GEG / EnEV calculation aids and information

The verification procedure for residential buildings in accordance with the Building Energy Act 2023 is available as part of a calculation tool based on Microsoft Excel. The tool is based on the calculation methods from DIN V 4108-6 and DIN V 4701-10.

With version number 4, the transition from GEG 2020 to GEG 2023 was implemented with the calculation sheet in January 2023. The main changes compared to the GEG 2023 version can be summarized as follows
