Energy Conservation Standards for Manufactured Housing

The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) is preparing an environmental impact statement (EIS) for proposed energy conservation standards for manufactured housing.


The Energy Independence and Security Act of 2007 (EISA) directs DOE to establish energy conservation standards for manufactured housing based on the most recent version of the International Energy Conservation Code (IECC). EERE is currently planning to issue a Supplemental Notice of Proposed Rulemaking (SNOPR) (on or before August 16, 2021) for publication in the Federal Register that will propose energy conservation standards for manufactured housing based on the 2021 IECC.

DOE will be proposing energy efficiency standards for manufactured homes that 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. DOE is also considering an action alternative that uses a tiered approach to address affordability and cost-effectiveness concerns with respect to energy cost savings and the cost of efficiency improvements relative to the retail price of manufactured housing.

DOE will prepare an environmental impact statement (EIS) to evaluate the potential impacts to the human environment associated with this proposed action (energy conservation standards for manufactured housing) and alternatives, including a no action alternative. DOE anticipates evaluating potential impacts related to: (1) indoor air quality and human health; (2) outdoor emissions of air pollutants and greenhouse gases; (3) energy consumption; (4) socioeconomics; (5) environmental justice; and (6) climate change.

Public Comment Opportunity

There are no public comment opportunities at this time.

EIS Scoping Period

DOE sought input from all interested stakeholders on the appropriate scope of the EIS. All parties were invited to provide comments on the scope of the EIS for 30 days after the Notice of Intent (NOI) to prepare an EIS was published in the Federal Register. Comments on the scope of the EIS were accepted from July 7, 2021 through August 6, 2021.

Comments directly relevant to the scope of the EIS were invited, in accordance with the National Environmental Policy Act (NEPA) process. These comments might relate to potential environmental impacts, reasonable alternatives to the proposed energy conservation standards, and mitigation measures to consider in the EIS.

(Note: Comments were not taken on the proposed rule for energy conservation standards as part of the EIS scoping process, because those inputs are sought under a separate process. After the proposed rule is published in the Federal Register (expected on or after August 16, 2021), DOE will hold one public webinar, and there will be a 60-day public comment period during which DOE will invite public comments on the proposed rule.)

In defining the scope of the EIS, DOE is considering all scoping comments submitted online or postmarked by August 6, 2021. Comments received after this date will be considered to the extent practicable.

EIS Public Scoping Meetings

In July 2021, DOE held two public scoping meetings at which DOE presented preliminary information on the scope of the EIS and invited oral comments. The recordings of these meetings are available on YouTube via the links below.

How the EIS Scoping Comments Will Be Used

The draft EIS (which will be available on this website when completed) will include a summary of the alternatives, information, and analyses submitted by commenters during the scoping process for consideration by DOE in developing the EIS.
