Zesumme renovéieren

Homeowners, municipalities, and Klima-Agence work together to improve the energy efficiency of residential buildings 

Benefit from Klima-Agence’s personalised support to successfully insulate your home and sustainably reduce your energy costs

Residential buildings constructed before 1996 can save up to 80% of energy, compared to their original energy consumption, through retrofitting insulation. This allows owners of such properties to enjoy lower heating costs and greater living comfort.

A dedicated point of contact, the Klima-Agence district manager, supports homeowners throughout the entire renovation process.

Homeowners receive a building factsheet with tailored information on the building type’s energy performance, potential insulation measures, and the relevant financial incentives available for their property.

Zesumme renovéieren: a joint responsibility of Klima-Agence and the partner municipalities

From 2023 to 2025, Klima-Agence launched and implemented the pilot project “Zesumme renovéieren” in cooperation with the municipality of Differdange and with the support of the European Union.

In 2025, the campaign “My municipality insulates now!” was implemented in Niederanven as part of the further development of the Zesumme renovéieren project.

In spring 2026, the campaign now also officially launched in the municipality of Schuttrange.
