Energy Efficient University Campus Berlin-Charlottenburg (EnEff: HCBC)

Based on the energy transition target of the German government, the Campus Charlottenburg (TU Berlin and UdK Berlin) wants to establish itself as an energetically exemplary institution. To this end, the site at the University Campus Berlin-Charlottenburg (HCBC), which consists of buildings of different building stock, is to be reconstructed/refurbished in such a way that the 2050 heat transition targets can be demonstrated in parts as early as 2023.

The engineering geology department will focus primarily on the use of the urban subsurface for geothermal heat storage. The aim here is to integrate the existing foundation collector under the university library into the general concept for supplying heat to the building. In addition, geothermal storage will be integrated into the university's future heating and cooling network for sustainable and efficient management. Strategies for effective integration into these networks will be developed.

In cooperation with the company UIT Umwelt- und Ingenieurtechnik GmbH Dresden, we are working on LowRaWan groundwater temperature measurement systems for monitoring the temperature development in the subsurface in real time.
