Erratum – Part new-build, part refurbishment projects  - KBCN1903

This supersedes the guidance in:
Where the new-build area is < 50% of the project gross internal area:
Where the new-build area is ≥ 50% of the project gross internal area:
The options are:
  1. 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.
  2. 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.
Definition Project gross internal area – The combined gross internal area of the refurbishment and the new build.
