The set of Energy Performance of Buildings standards, developed by CEN under mandate M/480, provides a methodology to calculate overall energy performance of buildings supporting the EPBD. They provide EU Member States with a toolbox to help the implementation of the Directive and aim also at higher transparency regarding the energy performance calculation methodologies. Each EPB standard has a template for a national annex that enables Member States to tailor the methodology to the national situation.
REHVA and ISSO have created the EPB Center as a joint organisation with the aim to support the uptake of the new set of EPB standards that signed a service contract with the European Commission to develop and launch its services. This virtuous circle of implementation-application-improvement, fed-in by standards experts and users, plays a crucial role in the actual use of these standards at local level.
