A modular home is a prefabricated home that is made of multiple modules or sections that are manufactured and substantially assembled in a manufacturing plant. These pre–built sections are transported to the building site and constructed by a builder to meet all applicable building codes for site–built homes.
A home earns the ENERGY STAR by meeting strict program requirements for energy efficiency set by the U.S. EPA. The program requirements applied to modular homes are the same as those applied to site–built homes. However, modular homes designed and produced in the plant to meet the ENERGY STAR program requirements are only "ENERGY STAR certified" after they are inspected and verified on site and receive the blue ENERGY STAR Certified Home label. Homes cannot be marketed or promoted as "ENERGY STAR labeled" or "ENERGY STAR certified" until the site verification process has been completed by a third–party verifier.
There are two ways a modular home can meet these program requirements and earn the ENERGY STAR:
Version # | Applicable to Homes with the Following Sales Date | Version Description |
---|---|---|
Version 2.5 |
On or after 10/01/2011 and before 01/01/2014 |
Version 2.5: Core Version 3 energy efficiency measures with Air Barriers and Air Sealing sections of Thermal Enclosure System Rater Checklist; Other checklists completed but not enforced |
Version 3 |
On or after 01/01/2014 | Version 3: Core Version 3 energy efficiency measures with all checklists completed and enforced |
The following verification procedures can be followed for modular homes to earn the ENERGY STAR label. These procedures include three main elements:
To produce modules for homes that, when constructed, can earn the ENERGY STAR, a manufacturing plant must first demonstrate to the satisfaction of a qualified and Quality Assurance Provider (QAP)–approved third–party consultant that it has the ability to consistently produce homes that comply with the ENERGY STAR requirements with respect to all work conducted in the plant. This results in the plant being certified by the third–party consultant to produce modules that can earn the ENERGY STAR. All work of the plant is conducted under the oversight of the third–party consultant who is a specialist in factory building with expertise in energy efficient construction.
To become certified the plant must develop procedures that address:
Compliance with ENERGY STAR requirements for each home must be verified both in the plant and at the site following procedures that are established by a QAP. These procedures must address home compliance both in the plant and at the site as follows:
ENERGY STAR provides its active partners the opportunity to utilize the ENERGY STAR brand in promoting homes that earn the ENERGY STAR label. Modular manufacturing plant and builder partners must adhere to ENERGY STAR's Brand Brand Book when promoting ENERGY STAR certified modular homes. These guidelines describe how the ENERGY STAR name and marks may be used in promotional materials. In addition, ENERGY STAR distributed a letter (PDF, 656 KB) and a quick logo–use reference guide (PDF, 2.0 MB) to all ENERGY STAR modular plant partners that provides clarification on how plants can use the ENERGY STAR brand.
These requirements apply to manufactured homes, defined as homes built in a factory that are subject to the federal Manufactured Home Construction and Safety Standards (commonly referred to as the HUD Code) contained in 24 CFR 3280.

Plant Certification
To earn the ENERGY STAR label, a manufactured home must meet all applicable program requirements and be produced in a plant that is certified by one of the following EPA-recognized Quality Assurance Providers (QAP’s).
The plant certification process, as well as oversight and enforcement of all quality assurance requirements related to designing, producing, and installing ENERGY STAR certified manufactured homes, is the responsibility of the QAP. Once certified, the plant must follow the QAP’s guidelines for ongoing production, installation, and certification of homes to maintain its plant certification status.
This table contains all implementation timelines applicable on or after June 1, 2020. Implementation timelines applicable prior to this date can be obtained by contacting energystarhomes@energystar.gov.

EPA allows existing homes to earn the ENERGY STAR when all requirements of the ENERGY STAR Certified Homes program are met. EPA does recognize that some of the current program requirements present unique challenges for existing homes, even those undergoing a gut rehabilitation.
To help mitigate these challenges, EPA has developed alternative compliance options for existing homes. These alternative options are for specific items on the ENERGY STAR Certified Homes Inspection Checklists and have been incorporated directly into the Inspection Checklists with the release of Revision 07. These alternatives are available for use and are listed in the Policy Record. See Recent Policy Changes and Clarifications.
While EPA does not mandate the scope of work for existing home projects, it has identified key components that may be needed to meet the ENERGY STAR Certified Homes program requirements. These include the following:
EPA acknowledges that additional alternatives, increased flexibility, and alternative assessment protocols would expand the number of homes able to earn the ENERGY STAR. EPA is committed to including additional alternatives as they become available so that more homes may earn the ENERGY STAR label without sacrificing performance.
EPA receivedcomments (PDF, 337 KB) from partners and other stakeholders regarding the Proposed Alternative Compliance Pathways for Homes Undergoing a Gut Rehabilitation (PDF, 589 KB). Note: These were the proposed alternatives and not all alternatives were adopted. For the available alternatives, please see the most recent Policy Record found here: Recent Policy Changes and Clarifications

Homes and apartments are eligible to participate in the ENERGY STAR NextGen Certified Homes and Apartments program if they meet the eligibility requirements of the ENERGY STAR Single-Family New Homes (SFNH) National or California Program Requirements, or the ENERGY STAR Multifamily New Construction (MFNC) National or California Program Requirements.
