Habelschwerdter Allee 45 - "Rostlaube"

The so-called “Rostlaube” was built between 1967 and 1973 and serves, together with the “Silberlaube”, as the central lecture and seminar room complex at Freie Universität. As a result of extensive renovation work (1999-2007), the building’s heating requirements were reduced by over 26 % in comparison to the year 2000. A 97 kW photovoltaic system on the roof produces just under 87,000 kWh of electricity annually. Around one third of this system was funded by the student project UniSolar.
