Refrigeration is one of the main drivers in supermarkets’ energy consumption, almost 50 % of the total.

The Climate KIC Start-up ChillServices has developed an innovative plug-on technology and service to increase the energy efficiency within supermarkets. ChillServices piloted its technology in 50 supermarkets (1000 cabinets) in cooperation with the most energy efficient supermarket chain in Germany, the REWE group, in 2017. The project realized a decreased electricity consumption for doored refrigerated display cabinet (RDC) of 3% as well as reducing temperature related maintenance needs by 48% on average, resulting in a return of investment of the innovation of 2,5 years. This equals approximately 300 kWh of less energy consumption per cabinet and 10 less maintenance visits per market, resulting in roughly 5 tons CO2 per market per year.
