EPA Webinar on Light Commercial HVAC Equipment

In response to the U.S. federal increase in minimum energy performance standards, scheduled to go into effect January 1, 2023, the EPA announced it is introducing Version 4.0 Draft 1 specification for review to replace Version 3.1 specification for light commercial HVAC products given that the energy efficiency requirements under DOE Appendix M1 are more stringent than what is contained in 3.1.

EPA plans to host a webinar on November 16 from 12:00 p.m. to 2:00 p.m. to discuss the Draft 1 specification.

According to the announcement, Version 4.0 proposes the following changes:

  • Changing the scope of 3.1 by bringing “units with a cooling capacity below 65,000 Btu/h into the scope of … Version 4.0 specification after they were previously removed from scope for Version 3.0.”
  • Introducing “higher IEER and EER requirements for Central Air Conditioner (CAC) products and higher IEER, EER and COP at 47°F requirements for Air-Source Heat Pump (ASHP) products.”
  • A cold climate recognition by “recognizing ASHP and VRF mini-split products meeting cold climate performance requirements with an “ENERGY STAR Cold Climate” label.”
  • A proposal that “the gas furnace included in a Gas/Electric Packaged Product must have 3 or more capacity stages.”

Members interested in attending the webinar can RSVP here.

Members can provide written comments for EPA consideration to LCHVAC@energystar.gov by December 13, 2021.

All comments will be posted to the ENERGY STAR LCHVAC Product Development website unless the submitter requests otherwise.
