Submit a declaration of compliance in accordance with Section 92 (2) of the Building Energy Act for existing buildings
The Building Energy Act (GEG) sets requirements for the energy performance of buildings. The client or owner of a heated or cooled building must prove that the building meets the requirements of the Building Energy Act.

Basic information
In the case of extensions and expansions as well as certain changes to buildings, the building owner must provide evidence of compliance with the requirements of the GEG. Proof of compliance with the requirements is provided in the declaration of compliance (Section 92 (2) GEG). The declaration of compliance must be submitted within 3 months of completion of the construction project.
Requirements
You must confirm that the requirements of the Building Energy Act (GEG) are met when extending, expanding or modifying the building if you extend or expand the building to include heated or cooled rooms (Section 51 GEG). You must also submit a declaration of compliance for changes for which calculations have been carried out for the entire building (§ 48 Para. 1, 50 Para. 1 to 3 GEG).
In these cases, the declaration of compliance may be issued by persons who are authorized to issue energy performance certificates in accordance with § 88 GEG.
You must submit the declaration of compliance in accordance with the model published by the Senator for the Environment, Climate and Science pursuant to Section 2 (1) (2) or (3) GEGV.
