Technical assessment of the national/regional calculation methodologies for the energy performance of buildings

Directive 2010/31/EU on the energy performance of buildings (EPBD) defines the energy performance of a building as the energy needed to meet the energy demand associated with the ‘typical use’ of the building. An appropriate method to measure and calculate the intrinsic performance of buildings is necessary to further elaborate any policies in that field (minimum requirements, rating for certification purposes, etc.). Directive 2010/31/EU leaves the responsibility to adopt the calculation methodology to the Member States, at national or regional level, as far as the methodology fulfils the common general framework laid down in its Annex I.

The purpose of this study is to provide the Commission with structured descriptions of national/regional calculation methodologies under Directive 2010/31/EU, whether these calculation methodologies comply with the general framework of Annex I and whether these could be transparently described using the set of EPBD standards that CEN is currently developing under Mandate M/480
