Development of a decision framework for the selection of priority areas for the implementation of sustainable heating technologies

Up to now, the selection of priority areas for the implementation of sustainable heating technologies has focused on the determination of heat demand densities. In the federal provinces, there are very different instruments of energy planning and spatial planning. Especially Vienna can be seen as best practice here with its current climate protection areas. Other federal states have some catching up to do here. At the same time, various laws are currently being developed at the EU level, which will influence decisions regarding heating technologies (e.g. in RED III, introduction of so-called "go-to areas" for certain renewables). On the national level, the EEC will set essential framework conditions, especially the centralization requirement of formerly decentralized heating systems. The objective of the "CleanHeatSelector" project is to develop a decision-making framework for the selection of priority areas for the implementation of sustainable heating technologies. Specifically, the following sub-goals are targeted: - Analysis of the national and international legal framework (in particular RED III, but also the Energy performance of buildings directive, etc.) as well as the relevant contents of the EEC, EAEC, EGG, etc. - Analysis of the energy spatial planning instruments of selected federal states, especially Vienna as a best-practice example, but also the respective instruments of Styria, Salzburg and Upper Austria are analyzed. - Creation of a technology matrix, in which for characteristic areas in Austria (combination of demand characteristics and generation potentials e.g..: Waste heat, geothermal energy, etc.) different heating technologies are evaluated (economic, ecological, acceptance), including an assessment of the risks. - Consolidation of the results and preparation of policy recommendations for the selection of priority areas for the implementation of sustainable heating technologies.
