Building LCA – Evidence requirements for two (or more) BREEAM assessments where the design is the same

Where an identical superstructure design* is used for two or more buildings, the same building LCA evidence may be submitted for the superstructure criteria, for each BREEAM assessment.

Where an identical core building services design* is used for two or more buildings, the same building LCA evidence may be submitted for the core building services design exemplary level criteria, for each BREEAM assessment.

It is unlikely that the same substructure and hard landscaping design will apply to more than one building due to variations in ground conditions/geology and site layout. Therefore, it is not acceptable for the same building LCA evidence to be submitted for the substructure and hard landscaping criteria, for more than one assessment.

*The following shall be identical: The products specified and quantities installed; transport of the products to the site (10km variation in transport distance to site is acceptable); in-use assumptions (e.g. maintenance, service lives of products); end-of-life assumptions.
