Design Implications: US Department of Energy’s New Efficiency Requirements in 2023
The U.S. Department of Energy (DOE) will enact new nationwide efficiency requirements for HVAC equipment on January 1, 2023. As part of the DOE’s goal to reduce overall energy consumption, the rating procedure (i.e., the performance calculation) has become more stringent and complex. Excluding split system heat pumps, split system air conditioners that do not meet these new ratings will not be installable after January 1, 2023. Equipment currently in production is being phased out in anticipation of this new..
