GEG (Gebäudeenergiegesetz) sets the legal framework for energy efficiency standards and the use of renewable energy in buildings (new construction and existing stock), covering requirements for building envelopes, heating systems, energy performance certificates (Energieausweis), and enforcement via fines (up to €50,000 for heating-related violations). Its most significant recent milestone was the 01.01.2024 reform (the so-called "Heizungsgesetz," §§ 71–72), which introduced a mandatory 65% renewable-energy share for newly installed heating systems. Its last amendment in 22.06.2026 brought an extension to the deadline from 30.06.2026 to 31.10.2026 to when the 65%-renewable-energy heating requirement would take effect for existing buildings in municipalities with more than 100,000 inhabitants.
