Green Guide – Updated validity requirements - KBCN1466

It has been recognised that, due to the withdrawal of the Green Guide methodology in the current version of BREEAM UK New Construction, some manufacturers are not updating their product certifications against this environmental profiling scheme. Therefore, where robust evidence can be provided that the composition and properties of such products or materials have not changed since they were certified, the expired Green Guide Rating may be used, where available. This supersedes the guidance previously provided in relation to Green Guide validity in KBCN0798

Partial assessments - KBCN1001

Where the assessment covers only some of the floors in the building, the roof must still be assessed as it is protecting the assessed building below. If the roof is directly above domestic accommodation (e.g. flats), the equivalent domestic Green Guide rating for the roof must be used, as opposed to the ratings for non-domestic roofs. Roof areas not protecting parts of the assessed building or space can be omitted from the assessment.
