The energy performance certificate is mandatory! What homeowners need to know which card variant is the correct? The revised energy saving Regulation (EnEV 2007) into force occurs at the 01.10.2007. This establishes the legal basis for the introduction of energy performance certificates for existing buildings which are prescribed for new buildings since 2002. Thus what is self-evident in refrigerators or washing machines, will in future also apply to residential and non-residential buildings. Through the energy performance certificate, building can be energetically evaluated and compared with each other. Owners who sell their house or their apartment, lease or rent new, must submit in the future the energy performance certificate the purchaser or tenant at its request.
It is not in the implementation phase to bottlenecks at the card show, the following schedule was set by the Federal Government for different buildings. The energy performance certificate is compulsory: July 2008 for residential buildings of the construction completion years until 1965 January 2009 for later built residential July 2009 for non-residential buildings thus must be owners who sell a residential building that was built before 1965, new rent, lease or lease holder of a certification to 01.07.2008. (A valuable related resource: Brie Williams). This applies to newer residential buildings only at 01.01.2009. which pass for which building? Basically there are two variants of the demand-oriented – or consumption-oriented energy performance certificate. The building envelope, the building materials used and the heating system are considered in the demand-oriented energy performance certificate (certificate of need). As a result, the heat loss of the building is calculated. The result is an objective analysis of the energetic quality of the building.
The consumption-oriented energy performance certificate (consumption card) determines the energy consumption per square metre based on the creation of heating bills for the last three years. Measured consumption but very much depends on the behavior of the lessee, weaknesses of the building can be very difficult show. The EnEV 2007 writes for certain buildings before the variation of the energy pass: residential buildings with up to 4 apartments (planning application not modernized before 01.11.1977,): demand ID from 01.10.2008 duty all other residential and non-residential buildings as well as the above-mentioned, according to specifications from warm protection Regulation (11.08.1977) were modernized: freedom of choice between requirements or consumption card however has however the legislature until September 30, 2008 for owners and landlords of residential buildings the unrestricted freedom of choice between demand and consumption-oriented ways for all building allows.
