The U.S. Department of Energy on Wednesday adopted new energy efficiency standards for manufactured homes, also known as mobile homes, setting different conservation requirements for single- and multi-section structures to balance up-front affordability against long-term cost savings.
The rules, including new insulation and sealing requirements, could save residents up to $450 annually on utility bills, DOE estimated. About 17 million Americans live in manufactured homes, which are constructed off-site as opposed to traditional stick-built homes.
DOE’s new rules have been criticized by both efficiency advocates, who argue the tiered standard is too lax, and home manufacturers, who say it will drive up costs.
