Laws, courts and authorities
GEG
Abbreviation for Gebäudeenergiegesetz
In short and in plain language
GEG is the old name of a German law on energy in buildings.
It sets rules for how much energy buildings need and for heating systems.
Today the law has a new name: the Building Modernisation Act. So older claims on the websites of heating firms may be out of date.
Definition
The Building Energy Act is the former name of the German law setting energy requirements for buildings and heating systems. It is now called the Building Modernisation Act, so older statements on heating businesses' websites may be out of date.
