Thermal Insulation in Existing Buildings

This program supports property owners and apartment owners' associations in Hamburg with the energy-efficient modernization of their single-family homes and small multi-family houses. The main goal is to reduce CO2 emissions and conserve energy resources by improving thermal insulation in existing buildings.

Comprehensive measures for the energy-efficient modernization of the building envelope, the use of sustainable insulation materials, specific work on brick facades, and quality-assuring accompanying measures are funded. The measures aim to improve energy efficiency and reduce heat loss.

Funding is provided as a non-repayable grant. The amount of funding varies depending on the building component and can be increased by modernization bonuses of 20% or 30%. A maximum of €50,000.00 per residential unit is eligible for funding, with a minimum funding amount of €500.00.

To receive funding, applicants must meet certain technical and procedural conditions. These include performing hydraulic balancing, engaging specialist companies and experts, and complying with specific U-values and material requirements. In addition, de minimis aid must be observed.

The application procedure is carried out electronically via the portal of the Hamburgische Investitions- und Förderbank (IFB Hamburg) and requires submission before the start of the measure. IFB Hamburg supports and advises applicants throughout the entire process.

The "Thermal Insulation in Existing Buildings" funding program is based on a specific funding guideline of the Free and Hanseatic City of Hamburg, which came into force on April 3, 2023. This guideline regulates the funding modalities for the energy-efficient modernization of residential buildings.
