The Energy Saving Ordinance (EnEV) came into force in 2002. It replaced the Thermal insulation Ordinance (1995) and the Heating Systems Ordinance (1998). The Energy Saving Ordinance sets energy performance requirements for new buildings and for existing buildings in case of major renovation. In exceptional cases there are requirements to retrofit. For non-residential buildings, the calculation of the primary energy demand is based on the DIN V 18599. The Energy Saving Ordinance also regulates the issue and the display of energy performance certificates as well as their content. The certificates serve as an information about the energy performance of a building and they are supposed to give the possibility to compare buildings in terms of the energy performance (for further information see lines 1193 ff.).
The first amendment was in 2007. With the EnEV 2007, the Energy Performance of Buildings Directive (EPBD) 2002/91/EC was transposed into national law. The main point was die introduction of energy performance certificates (see lines 1193 ff.) In 2009 the EnEV was amended another time. The requirements were strenghtened by 30 % on average. This version (EnEV 2009) is actually in force. A further amendment is foreseen for 2014 by two reasons: On one hand, the recast of the EPBD (2010/31/EU) should be transposed into national law and on the other hand the requirements for new buildings should be tightended in consequence of the Federal Government's decision concerning the "Energiewende" and the "Energiekonzept" of September 2010 an June 2011.
