Phase 2 : Benchmarking and Indicators

The next phase is the establishment of a series of reference values for evaluating each of the criteria. As the reference conditions are different (because each building is unique) one must include a benchmarking phase, i.e. research of guide values which lead to evaluation of the chosen criteria. These guide values, which are determined by local laws and regulations, based on minimums for local construction and technical standards, and on scientific and other literature; form the basis of benchmarking.
