Medium-temperature display cases consume roughly 18% of the total electricity use of a supermarket. Open, multi-deck meat/dairy/deli cases can contribute up to 25% of refrigeration energy consumption.

In addition to this significant contribution to energy use, meat/dairy/deli cases are required to maintain a desirable meat temperature. Fresh meat, deli, and dairy products, according to Food and Drug Administration (FDA) classification, are required to be stored at less than 41°F at all times, including post-defrost periods, at any location within the case.
