HotSpot – Storage of solar heat at a directly usable temperature level in the ground

Requirements and possible sites in Switzerland

The Drake Landing Solar Community has raised worldwide attention, when covering 100% of space heat for an entire quarter of single family houses with a concept of solar thermal collectors and a central borehole storage. In this project it was analyzed weather a similar concept can be realized in Switzerland. Therefore the legal conditions were summarized and the economic requirements were evaluated. A GIS based analyze shows, which locatios are specially suited for such a concept based on solar irradiation and geological conditions.
