In Vienna, a new urban area “VIENNA TWENTYTWO” arises
Experts from our contacting and building technology companies designed, planned, and realized this project in close cooperation. Fossil fuels had to be avoided, without compromising on comfort. We invest in the technical installations and supply 100% CO2 neutral heating and cooling for the next 23 years.

Problematisation and customer issues
Old gas-fired boiler system had to be replaced
The gas-fired boiler system that supplied steam to the DSM Nutritional Products production facility in Sisseln was out-of-date and had to be replaced. There was a clear goal in mind – to create a progressive, sustainable system and make fossil fuels a thing of the past. The new solution also had to create value for the region and make use of local energy sources.
Our response
CO2 neutral energy concept for urban development
The energy supply concept covers the heating demand of around 7.7 MW and a cooling demand of around 5 MW. The heat pumps use thermal heat from wells and geothermal energy and are powered by 100% renewable electricity. During winter, the CNS extracts thermal energy from the exhaust air and heats the buildings. In summer, the CNS works the other way around and cools the fresh air. Excess heat and cold are stored in various buffer tanks, i.e. our innovative solutions also uses the water in the sprinkler basins. Each apartment, office and hotel room can be heated and cooled individually. The floor heating and ceiling cooling in all rooms ensure highest comfort.
