The building consists of 2 basement floors, ground floor and 6 upper floors. The building extends in a north-south direction and directly adjoins the existing Internal Medicine North building and the low-rise Frauen-Kopf-Klinik building.
The production of an excellent building envelope and a surface heating in the low temperature range create optimal conditions for the efficient use of groundwater heat pumps. The room cooling as well as the cooling of medical equipment is carried out via thermal groundwater utilisation which covers a total of approx. 80 % of the cooling capacity in the building. In order to use the existing groundwater as efficiently as possible, it is used in several stages to bring it up to the approved temperature level. With the implementation of these measures, approx. 600 t CO2 per year can be saved by the efficient use of groundwater alone. An efficiency of at least 77 % is achieved by using a high-performance heat recovery system in the ventilation system. In lighting, the use of LED technology, dimming, time control and motion detectors offers further potential energy savings.
