Energy Saving Ordinance (Energieeinsparverordnung)

The Energy Saving Ordinance EnEV has been published by the "Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety" (Bundesministerium für Umwelt, Naturschutz, Bau und Reaktorsicherheit) and is updated consistently. In the EnEV are specified energetic standards and requirements for old-building renovation and new buildings intended for exploiting the full energy saving potential.
