This document's full name is the Law on saving energy and using renewable energies for heating and cooling in buildings. It replaces the Energy Conservation Act (Energieeinsparungsgesetz, EnEG), the Energy Saving Ordinance (Energieeinsparverordnung, EnEV) and the Act on the Promotion of Renewable Energies in the Heat Sector (EEWärmeG). The new Buildings Energy Act sets out requirements for the energy performance of buildings, the issuing and use of energy performance certificates, and the use of renewable energy in buildings.
The Act was reformed in 2022, with the amendment entering into force at the beginning of 2023. The amended Act raised standards regarding new buildings and reduced the permissible annual energy demand in new buildings from 75% to 55%.
