Proposed Rulemaking for Walk-in Coolers and Freezers
Since EISA was passed January 1, 2009, the U.S. Department of Energy (DOE) has been working to mandate a standardized energy efficiency test for walk-in coolers and freezers. The first step was taken with an informal meeting on February 4, 2009 to discuss comments and suggestions from industry professionals on determining a testing procedure. After nearly a year’s worth of research, DOE has published their proposed testing procedure for walk-in coolers and freezers. A follow-up meeting was scheduled to discuss these proposed rulings, but due to winter weather the meeting was canceled and has not been rescheduled at this time.
In accordance with section 312 of the Energy Independence and Security Act (EISA), DOE published a Notice of Proposed Rulemaking (NOPR) for the test procedure on walk-in coolers and freezers. The NOPR is the first published document for the test procedure rulemaking process for walk-ins. DOE proposes the procedures explained in the NOPR be used to test walk-in equipment. Once performance standards are accepted, manufacturers will be required to use the accepted test to determine compliance and for all representations regarding the energy use of the product.
DOE proposes to adopt a test procedure that contains two separate testing methods; one for the insulated box and the other for the refrigeration equipment. Each of the two components, the insulated box and the refrigeration system, will be tested separately. The manufacturer will be responsible for testing their product respectively and must provide compliance with all testing standards.
