The two universities are located side by side in the center of Berlin, adjacent to the Berlin Zoo and the main garden (Tierpark).
The campus has 44 buildings, 50.000 users (40.000 students) and 600.000 sqm area.
Sustainability strategy outline
The 3 primary objectives are to demonstrate the energy revolution.
– reduction of the useful
– efficient plant technologies
– reduction of primary energy demand.
Using a power supply analysis of locally available but unused renewable and alternative energy a maximum possible range is determined. A part of this project is, focusing on heating and cooling technologies. Wind power and photovoltaics, as well as other investments that are purely of electricity will not be considered.
The existing building data (consumption) together with the theoretical specific needs have to be balanced with the potential energy available. Using an exergetic, environmental, economic and political investigation concrete concepts for the campus area and the building supplies are developed. The main focus: local production of energy, where favorable conditions exist and a shift of energy flows to the needs. A new concept is created with the objective of maximum utilization of alternative and renewable energies. The primary energy consumption from fossil fuels should be reduced significantly for the campus, ideally to zero.
Innovations to be addressed
The main innovation is the combination of innovative techniques for heating and cooling to get a Green Campus.
The project objectives are to be realized mainly through 6 main activities:
a) Inner city biogas plant
b.) Hydrothermal carbonization
c.) solar thermal power plant as
d) geothermal (deep and shallow geothermal)
e) Innovative Wärme-/Kältenetz
f) remedial measures at the building level
The user behavior is also considered to optimize the energy demands.
