clean energy park blurado

First climate-neutral business park in Germany

THE CHALLENGE

For the further development of the city, additional commercial areas are needed that ensure the future viability of Radolfzell as a medium-sized center and maintain the appropriate balance between working, living and residential space in the city. The special challenge for the location of Radolfzell: 82 percent of the areas in the city area are under protection, i.e. they are nature conservation, landscape protection, bird protection, green areas or fauna-flora-habitat directive areas. The development of the "Kurzer Sod" and "Fohrenbühl" commercial areas planned for the medium term is intended to meet demand.

THE GOAL

The complete abandonment of fossil fuels and best practice function for a partnership and cooperation between municipality, public enterprise and private sector. Placement of the commercial area and agrothermal areas must maintain an appropriate distance from surrounding biotope areas. Minimize interference with the soil structure by relocating the agrothermal collectors.

THE SOLUTION

The complete abandonment of fossil fuels is made possible by a cold local heating network, a so-called agrothermic system, as well as electricity generation by means of photovoltaic surfaces, which in addition to supplying the heat pumps also cover parts of the electricity consumption in the companies. In this way, the companies can rely on a CO2-neutral supply of heat and electricity.

In the case of energy generation through agrothermics, geothermal collectors are laid about two meters below the earth's surface in neighboring fields and meadows. These collectors use the temperature conditions of the soil and supply the commercial enterprises with heat in winter and, via so-called temperature recirculation, also with cold for air conditioning the buildings in summer. The photovoltaic system supplements the energy production in the industrial park. This autonomous energy supply makes the industrial park an innovative and unique project in Germany: a so-called Clean Energy Park.
