Adaptation to climate change strategy study – timing - KBCN0533

Late consideration of the climate change adaptation strategy study, might reduce the study to a ‘paper exercise’, with minimal value to the project. However, if the assessor is satisfied that there is clear justification for the strategy being developed at a slightly later stage (i.e. early RIBA stage 3) AND there is clear evidence that the strategy has achieved the intended outcomes (i.e. the later consideration has been in no way detrimental to the outcomes of the strategy study/appraisal and the benefits can still be realised on the project), then this will be sufficient for compliance. In any case, all other requirements of the issue must be met for the credits to be awarded. The requirements for the timing of the climate change adaptation strategy are intended to ensure that the benefits of these strategies are realised through early consideration.

Alternatives to composting - KBCN0465

In anaerobic digesters, organic waste is digested by micro-organisms which break down fats, oils and grease. Digesters where the only output is water that is safe to discharge into drains and sewers are acceptable alternatives to composting. Macerators which simply reduce solids into small pieces through a shredding or grinding process and flush the residue into the drainage system are not an acceptable alternative to composting.

Apportioning foundations where not all floors are assessed - KBCN0643

Where a development does not include all the storeys of a building, not all of the aggregates used in the building foundations need to be included in the assessment.  Any apportioning must be justified and calculated by a structural engineer, and it is the responsibility of the assessor to ensure that the process used is appropriate, robust and meets the aim of the credit issue.

Considering Sand and Cement Replacements - KBCN0181

Neither sand or cement replacements should be taken into account when assessing the percentage of recycled or secondary aggregate used in a project. The recycled aggregates issue only assesses the use of coarse aggregates.  
29/03/2017 Title amended and additional reference to cement substitutes added
 

Contractor not yet appointed at the design stage - KBCN000002

Where the contractor has not been engaged at the design stage certification, it is acceptable to award the credits based on a commitment. This commitment must be from a suitable member of the design team, and must detail the targets and criteria which must be met. Evidence must also confirm that the details in the commitment will form part of the contractual requirements. Note: This does not apply to the requirement for a pre-demolition/pre-refurbishment audit, which must be undertaken at Concept Design Stage.
12 Jul 2022 - Note added to clarify the scope of this guidance
 

Contractual agreements for Shell Only / Shell & Core assessments - KBCN0942

For Shell Only and Shell & Core (RFO Part 1, Part 2, and combined Part 1 & 2) assessments, all relevant criteria are applicable. Contractual agreements confirming future provision of spaces are not acceptable. Evidence must be provided showing waste storage space(s) that are suitably sized, dedicated and unlikely to be used by the future tenants for other purposes. While the location of the space/spaces may change when fitting out, at this stage a space that is conveniently located for the deposit and collection of operational waste must be provided.

Dedicated off-site manufacturing and fabrication - KBCN0794

Waste from 'dedicated off-site manufacturing or fabrication' should only be accounted for if the manufacturing process has been specifically developed for the project under assessment, excluding waste from manufacturing 'off the shelf' products. The assessment of waste should only consider the waste that has been specifically generated by the activities of the project under assessment.
24/02/2017 Applicability to Man 03 referred to in KBCN0795.

Demolition – external guidelines (incl BS 6187) - KBCN0630

Independent standards exist and some are referenced in the BREEAM manual and can be used to provide additional guidance for clients/design teams. Unless explicitly stated they are not 'deemed to satisfy' BREEAM criteria and assessors must demonstrate that BREEAM criteria have been met in the usual way. One such standard is BS 6187:2011 which gives good practice recommendations for the demolition (both full and partial) of facilities, including buildings and structures. The standard is therefore applicable to demolition activities undertaken as part of structural refurbishment. It also covers decommissioning. Unless explicitly stated external standards do not automatically satisfy BREEAM criteria and assessors must demonstrate that BREEAM criteria have been met in the usual way. 

Demolition records not available - KBCN1009

Where demolition records are missing, either wholly or in part, the credit available for diversion of construction and demolition waste from landfill cannot be achieved. This includes instances where demolition was conducted under a separate contract or by a third party on behalf of the developer.

Designed-out or integrated finishes - KBCN1066

The requirements for this credit are met when either: This issue recognises avoiding unnecessary waste of materials.
16-May-2023 - Merged with KBCN0046. Scheme applicability updated. Name updated for clarity.
 

Excluding applications from assessment - KBCN0875

Where a structural engineer has determined that recycled or secondary aggregate cannot be used in line with the criteria for a particular application, or where they will not allow the minimum BREEAM level to be used, that application can be excluded from the assessment. Where the engineer allows some content to be used, this percentage must still be specified in the excluded application. The engineer's decision must be suitably justified (for example following the BS8500 series and associated standards) and must be provided as evidence for the BREEAM assessment.

Existing materials recycled on site - KBCN0813

When existing elements are recycled (ie crushed and used as aggregate) on site, they can contribute to awarding credits as recycled aggregates. This issue aims to recognise and encourage the use of recycled and secondary aggregates and addresses waste rather than materials. It refers to recycled aggregate obtained on-site or off-site, based on materials identified as waste and removed during construction works. 
Previous incorrect KBCN text amended. CN 'Aggregates in existing applications' to be amended accordingly in next reissue of the RFO Technical manuals.

External works – waste reporting requirements - KBCN1379

Waste arising from external works does not need to be included within the calculations for construction resource efficiency. To do so would be incongruous with reporting waste relative to the building's floor area. This follows the logic of excluding excavation waste from this criterion. However, waste from external works should be addressed in the RMP and should also be reported in the calculations for the Diversion of resources from landfill credit, which is not reported relative to the building's floor area.

First fit-out of a shell only/shell and core development - KBCN00099

For assessments of a first fit-out of a new building the 'pre-refurbishment audit' credit is filtered out from the assessment.
03.11.2021 Issue 2.0 of the UK RFO technical manual amended.

Functional adaptation strategy study – content - KBCN0930

To achieve compliance with Wst 06, the building-specific functional adaptation strategy study should consider all the items listed in the relevant compliance note 'Functional adaptation strategy study'. Due to site specific constraints, it may not always be possible to pursue all of the items listed. In these cases, any omissions must be clearly justified in writing when submitting as evidence.

Functional adaptation strategy study – timing - KBCN0730

Late consideration of the strategy appraisal, might reduce the study to a ‘paper exercise’, with minimal value to the project. However, where the assessor is satisfied that there is clear justification for the study being developed at a slightly later stage (i.e. early RIBA stage 3) AND there is clear evidence that the strategy has achieved the intended outcomes (i.e. the later consideration has been in no way detrimental to the outcomes of the strategy study/appraisal and the benefits can still be realised on the project), this will be sufficient for compliance. In any case, all other requirements of the issue must be met for the credit to be awarded. The requirements for the timing of the functional adaptation strategy study are intended to ensure that the benefits of the study are realised through early consideration.

Granular fill and capping - KBCN1378

Granular fill and capping only refers to roadworks and not building foundations.

Home composting – Multi-residential - KBCN1004

The requirement to provide home composting facilities and an information leaflet applies to both multi-residential developments with only self-contained units and those with individual bedrooms and communal facilities.

Home composting facilities – clarification - KBCN0927

Home composting facilities are individual composting containers placed within the kitchen area or communal space for each self-contained dwelling, bedsit or communal kitchen. These containers are either emptied into local on-site communal facilities or are collected by composting collection services run by the waste collection authority. Individual composting containers should be:
  1. Located in a dedicated, non-obstructive position.
  2. Easily accessible to all users.
  3. Durable, low maintenance and cleanable.
  4. Enclosed to manage odour and pest issues.

Multi-Residential: Internal recyclable waste container if waste is sorted off site - KBCN0354

Where the Local Authority or waste management company for the scheme provide evidence confirming that recyclable waste will be sorted after they have collected it from site, it is acceptable to provide one internal storage bin of a minimum capacity of 30 L rather than 3 separate internal bins. The relevant recycling scheme must collect at least 3 of the following materials; paper, cardboard, glass, plastics, metals or textiles.    

Multi-residential: Waste storage shared by more than six bedrooms - KBCN0856

Where multi-residential buildings contain communal facilities shared by more than six bedrooms, the requirement for total waste storage can be increased on a pro-rata basis to demonstrate compliance. For instance, if the standard requirement is 30L for six bedrooms, this equates to 5L per bedroom. Where assessing a flat with eight bedrooms, this requirement increases to 40L (8 x 5L). The minimum size of individual containers remains unchanged as per the criteria.

Multiple developments monitoring construction waste on a site - KBCN00036

Where the same contractor is working on a site with more than one development, a single Site Waste Management Plan (SWMP)/Resource Management Plan (RMP) can be produced to demonstrate compliance, if it can be justified that separation of the waste would be impractical. Where the developments are of a similar nature, such as all new-build or all refurbishment with similar scope, the results from the whole development can be apportioned on the basis of floor area to derive the figures upon which the separate developments will be assessed. Where the buildings are not similar, the design team will need to provide calculations to demonstrate that the waste has been apportioned as accurately as possible according to the project types.
21/11/16 Clarification added in relation to dissimilar projects on the same site.

No high grade aggregates used on project - KBCN00098

Where no high grade aggregates will be used in a refurbishment scheme project, this credit is not applicable and will be filtered out of the assessment. This CN supersedes CN 'Aggregates in existing applications', currently on the technical manual, as its applicability to the RFO schemes has been reviewed. The CN was developed for the New Construction schemes to account for situations where, for example, existing foundations are re-used in-situ, thus avoiding the need for new high grade aggregates. In the RFO scheme, existing structural elements are generally retained, therefore it would not be appropriate to account for the aggregate within these.
25/10/2016 Clarification on the N/A of current CN 'Aggregates in existing applications' added.
03/11/2021 Issue 2.0 of the UK RFO technical manual has been amended.

Off-site waste sorting - KBCN0696

All schemes Where a building's recyclable waste is collected regularly and sorted off-site, the aim of this issue can be met by: This means providing evidence for all of the following:
  1. A waste management plan which provides on-site storage between collections, adequately sized based on the frequency of collection.
  2. An on-going waste recycling contract.
  3. The typical recycling rates from the waste management company.
  4. 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.
BIU only This KBCN applies to off-site sorting for construction waste arising from fit-out activities (Answer E, BIU V6, Rsc 02). It does not apply to the storage of reusable construction products (Answer F, BIU V6, Rsc 02). This must be a permanent structure or space currently in the asset. BREEAM assesses the sustainability of the intrinsic asset. Where robust management practices may be accepted as an alternative, BREEAM still requires that the asset's facilities have the potential for future conversion to achieve compliance.
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.

Operational waste – Additional requirements for multi-residential buildings with individual bedrooms and communal facilities only - KBCN1519

These criteria are intended for situations where occupants of individual rooms have access to shared kitchens, which can be used to prepare food, regardless of whether central catering is also available. In developments where all catering is managed centrally and no communal/shared kitchens are provided, these requirements do not apply. If, for example, catering is managed centrally, but there are small satellite kitchens for staff to sort/reheat food for residents, the assessor must justify whether and to what extent recyclable waste will be generated in these kitchens and demonstrate that adequate recyclable waste storage provided as appropriate.

Operational waste requirement for catering – applicability - KBCN1162

The additional operational waste storage requirement for developments which include catering is generally only applicable where a commercial scale kitchen is present. Where the design team can justify that there will be no significant waste streams from a modest facility, such as a small cafe, selling only drinks and pre-prepared snacks, the additional waste storage area identified in the default values does not need to be provided to meet compliance.

Operational waste storage sizing - KBCN0560

The dedicated space requirements given in the technical manual are default guidance, for situations where it is not possible to demonstrate the required size based on known waste streams. Compliance can, therefore, be achieved provided that it is clearly demonstrated and evidenced that there is adequate justification for the type of facilities & size of waste storage provided, and that the assessor is satisfied that the sizes and facilities meet the criteria based on the building type, occupancy and the likely waste volumes generated as a result of these.

Part 2 and/or 3 assessment; floors and ceilings not affected by works - KBCN0682

For a Part 2 and/or 3 only assessment (i.e. Parts 1 and 4 do not form part of the assessment), where it can be shown that there are to be no changes or minimal reinstatement of the floor, ceiling and interior finishes, the credit can be awarded.

Pre-demolition audit requirement - KBCN0243

Where the site demolition/clearance does not form part of the principal contractor’s works, but has been undertaken by the developer for the purposes of enabling the assessed development, a pre-demolition audit must be carried out and referenced within the SWMP as per the guidance. Where justification and robust evidence can be provided, the following exceptions may apply: This requirement seeks to encourage good practice by developers and design teams in relation to previously developed sites.
28.03.2022 Reference to pre-refurbishment audit removed, and separate KBCN1504 drafted for pre-refurbishment audit exemptions.
11.12.2019 Additional exception added to align with KBCN1257 and guidance re-structured for clarity
22.11.2017 Reference added to the pre-refurbishment audit for RFO assessments.
15.11.2017 Wording amended for clarity

Pre-demolition audit/(pre-refurbishment) on other structures and hard surfaces - KBCN00045

A pre-demolition/(pre-refurbishment) audit is required where any existing buildings, structures or hard surfaces are present on a development site. The intent of the pre-demolition/(pre-refurbishment) audit is to ensure that any potentially useful materials are considered for re-use or diversion from landfill, not just materials resulting from buildings. 
22.11.17 Reference added to the pre-refurbishment audit for RFO assessments.

Pre-refurbishment audit – definition of ‘competent person’ - KBCN0756

For the purposes of Wst 01, criterion 1b, a ‘competent person’ for the pre-refurbishment audit is someone who has knowledge of the value and condition of materials and what can or cannot be repaired. Although the ‘relevant definition’ is missing, it is effectively provided later in the sentence as someone who ‘has appropriate knowledge of buildings, waste and options for the reuse and recycling of different waste streams.’ A demolition contractor would be ideal for the role, but could also be the main contractor. To clarify, the 'competent person' does not have to be independent of the project.
11.09.2017 - Clarification on the removal of the independence requirement added. This takes precedence over the technical manual, which will
be updated accordingly in next reissue.
03.11.2021 Issue 2.0 of the UK RFO technical manual updated.
 

Pre-refurbishment audit – minimal or no demolition/strip-out - KBCN1504

Where there is no demolition or strip-out whatsoever within the assessment scope, the credit may be awarded without a pre-refurbishment audit - for example, in the fit-out of a new-build shell. This follows the logic that where zero waste is being generated, the intent of the criteria is met. In such cases, robust evidence must be provided that a pre-refurbishment audit cannot be carried out. However, where there is even minimal demolition or strip-out within the scope of the assessment, a pre-refurbishment audit must still be undertaken. This audit should be in proportion to the scale and extent of these works.

Pre-refurbishment/demolition audit – late development - KBCN0537

Where the pre-refurbishment/demolition audit has not been done at RIBA stage 2/Concept Design, as required in the criteria, the credit can still be achieved. Robust evidence must be provided confirming that the timing of the pre-refurbishment/demolition audit has not compromised its ability to influence the design, consideration of materials re-use and the setting of targets for waste management. Evidence must demonstrate that this allowed decisions to be made before the start of strip-out/demolition works.
26.07.2018 Applicability of KBCN extended to include the UKNC2018 scheme.

Re-use and direct recycling of materials - KBCN0894

The ‘Re-use and direct recycling of materials’ criteria always apply, even where there is nothing being taken out of the building, i.e. there is no strip-out. This means that waste from the actual refurbishment works, i.e. the new products being installed, which may potentially be recycled or re-used, such as damaged products, off-cuts, spares, pallets, packaging - anything delivered to the site, can contribute to the requirements for these credits. The ‘Re-use and direct recycling of materials’ criteria apply, regardless of whether the ‘Pre-refurbishment audit’ credit is applicable.

Re-use and direct recycling of materials – partial compliance - KBCN0803

In the current scheme, the points available in Table 65 for each waste material type can be achieved by a project which meets the re-use or direct recycling criteria for any proportion of that waste material type. Design teams should be incentivised to maximise the amount of re-used or recycled material, even if 100% of a material category cannot be re-used or recycled.

Recyclable, general and organic waste storage – space, labelling and segregation - KBCN1577

Strategies may vary according to the specifics of each project, their waste streams and collection arrangements. The aim of these requirements is to encourage recycling, ensuring that it is correctly sorted and to prevent cross-contamination of waste streams. Label the recycling area This is required to alert building users and collection agencies to the location of the recycling facility. Label each recyclable waste stream This can be done by labelling the bins or their dedicated space within the recycling facility, or both. Mixed recycling bins and / or spaces are clearly labelled with their constituent waste streams. General or organic waste have their own dedicated spaces Sufficient space for general and, where relevant, organic waste is required in addition to meeting the requirements for recyclable waste. This does not have to be within a separate facility, but if combined with recyclable waste storage, there is greater risk of cross-contamination. The following requirements apply in this situation: If provision of waste bins is out of scope Where the provision of waste bins is outside the scope of the developer, it is clearly not possible to label the bins. In this situation, the following compliance options are available:
21-May-2024 - Link to KBCN0696 removed. Merged with KBCN1380. Minor clarification added on mixed recycling.

Recycled aggregate evidence prior to contractor’s appointment - KBCN0231

If the contractor has not been appointed at the time of submitting the Design Stage assessment, whilst it is imperative for the design team to demonstrate a firm commitment to meet the criteria and award the credit at this stage, a letter from the design team or developer to confirm that no contractor has been appointed should be submitted in lieu of the stated letter of confirmation. This should also be clarified in the Assessment Report. BREEAM recognises that it may not be desirable to confirm the specification, source and availability of a particular recycled aggregate for a project where the contractor has not been appointed yet. This would restrict the contractor's ability to source the most economically viable recycled aggregate to meet the BREEAM criteria.

Recycled aggregates requirements - KBCN0343

The amount of recycled and/or secondary aggregate must be greater than 25% of the total amount of high-grade aggregate specified for the development. In order for the recycled/ secondary aggregate in each high-grade application to be included in the calculation of the 25% amount, the minimum percentages in the relevant table must first be met. Note: not all high-grade applications must meet the percentages in the table in order to award a credit, however all high-grade aggregate must be included in the total.   The following example is taking figures from UK NC 2014. The applications and percentages vary with each scheme version. If only Structural Frame, Building foundations and Granular fill/capping are present. The following calculation would be carried out to confirm compliance:

Structural Frame = 50 tonnes of aggregate; of which 5 tonnes is recycled/ secondary aggregate

Building foundations = 50 tonnes of aggregate; of which 8 tonnes is recycled/ secondary aggregate

Granular fill/capping = 80 tonnes of aggregate; of which 80 tonnes is recycled/ secondary aggregate

  Table 54 minimum percentages are:

Structural Frame must have 15% recycled/ secondary aggregate for 1 credit, i.e. at least 15% of 50 = 7.5 tonnes. In our example we have 5 tonnes, therefore this amount cannot be included in the total calculation, and all 50 tonnes must be considered as primary aggregate.

Building foundations must have 20% recycled/ secondary aggregate for 1 credit, i.e. at least 10 tonnes. We have 8 tonnes, so again, this must all be considered as primary aggregate.

Granular fill/capping must have 100% recycled/ secondary aggregate for 1 credit. In our example all 80 tonnes is, therefore this amount can be considered as recycled/ secondary aggregate.

  To determine if a credit can be awarded, the following calculation is then carried out:

Total aggregate; 50 + 50 + 80 = 180 tonnes Aggregate to be included in calculating % = 80 tonnes (Granular fill/capping only) % therefore is 80/180 = 44% which exceeds the 25% minimum

This shows that despite two high-grade applications not meeting the minimum threshold percentages, the overall % is sufficient to award the credit. The same principle applies to the calculation of the Exemplary level criteria.

Reporting information from SMARTWaste - KBCN0918

The majority of the information required for Wst 01 issue can be collected and reported in SMARTWaste, even though BREEAM UK RFO 2014 is not listed as an option for projects in SMARTWaste. The only item that isn’t covered is the methodology for calculating credits for reuse and direct recycling of materials (criteria 3 and 4). In addition to that, any calculations of credits shown for criteria 6 and 7 will not be correct for BREEAM UK RFO 2014. In that case, the credits should be awarded based on the information within the UKRFO technical manual. With regard to the evidence for BREEAM, assessors can use the information collected and reported in SMARTWaste if pdfs and reports provide this information. BREEAM UK RFO 2014 is included in the SMARTWaste development plan and further information will be provided in due course.      

Self-contained dwellings / bedrooms with shared facilities – mixed recycling - KBCN1664

Where there is mixed recycling, the number of recyclables containers can be reduced to match the final waste streams being collected. For example, the standard BREEAM requirement is three recyclables containers per dwelling / communal facility. The total combined storage volume requirements are the same as stated in the manuals. To apply this KBCN, the project team must provide evidence to QA of the waste collection policies that apply to the asset.

Solid concrete washout - KBCN00063

Solid concrete washout waste should be included in the waste resource efficiency benchmarks.  

Speculative office including floor finishes/suspended ceiling - KBCN0259

The requirements can still be met where a speculative development includes the installation of floor finishes/suspended ceilings provided a Lease Agreement will be implemented to confirm that tenants are not permitted to remove these finishes. BREEAM recognises that incoming tenants may need to adapt ceiling or floor finishes to suit the requirements of their fit-out. Therefore, where these finishes are installed throughout, in line with Criterion 2, the following applies: A tenancy agreement, applied to the first tenancy, should stipulate that floor or ceiling finishes may only be modified where necessary, for example, to accommodate new partitions, lighting or other services, to replace worn or damaged components or to replace small, localised areas with a specialist floor or ceiling to account for abnormal conditions, such as wet areas. Documentary evidence of this must be provided as evidence for the credit to be awarded.
18/04/2017 KBCN made applicable to NC 2016 and IRFO 2015  
05/07/2018 Paragraph added to clarify the requirements of the tenancy agreement
27 Jul 2021 Clarified that the terms of paragraph 2 apply also to floor finishes

Strip-out works - KBCN0578

Waste generated by strip-out works should be excluded from the Resource Efficiency credits, because the project cannot control the amount of waste that will be produced from strip-out works.  

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 20m of a building entrance. In some circumstances site restrictions or tenancy arrangements could mean it is not possible for the facilities to be within 20m of a building entrance. If, in the opinion of the BREEAM assessor it is not feasible for the facilities to be within 20m 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.

Using BRE SMARTWaste tool - KBCN0236

BRE SMARTWaste may be helpful in demonstrating the construction waste benchmarks; however its use is not compulsory to achieve the credits. Reference to the SMARTWaste tool has been included in the issue as an example of a tool that can be used to manage and monitor waste generated during construction.  

Waste management practices - KBCN0247

16/04/2018 This compliance note is no longer valid as it does not fully explain how to approach this Issue. Please refer to the technical guidance and other compliance notes, such as KBCN0696, which deals with co-mingled recyclable waste. The requirement to provide a dedicated space for the segregation and storage of operational recyclable waste, as well as relevant facilities (e.g. for large amounts of packaging and/or compostible waste), relates to the building, not the occupier or the local authorities. A dedicated space and facilities must be provided irrespective of the waste management practices of the relevant stakeholders. The BREEAM certification relates to the building, not the occupier's or the local authorities' waste management practices. Therefore, the provision of a dedicated space and the relevant facilities is required to ensure the building's operational recyclable waste streams is diverted from landfill.
22/02/2017 Amended to include facilities (in addition to dedicated spaces)

Waste storage provision for catering - KBCN0755

As the manual states, the additional 2m2 per 1000 m2 of waste storage area provided for catering is measured against the "net floor area where catering is provided" and NOT the floor area of the catering facility. Generally, a catering facility will serve building users throughout the building. If it can be demonstrated that this is not the case, for example if part of the development is subject to a separate tenancy, not served by the catering facility, the area calculation can be adjusted accordingly. Where the net floor area is not indicative of the actual occupancy, the default values may not be appropriate. In such cases, the predicted waste streams should be calculated based on the actual occupancy and waste streams generated. This requirement accounts for the increase in waste produced by building based on the likely number of building users served by the catering facility. Please note that these default calculations are only intended for use where it is not possible to determine accurately what provision should be made based on predicted waste streams. 
15 06 2017 Wording updated to clarify

[KBCN withdrawn] ~ No floor or ceiling finishes fitted - KBCN00046

Where the developer has not specified or installed any floor or ceiling finishes, the requirements are met. This issue recognises where the potential for generating unnecessary waste of materials has been avoided. 
16-May-2023 - Merged with KBCN1066. Withdrawn.
20-Dec-2017 - KBCN wording simplified to add clarity.
 

[Withdrawn] Labelling and signage – Where provision of waste bins is out of scope - KBCN1380

[This KBCN has been merged with KBCN1577]. Where the provision of waste bins is outside the scope of the developer, it is clearly not possible to label the bins. In this situation, the following compliance options are available:
  1. Provide compliant signage to the storage area and label bin spaces within the storage area according to the relevant waste streams.
  2. Where future waste streams are unknown, provide compliant signage to the storage area and a written commitment from the developer to ensure that the bins and/or bin spaces are labelled.
See also KBCN1577 It is recognised that the bins may be provided by the tenant, local authority or waste management company after the time of certification.
21-May-2024 - Withdrawn. Merged with KBCN1577.
22-Mar-2023 - Updated to align with KBCN1577 and to clarify applicability to all assessment types where providing bins is out of scope.

Information correct as of 23rdJuly 2024. Please see kb.breeam.com for the latest compliance information.
