The Energy Performance of Buildings Directive (EPBD)

The set of EPB standards play a key role to support the Energy Performance of Buildings Directive (EPBD) of the European Union.

The EPBD aims to promote the improvement of the energy performance of buildings within the European Union, taking into account outdoor climatic and local conditions, as well as indoor climate requirements and cost-effectiveness. (Article 1).

The first version of the EPBD was published in 2002 (Directive 2002/91/EC). In the interest of clarity the EPBD was recast in 2010 (Directive 2010/31/EU).

A revised version of the EPBD was published in 2018 (Directive 2018/844/EU).

Revised EPBD in 2018: stronger role of the EPB standards

From the amended (2018) text of EPBD Annex 1, point 1:
Member States shall describe their national calculation methodology following the national annexes of the overarching standards, namely ISO 52000-1, 52003-1, 52010-1, 52016-1, and 52018-1, developed under mandate M/480 given to the European Committee for Standardisation (CEN). This provision shall not constitute a legal codification of those standards.

Although the new EPBD does not force the Member States to apply the set of EPB standards , the obligation to describe the national calculation methodology following the national annexes of the overarching standards will push the Member States to explain where and why they deviate from these standards. This will lead to an increased recognition and promotion of the set of EPB standards across the Member States and will have a positive impact on the implementation of the Directive.

Five ‘overarching’ EPB standards explicitly mentioned in the new EPBD:
The EPBD lists five EPB standards as 'overarching'. The meaning of the terms 'overarching' in the new EPBD and in the modular structure of the set of EPB standards only partly overlap. In the modular structure the term overarching refers to the standards that deal with the overall energy performance of a building (module M1), while other modules deal with the building as such (M2) or specific technical building systems or services (M3 etc.)
The five ‘overarching’ EPB standards ISO 52000-1, 52003-1, 52010-1, 52016-1 and 52018-1 have in common that each of these describes an important step in the assessment of the energy performance of building:
