Mürzzuschlag is a town of 8,500 inhabitants in a mountain region between Vienna and Graz. It’s district heating system used to be fired by natural gas and biomass boilers. As both are scarce ressources, the integration of solar thermal was very much appreciated.
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
The installed heat storage, with a capacity of 165 m³, results in an overall efficiency increase via energy management.
Energetika Vransko, the local utility, wanted to increase their green energy supply to the district heating system. The signs were good – especially lucrative funding instruments removed all doubts in the investment of this first of its kind solar district heating system.
The village of Liggeringen is in the hills in the vincinity of Radolfzell at Lake Constance in Southern Germany, close to the Swiss border. There are mainly single family houses, but still it was viable to build a new district heating grid. As the utility
In order to get one step closer to becoming the solar capital of Europe, the City of Graz and the urban energy utility company Energy Graz decided to work with SOLID to develop this flagship project on the grounds of the water works Andritz, the
SOLID goes to the Caribbean: The energy supply of islands is complicated, expensive and very CO₂ intensive. Stand-alone solutions are optimized on the client’s energy demand and help to save expensive conventional energy sources.
The new campus was designed with support by SOLID’s concept for large-solar-thermal-systems, to fulfill the criteria of the Green Mark Platinum Certificate. The Green Mark Platinum certificate by the Building and Construction Authority of Singapore is the highest possible certificate for environmental friendly buildings.
The solar thermal plant, with in total 790 m²/8,500 ft², supports the energy supply of domestic hot water system, heating system, air-conditioning system (via absorption chiller) and feeds solar heat into the existing district heating grid.
