The beginning of the history of solar dirstict heating in central europe

On the roof of the skating hall of the Stadium in Graz Liebenau, a solar thermal system with 1407 m² collector surface was built on an ESCo basis. This system feeds the generated energy into the municipal district heating network and thus supplies the buildings connected to the district heating network in the area with heat for space heating and hot water preparation. With the necessary self-confidence and trust in the solar thermal technology SOLID and the partner company nahwaerme.at set new standards in 2002 with the construction and operation of this back then unique system for solar district heating in Central Europe.

The reduction in CO2 emissions of around 250 tonnes of CO2 per year significantly contributes to the achievement of the climate alliance goals of the city of Graz on the one hand and furthermore helps to reduce fine dust pollution in the city.
