Research into near-surface geothermal energy at the F-W
The use of near-surface geothermal energy by means of geothermal probes represents an efficient and future-oriented alternative to conventional heating and cooling applications for building energy supply. Depending on the application, the geological subsurface serves as a heat source or sink. In contrast to deep geothermal energy, the subsurface is only thermally tapped to depths of max. 400 m in the case of shallow or shallow geothermal energy, which usually requires the support of a heat pump for the heating purpose due to the temperature level prevailing there.
Today, ground-coupled heat pump systems make a significant contribution to primary energy savings. They are therefore indispensable for the implementation of the German government's energy policy objectives. This technology can unfold its full potential above all in combined heating and cooling operation. However, there is still a need for research into planning methods, forecasting models and practical operating concepts in order to exploit the available efficiency and optimization potential.
Historically linked to the Department of Civil Engineering, the Faculty W of the Zittau/Görlitz University of Applied Sciences has been conducting research in the field of shallow geothermal energy since 2006. In addition to high-performance computer technology for the realization of complex numerical simulations (TRNSYS, FEFLOW), the scientists also have access to an extensively equipped geothermal probe test facility.
