One often reads property descriptions such as these: The building will have the KfW Energy Standard 55 (or similar). But what does this actually mean?

Energy standards are laid out in the Energy Conservation Ordinance (Energieeinsparverordnung/EnEV). These standards, lets say 85 or 55, indicate the energetic quality of a building. As lower the number, as better it is.

A normal new erected building provides a quality of 100. A 100 building is in accordance to the german building rules, but not very special energy-efficient. A socalled  KfW-efficience-building 85 consumes 85 percent of the energy, a normal (100) building spends. A efficience building KfW 55 consumes 45 percent less as a comparable usual new building.

KfW-efficience-buildings 55 need special fittings to earn the certificate: wooden pellet or biomassheating or thermal pumps, a thermal solar system for drinking water heating, external insulation, roof insulation, windows with triple glazing and special frames. This increases the builders costs, but it provides an excellent technical quality a futurly cost savings in regards to the utilities. 

To stimulate this, public banks have to agree:

  • a loan up to 100.000 € (interest rate 0,5 percent p. a.) per apartment bought
  • up to 5.000 € grant (only usable as repayment installment)
