Abstract: The urban simulation platform SimStadt calculates heating demand for city quarters or whole cities based on 3D building information data. In this study, SimStadt’s capabilities to dimension centralized and decentralized heat supply options are extended and tested for a city quarter of 65 buildings in Mainz, Germany. A biomass-fired boiler with an oil-fired backup boiler and a heating network is compared against a decentralized solution based on air-water heat pumps along technical and economic indicators. Furthermore, heating demand simulation results are validated against measured data and show differences of as little as 4%, while simulated and measured heat generation for the biomass supply option deviate by 5% only.
