building users.
This clarification will be incorporated in the next update of the technical standard.
Alignment between BREEAM and the Fitwel certification system - KBCN0737
BRE, as an independent and impartial research-based organization, is working with the Center for Active Design (CfAD) and International WELL Building Institute (IWBI) to promote and improve health and well-being in the built environment. The aim of both these agreements is to support our clients who want to pursue either Fitwel or WELL alongside the BREEAM standard.
To simplify the process for project teams pursuing both assessment methods, BRE has worked together with the respective organizations to compare performance requirements, identify specific documented credits and evidence that will be recognized by both organizations to streamline the process of achieving dual certification. This work demonstrates the significant synergies between the various methods and the efficiencies that exist between their respective assessment and certification processes. Because of BRE’s unique position as an impartial organization, it is possible to form these important collaborations with like-minded organizations to work together to harmonize approaches to health and wellbeing in the built environment across their standards, research programs and services.

Alternative methods for ensuring the re-use or recycling of materials - KBCN1150
In a scenario where management processes result in the recycling or re-use of a waste stream, this can be considered as one additional compliant waste stream within the question. For example, sites where a take-back scheme is utilised with installers/manufacturers for a particular waste stream, and the manufacturer re-uses or recycles this off-site.
In order for this to be compliant the following must have been met:
- The Assessor must clearly outline the waste stream which is being recycled/re-used
- The Assessor must clearly outline the process which occurs, including: (a) How the waste leaves the site, and (b) What happens to the waste after it leaves the site
- If the waste is transferred to another party (such as a supplier in a take-back scheme), there needs to be evidence of a current valid agreement/contract in place outlining that this service will be provided for at least 12 months.
- All relevant legislation is complied with.
- This should be a regular occurrence of waste, and subsequently should be collected at least once a month.
- If the waste remains on-site temporarily before it is removed, the waste should therefore be stored in line with the assessment criteria outlined in WST 01.
Note: it is
not possible to award credits for the same waste stream twice. For example, a take-back scheme for cardboard, as well as a recycling point for cardboard in the centralised waste storage location, can only be considered to be one waste stream.
Amenities – Postal facility - KBCN0114
The wording ‘post box’ is intended to allow greater flexibility than previously given, to recognize the changing nature of postal services in the US and internationally.
For example, in the US it would now be considered compliant for a building operator to have an in-house postal delivery and collection service provided by the US Postal Service, where this is available to all building users. External post boxes and post offices are also still compliant.
Amenities – Postal facility - KBCN0114
The wording 'postal facility' is intended to allow greater flexibility than previously given, to recognise the changing nature of postal services in the UK and internationally.
For example, in the UK it would now be considered compliant for a building operator to have an in-house postal delivery and collection service provided by the Royal Mail, where this is available to all building users. Naturally, post boxes and post offices are also still compliant.
Amenities – Access to cash - KBCN0359
An ATM inside a building would be acceptable provided that its opening hours are similar to those of the assessed building, regardless of whether there is a nominal charge for the service. Cash-back from the till in a retail outlet is not compliant.
Access to cash should be available to the building users at all relevant times of the day. This should not require a prior purchase of goods and should provide access to other services, such as checking account balances.
Amenities – Assessed building is one of the listed amenities - KBCN0264
Where the assessed building is itself included in the list of amenities, that particular amenity criterion can be deemed to be met, e.g. a supermarket development itself meets the proximity to food outlet required for a Retail type building.
Applicability – Management – common areas only assessment - KBCN1559
Principle
In an assessment of common areas only, building management are still responsible for the common welfare all users and for policies governing the overall asset.
Evidence
For assessments of common and tenanted areas, the scope of the manual states:
“The assessment must include evidence of a representative sample of the tenants to ensure that central management practices are in place and fully implemented in line with the assessment criteria.”
For assessments of common areas only, evidence is required from building management only.

Applies to asset-wide environmental policies only.
Answer D can apply to improvement targets for common areas only, where this can be separated from tenant targets. |
Man 05 Green lease |
Where there are tenants occupying the asset, this issue is not filtered out.
Consideration of green contracts are within the control of building management regardless of scope. |
Applicability – no occupied spaces - KBCN1551
Principle
Where:
- The scope of assessment covers no occupied spaces and,
- There is no valid way to filter credits from that issue,
Credits specifically related to occupied space are not awarded.
Outcome

Applicability – tenanted assets with common areas - KBCN1593
Principle
- Waste generated in common areas is the responsibility of building management.
- Waste generated in tenanted areas is the responsibility of the tenant.
- The asset as a whole meets the aim and criteria of the issue.
Common areas
Common areas must include:
- Bins for general waste AND
- Bins for recycable waste.
Segregated or commingled.
Mixing recyclable and non-recyclable waste in one bin is not acceptable, even if recyclable content is extracted later from the mixed waste.
If the recyclable waste is commingled, the waste collector demonstrates that they separate commingled waste in the minimum number of waste streams defined in the methodology.
Tenant or building management controlled areas
The issue criteria can be met through multiple storage areas, or a central store.
Where there are multiple storage areas, the space requirements for Answer C or D can be calculated based on the combined area of all storage areas.
The waste storage area requirements for tenants and building management must be calculated separately as stated in the manual.
Apportioning Water Consumption – common areas only assessment - KBCN1679
For assets where only the common areas are being assessed, the water consumption targets and actual figures reported should be based on the water used within the assessed areas only.
Therefore, where metering is provided for the whole building consumption and no separate metering of common areas is available, a logical assessment of the sanitary (and other) water use and distribution should be carried out so that the figures are based on an accurate estimation of water usage within the common areas. Apportioning must not be based purely on the percentage of floor area.
A logical assessment could be based, for example, on the percentage of water using equipment installed, such as the proportion of toilets/taps/dishwashers etc within the scope of the assessment against those outside of the scope.
Justification and calculations should be provided within the evidence to support the reported figures.
Assessing industrial spaces – exemptions - KBCN0734
The thermal comfort criteria do not apply to the operational or storage areas typically found in industrial assets or other similar asset types. The criteria is still be applied to the other parts of the asset as appropriate.
Operational and storage areas often have function-related thermal requirements determined by operational or storage needs. These functional requirements override the needs of any occupants.
17-Jan-2024 - Scheme applicability updated.
Assessing multiple buildings in BREEAM In-Use - KBCN0840
This version of BREEAM In-Use has been superseded by Version 6.
For assessment multiple buildings under BREEAM In-Use Version 6, please see:
09 Aug 2024 - Updated to reference guidance for current BIU standards
BREEAM In-Use has been developed as an environmental assessment method to assess existing assets. Typically, an asset consists of a single building or part of a single building. In certain circumstances, multiple buildings can be classified as a single asset by a client. This is often the case where buildings are of similar physical structure and built form, have common building servicing strategies and common management arrangements.
To assess multiple buildings as a single asset using BREEAM In-Use, the criteria listed below must be confirmed by a licensed BREEAM In-Use Assessor. This will ensure a meaningful outcome of the performance of the asset. The Assessor will be required to demonstrate how each of the criteria has been met and provide evidence to support the decision. Where there is any doubt in the criteria being met, the Assessor must contact the Technical team in advance of the certification submission for approval and will need to submit evidence of the approval along with the assessment.
Criteria:
All buildings must have the same building function, similar performance, and be of the similar design and age.
Buildings must be connected to and share common services to meet the comfort and sanitary demands of the occupants. This includes: heating, ventilation, cooling and hot water. Or, if these services are provided locally, identical servicing strategies as well as specification of equipment must be applied across all buildings.
All buildings must share similar building envelope (the physical separator between the interior and exterior of a building) and structural specifications. Buildings do not need to be physically connected, however: the specification of the envelope must be largely the same to ensure that the performance of each building fabric is comparable in terms of the range of assessed characteristics including thermal efficiency.
Building management and maintenance policies, procedures and approach must be the same across all the buildings that make up the asset to ensure consistent implementation.
All buildings must be located on the same site. The boundary of the site must be drawn where responsibility of management or ownership of the site changes.
The Assessor must collate the required evidence from each building that is included in the asset and where performance against the BREEAM requirements varies, the final score will be determined by the space with the lowest level of performance.
If alterations are made to the management and the physical structure of the asset that in turn changes the applicability of the eligibility criteria above, re-certifications must be undertaken at a building level if the Multiple Buildings approach is no longer applicable.
Please note: if the buildings differ from each other in a number of areas, a multiple buildings approach has limited value to all parties involved. In such cases, the rating will not clearly identify the areas for improvement within each building. By assessing the buildings separately, the granularity of the assessment is increased which will in turn provide owners with more detailed information on how improvement plans can be rolled out.
Assessing multiple commercial buildings - KBCN1686
BREEAM In-Use has been developed as an environmental assessment method to assess existing assets. Typically, an asset consists of a single building or part of a single building. However, BREEAM In-Use provides an exception where certain criteria have been met, and this is set out in the relevant Technical Manual under the Eligibility Criterion 5 and reproduced below with clarifications noted in Italics.
The requirements to assess multiple buildings as a single asset
Criterion 5 states: An asset cannot normally include more than one building. The only exception is where several buildings meet the following criteria:
a) All buildings must be located on the same site. The site boundary must be drawn where responsibility for management or ownership of the site changes.
The site interior may include public roads, such as industrial or office business parks, but the properties on which the buildings sit must otherwise be contiguous.
b) All buildings must have the same building function, similar performance, and be of similar design and age.
This includes Subtype as well as Type. For example, three Industrial buildings, all of which function as warehouses, could be grouped. However, if one is a cold storage facility, another is advanced manufacturing, and the third is warehousing, this would not be acceptable.
c) Building management and maintenance policies, procedures and approach must be the same across all the buildings that make up the asset to ensure consistent implementation.
Where maintenance policies, procedures, and approaches are the tenant’s responsibility through the leasing arrangements (for example, in industrial properties), these can vary, but overall building management needs to be the same for all properties.
d) Evidence must be collated from each building that is included in the asset and where performance against the BREEAM requirements varies, the final score will be determined by the space with the lowest level of performance.
The whole data set for all buildings in the assessment must be gathered and provided to the Assessor by the Client.
Demonstrating compliance for certification
- The Client will be required to demonstrate how each criterion has been met and provide evidence to support the approach.
- The Assessor must then confirm the criteria have been met through their evidence review and on-site verification.
- Site level assessments, such as an outdoor retail asset, should use a floor-area-weighted average method can be used to confirm compliance.
- For other commercial or residential assessments involving multiple buildings, representative sampling is permitted to confirm compliance. Assessors are required to confirm that the worst-case performance was applied by the Client. Assessors are required to create and document a robust representative sampling method and demonstrate that they conducted their assessment in accordance with their methodology.
- Where the Assessor is unsure how to interpret or apply the criteria, they should contact the Technical Team for clarification using the BREEAM Projects webform before submission for certification. Where relevant, a copy of the technical clarification response should be submitted as supporting evidence.
Considerations before undertaking this approach
- The rating will reflect the worst performance of all the buildings included within the assessment. This will limit the visibility of buildings within the grouping that may have better performance and opportunities at individual assets to improve performance. Assessing the buildings separately allows for the granularity of the assessment to provide owners with more detailed information on how improvement plans can be rolled out and the value to be gained from driving performance.
- Should the buildings be sold individually, the certification status does not transfer with the individual buildings. The building(s) sold would need to undergo the full certification process, including benchmarking and the on-site visit with a licensed Assessor, to be considered certified and claimed by the new ownership.
- The certificate may be updated through a mid-cycle process to remove the assessed area of the building(s) sold. This could increase the score if the building sold represented the worst-case performance. If the building removed from the certification formed the basis of the score as the worst performer, the Assessor would need to complete another site visit for the mid-cycle to ensure that the new data representing the worst performance is accurate.
Assessing multiple residential buildings - KBCN1687
BREEAM In-Use has been developed as an environmental assessment method to assess existing assets. Typically, an asset consists of a single building or part of a single building. However, BREEAM In-Use provides an exception where certain criteria have been met, and this is set out in the relevant Technical Manual under the Eligibility Criterion 5 and reproduced below with clarifications noted in Italics.
The requirements to assess multiple buildings as a single asset
Criterion 5 states: An asset cannot normally include more than one building. The only exception is where several buildings meet the following criteria:
a) All buildings must be located on the same site. The site boundary must be drawn where responsibility for management or ownership of the site changes.
For multifamily assets, this means all structures within the property boundary.
For individual homes, e.g. single family, townhouses, this means the properties on which the homes are located are contiguous.
b) All buildings must have the same building function, similar performance, and be of similar design and age.
Multifamily projects, such as garden style apartments, can still be grouped together under these criteria, even if they include different unit types.
c) Building management and maintenance policies, procedures and approach must be the same across all the buildings that make up the asset to ensure consistent implementation.
Where maintenance policies, procedures, and approaches are the tenant’s responsibility through the leasing arrangements, these can vary, but overall building management needs to be the same for all properties
d) Evidence must be collated from each building that is included in the asset and where performance against the BREEAM requirements varies, the final score will be determined by the space with the lowest level of performance.
The whole data set for all buildings in the assessment must be gathered and provided to the Assessor by the Client.

- The certificate may be updated through a mid-cycle process to remove the assessed area of the building(s) sold.
This could increase the score if the building sold represented the worst-case performance. If the building removed from the certification formed the basis of the score as the 'worst-performing', the Assessor would need to complete another site visit for the mid-cycle to ensure that the new data representing the worst performance is accurate.
Assessments of owner-occupied or common areas only assets - KBCN0804
In situations where an asset is owner-occupied, or if there are no tenanted areas within the assessed area, it is still possible to achieve credits under MAN 11. Instead of awarding credits based on green leases with tenants, credits can be awarded based on the owner/manager having in place policies/processes outlining specific targets (considering at least energy, water and waste efficient practices) applicable to the assessed area.
With regards to the evidence required in this scenario: the assessor must submit documents (which could include, but are not limited to, contracts or policies) that outline how the owner/manager has set and measured these targets.
Assessor comments submitted within BREEAM In-Use assessments - KBCN0962
Assessor comments are an extremely important part of the certification process, and are used to give the Quality Assurance (QA) team at BRE Global an understanding on why the Assessor has awarded credits. Assessor comments must be provided for any question which has credits awarded. The comments must provide the following information:
- Explanation on why the Assessor has deemed that the asset is compliant in relation to the credits awarded.
- Explanation on where compliance is demonstrated within the evidence which has been submitted. For example, if compliance is found within a particular section of a large document, the comments should help direct the QA team to the applicable section.
- Outline any information provided by BRE Global (external to the technical manual) which supports the decision made by the Assessor. For example, Knowledge Base Compliance Notes, or responses to technical questions from the Technical team.
An example from HEA 01 (PD130 – 1.1:2016):
2 credits have been awarded as 20% of the building envelope is glazed. Verification of this figure can be seen within the calculation provided within [insert evidence name]. Please also find photographic evidence of each side of the envelope [insert evidence name], as well as the drawings for each envelope which the calculations were based on [insert evidence name].
2021 01 05 Minor change to Company references
Asset classification – co-living developments - KBCN1568
The following is a guide only. Every project is unique, and assessors must in all cases review the suitability of the criteria to determine the most appropriate asset classification.
Co-living features
Co-living developments generally combine:
- Self-contained residential apartments with private kitchens and bathrooms.
- Apartments are typically rented for long-term stay (i.e. for periods of more than one month).
- Managed communal areas for work and leisure.
- Managed common facilities.
- Managed landscaping and external areas.
Classification
- For NC or RFO, generally the most appropriate asset classification is 'Residential institutions - long term stay.'
- For BIU, it is Residential.
As a guide, assessors can also consider how their asset is classified according to local regulations.
Asset Footprint - KBCN0664
The following guidance can now be used to interpret the meaning of the asset footprint:
Building only:
- The asset is a building on its own without any associated site attached to it (for example an office tower in a city centre). In this case, the asset footprint can be considered to be the area of the asset/building only, typically the ground floor area.
- Planting, including roof- and or vertical planting, on the asset/building that is under assessment must be included in the calculation.
Building located on a site:
- The asset footprint can be taken as the site on which the building is situated. The boundary of the site must be drawn when either:
- Responsibility of management or ownership of the site changes; OR
- If a site includes multiple assets and there is a clear demarcation of the area associated with each asset, then this must be considered to be the site boundary for the asset footprint.
- The footprint of any asset that is on the site but does not form part of the assessment will be deducted from the asset footprint.
- Planting, including roof- and or vertical planting, on the asset/building that is under assessment must be included in the calculation.
- Planting, including roof- and or vertical planting, on other assets/buildings than the one under assessment must be excluded from the calculation.
Calculation methodology for LE01
Percentage planted area = [Total area planted (m²) / Asset footprint (m²)] x 100
GdT 08/12/16 - Added additional guidance on deducting area from asset footprint.
Asset performance eligibility criteria – Industrial assets - KBCN1471
The following guidance seeks to clarify how the eligibility criteria within the Scope section of the technical manual should be interpreted, particularly (though not exclusively) for industrial-type assets.
1) The asset must be a complete and finished structure.
A complete and finished structure means an enclosed, permanent structure with a roof and walls intended to accommodate people and/or processes.
a) Asset Performance
No more than 20% of the Gross Internal Area (GIA) can be classified as ‘unfitted’ at the point of submission. The assessment information provided must be correct at the point of submission to BRE Global for certification
To demonstrate that no more than 20% of the GIA (the assessed area) is ‘unfitted’, 80% of the GIA of the asset must be ‘ready for occupation’. This means it must be in a finished state, ready for occupation, or already operating in the intended function/process. This ‘finished’ state could be a controlled environment for a manufacturing process, warm or cold storage, IT or other technical operation. Alternatively, this could be an unconditioned internal environment, such as storage or packing and where most likely the only service fitted is electric lighting.
The requirement for 80% of areas to be operational or ready for occupancy applies to the total assessed area, including areas fitted out for processes and spaces conditioned for human occupancy.
2) The asset must contain occupiable or occupied space(s) which is designed to be continuously occupied for 30 minutes or more per day by a building user.
This is required to assess some criteria and award credits relating specifically to human occupation.
In order to demonstrate that a space is designed to be continuously occupied for 30 minutes or more per day by building users these spaces must be conditioned for human occupation and provided with basic services. Some examples of asset areas that meet this definition are offices, homes, retail, leisure areas which have ventilation, light and energy and water supplies, e.g. heating and/or cooling and access to a toilet and hand washing facilities.
However, process-based assets, which have any areas that are environmentally controlled by building services systems for human occupation OR processes, are eligible for assessment.
a) Asset Performance
An asset not yet occupied can still be assessed.
Provided that it meets the criteria above and is ready for occupation
09 Aug 2021 Criteria relating to occupied space updated
Asset performance eligibility criteria – Self-storage assets - KBCN1514
The following guidance seeks to clarify how the eligibility criteria within the Scope section of the technical manual should be interpreted for Self-Storage assets.
Defining self-storage assets
Self-storage provides space for individuals to rent and store their personal or business belongings. The storage space - also referred to as storage units - is typically rented on a month-to-month basis. This space will make up the most space for any self-storage asset type.
Typical Scenarios:
- Local electric heating and cooling to front desk and small office space (relative to storage units)
- Hot water in the bathroom for staff or the public
- Space conditioning
- Storage units are naturally ventilated
- Storage units are mechanically ventilated but conditioned only to prevent extremes of temperature
- Storage units are mechanically ventilated and conditioned for temperature, and in some cases humidity
Scope
Eligibility Criteria
Criterion 1(a): no more than 20% of the Gross Internal Area (GIA) can be classified as 'Unfitted'.
As per
KBCN1471, this means that at least 80% of the GIA “must be in a finished state, ready for occupation, or already operating in the intended function/process. This ‘finished’ state could be a controlled environment for a manufacturing process, warm or cold storage, IT or other technical operation. Alternatively, this could be an unconditioned internal environment, such as storage or packing and where most likely the only service fitted is electric lighting.”
Criterion 1(b): no more than 20% of the Gross Internal Area (GIA) can be classified as 'Vacant'.
This requirement would only apply to office or staff spaces within the Self-Storage asset rather than the storage units themselves. The Storage units must be in a condition ready to be leased but do not need to be occupied during the period of assessment.
Criterion 2: The asset must contain occupiable or occupied space(s) designed to be continuously occupied for 30 mins or more per day by a building user.
This is required to assess some criteria and award credits relating specifically to human occupation.
Within Self-Storage assets, office and amenity areas will meet this requirement. The Self-Storage space will also meet this requirement provided it has ventilation, light and energy and access to water supplies.
Criterion 2(b): The asset must have been occupied at least 12 months prior to the start of the assessment.
For Self-Storage assets “occupied” means that office areas must have been occupied and the storage units must be ready to be occupied 12 months prior to the start of the assessment.
Asset Type/Sub-type
This asset type shall be classified as
Industrial.
The asset sub-type shall be
Distribution and Storage.
Automatic control for hand washing sink faucets – Multi-residential long-term stay assets - KBCN1587
Only faucets that are specifically used in staff, communal or public hand washing sinks are required to meet the automatic control requirements set out in Criterion 1.
These requirements do not apply to residents’ private sanitary facilities in residential long-term stay assets
BREEAM In-Use Platform Migration – FAQs - KBCN1598
- Why have we made this change?
This is intended to provide a better user experience for both Clients and Assessors. The BREEAM Projects platform is faster and more stable than the BREEAM In-Use platform, reducing the risk of data loss. Unifying our schemes on a single platform will also allow us to be provide new features that can benefit all users.
- Will this change the current process?
There are some small changes to the appearance and functionality of the system and how you access the platform. However, this should not result in a significant change to how you work.
- Will this improve Operational or QA timescales?
Currently, the QA workflow for BREEAM In-Use assessments is primarily a manual process. After its migration onto the BREEAM Projects platform, the QA process will be carried out using the online tool, leading to improved efficiency in the QA assessment workflow and more streamlined processing of QA submissions.
- Will my login details change?
There will be no change to the login details for either BREEAM In-Use or BREEAM Projects users.
- Do I need additional training to use the new system?
We have designed the tool to maintain the functionality of the BIU platform. There will be some differences in the user interface, however additional training should not be necessary.
We will be sharing a system user guide in June 2023 for further support.
- Will active assessments be moved over?
Yes, assessments that are currently in-progress will be moved over.
- Will previously certified assessments be moved over?
Yes, assessments that are already certified will be moved over.
- Will I be able to see the evidence for all my assets in the new platform?
All the assets and evidence will be transferred to the BREEAM Projects platform and will work just as they did in the BREEAM In-Use platform.
However, please remember that the BREEAM License terms and conditions require Assessor organisations to maintain complete and accurate records of the assessment documentation for a period of ten years.
BRE only uses the evidence provided for the purpose of auditing and making a certification decision. We do not keep all assessment evidence once certification has been completed. Please ensure that you maintain your assessment records locally to prevent loss and to meet BRE’s terms of service.
- Will my existing credits within the BREEAM In-Use platform be moved over?
Yes, all existing credits within the BREEAM In-Use Platform will be moved onto the BREEAM Projects Platform as part of the data migration process.
- Will I be able to still access BIU platform after migration?
No. The BREEAM In-Use platform will be retired after the migration has been completed.
- Is the BREEAM Projects platform available in different languages?
Yes. There is an option to switch languages within the platform. This will change the display language of the interface and, where supported, within the technical guidance This will be available in the following languages:
- English – UK
- Chinese
- English – USA
- Norwegian
- Will it be possible to request an invoice for BIU credits in BREEAM Projects?
The payments process for purchasing BREEAM In-Use credits will not change. It will still be possible to purchase BIU credits using a credit/debit card, as well as being able to request an invoice via a cost proposal.
- Is the log in process the same for Clients and Assessors?
Yes, the process to log in is the same for clients and assessors. Each will use their existing credentials to log into BREEAM Projects. The tool will then identify the user and display the relevant pages.
- How do I access BREEAM Projects?
You can access BREEAM In-Use using this BREEAM Projects link:
https://tools.breeam.com/projects/login.jsp
- How do I log in from the USA or China?
Our Clients and Assessors in the USA or Chinese markets will be able to log in using the same login credentials that they currently use on the BIU Platform. They will also be provided with an option to switch the language within the tool.
- Will I have the ability to work in local currencies?
No additional currency support has been added to the platform as part of this migration.
- Will the terms of use change when we move to the Projects Platform?
All users, when accessing BREEAM Projects for the first time, will be required to agree to our ‘Terms of Use’ for the system. These Terms will not be too different from the existing ‘Terms of Use’ within BREEAM Projects and BREEAM In-Use platform. Whenever updated ‘Terms of Use’ are issued, users will be prompted to read and accept these before accessing the system.
- How do I contact BREEAM for support?
Assessors are encouraged to submit all queries using the
webform, which can be found via the
Assessor Support tab in BREEAM Projects. This provides drop-down menus to select the Department/Area and to choose further options, to ensure that your query goes to the correct team.

Updated Process for Uploading Evidence
28 July 2023 FAQ 19 added
BREEAM Projects – basic asset details – asset constructed over different years - KBCN1626
Where different parts of the asset have been constructed over different years, in Basic Asset Details enter the year representing the largest proportion of floor area.
For example, if 60% of the asset area was constructed in 2008, and 40% in 1993, use '2008' as the year of construction.
Building Details – Asset Types and Subtypes - KBCN1413
BREEAM USA In-Use can accommodate assets with a wide variety of space use types.
These space uses are included in the online tool to refine the Energy Calculators for Parts 1 and 2. The table in the link below describes the space use types that can be accommodated and the corresponding Asset Type and Subtype that should be selected in the online tool.
If the space type you need is not described or you are unsure which is correct, please submit a Technical Question describing the space use type to [email protected]

Calculating the percentage of tenants - KBCN0805
Where calculations are undertaken to determine the percentage of tenants covered by a compliant green lease agreement, only those tenants that are part of the assessed area must be taken into account. Where tenants are not part of the BREEAM In-Use assessment, they must be excluded.
Please note: the calculation for the percentage of compliant tenants must be based on the number of tenants, not on the floor area.
Car sharing group - KBCN1510
The term, ‘car sharing group’, as a sustainable transport measure, may be interpreted differently. For the purposes of the BREEAM Standards, therefore, the following additional guidance should be applied, to support assessors’ understanding of the criteria, when determining compliance.
Aim:
The aim of this measure is that the asset’s management establishes, promotes and administers a process which encourages building users to share private car journeys to and from work, thus reducing the number of cars used for this purpose.
Principles:
A car sharing group will, generally:
- Be available to all building users who normally travel to work by private car
A car sharing group is not:
- A vehicle hire/loan scheme
- Intended to offset journeys which would otherwise have been made by public transport or active travel modes (e.g. walking or cycling)
The criteria do not prescribe what terms and conditions should be implemented and, whilst the above principles should generally be followed, specific arrangements may vary.
However, evidence and justification must always be provided to demonstrate that the above ‘Aim’ is met.

Carbon monoxide detection – Combustion appliances located outside - KBCN1586
Where all combustion appliances are located outside in the open air, no flues pass through an occupied space and there are no enclosed parking areas, the associated credits can be filtered out as per Criterion 1
Centralised air handling units (AHU) - KBCN0941
The requirements of the:
- Second sub-metering credit (New Construction).
- Issue (BREEAM In-Use).
do not apply to centralised AHUs, where it is not technically feasible to sub-meter energy use by separate functional, tenanted or floor areas.
The credit(s) will be assessed based on the remaining applicable energy uses.
06-Mar-2024 - Scheme applicability extended to V6.
Clarification – access to daylight - KBCN1648
Q11 of this issue asks 'what percentage of lit asset floor area has access to daylight?'
For this issue, 'access to daylight' means:
Spaces daylit from the side
- Is within 8m of a wall with openings that allow daylight in AND
- Openings comprise ≥ 20% of the wall area, as viewed from the inside.
For windows, the opening size is defined by the inside edge of the window frame, ignoring any transoms or mullions in the glazed area itself.
Spaces daylit from above
- Any spaces, or parts of a spaces illuminated by overhead openings, light tubes, or other daylighting strategies.
Where the daylighting strategy only covers part of a space, the assessor can use their judgement to define which areas have 'access to daylight' based on the specific design and lighting conditions.
Clarification – percentage of end uses - KBCN1650
This percentage is measured by the energy consumption (kWh) of significant energy uses, not by the number of end uses.
Clarification of ‘Hazardous Chemical’ - KBCN1111
A 'hazardous chemical' can be considered to be any substance that is not found naturally in the environment, which has the potential to cause damage to the environment or the health of the building occupants (e.g. oil, fuel, solvents, pesticides, biocides, etc.).
Combined sub-metering – electric space / water heating and small power - KBCN00068
For bedrooms and associated spaces in:
- Multi-residential or residential institution building types (New Construction).
- Hospitality or supportive housing asset types (BREEAM In-Use).
It is acceptable for an electric space or water heating system to be combined with lighting and small power, provided that sub-metering is provided for each floor plate or other appropriate sub-division.
For these asset types, sub-metering electric heating in multiple bedrooms may be costly and technically challenging. Where occupants have individual control but are not responsible for paying the utility bills, the building manager may have little influence on their energy consumption. Therefore, sub-metering electric heating would provide little or no benefit in meeting the aim of the issue.
06-Mar-2024 - Scheme applicability extended to V6.
15-Dec-2023 - Title updated to clarify that this approach can be applied to both space heating and domestic hot water heating, where appropriate.
Combined system for heating / cooling and domestic hot water - KBCN0329
It is permissible to have combined metering for a shared on-site or district system that combines heating / cooling, and domestic hot water generation.
In all cases, justification is provided in the QA report for the combined metering, and explains why it is not technically feasible to provide separate meters.
21-Sep-2022 Applicability of KBCN added to BIU V6. Amended to include district heating and cooling networks.
Compliance: Applicability of criteria to scheme’s previous versions - KBCN0430
Criteria set for a scheme version are not applicable retrospectively to previous versions.
Condition survey – refurbishment in the last 5 years - KBCN1522
Where an asset has been refurbished, refurbished elements listed in criterion 2 can be excluded from the condition survey if:
- The refurbishment was carried out less than 5 years ago.
- The refurbishment addressed any and all major defects with the element.
- The records of the refurbishment allow asset management to effectively maintain that element.
The intent of Rsc 01 is to give asset management a complete understanding of the condition of the asset. The requirement for 5 years is to make sure that this information is relatively up-to-date, and allows effective maintenance of the asset and management of any minor defects.
All example scenarios below assume that the refurbishment was carried out less than 5 years ago. Any refurbishment works carried out more than 5 years ago must follow the full criteria of this issue.
[accordion]
[accordion_block title="Scenario 1"]
A major refurbishment to a Commercial asset covered and effectively documented refurbishment to:
a. Structure.
b. Mechanical components.
c. Electrical components.
d. Plumbing.
e. Fire protection.
It did not cover:
f. Communications and life safety systems.
g. Health and safety conditions.
All major defects were resolved.
Credits for the condition survey, and for rectifying defects are awarded based on elements f. and g. only.
[/accordion_block][accordion_block title="Scenario 2"]
A major refurbishment has covered and documented all items in criterion 2. All major defects were resolved, but there are some outstanding minor defects that are being monitored and maintained by asset management.
BIU V6: This issue is filtered out as per criterion 1.
BIU 2015: The relevant credits are awarded.
Minor defects are common after major building or refurbishment works, and typical building contracts provide a period for the resolution of minor defects. As long as major defects are resolved by the refurbishment, and asset management are aware of and managing minor defects, these items can be excluded from the condition survey.
[/accordion_block][accordion_block title="Scenario 3"]
A major refurbishment covered all elements, but there is no record of the refurbishment of mechanical and electrical components.
A condition survey covering these items is required. Relevant credits are awarded for surveying and addressing any defects for these elements.
[/accordion_block]

Considerations for small power - KBCN1202
The reference to small power in Assessment Criterion 1 was a publishing error. This does not need to be considered when assessing this question.
Considerations for small power - KBCN1202
The reference to small power (assessment criterion 1) was a publishing error, this does not need to be considered when assessing this question.
Control of glare from sunlight – hotel rooms - KBCN1087
The primary function attributed to hotel rooms is that of a bedroom and as such, lighting and resultant glare are not considered to be problematic for these spaces.
The only exception to this is where designated additional office space is provided. In these circumstances it is the role of the assessor to determine if individual spaces should be determined as ‘relevant building areas’ in accordance with guidance provided.
Glare control criteria apply to building areas where lighting and resultant glare could be problematic for users.
01 Nov 2023 Applicability to BIU V6 Commercial confirmed
This KBCN aligns with KBCN0666 from UKNC 2014
Cycle facilities – Separate showers within shared gender-specific (single gender) facilities - KBCN1601
Cultural norms and expectations in relation to privacy may vary. The guidance on providing separate showers in the above situation is, therefore, clarified as follows:
Where showers are not divided into individual cubicles, or are only partially separated, this does not preclude compliance. However, the assessor must be satisfied and provide justification that the arrangements are in line with local custom and appropriate to the building type and the demographic of building users.
Cycle spaces – Minimum and maximum requirements - KBCN0637
These remain applicable where the 50% reduction allowed for building locations with a high level of public transport accessibility is in effect.
This means that, for instance, a large retail will still need to provide at least ten customer cycle storage spaces and could meet compliance with a maximum of fifty.
22-Nov-2023 Scheme applicability updated.
18-May-2017 Previous KBCN on large retail adapted to include any minimum requirement for cycle storage spaces.
Cycle spaces – Folding bicycles and scooters - KBCN00024
The provision of cycle storage that is only suitable for folding bicycles or scooters is not compliant.
Providing reduced storage space for folding bicycles or scooters in place of compliant cycle storage may limit future travel options.
14 03 2018 Wording clarified and reference to scooters included.
Cycle storage – 50% reduction applies to all users - KBCN1631
Where a 50% of reduction in required cycle storage spaces is allowed for any reason (for instance, for meeting a threshold for good public transport accessibility), this applies to
all asset users. This includes staff, and any applicable users such as customers, visitors or residents.
However, any minimum or maximum requirements remain the same. See
KBCN0637.
This principle aligns with BREEAM New Construction and Refurbishment and Fit-Out.
Cycle storage – Multi-residential long-term stay - KBCN1592
For the purposes of calculating the cycle storage requirements, residents should be considered as 'staff'.
Cyclists’ facilities – Combining different facilities - KBCN0683
Cyclists’ facilities can be combined, provided that all relevant compliance requirements are met and it is demonstrated that there is no conflict impacting on their use. For example, compliant showers can be combined with compliant lockers in one room, subject to the principle below.
For combined facilities to count as multiple facilities, they must be capable of being used independently of each other at the same time (where relevant) with reference to any space requirements, access, gender and privacy issues.
11 Jan 2023 - Applicability to BIU V6C confirmed
Cyclists’ facilities – Multi-residential / residential institutions - KBCN0967
Where there is a BREEAM requirement for residents, compliant facilities within their accommodation can be considered as cyclists' facilities. Separate facilities for staff must be provided as required to achieve compliance.
22 Aug 2023 Applicability to BIU USA Commercial V6 confirmed.
Cyclists’ facilities – to match additional bicycle spaces - KBCN00093
The minimum number of showers/lockers/changing facilities required for BREEAM compliance is determined by the minimum number of compliant bicycle spaces required, not by how many total compliant bicycle spaces have been provided. Where more than the minimum number of compliant cycle spaces has been provided, there is no requirement to provide more than the minimum number of showers/lockers/changing facilities.
01 Feb 2022 - Applicability to BIU USA Commercial V6 confirmed
Cyclists’ facilities – Within toilet facilities - KBCN00050
Showers compliant with the criteria for cyclist facilities should not obstruct the use of general and disabled toilets. They are not compliant unless it can be unequivocally demonstrated that these cyclist facilities are provided in addition to toilet facilities provided for persons with disabilities and general building users.
To ensure that there is no conflict between the use of general or disabled restrooms and the use of cyclist facilities.
Cyclists’ facilities – Within toilet facilities - KBCN00050
To comply with the criteria for cyclist facilities, showers should not obstruct the use of other facilities. Where a shower is located in a room with a WC, this cannot be considered compliant, unless it can be unequivocally demonstrated that the WC is provided over-and-above the requirements of relevant standards or regulations for general and disabled WCs.
To ensure that there is no conflict between the use of general or disabled WCs and the use of cyclist facilities.
25.10.18 KBCN reworded to improve clarity.
Determining boiler efficiency - KBCN1223
The boiler efficiency should be based on the Higher Heating Value (HHV) or the Gross Calorific Value (GCV). Where the information related to the efficiency of the boiler is only available in Lower Heating Value (LHV) or Net Calorific Value (NCV), it will need to converted using the following formula:
HHV = LHV x 0.9
GCV = NCV x 0.9
District heating / cooling / hot water – entering data into the Online Platform - KBCN1536
For assets which use district heating / cooling / hot water, information on the district systems are entered into Ene 09a and 09b.
In Ene 05 / 06 / 09, answer 'no' to first question
"Is space heating / cooling / hot water generated on-site?" then navigate to:
- Ene 09a to answer questions on district cooling.
- Ene 09b to answer questions on district heating and hot water.
A district heat network will also provide hot water, so information on the system which provides both is entered into Ene 09b.
The Online Platform differs from the manual structure, however it does not affect scoring in any way. All data entered contributes to the asset energy calculator.
Assets with on-site and off-site systems
Only answer questions on the system which provides the most signifcant heating or cooling to the asset. If an asset includes both on-site and off-site systems, choose the one which delivers the most energy annually.
Durable and resilient features – Features not present - KBCN1547
The requirements of Rsl 04 aim to minimize the frequency of building component replacement. Options D, E and F relate to specific features that are vulnerable to damage through the building's operation. Therefore, if it can be demonstrated that an asset does not include any such features, this requirement can be considered met, because there is nothing to protect.
Evidence confirming the above must be referenced and provided in the assessment.
It is unlikely that Option C will not apply in a commercial asset. However, if an assessor believes this to be the case, they should contact BREEAM Technical with full details and justification.
20 Oct 2023 - Applicability to BIU V6 Residential removed - Options can be filtered out where not applicable
14 Dec 2022 - Updated to include Options D and E, in addition to the reference to Option F.
Ecological features – Answer D – Planters and planted areas - KBCN1543
Outdoor planters and traditional planted areas can be considered as
one feature for the purposes of Answer D, provided there is enough planting on the site to meet the intent of the issue.
To meet the requirements of Answer D, the following must be demonstrated:
- Outdoor planters, containing live plants and/or traditional planted areas
- Other planted areas such as green roofs or green walls
- Features to assist local fauna
20-Dec-2023 – The intent of this KBCN was to simplify compliance with Answer D. This has now been updated to clarify that it only applies to Answer D, thereby removing the potentially negative impact on meeting the requirements of Answer C.
Effective Flush Volume (EFV) example calculation - KBCN1411
Effective flush volume (EFV) is the volume of water needed to clear the toilet and transport any contents far enough to avoid blocking the drain. The effective flush volume of a single flush toilet is the volume of water used for one flush.
The effective flush volume of a dual flush toilet is the ratio of full flush to reduced flush. This is taken to be one full flush for every three reduced flushes for non-residential buildings.
The effective flush volume would therefore be calculated as follows, using a 1.6/1.28 gallon dual flush volume toilet as an example:
Electric vehicle charging stations – Availability - KBCN1128
This option requires the number of electric vehicle recharging stations (EVCS) to be based on a percentage of the total car parking for the building.
To meet compliance, the intent is that recharging stations be available to all building users, including customers and visitors. However, where overall parking numbers are low, it may be difficult to effectively distribute the EV charging spaces between general users and priority groups.
In such cases, the design team must provide evidence that this aspect has been considered when locating the EV spaces, however, the decision on how to distribute these may be made by the client or, for speculative development, by an appropriate member of the design team.
In situations where parking is limited to priority spaces only, the above guidance still applies.
11 Jan 2023 - Applicability to BIU V6C confirmed and updated to allow more flexibility in relation to how EV spaces are allocated.
02 Jun 2020 updated to clarify how this applies where the only on-site car parking is for special user groups.
Electric vehicle charging stations – faster charging - KBCN1497
The number of electric vehicle charging stations required for compliance cannot be reduced by installing faster/higher power charging stations.
This would not necessarily increase the availability of the charging stations for users.
Eligibility criteria – BIU USA Residential V6 - KBCN1668
The Eligibility Criteria for BIU V6 Residential have been updated, and the guidance below supersedes Criterion 2 in the V6.0 technical manual:
Criterion 2)
a) Submission for certification must be a minimum of 12 months from completion of the dwellings.
AND
b) For a Part 2 assessment, 12 months’ utility consumption data must be available for a minimum of 80% of the dwellings.
AND
c) The asset must be intended to be a primary residence of the occupants.
Energy – MBtu definition - KBCN1423
The abbreviation MBtu can have two differing definitions. For the purposes of BREEAM In-Use, the following will be used:
Energy Consumption Reporting – common areas only assessment - KBCN1698
For assets where only the common areas are being assessed, the energy consumption targets and actual figures reported should be based on the energy within the assessed areas only.
Please note that where the asset does not have consumption data which covers the assessment area only, the BREEAM In-Use International Energy Allocation Calculator should be used when completing the Management Performance Energy Category.
Energy consumption reporting – Link to Man 04 - KBCN1612
The link to meeting compliance with Man 04, outlined in Ene 23 Criterion 1 is incorrect and should be disregarded.
Answer option D in Man 04 includes targets for Energy, Water and Waste. Whereas the intent of Ene 23 relates to targets for Energy only. This will be updated in the next reissue of the technical manual.
Enhanced waste collection in the asset - KBCN1528
Where the asset collects 6 or more unique residential waste streams on-site, answers G and H are available without the need for additional off-site collection points.
If the asset can provide enhanced waste collection and sorting on-site, then this is effectively the same as having a compliant collection point in the local area.
Example scenarios
[accordion]
[accordion_block title="5 waste streams on-site"]
An apartment building has compliant facilities or kerb-side collection for 5 residential waste streams. There is no collection for composting or garden waste.
The asset achieves the requirements for answer C only if all relevant criteria are met. There aren't enough waste streams to meet the threshold for answer G.
[/accordion_block]
[accordion_block title="7 waste streams on-site"]
An apartment building has compliant facilities or kerb-side collection for 7 residential waste streams. There is no collection for composting or garden waste.
The asset achieves the requirements for answer C, and answer G if all relevant criteria are met.
[/accordion_block]
[accordion_block title="7 waste streams on-site, with off-site collection point within 0.3 miles"]
An apartment building has compliant facilities or kerb-side collection for 7 residential waste streams. There is no collection for composting or garden waste.
An off-site collection point within a compliant distance can collect 5 waste streams, however only 2 are unique (different from what the asset already collects on-site).
In total there are 9 unique waste streams collected on-site, kerb-side, or within a compliant distance.
The asset achieves the requirements for answer C, and answer H if all relevant criteria are met.
[/accordion_block]
[/accordion]
Erratum – scope of issue - KBCN1498
Criterion 1 states:
"Where external lighting or car park lighting are not necessary from a safety perspective, the associated credits can be filtered out of the assessment."
What this means is:
- Where external lighting does not exist, filter out the relevant credits.
- Where car park lighting does not exist, filter out the relevant credits.
- Whether or not the lighting exists for safety reasons has no effect on credit filtering.
The inclusion of the word 'safety' in this criteria is misleading and will be removed in future versions.
28-Feb-2024 - Wording clarified.
Erratum – up to V6 – methodology – no default energy assumptions - KBCN1630
The scope of the issue applies only to systems with
significant energy use.
The methodology section states that the online platform will calculate
default values, and use this to indicate which systems are in scope.
This is incorrect, as default values are
not automatically calculated.
The energy use of each system will need to be manually estimated. This can be done based on:
- Typical benchmark values, and / or,
- Estimates based on the capacity of equipment, and annual equivalent full load hours of use.
Erratum – up to V6.0.0 – compliant cycle storage - KBCN1595
Criteria
Instead of answer C, criterion 3 should refer to answers D and E.
Evidence
The criteria references for this issue are incorrect, and will be corrected in the next re-issue.
Checklists and tables
- Answer D awards 2 credits for achieving the minimum number of cycle storage.
- Answer E awards 1 additional credit for achieving additional cycle storage.
The headings in Table 20 do not match these answers. Table 20 will be revised with these updated headings:
Home size |
Answer D
Minimum cycle storage
2 credits |
Answer E
Additional cycle storage
+1 additional credit |
Studio or 1 bedroom |
1 cycle space / 2 homes |
1 cycle space / home |

2 cycle spaces / home |
4+ bedrooms |
2 cycle spaces / home |
4 cycle spaces / home |
Erratum – V6.0.0 – cooling efficiency parameter – EER / SEER - KBCN1560
In the asset energy calculator guidance, the parameter given for cooling efficiency is 'SEER' (Seasonal Energy Efficiency Ratio).
This is incorrect and should say '
EER'.
This affects the following tables:
|
International |
USA |
Commercial V6.0.0 |
Table 19 |
Table 18 |
Residential V6.0.0 |
Table 16 |
Table 16 |
This will be updated in the next manual re-issue.
Erratum – V6.0.0 – Functional adaptation strategy study – Timing - KBCN1706
The functional adaptation strategy study can be carried out
during the operational life of the asset.
There is
no requirement for this study to have been done when the asset was designed.
It is unreasonable to expect asset operators (some of whom have assumed management after the asset was built) to retrospectively provide an adaptation strategy during the design process.
The following evidence requirement is incorrect and will be amended in future revisions.
Erratum – [BIU V6 Rsl 06] – Incorrect evidence requirements for answers G – H - KBCN1696
Please note that the requirements for the report to include 'opportunities identified' and the 'key metrics' does not align with the criteria requirements. This can therefore be disregarded.
This will be updated in the next reissue of the manual
Erratum – [BIU V6.0.0 Wat 14] – Incorrect evidence requirements - KBCN1695
The criterion 3 evidence requirement, "evidence of monitoring data" is incorrect and invalid. Assessments should not try to meet this requirement.
Criterion 3 requires the water strategy to have senior management approval. This has no relation to monitoring water consumption, which is already addressed in Wat 13 Water consumption reporting.
This error will be addressed in future updates.
Erratum – Electric Vehicles (EV) charging stations criteria - KBCN1701
In the BREEAM In-Use International Technical Manual, the Electric Vehicles (EV) charging criteria and their evidence were incorrectly referenced. The requirements for EV charging stations should read as follows
Answer G Electric Vehicles (EV) charging stations are provided for ≥5% of the car parking capacity.
Methodology
The methodology indicates the number of charging stations required should be calculated as a percentage of the total car parking capacity.
The ≥5% in Answer G indicates that at least 5% of the total parking spaces in the residential development should be equipped with EV charging stations.
If the number of charging facilities that should be supplied is not a whole number, it must be rounded up to the nearest whole number. For example, where the number of charging facilities that should be provided is calculated to be 10.2, the actual number of facilities that must be provided is 11.
Charging stations for Car Clubs cannot count towards the percentage provided for residents.
Evidence
The manual incorrectly referred to criterion 7 for the EV charging stations in the evidence section. The evidence requirement should refer to Criterion 5 and should be read as follows:
Criterion |
Evidence requirement |
5
|
Calculations showing the percentage and number of charging stations |
5
|
Site plan showing the location and number of electric vehicle charging stations |
Evidence of no risk – Use of Approved Standards and Weightings List - KBCN0959
The current BREEAM International Non-Domestic New Construction Approved Standards and Weightings List (ASWL) can be used as evidence to demonstrate that a country has ‘no risk’ to all natural hazards apart from flooding (which is considered within POL 02 of BREEAM USA In-Use 2016 and Rsl 01 of BREEAM In-Use Version 6).
Any country which has a weighting of 0% for Hazards within the current ASWL can provide this to BRE Global as evidence. As flooding is not included within the Hazard section of the ASWL, it must be evidenced separately. Therefore, in order to achieve maximum credits within MAT 05 or Rsl 03, the assessment must also provide evidence that the asset is in a ‘low or zero flood risk area’ under the requirements of POL 02 (BREEAM USA In-Use 2016) or Rsl 01 (BREEAM In-Use Version 6).
Note: BREEAM In-Use International Assessors who are not BREEAM International Non-Domestic New Construction Assessors, will be unable to access the ASWL. In this instance please send a technical query to BRE Global outlining the country which the asset is located, and BRE Global can confirm the current weighting for that country.
16-Aug-2016 Amended to clarify situations where there is no access to the ASWL
01-Oct-2022 Updated to apply to BREEAM In-Use Version 6
Evidence requirement 2: Design process consideration - KBCN0958
Evidence requirement 2 within MAT 07 is not required to be submitted where design level evidence is not available.
Instead of this, evidence should be provided which demonstrates that the asset has identified the areas of the asset which are susceptible to damage, and has made installations which protect against this. Examples of areas at risk could include (but is not limited to):
- Asset walls located next to vehicular traffic
- Internal wall finishes in areas of the building which are often occupied with trolleys (e.g. catering services, or healthcare)
Amended: 01/11/2017
Reason for change: Addition of '(but is not limited to)'
Evidence requirement 2: Design process consideration - KBCN0958
Evidence requirement 2 within MAT 07 is not required to be submitted where design level evidence is not available.
Instead of this, evidence should be provided which demonstrates that the asset has identified the areas of the asset which are susceptible to damage, and has made installations which protect against this. Examples of areas at risk could include (but is not limited to):
- Asset walls located next to vehicular traffic
- Internal wall finishes in areas of the building which are often occupied with trolleys (e.g. catering services, or healthcare)
Amended: 01/11/2017
Reason for change: Addition of '(but is not limited to)'
Evidence: Photographs not permitted for security reasons - KBCN0389
Where photographs are not permitted during a post-construction site visit for security reasons, in addition to any alternative evidence requirements listed in the Schedule of Evidence for each issue, the assessor will also need to provide a detailed site inspection report and/or as-built drawings (where permitted by the client). If following this approach, full justification and documentary evidence from the client will be required for QA purposes.
Evidence: Types of evidence required to demonstrate compliance with BREEAM - KBCN0402
The schedule of evidence table details the typical types of information that the assessor needs to collate to assess compliance against the requirements of a BREEAM issue. The evidence type listed against each requirement is not exclusive and other types and forms of evidence (listed or not listed in the table) can be used to demonstrate compliance against a BREEAM requirement.
Key to demonstrating compliance with the BREEAM requirements is that the assessor has used, and references, an auditable trail of evidence, regardless of the form that evidence takes in relation to each BREEAM requirement. For example: if, for a particular BREEAM requirement, the schedule asks for a letter from the client confirming compliance but compliance can or has been demonstrated via a building specification then the assessor can reference that piece of evidence as demonstrating compliance and does not need a letter.
Please note that the BREEAM team is unable to advise assessors whether a particular piece of evidence demonstrates compliance as this is the assessors responsibility. The BREEAM team will not fail the QA of a certification report on the basis that evidence referenced in the report, confirming compliance with the assessment criteria, is not an identical type to that outlined in the schedule of evidence. For further information please refer to the 'BREEAM evidential requirements' section or 'Appendices' section.
Facilities provision for public bicycle sharing systems - KBCN0276
Where a public bicycle sharing system is being used to account for up to 50% of cycle spaces provided, the total number of cycle spaces, including those provided by the bicycle sharing system, should be the basis on which the compliant cyclist facilities are provided.
This is because people using public cycle spaces will still need the use of cyclist facilities such as showers and lockers.
13.08.2018 KBCN applied to the BREEAM In-Use scheme.
Fire hydrants and sprinklers – Leak detection - KBCN0680
Where it is confirmed by an appropriate project team member that it is not possible to fully meet the leak detection criteria for fire hydrants or sprinklers, an alternative approach can be implemented for these systems.
This must demonstrably meet the aim of the issue by detecting and alerting the building management to major water leaks.
11 Sep 2024 - Applicability to BIU USA V6 and INC V6 confirmed. New guidance introduced to clarify that BREEAM compliance should not compromise the operation of building safety-critical systems.
Flood risk – Site situated across numerous flood zones - KBCN0532
Where a site is situated across more than one flood zone, the flood zone with the highest probability of flooding, i.e. the worst case scenario, must be considered for the purpose of the BREEAM assessment. An exception to this would be where the areas in the higher probability zone include only soft landscaping and it can be demonstrated that access to the building will be maintained in a flooding event.
This is to ensure that the site has adequately managed the worst case scenario level of flood risk associated with the site's location.
07/03/2018 Updated to include circumstances where an exception may apply.
Flood risk – use of flood maps only in FRA - KBCN1524
Answer option E (Commercial) or F (Residential)
If a flood risk assessment considers flooding from rivers and seas only, flood risk is zero / low, and the following requirements are met:
- There are local or national flood maps available covering these sources of flooding.
- The maps are accurate, up to date, and have sufficient detail to clearly identify flood risk for the asset.
- The maps are approved by local or national government, and based on robust data.
It is acceptable for the flood risk assessment to be carried out by a relevant member of the team. It does not require a competent individual (see manual definition) to do this.
Most sources of flooding are site-specific and require specialist input and calculation to quantify. However, flood maps meeting the criteria above can provide an acceptable level of assurance of overall flood risk from rivers or seas without the need to engage a specialist.
Answer option B (Commercial) or C (Residential)
Where the risk of flooding is medium or high, flood mitigation measures are required (criterion 3).
These mitigation measures must be defined by either:
- A local authority (the measures must be relevant to the asset).
- Or a competent individual.
The FRA can still be produced by a relevant member of the team.
Exemplary credit
This option is only available if a site-specific FRA was carried out by a competent individual, and cannot be based only on flood maps that give an allowance for climate change.
Example scenarios
[accordion]
[accordion_block title="Low / zero flood risk"]
National flood maps cover flooding from rivers and seas. The flood risk from these sources is zero / low.
The compliant FRA can be produced by a relevant member of the team.
[/accordion_block]
[accordion_block title="Medium / high flood risk"]
National flood maps cover flooding from rivers and seas. The flood risk from these sources is medium / high. Flood mitigation measures are required.
The local authority provides some general flood mitigation measures for the area, but these are not relevant to the assessed asset.
Instead, a competent individual is consulted on relevant flood mitigation measures for the asset - their recommendations are recorded in the FRA.
The compliant FRA can be produced by a relevant member of the team.

06-Nov-2024 - Answer C guidance title now corrected to point to Answer B for Commercial manuals.
Flow control devices – residential accommodation - KBCN0415
The credit for the specification of flow control devices in WC areas or facilities does not apply to ensuite facilities in residential areas, e.g. ensuite facilities in individual private bedrooms and a single bathroom for a collection of individual private bedrooms in halls of residence, key worker accommodation or sheltered accommodation. The credit and criteria are however applicable to buildings which have guest bedrooms with ensuite facilities, e.g. hotel rooms, and communal WC areas or facilities, e.g. communal WC facilities in hotels or hostels and care homes.
In accommodation where occupancy is long-term and there is a sense of ownership of the space, flow control does not need to be assessed as the occupants are likely to detect and report leaks.
26 Oct 2023 - Applicability to BIU USA V6 Commercial confirmed
Flow control devices – Use of devices on individual sanitary fittings - KBCN1550
The intent of the requirement for flow control devices is to minimize the impact of undetected wastage and leaks from sanitary fittings and supply pipework.
The use of flow control devices on individual sanitary fittings alone does not, therefore, fully meet this aim.
Flow control devices for multiple blocks - KBCN1186
The criteria are set to encourage isolation of the water supply to each WC block when it is not being used. If a single flow control device, for example one programmed time controller, is adequate to switch the water on at predetermined times that suit the usage patterns of more than one WC blocks or facilities, this can be used to demonstrate compliance.
Please note that if only one timed controller is used for a large area/number of facilities, the assessor must justify that this is appropriate to the usage patterns within the building and confirm that multiple timers would be redundant (i.e. they would all be set to the same time). Consideration should be given of any facilities that may be open longer than others, requiring these timers to be programmed differently in different areas.
As long as the aim of the credit (‘to reduce the impact of water leaks that may otherwise go undetected’) can be achieved through the specification of an appropriate number of flow control devices, the credit may still be achieved if timers cover more than one WC area/facility to prevent minor water leaks.
14 Apr 2023 - Applicability to BIU V6 Commercial confirmed
Full or Partial sub-metering - KBCN1203
Fully sub-metered
For an asset to be considered as fully sub-metered both heating and cooling consumption must be sub-metered for each tenant.
Partially sub-metered
For an asset to be partially sub-metered, the asset must have at least one tenant that has both heating and cooling consumption sub-metered. An area cannot be considered either fully or partially sub-metered where only one of heating or cooling is sub-metered.
Glare control – alternative measures - KBCN0139
Alternative forms of glare control to those listed in the guidance can potentially be accepted, if it can be justified to the BREEAM assessor that the proposed system will effectively eliminate disabling glare and the assessor accepts this.
Heating and cooling provided through one system - KBCN1204
Where heating and cooling is provided through the same system and it is not possible to separate the consumption related to each, then one sub-meter covering the system can be considered to be fully sub-metered.
Indoor and/or outdoor space – Shopping Centers - KBCN1143
The Shopping Center requirements for this issue only apply to retail assets comprising of:
- A minimum of 15 stores
or
- A floor area of at least 121,000ft2
N.B. When carrying out the assessment of common areas only, the criteria apply to the whole building rather than just the common areas.
Indoor and/or outdoor space – Shopping centres - KBCN1143
The Shopping centre requirements for this issue only apply to retail assets comprising of:
- A minimum of 20 stores
- A floor area of at least 37,000m²
N.B. When carrying out the assessment of common areas only, the criteria apply to the whole building rather than just the common areas.
Installed controls – ‘Asset does not have both heating and cooling’ - KBCN1678
In the technical manual, the intent is that Q1, Q2 and Q3 allow the credits to be filtered where the asset has 'neither heating nor cooling', in line with the assessment tool.
This will be updated in the next reissue of the technical manual.
Intakes and exhausts closer than stated in criteria - KBCN0120
If the location of the building’s air intakes and exhausts are closer than given in the manual, compliance can be achieved where they are designed in accordance with BS EN 13779:20071 Annex A2.
If the location of the building’s air intakes and exhausts are closer than given in the Technical Manual, it may be feasible to demonstrate compliance with the BREEAM criteria using alternative methods [eg wind tunnel studies, computational fluid dynamics (CFD) modelling]. If the alternative method demonstrates that the proposed location of intakes and extracts prevents recirculation of exhaust air under typical wind conditions, then the credit may be awarded, providing all other compliance requirements are met. If this cannot be achieved and the distance requirement is not met, then the credit must be withheld.
Intakes and exhausts closer than stated in criteria - KBCN0120
If the location of the building’s air intakes and exhausts are closer than given in the manual, compliance can be achieved where they are designed in accordance with BS EN 13779:2007 Annex A2.
If the required distance between intakes and extracts is not achieved through design, it may be feasible to demonstrate compliance with the BREEAM criteria using CFD modelling. If CFD modelling demonstrates that the proposed location of intakes and extracts prevents recirculation of exhaust air under typical wind conditions, then the credit may be awarded, providing all other compliance requirements are met. If this cannot be achieved and the distance requirement is not met, then the credit must be withheld.
Interlock controls – clarification - KBCN1491
An interlock is a control that is wired so that when there is no demand for heating / cooling in a space, the heating / cooling generator and the associated pumps are switched off. Use of thermostatic radiator valves (TRVs) alone does not provide interlock.
Partial interlock means that the cooling and heating interlock controls are separate. However, the control function may be set up to minimise the possibility of simultaneous heating and cooling.
Total interlock means the controls are wired so that simultaneous heating and cooling is not possible. Where there are separate local heating or cooling units present, these will also need to be wired into the control system for total interlock to avoid the possibility of simultaneous heating and cooling.
Internal lighting levels where computer screens are used - KBCN0283
For areas where computer screens are regularly used projects can specify 300 lux, as referenced in CIBSE Lighting Guide 7, rather than the levels prescribed in the standard EN 12464:2011.
07 Dec 2021 Applicability to BIU V6 Commercial confirmed.
Intruder alarm systems – apartment buildings or similar - KBCN1572
Scope
The scope of this KBCN applies to any residential asset that:
- Is comprised of multiple self-contained dwellings within a single building envelope, and
- Share common entrance(s) and circulation.
A typical example is an apartment building.
Principle
The asset as a whole is protected by systems that are fit for purpose to ensure the safety and security of the asset, its users and their property
Implementation
Security requirements for apartment buildings will vary greatly depending on factors such as:
- Scale and configuration.
- Access strategy.
- Local context.
- Which areas are under building management control.
Because of this, BREEAM cannot provide specific guidance on how intruder alarms and access control are configured to meet the principle.
It is the role of the assessor and a competent third party (for instance, this can be a 'competent person' as defined in Rsl 10) to evidence how this principle is achieved for the asset as a whole.
Evidence from a compliant security risk assessment carried out in line with Rsl 10 can be used to support this issue.
Management-based solutions
As a Part 1 issue, this intent must be achieved by systems which are intrinsic to the asset.
Management-based solutions (such as a concierge service, or security guards) cannot be used to achieve answer E (intruder alarm systems).
Answer F (alarm receiving centre) can only be achieved with a system that complies with Answer E.
Intruder alarms – Requirement for these to be audible when activated - KBCN1597
Where it is justified by the security consultant, project team or building management that a 'silent' intruder alarm system is more suited to the asset’s overall security strategy, this can be considered as meeting the Definition in our guidance.
Invoicing for BIU Certification fees - KBCN1416
Assessors or Assessor Organizations can request an invoice to purchase certification credits rather than purchase directly through the BREEAM In-Use online tool from the Finance team. ([email protected]). The Certification fees published in the BREEAM USA In-Use Fee Sheet (FS130) are chargeable to the Assessor. As our contract is with the licensed Assessor Organization, we will not invoice any third parties for any Certification fees. All invoices for Certification Fees will be issued to the Assessor Organization.
Once payment is received, the BREEAM USA team will add the credits to the Assessor’s account. It will be assumed the purchased credits are to be added to the requestor’s Assessor account unless otherwise stated.
Any questions about certification fees should be directed to the BREEAM In-Use Team ([email protected])

Leak detection – extent of responsibility - KBCN0688
For the credit to be awarded, all the pipework in a development that the owner/occupier has responsibility for must meet the leak detection criteria. In situations where third party organisations place restrictions on the pipework that can be metered, the scope of works (and hence placement of a meter for the use of leak detection) will start immediately after this point. For instance where the utility company's meter is placed midway between the boundary and the building, the scope of leak detection for BREEAM purposes will be between utility meter and the building, not to the boundary (as stated in the guidance).
The scope of the BREEAM criteria is only on pipework that the owner/occupier has control over.
Leak detection – recycled water use - KBCN0433
The leak detection requirements still apply to all relevant water systems where water recycling systems are specified for toilets and urinals.
Recycled water should be considered as a valuable resource as it replaces potable water use, and in many instances, recycling systems will still incorporate a utility-water back up.
Leak detection – using a BMS - KBCN0439
A BMS can be used for leak detection purposes if it can be demonstrated that its integrated or add-on features meet all the requirements for a leak detection system.
07 Feb 2022 - Applicability to BIU USA Commercial V6 confirmed
LZC – Local regulations and private wire arrangements - KBCN1658
Where local regulations do not permit electricity generated by on-site renewables to be connected directly to the building, and where evidence of the relevant regulations is provided at QA, the requirement for a private wire arrangement can be waived.
Minimising flicker – scope of issue - KBCN1639
Principle
Flicker from
all lighting systems is eliminated. This means eliminating flicker in:
- All lighting within management control, common areas, and tenanted areas.
- Occupied, un-occupied and external spaces.
Only emergency lighting is excluded. See
KBCN0185.
Lighting flicker is undesirable regardless of location or length of exposure.
Commercial scope
Eliminate flicker in all lighting.
Residential scope
Eliminate flicker in:
- All communal areas (internal and external, occupied and unoccupied).
- Management offices, and all areas under management control.
Minimizing watercourse pollution – Areas to be assessed - KBCN1633
Criterion 2 should be interpreted as follows:
The intent is to provide a list of areas that are likely to present a risk of watercourse pollution. All the listed areas must be considered, however, where a listed area is not present, or it is present but poses no risk of watercourse pollution, this should be justified with supporting evidence.
Where the development does not include any of the listed areas, or none of the areas present poses a risk of watercourse pollution, justification and evidence must be provided and this issue should be filtered out, in line with Criterion 1.

About ModeScore Sustainable Transport certification:
ModeScore assess and certify sustainable transport facilities and services in buildings. ModeScore encompasses ActiveScore within its assessment criteria, covering four pillars of sustainable transportation while incorporating accessibility into each:
- Public Transportation
- Environmentally-Friendly Private Vehicles
- Active Transportation
- Site-Wide Mobility
ModeScore evaluates the connectivity potential of any building in any location, offering four levels of certification with a total scorecard of 120 points. ActiveScore (Travel Facilities) counts for 10 points:
- Certified (0-39%)
- Silver (40-59%)
- Gold (60-79%)
- Platinum (80-100%)

Multi-tenanted assessed areas – Demonstrating compliance - KBCN0984
BREEAM USA In-Use requires each tenanted space to be assessed separately for each question and to determine the final score based on the tenanted space with the lowest score. An example of this question type is HEA 06, for which, to select an answer option, the relevant requirement needs to be met by all tenanted areas. For example, if there is an asset with five tenants where four tenants provide mains connected water provisions, but only one provides access to non-mains connected water provisions, only one credit can be awarded.
However, this approach is not required in the case of questions where credits are awarded based on a percentage of compliance. In these cases, Assessors should consider the entire assessed area as a whole. An example of this question type is WAT 04, where the percentage of low-water use fittings, regardless of their location in the building, is assessed in one calculation.
Multi-tenanted assessments – Demonstrating compliance - KBCN0984
The requirement to assess each tenanted space separately for each question and to determine the final score based on the tenanted space with the lowest score, only applies to what the guidance below refers to as ‘Question type 1’:
Question type 1: In such instances to award credits, each tenanted area must demonstrate full compliance. An example of this question type is HEA 06, for which, to select an answer option, the relevant requirement needs to be met by all tenanted areas. Eg, if there is an asset with five tenants where four tenants provide mains connected water provisions, but only one provides access to non-mains connected water provisions, only one credit can be awarded.
Question type 2: In such instances, the question rewards credits based on the percentage of compliance. An example of this question type is WAT 04, where the percentage of low-water use fittings, regardless of their location in the building, is assessed in one calculation.
Night-time operation – requirement for controls - KBCN1048
Projects
or areas of an asset which operate at night-time can adapt or omit the requirement to provide controls or presence detection to align with the building’s hours of operation.
This could, for example, include service yards or car parks.
The aim of this Issue is to reduce the energy use for external lighting and should not interfere with the building’s operation.
02 Oct 2024 - Updated to clarify the scope of the this guidance and applied to NC V6 and BIU.
No light liquid separators - KBCN0957
It is only possible to select the answer option 'No light liquid separators on site' within POL10, where there is evidence which demonstrates that the asset can select 'Asset does not require light liquid separators or grease separators' under POL01.
Amended: 17/11/2017
Reason for change: Correction in spelling, and removal of reference to a specific scheme.
Non-specific levels of performance within local legislation - KBCN1152
In areas where the local legislation does not specifically outline the exact requirements related to inclusivity of access, it is often difficult for asset owners to demonstrate how they exceed the legal requirements. Therefore these assets can demonstrate compliance by providing evidence that the asset meets all of the following:
The asset has features within which ensure that persons which are less able-bodied, are able to utilise the same facilities as all other building users. These include:
- Access to the asset entrance
- Horizontal and vertical (where relevant) circulation within the asset (this should be considered for normal operation, as well as emergency evacuation situations)
- Appropriate use of building functions
- Appropriate use of building controls (specification of suitable controls, switches etc.)
- Sanitary accommodation, including toilets, showers, changing facilities etc.
Alongside this, the Assessor must provide confirmation of the exact legislation which is applicable to the asset, and provide a short statement outlining the requirements within it.
Occupancy calculation – Buildings with shift patterns - KBCN0431
In buildings with shift patterns, as shifts may overlap, the building users calculation should be based on the maximum occupancy of the building at any given time.
Occupant control – spaces requiring user controls - KBCN0170
This guidance is intended to clarify the types of area for which user controls are required or would be considered beneficial.
Zoning is required in all areas of the asset where specified in the assessment criteria. Please refer to the specific requirements of the applicable BREEAM standard to interpret this guidance appropriately.
User controls required
Spaces where users are expected to have independent control over their environment.
- Owned spaces: small rooms for a few people.
For instance, cellular offices, owned spaces in residential assets.
- Temporarily owned spaces: where occupants expect to operate the environmental controls while they are there.
For instance, meeting rooms and hotel bedrooms.
- Shared spaces.
For instance, multi-occupied areas such as open-plan offices or workshops.
User controls not required
Spaces where users are not expected to have independent control over their environment.
- Managed spaces: where environmental control is expected to be centrally managed.
For instance, atria, circulation areas, concourses, entrance halls, function halls, restaurants, libraries, and shops.
- Occasionally visited spaces.
For instance, storerooms, bookstacks in libraries, aisles of warehouses, toilets.
14-Dec-2022 - KBCN applicability updated to include BIU. Wording clarified, and amended for compatibility with BIU criteria.
Off-site waste sorting / no dedicated on-site waste storage - KBCN0696
BREEAM assesses the
dedicated space for recyclable waste storage. This must be a permanent structure on-site, or space in the asset.
Where this space does not exist:
For NC or RFO
The aim of the issue is met by provide evidence covering all points 1-4:
- A waste management plan which provides on-site storage between collections, adequately sized based on the frequency of collection.
- An on-going waste recycling contract.
- The typical recycling rates from the waste management company.
- A permanent structure (or internal space) within the asset site boundary that can be converted to comply with all criteria requirements. Layout drawings must be provided showing how this space could be converted in future, including meeting all relevant criteria for:
• User and vehicle access,
• Area requirements for waste storage,
• Appropriate size and number of containers for the expected waste streams, and
• Space allowance for any additional waste processing requirements e.g. compactors, composting containers, water outlets etc.
This ensures that there is:
- A robust off-site waste management strategy,
- Proof of future convertibility for on-site waste storage.
For BIU
The above approach for NC / RFO only applies to waste storage for construction fit-outs, which are temporary in nature. It does not apply to any other credits, and compliance cannot be met based on future commitments. This means that the above approach:
- Does not apply to recyclable waste storage.
Answers C + D | Rsc 02 | BIU Commercial V6.
- Does apply to off-site sorting for construction waste arising from fit-out activities.
Answer E. Only points 1-3 apply - a future commitment for permanent storage facility is not required.
- Do not apply to the storage of reusable construction products
Answer F.
For BIU, new storage areas will be recognised once they are completed and assessed in future certification cycles.
18-Nov-2024 - Requirements for BIU projects clarified relating to all answers in Rsc 02. Title clarified.
09-Feb-2024 - Requirements clarified. Applicability updated to include construction waste storage for BIU V6 Rsc 02.
17-Jan-2024 - Scheme applicability updated.
16-Apr-2018 - Wording clarified.
On-demand public bus services - KBCN1404
These can be recognised as follows:
- The location of the transport node should be determined as the nearest available pick-up point to the assessed building
- The frequency of the service should be considered as the published maximum wait time (or actual average wait time, if the service is established and this data is available)
- Such services, whilst they may serve multiple destinations, should be considered as a single route
- It must be demonstrated that information on the availability and how to access the service is made available to building users
This is limited to genuine on-demand bus services, which are operated as public transport with multiple pick-up and drop-off points and does not extend to private hire, taxi or other similar operations.
On-site LZC – whole site shared connection - KBCN1424
To be recognised in BREEAM, the on-site Low and Zero Carbon (LZC) technology must have a direct physical connection to the assessed asset.
OR
Where the LZC technology is;
- Located on the same site,
- Is owned and managed by the same organization as the assessed building, and
- Where it is impractical to physically connect the assessed building to the system,
It is acceptable to allocate the renewable energy generated proportionally as a calculation of the asset's predicted energy consumption compared to the total energy consumption of the whole site.
To allocate renewable electricity by proportional consumption:
- Obtain the total annual renewable electricity generated on-site.
- Exclude all renewable electricity which has been exported to the grid.
- Determine the respective electricity consumption of all assets on the whole site (predicted for new builds and measured for existing assets).
Where consumption data is missing, renewable electricity must not be allocated to the assessed asset. In this case, it is assumed that all electricity consumed is sourced from the grid.
17-Jan-2024 - Applicability BIU V6 Ene 13 removed, as this approach is not applicable to assessing the area of PV fitted.
21-Dec-2022 - Applicability to In-Use V6 confirmed.
Operational energy and water use during Covid-19 lockdown - KBCN1425
As we continue to adapt to and assess the impacts of the COVID-19 pandemic, the BREEAM team is seeking to ensure that the data underpinning BREEAM in Use certification accurately reflect typical operational performance.
We appreciate that the full or partial lockdown conditions related to the pandemic may have had a significant impact on the performance of the asset particularly the operational energy and water consumption.
We trust our assessors to use their professional judgement to determine the extent that operational energy and water consumption has been impacted by the COVID-19 restrictions. They must ensure that submitted consumption data is representative of consumption under normal conditions. Clients should work with their assessors if they are unsure how they should proceed.
Assets are likely to have been affected by many different local lockdown scenarios so one approach to reporting consumption data is unlikely to apply to all situations. For example, normal consumption data is likely to be sufficient for assets that have only had a minor changes to their operations (e.g. two weeks), if the rest of the 12 month period has been unaffected.
For assets that been more significantly affected (e.g. several months of reduced occupancy), it is likely that energy and water consumption data will need to be taken from a period of time before local lockdown restrictions came into force. In this scenario, the following approach can be used:
The consumption reported must cover the 12 months prior to the restrictions coming into force. The reported consumption would need to be validated against the year prior to the reporting period to provide assurance to the Assessor that it was in line with typical operations. Additional evidence and verification will be required for submission. The following sections should help clarify how this should work:
Normal BREEAM requirements
Consumption Reporting:
- 12 months prior to submission, validated against the evidence requirements
Evidence requirements:
- Bills or other third-party evidence to support the consumption data reported for this period.
New requirements for this KBCN
Consumption Reporting:
- 12 months prior to the lockdown period validated against the 12-month period prior to the reporting period to confirm usage as “typical”
Evidence requirements:
- Bills or other third-party evidence to support the consumption data reported for this period
- Bills or other third-party evidence to support the consumption data in the validation period
- A description of the changes that took place to the property’s operations due to COVID-19 and provide evidence of the circumstances
Example for a building submitting for certification in October 2020 subject to lockdown from March 2020:
Normal reporting period
October 2019 – September 2020
Adjusted reporting period in line with this KBCN
March 2019 – February 2020
Validation period: March 2018 – February 2019
This KBCN will remain in place but will be under review as we continue to monitor the impacts of COVID-19 and amend requirements as circumstances change. We will keep assessor informed of BREEAM In-Use users and assessors via further service announcements and other communication channels.
Operational waste – No managing organisation or no tenants on-site - KBCN1584

- Where there is no on-site managing organisation and
- Within the assessment boundary, all tenants meet the operational waste criteria.
Answers C and D can be awarded.
06-Apr-2023 - Updated to cover both situations described above.
Outdoor space – Parks and other public open spaces - KBCN1588
Public parks may meet the requirements for ‘Outdoor space’ even if smoking and vaping are unrestricted, as the impact on other visitors would be minimal.
However, to ensure the above and that the overall aim is met, a compliant park must be over 27,000 sq. ft. in size and be a ‘green space’ - an area of grass, trees, or other vegetation set apart for recreational or aesthetic purposes that is publicly owned and allows free access during the hours of daylight.
Other similar areas that meet the above requirements, such as woodland or nature reserves, could also be considered as meeting the aim.
Pedestrian and cyclist safety – Small scale deliveries - KBCN1151
Where the asset only accepts deliveries on-site from small delivery vehicles (including cars or small vans), and does not require deliveries from medium to large delivery vehicles (defined as any vehicle with a wheelbase greater than 120 inches), then the credits can still be awarded if the following aspects have been met:
- Although the delivery vehicle can use the same access point, there should be a dedicated parking position for the delivery vehicle, and this should be separate from the regular parking spaces;
- Deliveries made to this asset should be infrequent, on average this should be less than three deliveries a day;
- The access, parking and turning areas for delivery vehicles are designed for simple manoeuvring according to the type of delivery vehicle likely to access the site, thus avoiding the need for a multipoint turn.
Pedestrian and cyclist safety – Small scale deliveries - KBCN1151
Where the asset only accepts deliveries on-site from small delivery vehicles (including cars or small vans), and does not require deliveries from medium to large delivery vehicles (defined as any vehicle with a wheelbase greater than 120 inches), then the credits can still be awarded if the following aspects have been met:
- Although the delivery vehicle can use the same access point, there should be a dedicated parking position for the delivery vehicle, and this should be separate from the regular parking spaces;
- Deliveries made to this asset should be infrequent, on average this should be less than three deliveries a day;
- The access, parking and turning areas for delivery vehicles are designed for simple manoeuvring according to the type of delivery vehicle likely to access the site, thus avoiding the need for a multipoint turn.
Pods or privacy booths used as workstations – Impact on view out - KBCN1697
Provided the space or room itself is compliant based on a more traditional furniture arrangement, the enclosure of workstations in booths or pods can be disregarded when considering compliance with the ‘View out’ criteria.
POL 01 – Assessment criterion 2 - KBCN1071
In order to respond to feedback, additional clarity has been provided in regards to the interpretation of assessment criterion 2.
Aim
To reduce the risk of polluting natural watercourses through contaminated surface run-off and/or
grease from kitchen facilities entering drainage systems
Assessment criterion 2
Where it can be demonstrated that drainage or wash down facilities do not lead water from inside an underground or covered area to natural watercourses, such areas comply with the requirements by default.
BREEAM aims to be outcomes based, rather than prescribing a particular way to demonstrate compliance with the Aim. Therefore, criterion 2 is designed to allow flexibility for alternative systems (to light liquid separators) to demonstrate compliance. These alternative methods must either contain or prevent the pollution from leaving the site.
By ensuring that the pollution does not enter the drainage system (i.e. leave the site), the building owner can be confident that the pollution is not entering the natural watercourse further down the drains (where there is the potential for issues outside the scope of the assessment).
Pre-payment systems - KBCN0293
Pre-payment systems do not meet the criterion for a cash machine and therefore cannot be used as an alternative.
Cash machines provide additional services for building users, such as cash to use in other shops, the checking of bank balances, which a pre-payment system would not provide.
Presence detection – illuminated signs - KBCN1671
The requirements for presence detection do not apply to illuminated signs.
In BIU V6, presence detection requirements are included as part of automatic energy saving controls. All other requirements in this criteria must still be met.
Procedures and plans for cleaning the interior of the asset – Scope of the requirements - KBCN1649
The criteria only apply to areas or systems for which the landlord is responsible for the cleaning arrangements. However, the landlord must provide written guidance to tenants on 'procedures and plans for cleaning the interior of the asset' that aligns with relevant aspects of Criterion 2.
It is not a requirement that the landlord monitors or enforces this, however, in order to meet the intent of the criteria as far as possible, evidence must be provided that such guidance has been provided to all tenants.
Note: This guidance is not intended to change the criteria, but rather to clarify the overall intent. The applicability of the requirements to tenanted areas is not stated in the technical manual. Therefore, if it can be demonstrated that an assessment has based compliance on landlord's/common areas only prior to the date of publication of this guidance, this will be accepted.
Updated guidance on the scope of these requirements will be included in the technical manual at the next opportunity.
Process Notes - KBCN0611
Process notes can be accessed by licensed assessors
here.
When a new process note has been released, you may be required to tick the box to confirm you have read the note to be able to access other documents in BREEAM Projects. To do this scroll to the bottom of the Process Note index page and tick the box and click next.
Process water to offset potable water demand - KBCN0586
Where it is demonstrated that it is safe to do so, process water resulting from the building under assessment, can be considered for off-setting potable water demand from components that would otherwise be supplied using potable water, when in line with the criteria requirements for greywater systems.
Process water resulting from the building under assessment can be considered as a form of greywater for the purposes of off-setting potable water demand.
21 Dec 2021 Additional wording added, requiring it to be demonstrated that process water is safe to use and KBCN applied to BIU standards.
Process: Registration date and applicable scheme manual issue - KBCN0708
Typically the scheme technical manual issue which is current when a project is registered should be used for the assessment. For example, if a BREEAM UK New Construction 2014 development was registered on 01/07/2016, the current issue of the scheme technical manual at that point would be issue 4.1, which was published on 11/03/2016 (the next issue 5.0 of the technical manual was published on 05/09/2016). However, it is permissible for the assessor to decide to use a later issue of the technical manual. The scheme technical manual version and issue used for the assessment should be clearly referenced within the assessment report.
Note that in any case, the same technical manual version and issue should be used for the entire assessment. It is not acceptable to assess different credits based on different issues of the technical manual and it is not acceptable to change issues between submissions of the assessment.
26 09 17 Clarification added that the 'Issue' of the technical manual may not be changed between assessment submissions
Provision of rest areas – Accessibility - KBCN1700
For an area to be considered compliant:
- Regular asset users with disabilities, (including employees and visitors), must be able to access the facility. (Answers C, D and E)
- Canteen serveries and food and drink preparation facilities do not need to be adapted for disabled users, however the rest area itself must be accessible and suitable for all regular asset users. (Answers C and D)
- Where a building has a large number of visitors, (see Specific Note 1), indoor and outdoor rest areas must be accessible to people with disabilities. (Answers C and E)
Proximity to amenities – Employee working hours - KBCN1653
The intent of Criterion 1 is that amenities must be open at times when they can benefit employees during typical opening hours for the asset type.
The guidance on 'Employee working hours' in the Definitions section should, therefore, be disregarded. However, the assessor must be satisfied that, given the working hours of the assessed building and the opening hours of the amenity, this will benefit building users in line with the aim of the issue.
Recognizing future performance - KBCN1538
BREEAM In-Use recognizes an asset's operational performance
at the time of certification.
Compliance
cannot be based on commitments to improve the performance of an asset in the future.
Where changes to an asset are made during a 3-year certification cycle:
- BREEAM In-Use V6 allows the asset's mid-cycle performance to be updated and reflected in an updated certificate.
- Legacy versions of BREEAM In-Use recognize updated performance via re-certification.
Renewal – Change in Asset Ownership and/or Management - KBCN1060
Before annual certificate renewal for Part 1 and 2 certificates, BRE Global requests confirmation from the client that no significant changes have been made to the asset or building management of the asset. Significant changes are those made to the asset or its management that result in a change in the overall rating of more than 5%.
Change in ownership
In a situation whereby the building owner changes whilst there is a valid BREEAM In-Use certificate, providing the new building owner sends BRE Global formal confirmation of ownership, and confirmation that they have not made any significant changes to the asset or building management of the asset since acquiring the asset, the certificate can be updated to reflect the new owner. Part 1 and 2 renewals can continue as per the standard process until the assessment is due for re-certification.
Change in building/property manager
In a situation whereby the building/property management changes whilst there is a valid BREEAM In-Use certificate, the process alters depending on the parts certified:
For Part 1 certification, renewals can continue as per the standard process until the assessment is due-for re-certification.
For Part 2 certification, the change in building/property management constitutes as a significant change. A Part 2 assessment is based on the procedures and policies in place in relation to the operation of the asset and consequently if this organisation changes, the evidence in place from the initial assessment will no longer represent the current situation.
For this reason, if the building/property management changes whilst there is a valid BREEAM In-Use Part 2 certificate, a full re-assessment including site visit is required.
Please note: BREEAM In-Use certificates display all Parts certified on one certificate, for this reason, if one or more parts requires full re-assessment all Parts need to be re-submitted.
Residential eligibility criteria – clarification on occupancy levels [superseded] - KBCN1523
01 Nov 2014 This guidance is now superseded. Please refer to KBCN1668
Resources inventory – Scope - KBCN1667
The inventory only needs to include resources that belong to the asset owner (or those which the asset owner or manger is responsible for maintaining or replacing). It does not need to included tenant-owned fittings and furnishings
Risk assessment – flooding is the only natural hazard - KBCN1552
Where:
- Flooding is the only natural hazard identified and,
- The flood risk assessment (FRA) from Rsl 01 is used as evidence for this issue,
then Answer D ('the asset is in an area where no risks exist') is only available where the FRA shows zero or low flood risk from
all sources of flooding.
Assessing flood risk from rivers and seas only does not cover all risks.
Safe pedestrian routes: definition, measurement and verification - KBCN0238
Definition
Safe pedestrian routes include sidewalks and safe crossing points, which may be controlled or, for example, be identified by tactile paving, a crossing island or a dropped curb. An element of judgement may be required, in which case justification should be provided.
Measurement
Distances could be measured, for example, along a sidewalk, across a road at a safe crossing point and along the sidewalk on the other side. The distance should not be measured diagonally across a road, following the most direct route.
Evidence from Google Maps or other digital sources may be used to indicate routes and distances, provided that the scale is appropriate and clearly indicated.
Verification
The assessor’s site inspection is an important aspect of the assessment of this issue as it must confirm that all relevant information is current and should include photographs of any key areas. This may also help to identify safe crossing points or hazards which may not be apparent from a desktop study.
For BREEAM NC and RFO assessments, Google Streetview may be acceptable as evidence to demonstrate safe pedestrian routes and the presence of key features or amenities at Design Stage only. Such information must be verified as above for Final Certification.
07 Mar 2024 - No changes have been made. This appears as 'updated' due to an administrative error.
11 Jan 2024 - Wording re-structured for clarity
19 Dec 2023 - Applicability to BIU V6 confirmed
Scope of the criteria for lifts – Small service lifts (dumbwaiters) - KBCN1589
Small service lifts, of the type typically used to transport prepared food and crockery in restaurants (sometimes referred to as 'dumbwaiters'), fall outside the scope of this assessment issue.
Shower with multiple shower heads - KBCN0855
To calculate the water use of a shower with more than one shower head, one of the following should be done:
- If all of the shower heads can be turned on at once, the flow rates should be added up.
- If the shower heads can only be used one at a time, the highest flow rate should be used
22 Feb 2024 - Applied to BIU, BREEAM NC and RFO standards
Single and Multiple Certification options - KBCN1430
BIU Residential provides flexible options to allow as many residential buildings as possible to be rated and receive a certificate. These include:
Apartments
- Multiple certificates, one for each individual apartment unit
- A single certificate for all the apartments only
- A single certificate for all the apartments and the common area
Houses
- Multiple certificates, one for each individual house unit
- A single certificate for all the houses
Benefits of the different certification options
Multiple certificates – These show the performance of each residential unit. This can show the difference in scoring and rating between units, which could be used for sales purposes or as a way of targeting specific units for improvements. When opting for multiple certificates, the rating of the best performing units will not be limited by the performance in other units.
Evidence must be collated from each building that is included in the assessment and where performance against the BREEAM requirements varies, the final score will be determined by the apartment or home with the lowest level of performance.
Single Certificates – These show the performance of the apartment(s) or house(s) as a whole. While performance has to be documented for each dwelling, BREEAM Projects includes features which help streamline this process.
Which certification route is right for my Asset?
When assessing just the Asset Performance in BREEAM In-Use Residential v6, the choice of certification option is up to the client. However, if Management Performance is included in the scope of assessment then the differing data requirements will determine which certification option the project needs to follow. These differing data requirements are driven by the energy consumption data available.
The flow diagram below can be used as a guide to determine the appropriate certification route for your project, given the energy consumption data available.
The scope of the energy data available will typically be more variable for an apartment building compared to houses. Houses tend to be individually metered, and therefore certification options are more open to client choice.
Note: Any asset without compliant consumption data will not be able to achieve all of the credits within Management Performance (e.g. the Operational Energy Calculator and Water)
If further assistance is required, please contact BRE at
[email protected]
24 Apr 2024 - Paragraph headed 'Benefits of the different certification options' updated for clarity and KBCN applied to BREEAM In-Use USA Residential
20 July 2021 Amended for clarification and flow diagram updated
Single tenant - KBCN1640
Where the assessment area is only occupied by a single tenant, the issue is not filtered out. All relevant credits apply.
The criteria is designed to recognise efforts between the asset owner and tenants to coordinate sustainability policies and resource monitoring. This principle is not affected by having a single tenant, even if they might act in the role of a managing occupier.
Smoking policy – External areas - KBCN1680
The criteria do not require that the asset provide a designated external smoking area.
The intent of Specific Note 1 is that the asset management encourage compliance with the no smoking policy by identifying areas where building users are not prohibited from smoking. However, where it is justified that no such areas can be identified within proximity of the asset, this requirement can be disregarded.
Sub-metering – Requirements for water-consuming plant/building areas or no additional monitoring benefit - KBCN1637
Significant water demand:
The following water uses are deemed to be significant:
- Swimming pools and their associated changing facilities (toilets, showers etc.)
- On sites with multiple units or buildings, e.g. shopping centres, apartment blocks, industrial units, retail parks etc. separate sub-meters are fitted on the water supply to the following areas (where present):
a. For Residential buildings with multiple dwellings and Residential Institutions with multiple with self-contained dwellings, each dwelling counts as a significant water use.
b. Common areas (e.g., covering the supply to toilet blocks).
c. Service areas (covering the supply to outlets within storage, delivery, waste disposal areas etc.).
d. Ancillary or separate buildings to the main development with a water supply.
- Laboratories: in any building with a laboratory (or containing laboratories), a separate water meter is fitted on the water supply to any process or cooling loop for plumbed-in laboratory process equipment.
All water consuming systems or building areas that are expected to account for more than 10% of the buildings total water demand must be considered when determining significant water uses.
No additional monitoring benefit:
Sub metering is not required where the project team confirms there will be no additional monitoring benefit resulting from their installation.
Examples include:
- Where a building has only one or two small sources of water demand (e.g. an office with only sanitary fittings and a small kitchen facilities).
- Where the building has two sources of water demand, one significantly larger than the other, and the water consumption for the larger demand is likely to mask the smaller demand (e.g. where there is a larger water demand from a changing area complete with showers and toilets, and the only other water demand is for toilet facilities).
Where the asset is targeting answer E (sub-metering) and:
- Can show that there is no additional monitoring benefit from installing sub-meters in line with criterion 5 and,
- Has met the requirements for answers C (site metering) and D (building metering),
then the 6 credits for answer E are awarded by default.
16 October 2024: Updated to include examples of water-consuming plant/building areas and also where no additional monitoring benefit.
Sub-metering requirements for a Single Tenant - KBCN1201
Where the asset has a single tenant, or where it is owner occupied, this space must have both heating and cooling sub-metered to achieve maximum credits.
Sub-metering technologies – Compliance principle - KBCN1561
Where it can be demonstrated that alternative sub-metering technologies can meet or exceed the capabilities of systems set out in the BREEAM guidance, subject to approval, these can also be considered compliant.
It is the role of the Assessor and the project team to provide evidence and justification in a compliance principle query (see
KBCN1555).
The following metering standards or technologies are currently recognized as alternatives to pulsed output meters:
- M-bus.
I.e. systems that comply with the EN 13757 series of standards.
Also includes systems complying with the OMS (Open Metering System) standards.
Suitability of waste storage facilities - KBCN0186
In situations where direct vehicular access to the recyclable waste store is limited by logistics or if size is a problem, for example inner city locations, some flexibility to the application of the criteria is allowed.
The assessor can use their judgement on whether the storage space is appropriately sized and if the distance and changes in level via lifts or steps are acceptable. Convenience, H&S issues and the volume and type of waste likely to be generated must be considered. Where the assessor deems the arrangement to be satisfactory this would be acceptable.
Typically, ‘accessible’ is defined as being within 66ft of a building entrance. In some circumstances site restrictions or tenancy arrangements could mean it is not possible for the facilities to be within 66ft of a building entrance. If, in the opinion of the BREEAM assessor it is not feasible for the facilities to be within 66ft of a building entrance, their judgement can be used to determine if the facility is deemed to be ‘accessible’ to the building occupants and for vehicle collection.
Systems serving <10% overall floor area - other affected issues - KBCN1542
The methodology for Ene 01 states:
"Heating / cooling systems can be excluded from the calculation where the heated or cooled area equates to less than 10% of overall floor area."
Systems which heat or cool < 10% overall floor area
are not assessed in:
- Ene 01 Building services.
- Ene 05 Cooling.
- Ene 06 Heating.
Ene 01, 05 and 06 all feed into the asset energy calculator and so their inputs must be consistent. All other issues relating to these excluded systems are still assessed such as:
- Ene 11 Installed controls.
- Ene 15 and 16 Monitoring energy issues.
- Pol 03 Local air quality.
- Pol 04 Global warming potential of refrigerants.
Technical: Location of scheme technical documents - KBCN00022
All scheme technical manuals are available to view and download on the BREEAM website.

Always refer to the BREEAM website to make sure that you have access to the most up-to-date version of the relevant scheme technical manual.
Using water from natural underground sources to offset water consumption - KBCN00094
Water from natural underground sources (for instance aquifer water accessed via boreholes) cannot be used to offset:
- NC / RFO: potable water consumption.
- IU: utility supplied water consumption.
A significant amount of water used for public consumption is already drawn from aquifers. Private boreholes may be drawing water from the same sources as public utility companies.
27-Mar-2024 - Title and text updated to broaden definition. Scheme applicability updated.
Validity of consumption data - KBCN1304
In order to maintain the reliability of data entered into the BREEAM In-Use Online Platform, any consumption-related data submitted must have a reporting period start date which is no more than one year prior to the start of the assessment (creation of a measurement).
For example, if the assessment was started on the 3rd of April 2018, the reporting period start date cannot be prior to 3rd of April 2017. A more recent period can always be entered, as long as the assessor can verify that the data is correct for the period entered.
Verification of consumption data - KBCN1019
Where consumption data has been entered into the Part 2 Energy Calculator, the Assessor must provide evidence to support it and demonstrate its correlation to the assessed area. The consumption figures shall be supported by either corresponding energy bills or verified meter readings (or a combination of the two). This means that, for example, simply submitting a spreadsheet containing consumption figures is not compliant and clear demonstration that this has been verified is required. Furthermore, it is also possible that the energy bills available to an asset might not coincide with the assessed area for the asset, in which case further evidence is required to demonstrate the actual consumption for the assessed area.
Since there are many different methods in which energy data can be monitored (e.g. manual meter readings, Energy Management Systems etc.), the format used when submitting meter readings often varies between assessments, leading to confusion for Assessors on whether particular evidence meets the requirements.
For these reasons, further clarity has been provided outlining how compliance can be met when neither energy bills nor verified meter readings (by the Assessor) are available for the assessed area. In these instances, it is possible to submit the following evidence to support consumption data figures:
- Clear description of how the consumption data was obtained, e.g. manual reading, automatic reading from a BMS, energy bills, etc.;
- Clear description of any calculation carried out, e.g. energy use determined by subtracting sub-metered data from main meter readings;
- Clear reporting of the period the consumption data relates to, i.e. start date and end-date for each consumption figure;
- Clear confirmation that the figures submitted refer to the consumption for the assessed area and that they are based on metered data, rather than estimations or apportionment. Such confirmation will be provided and signed from either someone internal to the organization or the Assessor themselves.
Where this is undertaken by someone other than the Assessor, the Assessor must be satisfied that the information is correct, and that the individual has a good understanding of metering systems and of the metering strategy of the particular asset being assessed. This should be clearly stated within the Assessor comments.
Verification of consumption data - KBCN1019
Where consumption data has been entered into the BREEAM In-Use Part 2 Energy Calculator, the Assessor must provide evidence to support this and demonstrate its correlation to the assessed area. The consumption figures shall be supported by either corresponding utility bills or verified metered consumption data (or a combination of the two). This means that, for example, simply submitting a spreadsheet containing consumption figures is not compliant, clear demonstration that this has been verified is required.
It is also common that available utility bills may not coincide with the assessed area for an asset, this means that further evidence is required to demonstrate the actual consumption for the assessed area.
Since there are many different methods in which energy data can be monitored (e.g. manual meter readings, Energy Management Systems etc.), the format used when submitting metered consumption data often varies between assessments. This often leads to confusion for Assessors on whether particular evidence meets the requirements.
For these reasons, further clarity has been provided outlining how compliance can be met when neither appropriate utility bills nor verified metered consumption data (undertaken by the Assessor) are available for the assessed area. In these instances, it is possible to
strengthen this existing evidence with a verification statement. Please see the following guidance below:
- Clear description of how the consumption data was obtained for each question, e.g. manual reading, automatic reading from a BMS, energy bills, etc.;
- Clear description of any calculations carried out to the data before it is entered into the BREEAM In-Use online platform, e.g. energy use determined by subtracting sub-metered data from main meter readings;
- Clear reporting of the period the consumption data relates to, i.e. start date and end-date for each consumption figure;
- Clear confirmation that the data covers the assessed area only, and is based on metered data, rather than estimations or apportionment.
- Such confirmation will be provided and signed from either someone internal to the organization or the Assessor themselves (see Note below).
Where confirmation is undertaken by someone other than the Assessor, the Assessor must be content that the information is correct, and that the individual has a good understanding of metering systems and of the metering strategy of the particular asset being assessed. This should be clearly outlined within the Assessor comments.
Note: BREEAM USA In-Use Version 6 includes a method that can be used where the asset does not have consumption data which covers the assessment area only. Please see Ene 19 in the relevant BREEAM USA In-Use Version 6 technical manual for more details.
View out – alternative method of compliance for fixed workstations - KBCN1484
In relevant spaces that include fixed workstations* (such as a built-in cash registers or reception desks) an alternative method can be used. This is based on the number of compliant workstations.
For instance, where the requirement is for 95% of the relevant area to comply, 95% of the fixed workstations must have a compliant view out, rounded up to the nearest workstation.
Example
A retail assessment has 35 built-in cash registers, 95% of which must comply with the view out criteria.
35 x 0.95 = 33.25, rounded up to 34.
The requirement is met for this area if 34 registers comply with the criteria.
Where an asset includes a mix of relevant areas; both fixed workstations and flexible areas, compliance for the whole assessment must be demonstrated for all areas as appropriate, based on either area or number.
*freestanding desks and other items of moveable furniture cannot be considered as fixed workstations, regardless of whether their locations are pre-determined.
View out – Calculating the glazing to wall ratio - KBCN1506
This should be calculated based on the glazed area of window, expressed as a percentage of the area of the external wall in which the window sits.
Where the ceiling height of the room is unusually high, relative to the window height, the wall area can be calculated based on a standard ceiling height for the building type.
View out – eye level - KBCN0581
BREEAM defines an adequate view out as being at seated eye level (1.2 – 1.3m) within the relevant building areas. However, where occupants will not have the option to be seated, for example in some industrial operational areas where the work being undertaken requires occupants to remain standing, the height of the view out can be changed accordingly to suit the eye level of occupants. All other view out requirements have to be met and clear justification provided for changing the height/level of the view out.
In some relevant building areas, occupants may not be sitting down to undertake tasks. Allowing the view out height requirements to be changed accordingly ensures building occupants gain maximum benefit from the view out.
View out – relevant areas - KBCN0268
The aim of the View Out criteria is to allow occupants to refocus their eyes from close work.
Relevant areas are spaces where close work in a fixed position is carried out for sustained periods of time.
The view out criteria are therefore not applicable to occupied areas such as meeting rooms, or other spaces where such close work is not being carried out.
Where rooms contain areas of different functions, only relevant areas should be assessed. In this case a notional line can be drawn on the plans and calculations made based on these relevant areas only.
However, spaces such circulation routes or other transient spaces within a relevant area can only be excluded if the route or area is clearly defined by the building layout. If this is arbitrary or based solely on a proposed furniture layout, it cannot be excluded. Features of the building layout which may be considered as dictating a function area would include, for example, the position of doors or fixed furniture such as a reception desk or canteen servery.
07-Oct-2022 Additional paragraph added to clarify how function areas must be defined.
21-Sep-2022 General principle of 'relevant area' added, and applicability of KBCN extended to BIU V6 Commercial.
Volume Approach – Site visit requirements - KBCN1644
This guidance applies only to assessments for clients who have entered into a formal agreement with BRE to enter the Volume Approach.
The aim of the Volume Approach is to assist clients with large numbers of assets, and their assessors, to conduct assessments in a robust manner, whilst also taking a practical view. From the clients’ assets that have entered the process, BRE will identify which assets may undertake a virtual site visit.
The assets and their assessments cannot be new to the BREEAM In-Use process and must be identified and communicated to BRE prior to undertaking the site visits.
The requirements of the virtual site visits are as follows:
Gathering evidence for site assessments:
In cases where BRE has identified an asset can undergo a virtual site visit, the assessor is not required to personally visit or gain access to the site, they can use the following methods:
- Appoint a suitable individual, for example a main contractor or asset manager, to undertake a formal site assessment on their behalf. The appointed individual would be expected to provide a robust account to the assessor of evidence in place of their own site assessment report. We would expect the report to contain photographs and/or virtual tour stills from the building and be signed off by both the appointed individual and assessor.
- For assessment issues relating to external spaces beyond the site, we will accept stills/images from Google Street View (or equivalent), provided it is demonstrated that such evidence is current.
- Desk-based evidence will be accepted where evidence demonstrates that the criteria are being met as far as possible without a site assessment.
It is important to note that where one of the above 3 options has been selected, the assessor is responsible for assessing the evidence and for the awarding of any credits.
Timing of workshops, testing and other subsidiary evidence submissions:
Given the widespread availability of remote communication technologies, it is generally possible to undertake the majority of activities relating to our assessment criteria without the need for face-to-face contact or site assessments. With respect to workshops, the key consideration is that they take place at a time when they have a meaningful impact and achieve the aim of the criteria.
With respect to subsidiary, third party assessments such as ecological site inspections or audits, desktop surveys based on available information (e.g. planning surveys, agent’s reports, photographs, Google Earth), can be used as an alternative provided there is enough material for a confident recommendation and/or outcome to be achieved.
Washer dryers - KBCN0699
Where a washer dryer is specified, the water consumption figure for the wash and dry cycle should be used.
The drying cycle of a washer dryer is taken into account because it usually uses water during this drying process (e.g. for cooling during the drying cycle) and in some cases, this water usage can be significant.
18-Nov-2022 - Updated to apply to BREEAM In-Use Version 6
Washing machines and dishwashers – Water consumption data - KBCN1571
The water consumption data used to demonstrate compliance may be based on the lowest full wash cycle (i.e. not a pre-wash cycle, for example).
Waste streams – clarification - KBCN1526
Scope
The focus of the criteria is on
recyclable materials only. Any facilities / spaces for managing recyclable materials must be
in addition to spaces / facilities for managing general waste.
Definition
“Waste streams are flows of specific waste, from its source through to recovery, recycling or disposal. Waste streams can be divided into two broad types:
- Streams made of materials (such as metals or plastics).
- Streams made of certain products (such as electronic waste or end-of-life vehicles).”
Source
For BREEAM, a waste stream is a material / product with its own recycling process. This means each stream needs to be separated from other materials before it can be effectively processed into new materials / products. This separation can happen in the asset, or (in the case of co-mingled waste) after collection from the asset.
Residential waste streams
In most cases, this is defined by how it will be how be sorted and collected by municipal waste authorities. Where no local guidance exists, the list below may be used as a guide.
Recyclable waste streams (answer option C in BREEAM USA In-Use Residential V6):
- Paper and cardboard.
- Glass.
- Plastics.
- Metals.
- Wood and wood-based products.
- Oils.
- Batteries.
- Electrical and electronic equipment.
Compostable / recyclable waste streams (answer option D in BREEAM USA In-Use Residential V6):
- Food waste.
- Garden waste.
Commercial waste streams
Commercial assets will generate specialised waste streams specific to the asset's function. These are typically:
- Generated consistently, and in large volumes.
- Are specifically separated for recycling.
In these cases, waste streams such as metals, plastics and paper / cardboard may be sub-divided into specialised waste streams where they meet the above.
Example scenarios
[accordion]
[accordion_block title="Scope"]
A vehicle repair workshop generates the following waste streams:
- Metals.
- Paper / cardboard.
- Plastics.
- Engine oils.
- General waste.
The engine oils and general waste cannot be re-processed into other usable materials. Only 3 recyclable waste streams can be considered for BREEAM assessment.
[/accordion_block]
[accordion_block title="Residential"]
The local authority collects co-mingled waste for the asset. This waste mixes together:
- Metals.
- Paper and cardboard.
- Plastics.
This co-mingled waste can be counted as 3 waste streams.
[/accordion_block]
[accordion_block title="Commercial"]
A supermarket consistently generates large quantities of cardboard packaging. This cardboard forms a significant portion of recycable waste generation. It is baled up and collected separately by a specialised waste contractor.
In this case, cardboard waste can be considered a separate waste stream from paper.

Water consumption reporting – Link to Man 04 - KBCN1611
The link to meeting compliance with Man 04, outlined in Wat 13 Criterion 1 is incorrect and should be disregarded.
Answer option D in Man 04 includes targets for Energy, Water and Waste. Whereas the intent of Wat 13 relates to targets for Water only. This will be updated in the next reissue of the technical manual.
Water strategy – Replacement and Schedule - KBCN1673
Replacement
The intent is that there is a programme in place which identifies any planned refurbishments and confirms that, where relevant, the works will include upgrading high water-consuming fittings and appliances with low water-consuming equivalents.
This does not require the systematic replacement of all fittings and appliances. However, it must also include a commitment to upgrading the efficiency of existing fittings and appliances when they reach the end of their service life.
Schedule
This may include specific fittings and appliances with low water consumption, or it can be based on a performance specification that these must meet, e.g. the flow rate or efficiency rating.
Watercourse pollution from indoor parking - KBCN0545
If the design team can demonstrate that there will be absolutely no run-off from the indoor parking then the intent of the credit will be met. However, such proof would also have to demonstrate that no hydrocarbon spillage from vehicles found its way into the watercourse/sewer. It is likely that there would be water ingress from outside or that internal parking areas would have drains fitted and be cleaned regularly. In such conditions, the criteria are still applicable.
The intent of this criteria is to ensure no hydrocarbons run off to any watercourse.
WELL building standard – alignment with BREEAM - KBCN0737
Assessing health and wellbeing in buildings - Alignment between BREEAM and the WELL building standard
BRE and the International WELL Building Institute™ (IWBI™) are collaborating to promote health and wellbeing in the design, construction and operation of buildings and fit-outs, internationally. The two organisations announced their collaboration on 28 November 2016 with the aim to make it more efficient for clients and project teams to pursue both of their respective standards: BREEAM and the WELL Building StandardTM (WELL).
To simplify the process for project teams pursuing both assessment methods, BRE and IWBI have worked together to compare performance requirements, harmonise evidence and identify opportunities to streamline the process of achieving dual certification. This work demonstrates the significant synergies between the two methods and the efficiencies that exist between their respective assessment and certification processes. It forms a part of an ongoing collaboration between BRE and IWBI to work together to harmonise their approach to health and wellbeing in the built environment across their standards, research programmes and services generally.

Zoning and occupant control – access to lighting controls - KBCN00032
The relevant areas for the criteria apply only to areas where users are expected to have control.
For instance, this means that areas intended for the general public, or a shop floor would not be expected to have lighting controls.
The general principle which applies to user access to general environmental controls (heating, cooling, ventilation) may also apply to access to lighting controls. See
KBCN0170.
However, the the exact approach may differ between the two types of systems and assessor judgement must be used to determine compliance.
In all cases zoning is required in all areas of the asset where specified in the assessment criteria. Please refer to the specific requirements of the applicable BREEAM standard to interpret this guidance appropriately.
14-Dec-2022 - KBCN applicability updated to include BIU. Wording updated. Link to KBCN0170 created.
Zoning and occupant control – PIR detection systems - KBCN0335
The aim of the Health & Wellbeing category is to recognize ways to benefit occupants through giving them control of their lighting environment. Without manual overrides, presence or absence detection lighting controls (such as PIR detection systems) are not compliant with the criteria.
BREEAM recognises the energy efficiency benefits of detection systems in buildings through the Energy category. In some cases, the design team may have to prioritize one particular lighting strategy to the detriment of achieving a credit elsewhere.
Zoning and occupant control – whiteboards and display screens - KBCN1433
Whiteboards and display screens in dedicated teaching or presentation spaces require separate zoning and control for lighting, as specified in the criteria.
Lighting around whiteboards and display screens which are typically found in general office areas, meeting rooms, or in other generic spaces do not require separate zoning and control to meet the criteria. In such cases, the assessor should provide justification.
Whiteboards and display screens in dedicated teaching / presentation spaces are likely to be used frequently, and require appropriate zoning and control. An increasing number of offices and meeting rooms now include display screens - however separate zoning and control may not be appropriate.
Information correct as of 27thDecember 2024. Please see kb.breeam.com for the latest compliance information.
