The basis for the standardization work to be carried out by CEN, CENELEC and ETSI is found in the current set of Energy Performance of Buildings Directive (EPBD) related CEN standards, as well as other existing national, CEN/CENELEC and ISO standards.
The improved set of EPBD standards shall become a systematic, clear and comprehensive package for the benefit of professionals, Member States and relations with third countries.
In order to ensure user-friendliness, a continuous but modular overall structure is needed, covering all standards related to the energy performance of buildings, providing the overall framework which will enable a step-by-step implementation by the EU Member States.
The mandated works will include guidance on the rationalization of different options given in the standards, providing a balance between the accuracy and level of detail, on one hand, and the simplicity and availability of input data, on the other. Hidden complexities will also be taken into account, such as the impact of differences in the overall legal frameworks on the national choices and national input data.
