Une étude récente établit que 40% de l'énergie utilisée par les supermarchés allemands est consacrée aux rayons frais et surgelés.
 According to a recent survey, the average energy used to provide cooling to chilled and frozen displays represents 40% of the total energy demand of German supermarkets. The energy percentage for air conditioning is 8% and respectively 30 and 20% for the heating and lighting.

Since 2014, the energy cost has fallen by 6% through the implementation of energy efficiency measures such as the use of low energy LED lighting, energy monitoring and efficient refrigeration systems with heat recovery. Transcritical CO2 systems are used in 50% of new and refurbished supermarkets surveyed.
