Energy efficiency; application for a loan with repayment subsidy for municipal corporations for the refurbishment of non-residential buildings

If you invest in the energy-efficient refurbishment of non-residential buildings in the municipal and social infrastructure, you can apply for a loan with a repayment subsidy under certain conditions.


The Federal Ministry for Economic Affairs and Energy (BMWi) promotes measures to increase energy efficiency.
You can receive a loan of up to EUR 25 million for the following measures:

  • Energy-efficient refurbishment of a non-residential building in the municipal and social infrastructure into a KfW efficiency building.

  • Individual measures to improve the energy efficiency of non-residential buildings in the municipal and social infrastructure:
  • Insulation of walls, roof surfaces, storey ceilings and floor surfaces,
  • renewal and upgrading of windows, curtain walls, external doors and gates,
  • measures to improve summer thermal insulation,
  • installation, replacement or optimisation of air-conditioning and ventilation systems,
  • initial connection to local or district heating,
  • Renewal or optimisation of heat/cold distribution and storage,
  • renewal or optimisation of heat/cold generation,
  • replacement and/or optimisation of lighting,
  • Installation or optimisation of measurement and control technology and building automation.

The funding covers measures for the preparation, implementation and commissioning of the funded measure, such as ancillary work or planning costs.

You will not receive any subsidies

  • for the costs of a heat generator based on the energy source oil,
  • for cash loans and debt rescheduling of projects that have already been completed and financed,
  • if you have already started with the measure before submitting the application.

There is a benchmark for energy-efficient buildings, the KfW efficiency building standard. The lower the number, the more efficient your building is and the less energy you need.
The following standards are eligible for funding:

  • KfW Efficiency Building 70,
  • KfW efficiency building 100,
  • KfW efficiency building for listed buildings.

The amount of the repayment subsidy depends on the KfW Efficiency Building standard of your measure:

  • KfW Efficiency Building 70: You receive a repayment subsidy of 27.5 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 275 for each square metre of renovated net floor area.
  • KfW Efficiency Building 100: You receive a repayment subsidy of 20 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 200 for each square metre of renovated net floor area.
  • KfW Efficiency Building Monument: You will receive a repayment subsidy of 17.5 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 175 for each square metre of renovated net floor area.
  • For individual measures you receive a repayment subsidy of 20 percent of the loan amount. You can receive a maximum repayment subsidy of EUR 200 for each square metre of renovated net floor area.

You will only receive the repayment subsidy once you have completed your measure and provided KfW with proof that it has been carried out. To do this you must prove

  • that you have used the money for the measure applied for,
  • that you have achieved the KfW efficiency building standard or the energy savings.

You must keep all invoices and documents related to the measure.
