Geothermal probes for the Einstein Congress St.Gallen

In the heart of the city St. Gallen a new convention centre is established. At the end of 2006 the operations for this complex excavation were taken up. The heating system should be modern and ecological - therefore geothermal energy was used. In this greatest construction ever built in Switzerland, a four-level underground garage with 280 parking spaces was developed. With the installation of a reservoir underneath the building the water resource can be used reasonable.

GEROtherm® horizontal heat exchanger

When planning to extend the production area of Gerodur an environmental protection should have been realised. So, this was implemented by the utilisation of free spaces as energetic heat exchanger surfaces. Therefore the temperature level of the sub-surface and the coldness of the surroundings are used to cool down production water in the low temperature range. Potential savings can amount to more than 450 tons of CO2 /year of operation.

Energy piles for skyscrapers in Frankfurt am Main

Through the use of heat pumps for a central production of coldness and/or heat, the capability of earth can be utilized multifaceted. So, energy pile systems are inexhaustible sources that are usable as a subsystem of complex production systems. One of these projects was the skyscraper Gallileo.

Wien: unique worldwide – underground railway station heated and cooled by geothermal energy

Geothermal energy can be used for heating and cooling ecologically friendly. The environmental effect is intensified by the system “enercret” of the company Nägele Energie- und Haustechnik by using existing parts of the building as heat exchangers. For the first time this environmentally friendly and cost-efficient procedure is used for the construction of the underground railway in Wien.
