Description:  The U.S. Department of Energy ("DOE") is amending the Federal test procedures for 
air-cooled commercial package air conditioners and heat pumps  with a rated cooling capacity greater 
than or equal to 65,000 Btu/h, evaporatively -cooled commercial package air conditioners, and 
water -cooled commercial package air conditioners to incorporate by reference the latest versions of 
the applicable industry test standards. Specifically, DOE is amending the current test procedure for 
this equipment for measuring the current cooling and heating metrics --integrated energy efficiency

  ratio ("IEER") and coefficient of performance ("COP"), re spectively; and establishing a new test 
procedure for this equipment that adopts two new metrics --integrated ventilation, economizer, and 
cooling ("IVEC") and integrated ventilation and heating efficiency ("IVHE"). Testing to the IVEC and 
IVHE metrics will  not be required until such time as compliance is required with any amended energy 
conservation standard based on the new metrics. Additionally, DOE is amending certain provisions 
of DOE's regulations related to representations and enforcement for the subj ect equipment.  
The effective date of this rule is 5 August 2024. The amendments will be mandatory for testing the 
subject equipment starting 15 May 2025. The incorporation by reference of certain material listed in 
this rule is approved by the Director of the Federal Register on 5 August 2024. The incorporation by 
reference of certain other materials listed in this rule were approved by the Director of the Federal 
Register as of 22 January 2016.
