Summary

The U.S. Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy (EERE) has prepared an environmental impact statement (EIS) for proposed energy conservation standards for manufactured housing (DOE/EIS-0550). The Notice of Availability (NOA) for the final EIS will be published in the Federal Register on April 8, 2022.

The Energy Independence and Security Act of 2007 directs DOE to establish energy conservation standards for manufactured housing based on the most recent version of the International Energy Conservation Code (IECC). DOE has prepared an EIS (DOE/EIS-0550) to provide information to the public and to inform the final rulemaking for the proposed energy conservation standards for manufactured housing. The EIS evaluates the potential impacts to the human environment associated with the proposed energy conservation standards for manufactured housing.

DOE’s proposed action in the EIS is to establish energy conservation standards for manufactured housing. The proposed energy conservation standards are based on the 2021 IECC and relate to the building thermal envelope; air sealing; installation of insulation; duct sealing; heating, ventilation, and air conditioning (HVAC); service hot water systems; mechanical ventilation fan efficacy; and heating and cooling equipment sizing. The EIS evaluates alternative approaches to establishing energy conservation standards for manufactured housing (including energy conservation standards that are tiered based on the manufacturers retails list price, standards that are tiered based on size of the manufactured home, and untiered energy conservation standards) and a no action alternative.

The EIS presents analyses of potential impacts related to: (1) energy resources; (2) air resources (including greenhouse gases, climate change, ambient air quality and indoor air quality); (3) health and safety; (4) socioeconomics; and (5) environmental justice.

Additional information about the EIS, including the Notice of Intent, slides presented at the public scoping meetings, the draft EIS, recordings of the draft EIS public meetings and the final EIS can be accessed on the EIS website at https://ecs-mh.evs.anl.gov/.
