The project Siemensstadt Square develops a smart campus for the future combining digitalization, energy efficiency and sustainability. The sustainable supply of heating and cooling for the smart campus is a key challenge of the project. It is crucial to make the best possible use of the local supply of renewable heat sources and to distribute them efficiently in the urban context of the district. To support this process, we mapped the district in our heatbeat Digital Twin and then simulated and evaluated different options for the supply.

The central part of our work was the comparison of different heating and cooling network concepts to supply the district. This allowed us to show the advantages and disadvantages of the different concepts in detail and thus contribute important findings for the further planning process. In particular, we focused on questions regarding the network design (e.g. 2-pipe network vs. 4-pipe network), the integration of different heat sources (e.g. air and wastewater heat pumps) and the delineation of the supply area with a comparison of the heat densities of different construction sections.
