The GEG registration point at DIBt issues registration numbers for energy performance certificates and inspection reports for air conditioning systems. Energy consultants and inspectors of air-conditioning systems can register with the GEG registration point and obtain registration numbers there.

The current legal basis for the registration is the Buildings Energy Act (Gebäudeenergiegesetz or GEG for short). However, registration duties have existed since 2014 on the basis of the Energy Saving Ordinance (EnEV).

As the GEG registration point, DIBt runs the technical platform for the registration of energy performance certificates and inspection reports for air-conditioning systems. The Institute is also responsible for carrying out electronic validity checks, which form the first stage of the control system for these data sets.The control stages 2 and 3 are carried out by the competent authorities of the federal states.
