BREEAM Accredited Professional (AP) – Retrospectively applying AP status - KBCN0308
The AP status cannot be applied retrospectively. The purpose of using an AP on a project is that they can advise and steer the development from the outset to maximise its BREEAM and sustainability performance for the least cost/risk. If early AP appointment and involvement does not occur then the aims and criteria of this BREEAM issue are not being met.
BREEAM AP – Achieving the design credit at the Post Construction Assessment - KBCN0215
Where a project will be undertaking a post construction stage assessment only (no interim assessment), to demonstrate that the criteria were met at the design stage a "BREEAM credit monitoring report" should be provided when the assessment is submitted, which shows that at the design stage of the project the building was still on target for the proposed BREEAM rating. This could be an excel document showing the issues that the design is on target for achieving with a short summary of how the BREEAM AP is steering the project for the correct rating.
As long as the criteria are met and the correct information can be gathered for your evidence, a design stage certification is not required.
BREEAM AP – Change of BREEAM APs/Sustainability champions during project - KBCN0295
Whilst it would generally be preferable to retain the same individual in the role of BREEAM AP/Sustainability champion throughout the design and construction of a particular project for the purposes of continuity, we appreciate that this may not always be feasible. It is therefore entirely appropriate that the three credits available for using BREEAM APs/Sustainability champions can still be awarded where the individual performing the role changes (provided the ongoing involvement of an AP/SC is maintained in accordance with the criteria).
BREEAM AP and BREEAM assessor – conflict of interest - KBCN0196
An individual can be appointed as a BREEAM/HQM Assessor and BREEAM AP/Sustainability Champion for the same project (assuming that the individual is qualified in both of these roles). If this route is chosen, it must be made clear when submitting the assessment that both roles are being carried out by the same person and confirmed how potential conflicts of interest are identified and managed. This will mean, when appropriate, that the assessment can be escalated to a more detailed level of quality assurance checking.
BREEAM AP/Sustainability champion appointment timing - KBCN0419
It is acceptable for a BREEAM AP to be appointed in the early stages of RIBA Stage C/ RIBA Stage 2, if it can be demonstrated that the AP was appointed at the earliest appropriate time in the project and that the late involvement will not have a detrimental effect on the setting of BREEAM performance targets that need to be formally agreed no later than RIBA Stage 2.
Change in main contractor - KBCN0645
In situations where the main contractor changes mid-project, for example where the original contractor goes into administration and is replaced by another main contractor, it is acceptable for the post-construction credits to be awarded based on the new contractor providing information on their activities. This is providing the project is yet to start on site. This is in effect assessing the issue using the Post Construction Assessment route instead of a Post Construction Review.
However, if the project has already started on site and information about the site activities of the previous contractor is not available it would not be appropriate to award the credit solely based on the new contractor activities.
Changes to CCS scoring system – January 2019 - KBCN1271
In January 2019, the Considerate Constructors' Scheme (CCS) modified its scoring system, so that innovations are more easily recognised and rewarded. To view the CCS announcement and a summary of the changes, please follow this link
This change does not impact on the established score thresholds, for awarding credits in relevant BREEAM Schemes.
Commissioning – Fume cupboards approved standards - KBCN0111
The following standards have been approved and can be used to demonstrate compliance with the commissioning credit for fume cupboards:
- BS 7989:2001
- CLEAPPS G9 Fume Cupboards in Schools - Revision of DfEE Building Bulletin 88
- BS EN 14175-4
Commissioning – Monitor and specialist commissioning manager - KBCN00051
The commissioning monitor is typically a project team member who will monitor the systems commissioning and testing programme for the building. The individual may combine that role with that of the specialist commissioning manager to deal with complex systems if they have the necessary knowledge. However, if the building has several specialist systems it is unlikely that the same person would be able to carry out all of the commissioning and more than one specialist would most likely be required.
Commissioning – Role of Specialist commissioning manager - KBCN0604
The specialist commissioning manager for a complex system must be a specialist contractor and not a general sub-contractor. They must be on hand to independently verify the work carried out by whomever installs the system.
In principle, it is possible for the specialist commissioning manager to be from the same organisation as the main contractor provided any conflicts of interest have been declared and records show how they have been managed to provide confidence that commissioning will be carried out appropriately.
The separate roles of the main contractor and specialist commissioning manager are so that the installation and commissioning are carried out independently by different parties.
Considerate construction – corporate registration - KBCN0905
Where credits are awarded for the assessment of the site against a compliant scheme, corporate registration, which assesses the contractor's overall operations and performance across multiple sites, is not in itself recognised.
To award considerate construction credits, BREEAM requires the assessment of the specific assessed development, in line with the criteria.
Considerate Constructors Scheme – Phased developments - KBCN0328
The Considerate Constructors Scheme does make provision for phased developments within the registration process, allowing each phase to be registered separately. They make this provision to allow for very large developments that may go on over several years. It should therefore be possible for the developer to register the site in phases, so that CCS certificates can be submitted for BREEAM assessed buildings, without having to wait for the completion of the final phase.
Definition – Critical value - KBCN1006
Critical value aims to maximise whole life value
of the building based on client requirements, and differs from minimising life cycle cost. This is a more specific analysis of how the building's ongoing maintenance and operation can impact business needs. For instance:
- Where any disruption to business is costly, a specification with long periods between maintenance cycles and reduced maintenance time may be desirable.
- Where maintaining aesthetics are important, a maintenance cycle may be based on aesthetic upkeep rather than functional lifespan.
- Where maximum recyclability and re-usability is important, an alternative, costlier specification may be required.
- Where capital costs are constrained, the specification with the lowest LCC may not be affordable, and instead, the best available option within the budget is chosen.
Definition – Project value - KBCN0552
The term ‘project value’ represents the total project cost, which includes all costs such as construction, design, land acquisition etc.
Design team meetings via conference call - KBCN0201
Design team meetings can be conducted via conference calls.
It can be difficult for design team members to be in the same place at the same time. Conference calls are a more sustainable way to conduct meetings.
Environmental Checklist section 2.2.5 - KBCN0225
In May 2013 the Environment Agency updated their guidance document "Building A Better Environment" and Checklist 2.2.5 is no longer included. However, the EA have allowed the continued use of Checklist 2.2.5 from the original 2006 guidance for the purposes of demonstrating compliance with Man 03.
It can be found on the extranet:

Environmental management – no principal contractor - KBCN1213
In order to achieve compliance where there is no principal contractor, the criteria must be met by the party which fulfills an equivalent role in managing the construction.
The intent of the criteria is to ensure that the site is managed in accordance with demonstrably sustainable principles by the party having overall control of site management and operations.
Environmental management – Timing of obtaining ISO 14001/EMAS certification - KBCN0229
The contractor must be in possession of the ISO 14001/EMAS certification prior to starting works on the development under assessment.
This is to ensure that the aim of the issue, to ‘encourage construction sites managed in an environmentally sound manner’, can be achieved. To uphold the robustness of BREEAM, the date of certification to ISO 14001/EMAS must be prior to initial works starting on the site.
FSC Controlled Wood - KBCN00054
FSC Controlled Wood is a system developed to ensure that the non-certified portion in products labelled as Mixed Sources do not come from unwanted sources. It is not an FSC certification on its own and products classed as FSC Controlled Wood do not meet the BREEAM definition of responsibly sourced.
GN05 Considerate Constructors Scheme and the BREEAM schemes - KBCN0617
This guidance note applies to all BREEAM UK versions and schemes including New Construction, Domestic Refurbishment and EcoHomes. Up and coming changes to the Considerate Constructors Scheme (CCS) will have an impact on the performance levels required under all schemes and versions of BREEAM, EcoHomes1 and BREEAM Domestic Refurbishment2 i.e. issue Man 02. This guidance note outlines the changes to the CCS and how this will affect BREEAM assessments

Inclusive and accessible design – TAN 12 in Wales - KBCN0324
For buildings in Wales, ‘TAN 12: Design' can be used to support the design of the building so that it is inclusive and accessible. However, the document 'Design & Access Statements in Wales - Why, what and how' (referenced within TAN 12) will need to be used in addition to TAN 12 in place of the CABE publication as this gives specific guidance for writing the access statement itself.
Independent party - KBCN00058
The client/design team carrying out the consultation/post-occupancy evaluation can demonstrate compliance with the requirement for an independent third party in two ways:
1) An independent third party, not involved in the design or development of the building, has conducted the necessary consultation exercise using a compliant method.
2) If the evaluation is carried out by an organisation involved in the design of the building, evidence demonstrating the party's independence of the design process must be provided. The design team or relevant individual must demonstrate a credible level of independence to meet the requirement.
Legally harvested and traded/Legal and sustainable timber – Reclaimed/recycled timber - KBCN0654
Timber should, wherever possible, be sourced in accordance with the UK Government’s Timber Procurement Policy. However, if for reclaimed timber the original procurement details are unobtainable, robust evidence to demonstrate it has been reclaimed can be acceptable.
The government UK Government Timber Procurement Policy Timber Procurement Advice Note (6th edition) states:
As an alternative to demanding timber and wood-derived products from a Legal and Sustainable source, Contracting Authorities can demand ‘recycled timber’. Documentary evidence and independent verification will also apply to recycled timber and recycled wood-derived products but will focus on the use to which the timber was previously put rather than the forest source.
And defines ‘recycled timber’ as:
“…recovered wood that prior to being supplied to the Contracting Authority had an end use as a standalone object or as part of a structure and which has completed its lifecycle and would otherwise be disposed of as waste. The term ‘recycled’ is used to cover the following categories: pre-consumer recycled wood and wood fibre or industrial by products but excluding sawmill co-products (sawmill co-products are deemed to fall within the category of virgin timber), post-consumer recycled wood and wood fibre, and drift wood. It also covers reclaimed timber which was abandoned or confiscated at least ten years previously.”
As per the above policy, BREEAM requires “Documentary evidence and independent verification” that all reclaimed/recycled timber products meet the definition of ‘recycled timber’ given above.
01/06/2020: Amended to clarify and extended applicability to Mat 03
Life Cycle Cost - KBCN0385
Life Cycle Costing (LCC) is a methodology that aims at selecting the optimal option amongst a number of option appraisals.
An LCC should therefore consider at least two design option appraisals and should be based on more than one cash flow scenario in order to provide systematic economic evaluation of life cycle costs over a period of analysis.
Life cycle cost (LCC)- QS change - KBCN0605
If a Quantity Surveyor (QS) changes during a project, the new QS must demonstrate that subsequent criteria are met in order to gain the 2nd and 3rd credits. While the initial modelling data may not be available, the results and outputs given to the client team will be and can be used to remodel the LCC at the later stages of development using the new QS's data. Provided the new QS can model and determine the best option based on the latest project information, the 2nd and 3rd credits can still be attained.
It may be necessary to repeat modelling where there has been a change of QS however, provided the intent of the issue and criteria are met, the credits can still be awarded.
Life cycle cost – Multiple assessments on the same site - KBCN000003
Where there are multiple assessments on a site and a single life cycle cost (LCC) plan will be carried out, it is acceptable to use this plan as evidence provided that the results of the LCC plan can be applied to all of the assessed buildings and therefore may have a positive influence on the material specification of such buildings. Where the design of some assessments differ to the extent that the LCC plan cannot reasonably be applied, a separate LCC plan is necessary to achieve credits for this issue.
Where multiple assessments are covered under a single LCC plan, there must be sufficient detail for each building to enable them to be adequately assessed.
Pollution Prevention Guidance documents - KBCN1051
On 17 December 2015, the Pollution Prevention Guidance documents (PPGs) published by the Environment Agency were withdrawn. These can be found in the National Archives or on the Scottish Environment Protection Agency website where they are still current documents.
Many BREEAM schemes and the Home Quality Mark refer to these PPG documents as they are still considered to be best practice even though they have been withdrawn. Projects should continue to use the PPGs referenced in the relevant manuals.
BREEAM will continue to review this situation and provide an update as and when appropriate.
26 09 2018 Made applicable to Man 03 and Pol 03 in UK NC2018 and Man 03 in UK NC 2011, UK NC2014 and UKRFO 2014
Post Occupancy Evaluation – Bespoke - KBCN0678
It is acceptable to use a bespoke POE providing that the assessor is satisfied that the methodology covers all relevant aspects of a compliant POE. The assessor should therefore refer to the further guidance on POE provided in the BREEAM technical manual for information on what a compliant POE methodology should contain, as copied below:
- The BCO guide to Post Occupancy Evaluation (POE), British Council for Offices, 2007
- BRE Digest 478, Building performance feedback: getting started, Building Research Establishment, 2003
- Guide to Post Occupancy Evaluation Report and Toolkit, HEFCE, AUDE & University of Westminster, 2006
Responsible construction practices – Multiple contractors on the same project - KBCN0352
It is the site that must comply with BREEAM issues rather than any individual contractor. Several different contractors may have obligations to meet compliance criteria. One of the contractors and/or site managers may have responsibility for ensuring compliance during site operations. It is ultimately the client/project team's responsibility to determine and demonstrate compliance.
Scope of construction works included - KBCN0642
Only the scope of works the principal contractor is responsible for needs to be considered in the assessment of this Issue. This also includes works carried out by sub-contractors that are engaged by the principal contractor.
Seasonal commissioning evidence - KBCN0818
Where the criteria require that seasonal commissioning activities are to be completed over a minimum 12 month period following the occupation of the building, it is accepted that completed records may not be available at the time of Final Certification.
In such cases, evidence of the appointment of a seasonal commissioning manager and schedule of commissioning responsibilities which fulfils the BREEAM criteria are acceptable to demonstrate compliance.
Seasonal commissioning of Solar Photovoltaics (PV) - KBCN0244
Solar PVs can be excluded from the requirements for seasonal commissioning. This is because commissioning at a particular time of the year will not affect the original commissioning of the system.
Stakeholder consultation – Building occupier unknown - KBCN0227
Where the building occupier is unknown, it is still possible to achieve the credit. The end user requirements must be assumed and considered by other project parties (e.g. client, design team, etc.) using their experience and judgement until such time as the occupier is known.
Stakeholder consultation – Definition of “independent third party” - KBCN0428
The definition of independent third party should be taken to mean that the party i.e. the individual(s) rather than the organisation undertaking the consultation is independent of the design process. BREEAM is not prescriptive about how to evidence this. It is the assessor's responsibility to collect robust evidence which proves this to be the case.
Stakeholder consultation – Existing shared facilities - KBCN0360
The consultation must include any existing shared facilities relied on to achieve compliance as well as the new facilities.
To ensure the shared existing facilities are appropriate and in line with the users' requirements.
Submitting aftercare & post occupancy evaluation data - KBCN0589
Where credits have been awarded which require post-occupancy evaluation or an element of aftercare data collection (according to scheme requirements) from the building once operational and occupied, the data gathering must take place at the specified time and the findings reported to BRE.
The timing of this evidence gathering depends on the criteria of the BREEAM scheme having been undertaken. However, for all schemes, once the evidence is due for submission, it should be sent to BREEAM@bre.co.uk with the following title;
'BREEAM Assessment Type
Building Data BREEAM Assessment Reference
For example, a BREEAM 2011 New Construction assessment would use the following title when submitting their evidence;
'BREEAM NC 2011 Building Data BREEAM-1234-5678'
This KBCN replaces KBCN0695 for HQM.
Testing and inspecting building fabric – Untreated spaces - KBCN0972
Untreated spaces, which are not subject to compliance with statutory energy performance regulations, can be excluded from the scope of the 'Testing and inspecting building fabric/thermographic survey/air pressure testing' criteria.
Thermographic survey – Seasonal constraints - KBCN00031
Where seasonal constraints prevent the thermographic survey from being completed prior to certification at the post construction stage, the requirements can be satisfied with:
Thermographic surveys are designed to map the thermal efficiency of buildings and to detect areas where there are breaches in the thermal envelope. Surveys need to be conducted when temperature differences between the external areas of the building and surrounding air can be detected after the envelope is sealed. There may will be instances where the survey cannot be done before certification after the envelope is sealed and as such, the survey would take place after certification.
- Evidence that a Suitably Qualified Professional (SQP) has been contractually appointed
- Written confirmation by the SQP that the seasonal constraints prevent the survey at an appropriate time before certification
- The survey is scheduled to take place at the earliest opportunity after the handover, and
- There is a specific contractual agreement in place to remedy any identified defects before the defects liability period expires.
Thermographic survey – Shell & Core - KBCN0198
Generally it is most appropriate to carry out a thermographic survey once the thermal envelope is complete and the building services have been installed. Where this is not the case, an appropriate professional should be consulted to confirm a suitable way forward for individual projects at the shell and core stage. Subject to the paragraph below, if it is not possible to undertake a full and accurate survey at this stage, the credit must be withheld.
Imposing the requirement for a thermographic survey on an unknown future tenant by using a green lease agreement or green building guide is not acceptable as it may be difficult and unreasonable to expect the tenant to remediate any defects revealed by the survey. If the future tenant is known and there is a robust arrangement and contractually binding agreement in place to undertake a thermographic survey and remedy any defects, Shell & Core Option 3 may be used, subject to the submission of appropriate evidence.
Thermographic survey – suitable standards - KBCN0689
Assessors can accept reports from thermographers who hold a suitable Infrared Thermographic Testing (TT) qualification under one of the following standards, depending on which one was current at the time of the thermographer's qualification:
- ISO 18436-7:2008
- ISO 9712:2012
- ISO 18436-7:2014
- ISO 6781-3:2015
13/03/2017: Compliance note amended to allow the applicability of standards based on the time of the thermographer's qualification, rather than the BREEAM scheme version.
Thermographic survey and report – Qualifications - KBCN0322
The UKTA (UK Thermography Association) defines what is currently accepted as a suitable qualification for building thermography in line with ISO 18436-7 (Building or Civil), PCN CM/GEN Appendix B Civil and ISO 6781-3
As of 6th June 2014, the PCN (Civil) Level 2 and ABBE Level 4 Building Thermographer qualifications are recognised by the UKTA as suitable for BREEAM thermographic surveys. Work is underway to align these requirements with other qualification routes and these will be reviewed by the UKTA on a case by case basis. For more information, please contact the UKTA directly via www.ukta.org
It is acceptable for the survey to be undertaken by other appropriately qualified building thermography professionals provided the analysis and report is undertaken or overseen, quality checked and signed by an appropriately qualified professional as defined by the UKTA.
Thermographic survey for large and complex buildings - KBCN0405
In the case of large and complex buildings, it may be impractical for the thermographic survey and air-tightness testing to cover 100% of the building. The level of the survey should be decided by a Level 2 qualified thermographic surveyor. This could include, for example, airports, large hospitals and high-rise buildings.
Information correct as of 2ndMarch 2021. Please see kb.breeam.com for the latest compliance information.
Transport of construction materials – Data and methodology - KBCN0413
To ensure comparability across assessments, the information completed in the scoring and reporting tool should be restricted to the minimum data specified in the technical manual.
For the purposes of this BREEAM Issue, the distances reported should be calculated from the point from which the products or materials were sourced, whether this be directly from a manufacturer or from a builders' merchant/distributor:
- For products or materials purchased directly from a manufacturer or quarry, for example, the distance should be calculated from the ‘factory gate’, including any intermediate transport.
- For products or materials, which are purchased from a merchant or distributor, only the distance from their depot should be reported.
Where products cannot be sourced locally, for example on small islands, the transport required to import the materials or products can be discounted, and only the local onward transport to the site recorded.
The aim of this requirement is to encourage developers to consider the impacts of transporting products and materials to site. As such, the criteria seek to address only those impacts, which can be influenced by the developer.
27.07.2018 Wording amended to add clarity.
