The Federal Ministry for Economic Affairs and Energy (BMWi) promotes measures to increase energy efficiency.
You can receive a grant of up to EUR 48,000 for the following measures:

• Energy-efficient refurbishment of your residential building to a KfW Efficiency House

If you buy renovated living space, the costs of the energy-efficient renovation can also be subsidized. These costs must be shown separately (e.g. in the purchase contract).
You will not receive a subsidy:

• if the building application for your building or apartment was submitted after January 31, 2002,
• for personal contributions,
• for vacation homes, vacation apartments and weekend homes,
• for subsequent financing of projects that have already been started or completed,
• for photovoltaic systems,
• if you have already started the building project before submitting the application.

There is a benchmark for energy-efficient buildings, the KfW Efficiency House Standard. The lower the number, the more efficient your house is and the less energy you need.
The amount of the repayment grant depends on the KfW Efficiency House Standard of your building. The following standards are subsidized:

• KfW Efficiency Building 55:
  • You receive 40 percent of the eligible costs as a subsidy and at the same time
