We are working on a holistic concept for efficient energy supply "post2030" for the Lichtwiese campus. In the interdisciplinary EnEff:Stadt Campus Lichtwiese project, both the electrical energy supply and the heating and cooling requirements of the university are being considered. Comprehensive monitoring of the energy flows on campus forms the basis for a fundamental modernization strategy.
Within the first project phase until 2018, significant potentials for increasing energy efficiency and reducing energy demand were evaluated. The measures considered here were evaluated with regard to their real structural and energy-related developments. On the basis of various scenarios, it was determined which future developments will arise for the tasks of the electrical network at the Lichtwiese campus and what effects these will have on network operation. For a number of reasons, the campus is particularly suitable as a study object:
To increase the efficiency of the heat supply, the temperature reduction in a district heating system is an important topic of research. Campus Lichtwiese serves as an example of how low temperatures can be achieved not only in new district heating networks, but also in existing networks.
The recommendations for action of the first phase of the project are summarized in a brochure. The focus was on the development of renovation strategies for the existing building stock, thermal grids, modeling of the energy supply, potentials of the use of photovoltaics, integration of e-mobility and the impact of the use of heat pumps on the electrical grid.
In the EnEff Campus project, scientists from the fields of electrical engineering, mechanical engineering, architecture and computer science conduct interdisciplinary research on the energy turnaround in the area.
