Making and Keeping the Connection: A Model of Success
There are several fan regulations being drafted by the California Energy Commission (CEC) and the U.S. Department of Energy that may have very serious impacts on the HVAC industry. This session will address and provide up-to-date decisions and details.
With the DOE, in July 2022, the U.S. Department of Energy (DOE) issued final rules on two regulations affecting manufacturers of large-diameter (greater than 7 ft.) ceiling fans (LDCF) sold in the United States and Canada. The regulations impact how LDCF are tested and how compliance data are reported, as well as determine stand-by power requirements.
Secondly, in June 2022 the DOE began a proposed rulemaking process that would establish fan energy index (FEI) as the efficiency metric for commercial and industrial fans and blowers. This new test standard/requirement would apply to most types of commercial and industrial fans with at least 1 hp fan shaft power or at least 1 kW electrical power but not more than 150 air horsepower. Covered fans include circulating fans that are not ceiling fans (all sizes) and commercial and industrial fans between 1 hp and 150 hp (~1 kW to 110 kW). Excluded from the regulation are ceiling fans, air-curtain units, crossflow fans, induced-flow fans, jet fans, and many types of safety fans, such as those for high-temperature application. Exceptions include: (1) radial housed unshrouded fans with a diameter less than 30 in. or a blade width less than 3 in., (2) safety fans, (3) induced-flow fans, (4) jet fans, and (5) cross-flow fans. The exclusion of fans that create 30-in.-wg or greater vacuum is recommended. With an expectation that testing phase would be complete by the end of 2022, this new rule would be in effect in early 2023. Notably, this test procedure would apply to all fans sold in the United States, regardless of where they are manufactured. Through reciprocity agreements, the test procedure could apply to fans sold in Canada as well.
Finally, in California, the CEC Title 20
