Mariannen-campus

At the Mariannen South and East Campuses, we rely almost exclusively on renewable energies. The use of fossil fuels is thus almost completely avoided. This is achieved by maximizing the use of solar energy and environmental energy from the ground. More than 3,800 m² of photovoltaic surface, 89 geothermal probes with more than 12,400 bore meters and at least KfW 55 for new building sections (many building sections even KFW 40 as well as KFW 100 for the southern existing buildings with monument protection requirements) are aimed at in order to become one of the first climate-neutral quarters in Leipzig. A photovoltaic system with approx. 1,500 modules and a module surface of 2,500 m² is planned for the building of the old station hall alone. This makes it the largest building-integrated photovoltaic system in Leipzig. The heat demand will be covered almost exclusively by the ground: for this purpose, 89 geothermal probes with a depth of approx. 140 m will be installed. The heat pumps for tapping the heat and cold from the ground are preferably supplied with green electricity from the photovoltaic systems. Many quantities of CO₂ will also be saved by using the existing buildings, which will be carefully integrated.
