The German Energy Saving Ordinance (EnEV) is a central instrument within German energy and climate protection policies. Its purpose is to ensure that the targets of the Federal Government’s energy policies are achieved – in particular a largely climate neutral inventory of existing buildings by 2050 and around 60 percent savings in final energy consumption through efficiency measures on the building envelope and construction technology compared with 2010. The ordinance defines structural and heating system standards for buildings and specifies the energy efficiency for new builds and the refurbishment of existing buildings. EnEV is based on the Energy Saving Act (EnEG); its effectiveness is further supported by other standards and laws such as the Renewable Energies Heat Act (EEWärmeG).
