The Building Energy Act (GEG) is a key element of German energy and climate policy that affects property owners, developers and property buyers. Since its introduction, the GEG has pursued the goal of reducing energy consumption in buildings and promoting the use of renewable energies. For property owners, particularly in the metropolitan region of Nuremberg, Fürth, Erlangen, Schwabach and Roth, the law presents a number of requirements and challenges that need to be taken into account.
The GEG brings together regulations that were previously contained in the Energy Saving Act (EnEG), the Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Act (EEWärmeG). This simplifies the energy-efficient planning and utilisation of properties. In this article, you will find out which regulations the GEG contains and how property owners can adapt to them.
Challenges of the GEG
The Building Energy Act presents property owners with the challenge of making their buildings energy-efficient. The energy requirements of the GEG must be met, particularly in the context of new buildings or modernisations. However, certain requirements also apply to existing buildings that are sold or rented out, such as the Obligation to present an energy performance certificate. Fulfilling these requirements can lead to increased investment costs, but also offers long-term savings in energy costs.
What does the Building Energy Act (GEG) regulate?
Requirements for new buildings
The GEG stipulates that new buildings must meet certain energy standards. These include, among other things:
- Maximum primary energy requirementNew buildings must not exceed a certain primary energy requirement in order to minimise energy consumption.
- Renewable energiesThe use of renewable energies is being promoted. There are regulations stipulating that a certain proportion of energy requirements must be covered by renewable energies.
Requirements for existing buildings
There are also clear requirements for existing buildings. Certain energy standards must be met for extensive refurbishments or modernisations:
- Roof and façade insulationRefurbishment: Roofs and façades must be insulated accordingly to minimise energy loss.
- Obligation to replace old boilersOil and gas heating systems that are more than 30 years old must be replaced, unless they are low-temperature or condensing boilers.
Energy performance certificate and its significance
When renting or selling a building or a flat, a Energy certificate which provides information on the energy consumption of the building. The energy performance certificate is an essential basis for potential buyers or tenants to assess the energy efficiency of the property.
Tax benefits and subsidy programmes
Tax benefits or subsidy programmes are often available when energy-efficient renovation measures are carried out. These programmes can help to reduce investment costs:
- KfW funding programmesKreditanstalt für Wiederaufbau (KfW) offers low-interest loans and grants for energy-efficient construction and refurbishment.
- Tax depreciation and amortisationRefurbishment costs incurred to comply with the GEG are tax deductible.
Tips for property owners
1. plan early
For new builds or extensive refurbishments, you should find out about the requirements of the GEG at an early stage. Careful planning helps to avoid unnecessary costs and delays.
2. obtain expert advice
Property owners should seek advice from an energy consultant or architect to ensure that all the requirements of the GEG are met. Correct implementation saves costs in the long term and offers security.
3. use support programmes
There are numerous subsidy programmes that support the energy-efficient refurbishment of buildings. Take advantage of these financial assistance programmes to reduce costs and benefit from lower energy costs in the long term.

You must comply with the requirements of the GEG, especially for new buildings and energy-efficient refurbishments. The energy performance certificate is also mandatory when selling or letting.
The GEG reduces the energy consumption of buildings and promotes the use of renewable energies, which reduces CO2 emissions and supports climate protection.
Yes, KfW Bank subsidy programmes and tax write-offs can support refurbishment measures.
The energy performance certificate documents the energy consumption of a property and must be presented when selling or letting.
Oil and gas heating systems that are more than 30 years old must be replaced unless they meet the low-temperature or condensing boiler standard.
