Description:  TITLE: Energy Conservation Program: Energy Conservation Standards for 
Manufactured Housing  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Notice of supplemental notice of proposed rulemaking and request for comment  
SUMMARY: The U.S. Department of Energy ("DOE" or "the Department") is publishing a 
supplemental notice of proposed rulemaking ("SNOPR") to establish energy conservation standards 
for manufactured housing pursuant to the Energy Independence and Secu rity Act of 2007. This 
document presents an updated proposal based on the 2021 version of the International Energy 
Conservation Code ("IECC") and comments received during interagency consultation with the U.S.

  manufacturer's retail list price for the manufactured home that would apply the 2021 IECC -based 
standards to manufactur ed homes, except that manufactured homes with a manufacturer's retail 
list price of $55,000 and below would be subject to less stringent building thermal envelope 
requirements based on manufacturer's retail list price. The alternative approach would apply 
standards based on the 2021 IECC to all manufactured homes, with no exceptions for building 
thermal envelope requirements based on manufacturer's retail list price.  
DATES: Meeting: DOE will hold a public meeting via webinar on Tuesday, 28 September 2021, f rom
