Ingenhoven Architekten GmbH

The architect’s office Ingenhoven Architects plans the building of the Oeconomicums on the southern campus of the Heinrich-Heine-University in Düsseldorf. The Oeconomicum is a three level building and has a bend building structure.

During the conception of the technical equipment for the building concentration lay on energetic characteristics and an innovative concept for heating and cooling of the building through concrete-core-activation, pre-warming and pre-cooling via ventilating systems and static heaters.

To fulfil the demands for environmental friendly energy supply a combined provisioning of local heat from the campus heating net and a heat pump supported geothermal supply for heating and cooling is planned.

The heat provisioning concept includes a heat distributor system consisting of a low- and a high-temperature net. The low-temperature net is supplied by a heat pump plant and includes following systems:

  • thermal building-part-activation (BTA)
  • pre-heater for the RLT-Tools
  • ceiling heater

The concept for cold-supply allots a monovalent supply via geothermal energy. The free cooling without cooling-machines occurs through the BTA, ceilings with cooling systems and central ventilating systems.
