Hands-on energy transition
The EUREF-Campus Düsseldorf is smart in terms of energy: a high-tech energy centre and the use of solar power and other renewable energies make the EUREF-Campus Düsseldorf a showcase project even before it goes into operation. It will be part of a network of environmentally friendly energy producers as well as storage facilities in the region.
EUREF, Stadtwerke Düsseldorf and BLS Energieplan have drawn on local conditions and resources to develop the energy concept. The energy turnaround is there to touch: electricity and heat are generated in an environmentally friendly way.
The combined use of renewable energy sources forms the core of the innovative energy concept of the new EUREF-Campus Düsseldorf.
The aim is to supply the campus in a CO2-neutral and safe manner. And this with an annual building energy demand of 2.4 gigawatt hours for heat and 2.7 gigawatt hours for air conditioning.
This is achieved, for example, through the thermal use of the adjacent Lichtenbroich quarry pond, a gigantic heat reservoir that supplies both heat in winter and cold in summer through highly efficient heat pumps. Another innovatively used source of energy is the sun, which provides electricity for self-consumption all year round with the help of PV systems on the roof and façade of the Innovation Campus. The ambient air is also used to cool the building and dissipates excess heat via a hybrid cooler. Stadtwerke Düsseldorf also supplies the building with climate-friendly district heating on particularly cold days – this is already making a contribution to achieving the climate protection targets of the city of Düsseldorf by 2035 and of the federal government by 2045.
The immediate proximity to the Lichtenbroich quarry pond makes it possible to use lake water. The lake water station is an important component of the energy concept. Here, two pipes are inserted into the lake: one into the upper and one into the lower water layers. Water from the lake water station flows through a strainer into a heat exchanger, which heats the lake water in summer and cools it in winter. Then the water flows back into the lake with a temperature difference of about 2-5° C (warmer or colder), biologically and chemically unchanged and thus harmless.
In the process, the quarry pond acts as a heat source in winter and a heat sink in summer. The water on the secondary side, which is heated or cooled by the lake, is then temporarily stored in a source reservoir and is then used either for direct temperature control of the building or as a source for the highly efficient heat pumps. The concept is complemented by an intelligent energy management system from Schneider Electric – the Microgrid Advisor. This links all energy generators – seawater, heat pumps, solar energy, hybrid coolers, district heating, energy storage and charging infrastructure – into an integrated energy infrastructure.
