The portal "hausbauhelden.de" provides an article about the energy efficiency classes for buildings. This shows that the energy certificate is a component of the building energy law (GEG) introduced in 2021 and provides information about the climate impact of the building. On the energy certificate, for example, information on the final energy demand or the energy efficiency class can be found.
The energy efficiency classes are differentiated from A+ to H. Energy efficiency class A+ (green area) is considered the best, while energy efficiency class H is the worst (red area). Energy efficiency class A+ applies to a KfW Efficiency House 40 Plus, while energy efficiency class H applies to unrenovated houses, for example. The better the energy efficiency class, the lower the final energy costs.
The energy certificate is of interest to various target groups, such as real estate sellers, real estate seekers and home builders. Real estate sellers can deduce from this document whether modernization or renovation measures are worthwhile before the sale in order to raise the value. Property seekers can calculate the final energy costs they will face. House builders can benefit from building a KfW Efficiency House 40 Plus (A+) to get the highest possible subsidy from the state. The portal "hausbauhelden.de" points this out.
