Amended Energy Savings Ordinance Enters into Force on 1 May 2014

The latest amendment of the Energy Savings Ordinance (EnEV) will enter into force on 1 May 2014. It tightens requirements for new buildings as of 2016 and improves the quality of energy certificates to the benefit of tenants and buyers of buildings. A limited number of new requirements apply to existing buildings.

The revised EnEV transposes the recast Directive 2010/31/EU on the energy performance of buildings, the government’s Energy Concept of 2010 towards a renewable energy supply and  its energy policy shift of 2011 that accelerated the promotion of renewables and lead to the phase-out of nuclear power by 2022. EnEV is based on the Energy Savings Act (EnEG), which was also amended in 2013.

Below please find the main changes compared with EnEV 2009:

  • Requirements concerning the primary energy consumption of new buildings are tightened by 25% as of 1 January 2016. The maximum heat loss of the building’s envelope has to be reduced by on average 20%;
  • Regarding existing buildings requirements have been tightened with respect to boilers: Boilers operated with liquid or gaseous fuels installed before 1985 must not be used after 2015. If they were installed in 1985 or later they can only be used for a period of 30 years. Exceptions apply for low temperature and condensing boilers as well as for owners of houses occupied by only one or two families;
  • Further new requirements for existing buildings relate to the insulation of the last floor of residential buildings below unheated attic space;
  • Energy certificates will be rendered more informative, providing information not only in the existing range from green to red, but also by adding nine energy efficiency classes modeled on the ones used for household appliances, ranging from A+ (lowest energy use/consumption) to H (highest energy use/consumption). Existing energy certificates without energy efficiency levels remain valid;
  • Sellers and landlords are required to provide buyers or tenants with an energy performance certificate. It has to be presented already when prospective buyers or tenants come to view the property. Certain information on the energy efficiency even have to be included in real estate advertisements;
  • An inspection and control system for energy performance certificates is introduced;
  • A control system concerning the compulsory inspection reports on air conditioning systems introduced;

The Federal Association of the Energy and Water Industry (BDEW) called EnEV an important step on the way to reaching the goal of an almost climate neutral  building stock by 2050, but called for more state support in favour of energy efficient renovations.
