Project description

Spatial Energy Planning (SEP) has the potential to fundamentally change the heating sector and integrate innovative, sustainable heating technologies into a future energy system. In the "Spatial Energy Planning" project, planning principles for the spatially optimised development of the heat supply infrastructure were developed, taking into account the local framework conditions, such as the existing energy infrastructure, land use and available energy resources from renewable sources or waste heat.

The foundations created were incorporated into the digital HEATatlas, which shows the complex interrelationships in energy systems and thus makes long-term energy and infrastructure planning possible with greater investment security. In addition, a HEATapp prototype has been programmed that allows automated queries and can be used in three concrete areas of application in public administration: Site development, spatial planning and monitoring of energy strategies.

The federal states of Vienna, Styria and Salzburg were directly involved in the "Spatial Energy Planning" project; the development work was carried out together with a large number of partners from research and selected pioneer municipalities and cities, which provided reliable data for HEATatlas and HEATapp.

Together with cooperation partners, e7 developed methods and concepts for various heat-related aspects such as demand, density, renewable energy potentials (e.g. waste heat and geothermal potential), infrastructure, dynamic aspects of future developments and zoning. e7 was responsible for the heat supply contracting process in a pilot project and developed documents for the heat supply contracting in coordination with possible output data from the HEATapp.
