Dutch retail chain Spar has partnered with the Salzburg Technical College in Austria to develop a self-sufficient supermarket, as part of the college’s Smart Building study programme.
Spar Austria has provided energy data and retail planning knowledge from its existing Eurospar store in Straßwalchen.
Students visited the store to learn about the building’s existing technologies and energy systems, which were then incorporated into project plans for the new supermarket.
The chosen project proposed that the self-sufficient supermarket be made from re-usable parts.
It featured the use of solar energy-based Rawlemon solar crystal balls, which would be integrated into the building's façade to produce energy for the store's lighting, heating, ovens and refrigeration systems.
Spar Austria energy and technology construction head Gerald Geiger said: “For many years now, we have used a comprehensive sustainability concept for the construction and conversion of our stores.
