TITLE: Energy Conservation Program: Energy Conservation Standards for Evaporatively -Cooled 
Commercial Package Air Conditioners and Water - Cooled Commercial Package Air Conditioners  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final determination  
SUMMARY: The Energy Policy and Conservation Act ("EPCA"), as amended, prescribes energy 
conservation standards fo r various consumer products and certain commercial and industrial 
equipment, including evaporatively -cooled commercial package air conditioners and water - cooled

  commercial package air conditioners (referred to as evaporatively -cooled commercial unitary ai r 
conditioners ("ECUACs") and water -cooled commercial unitary air conditioners ("WCUACs") in this 
document). EPCA also requires the U.S. Department of Energy ("DOE") to periodically determine 
whether more stringent, amended standards would result in signif icant additional conservation of 
energy, be technologically feasible, and be economically justified. In this final determination, DOE 
has determined that more stringent standards for small (cooling capacity less than 135,000 Btu/h), 
large (cooling capacity  greater than or equal to 135,000 and less than 240,000 Btu/h), and very 
large (cooling capacity greater than or equal to 240,000 and less than 760,000 Btu/h) ECUACs and 
WCUACs would not result in significant additional conservation of energy, and thus has  determined 
that the standards for ECUACs and WCUACs do not need to be amended.  
The effective date of this final determination is 14 July 2021.
