  Prof. DI Georg Lippert
The basis area consists of approximately 24,000 m² (Measures: 130 m x 130 m – height, round 26 m)
Technical project
The heat supply is provided with the district heating. The heating of the offices is produced by fan coils (heating/cooling). The heating of the lounges, respectively customers’ areas is supplied with radiators, fan coils, floor-heating or through ventilation, as per need.
At the refrigeration system’s disposal there are 3 turbo cooling machines and a heat pump. These installations serve the cooling of the offices, kitchen, lounges and computing center. The heat loss from the computing center is conducted through the heat pump to the heating system. Thus, a large portion of the heating demand of the rooms and of warm water production can be covered.
For the room ventilation there are 24 ventilation facilities foreseen. Common water from an incorporated well delivers water for toilet flushing, façade cleaning and sprinklers for green areas. The power supply is provided with 2 separated 10 KV power supply storage from the Handelskai transformer station.Â
