This study determined the hourly energy and demand impacts of three common commercial refrigeration retrofit measures commonly installed through energy efficiency programs in New England, New York and the midAtlantic: Electronically commutated motors (ECMs) on evaporator fans in coolers and freezers; Evaporator fan controls; and Anti-sweat door heater controls. These measures reliably produce energy and demand savings in commercial programs, yet little or no evaluations using empirical evidence exists outside of this study. It included a variety of manufacturers, products and types of technologies. The report provides impacts for each measure type, including ISO-NE summer and winter and PJM summer demand savings, as well as impact parameters that can be used to update Technical Reference Manuals.
