RP-1402 -- Comparison of Vertical Display Cases: Energy and Productivity Impacts of Glass Doors Versus Open Vertical Display Cases PDF

The objective of this project was to compare a typical open refrigerated display case line-up to a typical glass-doored refrigerated display case line-up with the aim of quantifying the following:

• The difference in overall energy consumption for each case type.
• The normalized difference in food product sales for each case type.

Furthermore, the results of this proposed project provide additional information for the ASHRAE Handbook of Refrigeration, Chapter 46, “Retail Food Store Refrigeration and Equipment,” and for the ASHRAE Standard 72-2005, “Method of Testing Commercial Refrigerators and Freezers (ANSI Approved).”
