Grocery stores are energy intensive. Profit margins of 2-3% are offset by energy costs of 4-5%, of which a significant part can be saved. Given the low profit margins in the food sector, energy efficient management is of great economic interest.

A substantial amount of energy in grocery stores is needed for food cooling and air conditioning. There are various possibilities to save energy, CO₂ and money in an economically attractive way with an amortization of two to four years.
