Annex I to the EPBD sets out a common general framework for calculating buildings’ energy performance and, inter alia, describing national methodologies. To meet the objectives of energy efficiency policy for buildings, energy performance certificates (EPCs) should be made more transparent by ensuring that all necessary calculation parameters, both for minimum energy performance requirements and for certification, are set out and applied consistently.
Annex I to the EPBD has been amended in 2018 for improving the transparency and consistency of the 33 different regional and national energy performance calculation methodologies. It now requires Member States to describe their calculation methodologies in line with the energy performance of buildings (EPB) standards.
Although the EPBD does not require Member States to refer to the EPB standards as the calculation method for EPCs and compliance with minimum energy performance (legal) requirements, adopting the EPB standards is the simplest and recommended option.
As stated in the recital of the EPBD: “…the recognition and promotion of the EPB standards across the Member States would have a positive impact on the implementation of the Directive.”
Also: “…the comparative methodology framework to identify cost-optimal levels of energy performance requirements for buildings and building elements … should be based on relevant European standards relating to this Directive.”
