Glass Doored versus Open Vertical Display Cases: Energy and Sales

The objective of this project was to compare the energy consumption and food product sales of an open refrigerated
display case line-up to a glass-doored refrigerated display case line-up. It was found that ‘doored versus
open’ had no effect on product sales and that per unit length of case line-up, the open display case line-up consumed approximately 1.3 times more energy than the doored display case line-up.
