Asset classification – co-living developments - KBCN1568

The following is a guide only. Every co-living project will combine a varying mix of residential with managed spaces, 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 facilities such as spaces for leisure, co-working spaces and common grounds.

Classification

• For NC or RFO, generally the most appropriate asset classification is 'Residential institutions - long term stay.'
• For BIU, it is generally Residential.

Using building regulation classifications as a guide As a guide, assessors can also consider how their asset is classified according to local regulations. For UK NC assets, KBCN1225 provides additional clarification:

• Projects classified under UK building regulations as Part L Volume 1: Dwellings (Previously Part L1) is considered residential and covered under HQM.
• Projects classified as Part L Volume 2: Buildings other than dwellings (Previously Part L2) is considered a residential institution.

Evidence – Photographs not permitted for security reasons - KBCN0389

Where photographs are not permitted during a 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.

Fit-out level – Selecting the appropriate assessment type - KBCN1627

Projects designed and constructed as fully fitted should not be evaluated as ‘Shell and core’ or ‘Shell-only’ where the intent is to limit the scope of the BREEAM assessment without further justification. Where the fit-out level of a project is not consistent, the BREEAM assessment type should be considered in line with KBCN0702

Knowledge Base – Applicability of UK NC 2018 KBCNs to UK NC V6 - KBCN1531

The assessment issues and criteria in BREEAM UK NC V6 are the same as BREEAM UK NC 2018 except for specific changes in:

• Ene 01 Reduction of energy use and carbon emissions
• Hea 02 Indoor air quality

The changes in Hea 02 do not affect the applicability of any current UK NC 2018 KBCNs All UK NC 2018 KBCNs for assessment issues other than Ene 01 are, therefore, applicable to UK NC V6. For Ene 01 we have reviewed and, where necessary, amended relevant KBCNs for UK NC V6. We are also taking the opportunity to update some of these for UK NC 2018.   Please also refer to the summary of changes for NC V6, provided in KBCN1530.

26/08/2022 Updated following review, to clarify that all current NC2018 Hea 02 KBCNs are applicable to UK NC V6.

Registering assessments to UK NC2018 or UK NC V6 – Version of Part L - KBCN1535

BREEAM UK New Construction 2018 was developed for buildings in England which are demonstrating compliance against Part L 2013. The New Construction V6 version is intended for buildings in England which are demonstrating compliance against Part L 2021. Accordingly, UK NC 2018 will only accept 'inp' files created using Part L 2013 building regulations software for England and UK NC V6 will only accept 'inp' files created using Part L 2021 building regulations software for England.   Assessments already registered to BREEAM UK NC 2018 that must comply with the Part L 2021 of the Building Regulations may follow either of the options below:

1.  Transfer to the UK NC V6 scheme
2. Assess under UK NC 2018 and do two Part L models:

• • Part L 2021 for statutory compliance
  • Part L 2013 for BREEAM purposes

New assessments subject to Part L 2021 may register to UK NC V6 or follow Option 2, above.

Retail/Industrial Showrooms Appendix - KBCN1115

This Criteria Appendix has been developed for developments such as car showrooms which incorporate both retail and industrial areas. The appendix clarifies, for specific BREEAM issues, which criteria are applicable to each area of the assessment. This should be read in conjunction with the relevant scheme version of the BREEAM UK  technical manual. This is applicable to BREEAM UK New Construction 2014, 2018 and V6 and BREEAM UK RFO 2014. Such assessments should be registered against the 'Retail' building type and the Appendix will soon be available for download in the guidance for 'Retail' assessments for each relevant scheme on BREEAM Projects. In the meantime, the Criteria Appendix can be requested by emailing [email protected]

22/09/2022 Applicability to UK NC V6 confirmed
22/05/2018 The title of this appendix has been changed and additional information provided. This includes removal of the specific reference to 'Car Showrooms' in order to clarify that this approach can be applied to other similar retail developments, which include industrial servicing areas.
