Strategic energy supply concepts for heat planning test area clusters

Client: Landeshauptstadt München, Referat für Klima- und Umweltschutz

Duration: March 2025 – December 2025

Background

The transformation of heat supply presents a central challenge, particularly in urban areas, on the path to climate neutrality by 2045. While Munich, with its extensive district heating network, has generally good conditions for sustainable heat supply, district heating is not the optimal solution in all parts of the city. The heat plan for Munich, adopted on May 15, 2024, provides strategic guidance for an ecologically and economically sustainable heat supply in most areas. Both centralized and decentralized renewable heat supply solutions have been identified. However, in certain so-called “assessment areas,” which account for about 4% of the city’s building blocks, there is an increased need for more detailed concepts due to heterogeneous building structures and varying energy source conditions.

Goals and Results

The main goal of the project is to develop strategic energy supply concepts for three selected assessment area clusters. These clusters were chosen based on their cohesive structure and their representativeness for other assessment areas. In addition to creating these supply concepts, a methodology will be developed to enable the systematic transfer of results to further assessment areas.

For this purpose, existing data from the “Modell München” will be supplemented by an app-based on-site data collection to analyze building age, renovation conditions, and potential land uses more precisely. The developed heat supply solutions will include both centralized and decentralized climate-neutral heating options and provide short-, medium-, and long-term measures for the heat transition. The results will be presented to the Munich City Council as well as residents and property owners as a basis for decision-making to ensure broad acceptance of the proposed measures.
