It has been a little more than a week since my last posting where I talked about Greenchill and the need to control leaks from systems. The other major driver of a system’s impact on the environment is energy. We at Emerson are always tracking the latest energy efficiency regulations, and 2012 brought several changes for commercial refrigeration equipment including reach-ins, ice machines, walk-ins, supermarket display cases and other stationary commercial refrigeration equipment.
For example, the allowable federal minimum energy efficiency level is actually the same as the voluntary standards set by ENERGY STAR in 2001 for reach-in refrigerators and freezers. The 2010 ENERGY STAR 2.0 standards were baselined to capture the top 25 percent of energy performers. Since 2011 the EPA requires third party lab testing for the ENERGY STAR program. The new LEED for Retail rating system includes equations to calculate levels for prescriptive path LEED efficiency, based on the previous CEE Tier 2 and California Investor Owned Utilities incentive program (CAIOU).
Energy and environmental standards are constantly changing which presents a challenge for refrigeration equipment manufacturers. I would like you all to read more about these and other useful information by clicking on this link below for the Emerson white paper “Status of energy regulations for commercial refrigeration equipment”:
