GEG
Abbreviation for Gebäudeenergiegesetz
In short and in plain language
The GEG is the old name of a German law on energy in buildings.
It is about how much energy a building needs and how well it uses it.
Today the law is called the Building Modernisation Act. It still covers things like the energy certificate.
Some estate agents and landlords still use the old name on their website. Then the text may be out of date.
Definition
The GEG is the former name of the German law on the energy demand and efficiency of buildings. Today it is called the Building Modernisation Act and still governs, among other things, the energy certificate. Statements on estate agents' and landlords' websites that still refer to the GEG may therefore be out of date.
