At the company site of the Abfall Entsorgungs- und Verwertungs GmbH (AEVG), a collector area of 3556 m˛ has already been implemented.
The plant is currently Europe’s largest solar energy plant directly fed into the district heat grid. The extension of this plant within the AEVG, and at the company site of the district heating plant, is at planning and implementation stages respectively.
Solar energy plant on four different buildings. This project differs from others as the plant was installed on four different buildings. Each roof area can thus be separately regulated and locked off.
Each individual sub-array on the roofs also features facilities for shut-off and at least one bleed point.
To guarantee optimum control and thus the efficient running of the plant, each collector array has a heat sensor. All temperatures are transmitted to the control cabinet located in the covered area, before they are passed on to the control system in the transfer station. The solar energy obtained will then be transported to the central services complex via a main conduit laid partly below and partly above ground.
The pipelines were laid in such a way as to allow further extensions of the plant without any additional costs.
Planned size of the entire complex: 6903m2
Annual return of the entire complex: 3111 MWH
CO2 saving per year: 932,000 kg/year
Solar plant for cooling. The upper floor of the existing one-storey building in Puchstrasse 85 in Graz covers 450 m˛. Office space on the upper floor that had been cooled electrically to date is now to be cooled via solar-powered chilled beams. The cooling station, comprising chiller (nominal capacity 17.5 kW), pump complex, control unit and isolators is installed in container form and set up in front of the building next to the entrance area. The collectors are mounted on the south side of the building and serve at the same time as roofing for the ”Energy Cooling Cabin“.
