The energy performance certificate is a convenient way for tenants, leaseholders and buyers to compare the energy requirements and consumption of buildings in Germany. It helps to estimate the potential costs for heating and hot water. The energy performance certificate, pursuant to the German Buildings Energy Act (Gebäudeenergiegesetz, GEG), contains information on the building and its heating, as well as on the property’s energy performance indicators. In a nutshell: it rates the building’s energy efficiency status.
The document or a copy must be submitted to interested persons no later than when they inspect a property; it must be handed over after completion of the purchase, lease or rent contract. In contrast, the energy performance certificate provides homeowners with points of reference for the energy-efficient refurbishment of their building: it systematically discloses a building’s energy deficiencies and simultaneously shows which measures can be implemented in order to improve the energy balance.
The energy performance certificate provides orientation
Like the energy efficiency label for electrical devices, the energy efficiency of buildings is classified on a sliding bar label with a colour scale from green to red to indicate their energy requirements or consumption. This enables costs for heating and hot water to be estimated. Moreover, the efficiency classes provide pointers for the building’s energy efficiency status. Therefore, the introduction of these classes should be welcomed in principle. But there are risks associated with the current assignment to classes based on energy requirements: it can produce misleading interpretations, as the difference in costs for energy sources and other facts may not be considered.
Issuers of energy performance certificates
Energy performance certificates are issued by experts who are qualified according to Section 88 of the German Buildings Energy Act (Gebäudeenergiegesetz, GEG).
Homeowners and investors will find issuers of energy performance certificates in dena’s Database of Efficient House Experts. Various experts listed in the Database of Energy Efficiency Experts for Government Funding Programmes are also entitled to issue certificates.
