Getting Started with ENERGY STAR Certified Manufactured Homes

ENERGY STAR’s requirements for manufactured homes afford the manufactured housing industry a unique opportunity to extend the advantages of controlled-environment factory production to include exemplary energy performance. A manufactured home earns the ENERGY STAR by meeting strict program requirements for energy efficiency set by the U.S. EPA. Currently, these requirements differ from the requirements for site-built homes.

Manufactured homes are ENERGY STAR certified only after they are inspected and verified on site as having met all ENERGY STAR requirements and have received the blue ENERGY STAR Certified Home label. Homes cannot be marketed or promoted as "ENERGY STAR labeled" or "ENERGY STAR certified" until this site verification process has been completed by a qualified third-party verifier.

There are two ways a manufactured home can earn the ENERGY STAR certification and label:

  1. Each home is rated by a third-party Home Energy Rater (or equivalent), similar to the verification process applied to site-built homes. The Home Energy Rater must coordinate with the plant and the installer to verify those ENERGY STAR-related features of the home that are installed both in the plant and on-site.
  2. A manufactured home that is eligible to earn the ENERGY STAR label is produced within a plant that is under the oversight of an EPA-recognized Quality Assurance Provider (QAP). This involves a plant certification process to certify that a plant has incorporated ENERGY STAR requirements into its in-plant inspection procedures and can consistently produce homes that can earn the ENERGY STAR, as well as an on-site inspection process where a third-party consultant visually checks that all ENERGY STAR requirements have been met. 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.

The Systems Building Research Alliance (SBRA) has been approved by EPA as a national QAP for ENERGY STAR certified manufactured homes. For SBRA’s compliance procedures go to www.research-alliance.org. Exit ENERGY STAR The Northwest Energy Efficient Manufactured Housing Program (NEEM) Exit ENERGY STAR serves as a QAP for ENERGY STAR manufactured homes produced by plants within the Pacific Northwest.

Guidelines for Retailers, Installers, HVAC Contractors

Retailers and installers (including HVAC contractors) of manufactured homes play an important role in educating homebuyers about the benefits of ENERGY STAR certified manufactured homes and assuring that these homes are properly installed. SBRA has developed a booklet titled ENERGY STAR Certified Manufactured Homes: Guide for Retailers Exit ENERGY STAR (with instructions for installers and HVAC contractors) that explains how retailers can partner with ENERGY STAR and benefit from marketing these homes to homebuyers. It describes the roles and responsibilities of retailers, installers, and HVAC contractors and lists marketing and sales tools available to retailers.

Cooling Equipment Sizing Charts

Updated guidelines PDF (3.83MB) for right-sizing cooling equipment for manufactured homes is now available. These guidelines were developed to eliminate the problem of choosing equipment that is oversized and that contributes to higher than necessary energy consumption. The guidelines consist of nine maps covering the continental U.S. plus a Sizing Table containing recommended cooling equipment sizes (in tons). The maps are divided into counties. Contiguous counties with the same sizing recommendations are combined into Sizing Groups.

Tax Credits for ENERGY STAR Certified Manufactured Homes

The federal tax credit for producers of ENERGY STAR certified manufactured homes expired on December 31, 2016. For information on federal income tax credits for energy efficiency.

Partner Recognition Opportunities

As part of the plant certification process described above, manufacturing plants must become ENERGY STAR partners. Active partners gain access to partner-only resources such as the ENERGY STAR logo that can be used in promoting ENERGY STAR certified homes in accordance with the ENERGY STAR Brand Book. Active partners are also listed on the ENERGY STAR Partner Locator. Active plant partners that meet or exceed a threshold number of ENERGY STAR certified homes produced are eligible for an ENERGY STAR Certified Homes Market Leader Award. There is no application necessary to be eligible for this award. Plant recipients are selected each year by EPA based strictly on the number of ENERGY STAR certified manufactured homes they have produced during the calendar year. For more information about the ENERGY STAR Certified Homes Market Leader Award contact energystarhomes@energystar.gov.
