This supersedes the guidance in:
- BREEAM Refurbishment Commercial V7.0
- BREEAM International New Construction V 7.0
- BREEAM UK New Construction V 7.0
Where the new-build area is < 50% of the project gross internal area:
- BREEAM Refurbishment can be used.
- The scope of the assessment for the new-build element must align with the Parts selected for assessment, which must include Part 1.
Where the new-build area is ≥ 50% of the project gross internal area:
- A single BREEAM Refurbishment assessment is not appropriate.
- RFO-NC Bespoke assessments are no longer available.
The options are:
- Separate BREEAM Refurbishment and BREEAM New Construction assessments Two separate certificates will be issued to indicate the performance of the new-build and refurbishment areas respectively.
- BREEAM New Construction A single New Construction assessment can be used for the whole development, regardless of the percentage of new-build area. Both the new-build and refurbished areas must be assessed against the more challenging New Construction criteria.
