What is an Energieeffizienzkredit?
An Energieeffizienzkredit is a financing loan specifically designed for renovating buildings and improving their energy efficiency. It aims to support measures that reduce energy consumption and lower CO₂ emissions, such as thermal insulation, replacing windows, upgrading heating systems, or installing solar panels.

Advantages of an Energieeffizienzkredit

• Very low interest: starting below 1% in some programs, making financing affordable.

• Financing up to 150,000 euros per residential unit: depending on the renovation scope.

• Additional support (Tilgungszuschuss): in some cases, a grant may reduce the repayment amount.

• Flexible repayment: terms up to 30 years, with a possible grace period (tilgungsfreie Anlaufzeit).

• Increased property value: renovations raise market value and improve attractiveness for sale or rental.
