HELIOS – SOLAR DISTRICT HEATING
SOLID planned and built the second and third construction phase of the project Helios in Graz
Menu
Thanks to the strong initiative of SOLID, the necessary stamina and the support of the federal government, the state and those responsible for the city of Graz, this pilot project was successfully implemented as a first of its kind.
Due to the fact that the energy generated by the solar system is constantly drawn off by the district heating system, there is no need for expensive buffer storages. The total collector area is 1.407 m2 – mounted on the roof of the skating hall of the Arena in Graz-Liebenau. A transfer station located in the mechanical room of the Arena manages the transfer of energy from the solar circuit to the district heating grid.
The solar plant is operated in an Energy Service model in cooperation with our partner nahwaerme.at Energiecontracting GmbH who was responsible for the proper operation of the plant, while SOLID was in charge of the design, planning and construction.
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.
