Approved Equivalent Roles List (AERL) - KBCN1809

BREEAM International standards are unique because of their flexibility. For International projects, Assessors can submit roles to substitute those described in the Technical Manuals. Provided that such roles are equivalent to the BREEAM specified roles, BRE Global will approve them for use in a particular country or region. The Approved Equivalent Roles List is a record of all roles that BRE Global has approved to date. The list is periodically updated to reflect recent approvals or withdrawals. Using existing approved roles Where you are using an approved role, and not the role described in the criteria in the scheme Technical Manuals, a copy of the AERL should be included as part of your evidence submission for QA. AERL versions The version of the AERL that is current at the time of registration is the one that is used for assessment. Newer versions released after this can also be used, however older versions before the registration date cannot be used. For example: if the version current at registration was v3.0, then v3.0 (or any later versions) can be used, but v2.0 (or any earlier versions) cannot be used. Proposing new roles New roles cannot be proposed if they are not of equal competency to the BREEAM requirements. Only roles which are equivalent or more rigorous than the BREEAM default roles are considered. If you wish to propose a new role which you think is equivalent in your country or region:

Check what the role needs to cover by referring to the roles described in the scheme Technical Manual definition.
Complete BF2599 BREEAM Approved Equivalent Roles Application Form and send this to our Technical Team via the Query Webform, adding AERL into the subject field.

The information provided to us within this form must include:

the names of the proposed role(s)
confirmation of the scheme and issues the role should apply to
confirmation of the roles / competent persons you are referring to in the manual
a detailed explanation of how this work is conducted in your market and how it meets the same level of competency as the BREEAM requirements
documentation to support your explanation which is clearly marked for our ease of reference. If the documentation is not in English, translations of the relevant sections must be provided.

We will need a few weeks to review the information (please check with us for time scales). If there is missing information, or the information is not clearly referenced, this might take longer. If successful, we will send you a revised copy of the AERL which includes the new role, and will update this for future versions of the AERL.

Assessment of multiple buildings within a single BREEAM assessment - KBCN1836

Ene01, Ene02 and Wat01, which use area-weighted performance scales, must be assessed using the methodology set out below where multiple buildings are included within the scope of a single BREEAM assessment, including where: • the Similar Buildings approach is applied, in accordance with Section 4 of GN20; or • Separate buildings with a single overarching function are located on the same site, in accordance with Section 6 of GN20 (e.g. a principal building with one or more ancillary or supporting buildings). Ene01 For UK NC projects, energy models (BRUKL files) must be uploaded for each building included within the assessment. For International NC projects, the assessor must enter floor area-weighted average values for the relevant energy performance metrics for both the actual building(s) and the reference building(s), covering all buildings and applicable building uses included in the assessment. Ene02 All buildings included within the assessment must be modelled in accordance with the methodology. The energy performance score must be calculated using floor area-weighted metrics covering all buildings, and compared against a benchmark derived from a floor area weighted average of all building types included within the assessment. Wat01 For Wat01, the assessor must enter details for all water-using components across all buildings included within the assessment. The Wat01 benchmark is determined using a floor area-weighted occupancy by building type, covering all buildings within scope of the BREEAM assessment.

ASWL Process update - KBCN1756

Formerly known as the ASWL for V6 and 2016, this has been renamed as Approved Standards List (ASL) for V7. It follows a similar Excel format to the International New Construction ASWL for V6 and 2016 versions. The V7 ASL document has been updated to align with the International New Construction V7 manual. In Version 7, we’ve introduced several updates to improve the approved standards and weightings process:

Pre-populated country sheets and weightings are now available for countries where most assessments have previously taken place. This will make it easier and quicker for assessors to begin assessments in those countries.

The process has been streamlined by integrating the ‘Detailed Checks on Standards’ sheet directly into each individual country sheet.

The ASL process remains consistent with that used in Version 6.

The V7 weightings form (used for generating weightings in new countries) has been updated with new, relevant questions to align with the International New Construction Version 7 manual. However, the overall weightings process remains the same as for Version 6 and 2016.

Looking ahead, we plan to transition the ASL process to an online format. Further details will be shared in upcoming assessor updates.

Bamboo, cork and other non-timber forest products – Responsible sourcing - KBCN1768

Non-timber forest products, such as bamboo and cork should be responsibly sourced to minimise the environmental impacts and protect local ecosystems. However, as they are not timber or timber-based products, these fall outside the scope of the Prerequisite. Where such products are integrated into a building, they should, nonetheless, be assessed and included in the calculator under ‘Other materials’.

BREEAM Excel Tools - KBCN1755

The new BREEAM Platform now integrates all Excel-based calculator tools directly into the system for a more streamlined experience. Simply input your data, and the platform will automatically calculate and display the results. Please note, this functionality currently applies only to BREEAM New Construction V7.

BREEAM New Construction V7 – FAQs - KBCN1754

The FAQ webpage has been developed to provide early clarification and guidance on aspects of BREEAM New Construction Version 7 (NC V7). It is intended to address questions and highlight key changes from previous versions. Further guidance is provided within the published technical manual, and this will be supplemented by Knowledge Base Compliance Notes (KBCNs). To see the full list of FAQs, please refer to the Version 7 FAQs webpage

Capped gas supplies – Shell & core assessments - KBCN1818

If a capped-off gas supply is provided, this does not prevent credits from being awarded under criterion 1. The key requirement is that all heating and hot water systems designed or installed within the scope of works (the core services) must use non-combustion systems.

Clarification of ‘Embodied carbon benchmark comparison’ - KBCN1819

The embodied carbon benchmark comparison must always be based on the latest appropriate LCA stage that corresponds to the BREEAM assessment stage being pursued. The purpose of the benchmark comparison is to assess outcome-based embodied carbon performance, using data that is representative of the building at the relevant assessment stage.

Assessment stage requirements

Interim (Design Stage) BREEAM assessments

Where an interim / design stage assessment is being submitted:
- The benchmark comparison may be based on a Technical Design LCA, where this represents the latest LCA available at that stage.
- Benchmark results at this stage are indicative and intended to support design decision-making.

Final Post-Construction Stage (PCS) BREEAM assessments

Where a final post-construction stage (PCS) assessment is being submitted:
- Benchmark comparison credits can only be awarded where a Post-Construction Stage (PCS) LCA has been completed.
- A technical design LCA alone is not sufficient to support benchmark comparison credits at PCS.
- This is because the PCS LCA is the only assessment that reflects the materials and products actually installed in the completed building, and therefore the only suitable basis for outcome-based benchmarking.

If a PCS LCA is not undertaken, benchmark comparison credits cannot be awarded at final assessment, regardless of whether a technical design LCA was previously completed. This aligns with wider industry frameworks (e.g. RICS WLCA v2 and the UK Net Zero Carbon Buildings Standard), which anchor performance claims to as-built outcomes.

Daylight – Shading devices - KBCN1815

If any of the assessed spaces are expected to contain moveable shading device (such as blinds), then a dynamic modelling of their use should be included in the calculation for options 2 and 3, consideration should be made to the shading guidance in EN 17037 or IES LM-83-23, respectively. Option 1 does not have to include dynamic modelling of moveable shading devices. This will be updated in the next re-issue of the new construction version 7 schemes.

Emissions from products – specialist paints and coatings - KBCN0872

Where a paint or coating falls within:

A category in Annex II of the EU Directive 2004/42/CE or,
A category in the relevant product emission table of the technical manual,

then the paint or coating must be assessed. Specialist paints and coatings are exempted from meeting the VOC content and emission limits where there are no alternative products available that can perform the function, and still meet the emission limits. This must be clearly evidenced.

02-Oct-2025 Reference to 'VOC content' added and KBCN applied to INC V7 to clarify CN2.1
27-Oct-2022 Wording clarified. New compliance principle added from UKNC V6.
10-Oct-2022 Title amended for clarity. Scheme applicability updated.
13-Mar-2020 KBCN amended to clarify exceptions and applicability.
16-Jun-2017 Content merged with KBCN0212.

ERRATUM – Scope – Mixed-use developments and building types - KBCN1820

The wording and approach set out for assessing mixed-use developments in the technical manual is incorrect. Developments comprising of separate buildings with different function types cannot be assessed under a single assessment, unless they meet the conditions for Section 6 of GN20 (Separate buildings with a single, over-arching function). The updated guidance can be found below: Mixed-use developments and building types BREEAM defines different criteria and benchmarks for some assessment issues according to building type, function and use. A single building that includes different functions areas, e.g. office and retail, can be assessed under a single BREEAM assessment. Each area will need to comply with the relevant criteria for the building type. BREEAM credits that are awarded based on performance scales, such as Ene 01, Ene 02, Wat 01 and Mat 01, will be calculated on an area weighted basis. Buildings that are a mix of commercial and residential asset types, and developments which comprise of separate buildings with different function types, will need separate BREEAM assessments. Further guidance can be found in Guidance Note 20.

Glare control – Modelling - KBCN1800

The ‘Glare control’ criteria do not require a specific methodology to be used to identify areas at risk of glare, and in most situations, a simple solar path analysis would be suitable. Alternatively, detailed hourly modelling methods, such as DGP and ASE, may be more appropriate. However, in either case, compliance cannot be assumed. Regardless of the methodology used, the modelling must be supported by robust reporting to demonstrate that each aspect of the criteria has been met.

GN20 Assessing mixed-use and multiple buildings – BREEAM V7 - KBCN0717

Latest version: v1.0, January 2026 Guidance Note 20 (GN20) provides information to help BREEAM Assessors formulate an assessment strategy for mixed-use developments, assets that include different levels of fit out, and for multiple buildings or units on the same site using BREEAM V7.

GN22 Recognised schemes for emissions from construction products - KBCN0719

Latest version: v3.1, March 2026 Within the Health and Wellbeing category of several BREEAM schemes, credits are awarded for specifying materials that minimise emissions from building products of formaldehyde and volatile organic compounds (VOCs). The criteria involve meeting emission level performance requirements in accordance with compliant performance and testing standards. Guidance Note 22 (GN22) lists schemes that show equivalent or better performance than the current BREEAM and HQM criteria, and therefore can be used to demonstrate compliance with the criteria. This document should be read in conjunction with the relevant assessment issue guidance provided in the appropriate BREEAM or HQM technical manual. The guidance note contains two tables:

Table 1 is for use with BREEAM schemes that were first released before December 2015.
Table 2 is for use with BREEAM (and HQM) schemes that were first released from December 2015 onwards (post-November 2015).

Download Guidance Note 22 View all Guidance Notes on BREEAM Projects (licensed assessors only) Applying for inclusion in GN22 The list of approved schemes is based on those which have made a successful application to BREEAM. As such, there may be other operational schemes that could potentially be recognised. To be considered for inclusion, the scheme operator must complete an application form, providing full details of the scheme, and submit this to BRE Global for technical approval. A flat rate charge is payable to cover the costs of administering and reviewing the application. GN22 will be updated following the approval of any schemes via this process.

GN49 International Ene 01 calculation methodology guidance - KBCN1749

Latest version: v0.0, July 2025 Guidance Note 49 (GN49) gives background information on the methodology for determining the number of credits achieved for energy performance under the Ene 01 assessment issue for BREEAM International NC V7. The Ene 01 methodology uses a triple metric approach that addresses energy demand for heating and cooling, primary energy consumption, and carbon dioxide emissions. The aim of using this approach is to minimise the energy consumption and carbon emissions from regulated energy uses and to maximise the use of low carbon energy sources. Guidance Note 49 also includes the adjustment factors that are applied to uplift the reference metrics in Ene 01 for BREEAM International NC V7. It describes the methodology for determining the factors and the application process to have a country’s adjustment factor added or updated.

Knowledge Base – Applicability of existing guidance to NC V7 - KBCN1757

We are in the process of undertaking a comprehensive review of existing guidance on the Knowledge Base for BREEAM New Construction to determine its applicability to New Construction Version 7, and the Knowledge Base will be updated in due course. In the meantime, if you wish to apply for a previous KBCN, please review the changes outlined in the Summary of Changes and compare the criteria in the technical manuals. If the criteria are the same, and you are satisfied that a previous New Construction KBCN is relevant to NC V7, you can follow this guidance. If there are differences in the New Construction V7 criteria, but you believe an existing KBCN can be applied, please submit a technical query on the webform to confirm this.

Legally harvested and traded timber – Examples - KBCN0956

Life Cycle Assessment for multiple buildings within a single assessment (GN20 – Section 6) - KBCN1835

Where a BREEAM assessment includes multiple buildings on the same site with a single, over-arching function, in accordance with Section 6 of GN20 (e.g. a principal building with one or more ancillary or supporting buildings), and where these are not classified as ‘similar buildings’, each building must be assessed and reported separately within the LCA. A single aggregated result for the whole site is not sufficient on its own, even where a single coordinated LCA model is used. Shared elements (e.g. substructure, external works, or building services serving multiple buildings) may be apportioned between buildings using a reasonable and transparent method (e.g. by gross internal area or other appropriate project-specific metric), in line with recognised industry approaches. For the purposes of BREEAM benchmarking under Mat 01: • The results submitted to the platform must represent a single building, not a combined site-wide result. • Where multiple buildings are included within an assessment, benchmarking (in kgCO₂e/m²) must be based on the principal building. Where no clear principal building exists, the largest building should be used. Full evidence must be provided to demonstrate: • That all buildings within scope are included, with individual LCAs completed for each building, and • How results have been separated and, where relevant, how shared elements have been allocated.

Rationale: Industry standards such as RICS guidance and the UK Net Zero Carbon Buildings Standard define assessment boundaries at the building (asset) level, while allowing aggregation at project level only where individual building results are also reported. Requiring building-level results ensures consistency with industry practice, maintains comparability with BREEAM benchmarks, and avoids distortion where multiple buildings are combined into a single result.

Note: This approach applies until further platform functionality is available to support multi-building submissions directly.

Life Cycle Assessment where similar buildings approach is being followed (GN20 – Section 4) - KBCN1834

Where multiple buildings are included within the scope of a single BREEAM assessment following the Similar Buildings approach, in accordance with Section 4 of GN20, unless identical, each building must be assessed and reported separately within the LCA. Shared elements (e.g. substructure, external works, or building services serving multiple buildings) may be apportioned between buildings using a reasonable and transparent method (e.g. by gross internal area or other appropriate project-specific metric), in line with recognised industry approaches. For the purposes of BREEAM benchmarking under Mat 01: • The results submitted to the platform must represent a single building, not a combined site-wide result. • Where multiple buildings are included within an assessment, the worst-performing building (in kgCO₂e/m²) must be used for benchmarking in line with the Similar Buildings methodology (section 4.2 of GN20). Full evidence must be provided to demonstrate: • That all buildings within scope of the assessment have been included, with individual LCAs completed for each building, and • How results have been separated and, where relevant, how shared elements have been allocated.

Rationale: In line with Section 4.2 of GN20, BREEAM issues must be assessed for each individual building, with credits awarded based on the worst‑performing building for each assessment issue. The Similar Buildings approach therefore remains an individual‑building assessment methodology and does not constitute a site‑wide assessment, even where multiple buildings are included.

Meeting the minimum standard requirement – compliance when chain of custody is broken - KBCN1816

Where there is a broken chain in the last link between the purchase and delivery of certified timber from the supplier and the forwarding distribution of the timber to the site under assessment, such as where the timber has been delivered to a subcontractor or fabricator’s premises instead of direct to site (e.g. as part of a bulk order or where limited storage is available on site), compliance can still be achieved if a documented risk assessment confirms that there is low risk of mixing or substitution of certified and non-certified timber. Ways to demonstrate compliance: A. Verification that the subcontractor or fabricator only purchases and uses certified timber. There must be robust mechanisms in place to verify that all timber materials purchased and delivered originate from sustainably managed sources. This includes maintaining documented timber procurement policies and procedures that mandate certified timber orders and delivery checks. Comprehensive supplier details should be readily accessible for review upon request to demonstrate that all timber is certified. B. Where non-certified timber is handled/stored or sourced, that there are robust control measures in place to prevent any substitution or mixing of certified and non-certified timber at every stage of the process. Documentation demonstrating compliance should be maintained and made available upon request. Examples of appropriate control measures are listed below:

Control	Evidence required
Purchasing records	All purchase orders, requisition notes, and contracts must explicitly specify the product details and confirm that materials are to originate from legal and sustainable sources.
Segregated storage of timber	Site layout map, stock control processes and records to confirm that certified timber is stored away from non-certified timber.
Segregated delivery of timber to site	- All timber must be thoroughly inspected and verified before shipment to confirm that it is correctly marked/labelled as FSC/PEFC-certified. - Delivery notes must be accurately maintained. - A second-party verification process to check tickets and stock, must be carried out upon site delivery to confirm certified status of timber.
Documentation	Comprehensive documentation must enable independent assessors to trace any timber back to its sustainable source. This includes maintaining purchase records, goods-inward notices, stock records, and sales documentation such as orders and invoices.

The above is guidance and should not replace any local or national requirements for the sourcing of legally traded and harvested timber.

Predicted operational energy performance score – Credit table update - KBCN1825

From 4^th February 2026, the following credit table applies to Ene 02 in all BREEAM International New Construction V7 and BREEAM UK New Construction V7 assessments:

^{*Alternatively meet the minimum EPR_NC score specified for Excellent in Ene 01.} ^{**Alternatively meet the minimum EPR_NC score specified for Outstanding in Ene 01.} The OEP_NC scores required for each credit boundary have been lowered on the BREEAM platform in response to assessor feedback and an internal review of credit attainment against our benchmark database. The table above supersedes: - Table 28 in BREEAM International New Construction V7 - Table 6.3 in BREEAM UK New Construction V7 For further guidance on Ene 02 and the achievement of OEP_NC scores please refer to KBCN1751 - GN53 Energy modelling and predicted operational energy performance score in Ene 02. The above updated credit table will be included in the next reissue of the technical manuals

Verification of Security Needs Assessments/Security Risk Assessments - KBCN1770

Where the author of a Security Needs Assessment [‘Security Risk Assessment’ in BIU] does not meet the BREEAM competency requirements, compliance can still be achieved where the report is reviewed and verified by a qualified SQSS [‘Competent Person’ in BIU], who confirms in writing that it is accurate, appropriate and in line with industry best practice. In these circumstances, the SQSS or ‘Competent Person’ is expected to verify and take ownership of the report and accept professional responsibility for its content.

View out – communal lounges, living rooms and bedrooms - KBCN1828

The default criteria for these space types requires relevant positions to be within 5m of an opening. Where larger spaces are ≥ 50m2 NIA, the standard view out criteria for the relevant scheme is applied instead. The 5m rule is intended for small scale domestic spaces where proximity to a view out is beneficial. This KBCN recognises that for larger relevant spaces in Residential, Multi-Residential and Residential Institution asset types, a scalable approach in line with commercial buildings is more appropriate.
