Overview of national applications of the Nearly Zero-Energy Building (NZEB) definition

Concerted Action (CA) on the Energy Performance of Buildings Directive (EPBD) has closely followed the process of setting up national applications of the Nearly Zero-Energy Building (NZEB) definition in the Member States (MSs) during the years 2012 to 2015. There was a continuous effort on presenting, analysing and discussing first ideas for the detailed definition, draft definitions, and definitions by front runner countries. By the end of April 2015, about 60% of the Member States (MSs) had already fixed their detailed NZEB definition in a legal document. Several others had draft definitions available that were under review by the government and other organisations.
This report includes the national applications of the NZEB definition as of April 2015 in all 28 EU MSs plus Norway, and it analyses how the required “very high energy performance“, the “very low amount of required energy” and the “numerical indicator of primary energy” have been specified in the national legislation. Moreover, it analyses whether there is a direct or indirect requirement for “a very significant contribution of renewable energy” in the national legislations.
