Description:  TITLE: Energy Conservation Program: Energy Conservation Standards for Direct 
Expansion -Dedicated Outdoor Air Systems  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: In this final rule, DOE is establishing energy conservation standards for direct expansion -
dedicated outdoor air systems ("DX - DOASes") that are of equivalent stringency as the minimum 
levels specified in the most recent publication of the American Society of Heating, Refrigerating and 
Air-Conditioning Engineers ("ASHRAE") Standard 90.1 "Energy Standard for Buildings Except Low -
Rise Residential  Buildings" ("ASHRAE 90.1 -2019") when tested pursuant to the DOE test procedure

  for DX -DOASes --which incorporates by reference the most recent applicable industry standard for 
this equipment. DOE has determined that it lacks clear and convincing evidence t o adopt standards 
more stringent than the levels specified in ASHRAE 90.1 -2019.  
DATES: The effective date of this rule is 3 January 2023. Compliance with the standards established 
for DX -DOASes in this final rule is required on and after 1 May 2024.  
Curren t Popular ASHRAE Standards and Guidelines, including ASHRAE 90.1 -2019, are available for
