Cost optimal building performance requirements
In the recast Energy Performance of Buildings Directive (EPBD) adopted in May 2010, a benchmarking mechanism for national energy performance requirements was introduced. The purpose of this is to determine cost-optimal levels to be used by Member States for comparing and setting these requirements. The previous EPBD (from 2002) set out a general framework to assess the energy performance of buildings and required Member States to define maximum values for energy delivered to meet the energy demand associated with the standardised use of the building.
