Environmental Benchmarking for whole building assessment

A substantial benchmarking exercise has been undertaken as part of the IMPACT project to enable whole-building environmental assessment. For each building use type a sample of typical buildings (known as archetypes) are assessed and combined into a single benchmark representing average performance. The performance of a user’s building can then be compared to the benchmark in order to assess performance. This approach has been developed for integration with whole building assessment schemes like BREEAM.

It is anticipated that users who use IMPACT results as part of a BREEAM assessment will submit their BIM to BRE Global to contribute to the sample of buildings used to create the benchmarks. In this way, the base-line performance set by the benchmark will become progressively more challenging in line with overall market attainment.
