As the responsible sourcing assessment work must cover the whole new building design (see KBCN1217 ‘Measuring Responsible Sourcing – Scope when a BREEAM Assessment covers only part of the new building design’), it is equally applicable to all BREEAM assessments being carried out on the building, with the exception of internal finishes.
If the assessment scope does not include any construction products classified as ‘3. Internal finishes’, the same responsible sourcing assessment evidence may be submitted for each BREEAM assessment.
If the assessment scope does include construction products classified as ‘3. Internal finishes’, then the responsible sourcing assessment evidence submitted must be unique to each BREEAM assessment.
