Energy Saving Ordinance and Renewable Energies Heat Act

diese Seite auf Deutsch

New buildings under the scope of the Energy Saving Ordinance also have to comply with requirements given by the Renewable Energies Heat Act ("Gesetz zur Förderung erneuerbarer Energien im Wärmebereich (Erneuerbare-Energien-Wärmegesetz - EEWärmeG)") since 1 January 2009. This also applies to certain measures concerning existing buildings owned and occupied by public entities. This results in numerous reciprocal effects concerning the calculations and the proof of compliance. In particular, the partial use of renewable energies demanded by the Renewable Energies Heat Act can have a major impact on the primary energy demand according to the Energy Saving Ordinance.

The Federal Ministry of Economic Affairs and Energy - generally in charge of the law - provides documents and information on a separate website (German language only):
