Weiz-Gleisdorf, Austria
The Weiz-Gleisdorf community is a co-operation between 17 villages and the two cities, Weiz and Gleisdorf in East Styria in the south of Austria. The community has the highest density of solar thermal and photovoltaic systems in Austria. It received two times the European Solar Energy award.
The objective of the co-operation is the promotion and implementation of renewable energy sources, which involves nearly 40,000 inhabitants. This region specifically demonstrates innovative solar thermal systems. These systems involve the installation of solar thermal collectors in 70 private houses for domestic hot water (DHW) and space heating. Most of these systems back up bio-mass boilers, which results in 100% reliance on renewable energy sources (RES). The installation of 60 kW photovoltaic (PV) systems on 20 private households supports the Weiz-Gleisdorf community’s use of RES.
The CONCERTO approach
A 400 kWel bio-gas based co-generation plant for the use of local energy resources in the community of Weiz-Gleisdorf involves the establishment of a bio-fuel infrastructure with pilot plants using plant oil. 30 vehicles are adapted to bio-fuel and put into operation throughout the community.
Use of Renewable Energy Sources
• Biomass
• Solar energy
• Hydropower
• Photovoltaic
Low Carbon Technologies
• Insulation
• District heating
• Optimized lighting
• Boiler burning woodchips
Highlights
The retrofit of the “hostel for pensioners” is a showcase for a multi-family house in Weiz-Gleisdorf.
It includes:
- New glass façade in front of the old façade turning the open balconies into additional living space
- Good insulation
- Modern control engineering
- Controlled ventilation system with 70% heat recovery
- District heat generated from biomass
- 160 m² solar thermal system
