Goals and results

In order to achieve these goals, IREES develops concrete technology solution proposals in the heat plan to derive short, medium and long-term measures in a heat transition strategy. In the first step, after clarifying the initial situation and the procedure, we carry out an inventory and potential analysis for heat sources and sinks. The potential analysis is carried out in high spatial resolution using a GIS-based digital city twin. It includes an analysis of the expansion and redensification potential for heating networks as well as local heating potential and a determination of the potential for renewable energies (RE). As the heat transition strategy aims to transform the heat supply through specific measures, concepts and solutions are assessed in as much detail as possible from a techno-economic and ecological perspective. Reference building types as well as neighbourhood structures, greenhouse gas emissions and spatial heat densities and network expansion and operating costs are taken into account in order to compare decentralised and centralised heating network-based heat supply solutions. To this end, IREES simulates various development scenarios that take into account political goals and instruments, economic factors, various refurbishment advances, technological progress, personnel capacities in the skilled trades and other factors.
