The grocer has agreed an initial £44m deal with Zumtobel for supply of the luminaires. Ever since they opened, the two LED-lit eco-stores have been under ultra-close monitoring.
‘It soon emerged that lighting is second only to the HVAC system in terms of energy consumption,’ Spar director Hans Reisch told Lux magazine. ‘That’s why the board decided to make a “green investment” in our future.
‘The budgeted savings of 80 and 50 tonnes of CO2 a year per store are looking perfectly feasible, although it remains to be seen what the summer months will bring before we draw any conclusions about full-year operations across all four seasons,’ said Reisch.
The LED-based continuous row lighting system – Tecton from Zumtobel – installed at the two climate-friendly supermarkets in Austria not only provides better quality of light but also uses half the lighting energy of an average supermarket.
