Commercial Clothes Washers
Manufacturers have been required to comply with the Department of Energy's (DOE) energy conservation standards for commercial clothes washers since 2007. Commercial clothes washers use a water solution of soap, detergent, or both and mechanical movement to clean clothes. Commercial clothes washers are used in commercial settings, multi-family housing, or laundromats. There are two classes of commercial clothes washers: front-loading and top-loading clothes washers.
The current standard will save approximately 0.12 quads of energy and result in approximately $1.1 billion in energy bill savings for products shipped from 2007-2036. The standard will avoid about 6.4 million metric tons of carbon dioxide emissions, equivalent to the annual greenhouse gas emissions of 1.3 million automobiles.
The standard mandatory in 2013 will save approximately 0.1 quads of energy and result in approximately $2.7 billion in energy bill savings for products shipped from 2013-2042. The standard will avoid about 4.3 million metric tons of carbon dioxide emissions, equivalent to the annual greenhouse gas emissions of 843,137 automobiles.

Standards for Commercial Clothes Washers
The following content summarizes the energy factor and water factor requirements and standards for commercial clothes washers. The text is not an official reproduction of the Code of Federal Regulations and should not be used for legal research or citation.
Commercial clothes washers are defined in 10 CFR 431.152. Commercial clothes washers manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations, 10 CFR 431.156. This information is also available in the Electronic Code of Federal Regulations.
Each commercial clothes washer manufactured between January 1, 2007, and January 8, 2013, shall have a modified energy factor of at least 1.26 and a water consumption factor of not more than 9.5.
Each commercial clothes washer manufactured on or after January 8, 2013, shall have a modified energy factor no less than and a water factor no greater than shown in Table 1.

Current Test Procedure
To determine compliance with DOE standards, manufacturers must follow the test procedures specified at 10 CFR 431.154 for commercial clothes washers manufactured or distributed into commerce. These are also in the Electronic Code of Federal Regulations.
The test procedure for commercial clothes washers is required to be the same test procedure established for residential clothes washers. 42 U.S.C. 6314(a)(8)
- Final Rule: Test Procedures, Correction, Federal Register, 77 FR 24341 (April 24, 2012)
- Final Rule: Test Procedures, Correction, Federal Register, 75 FR 20291 (April 4, 2012)
- Final Rule: Test Procedures, Federal Register, 75 FR 13888 (March 7, 2012)
- Docket No. EERE-2010-BT-TP-0021 contains all notices, public comments, public meeting transcripts, and supporting documents.

Test procedure waivers have not been issued for commercial clothes washers.
For information about obtaining test procedure waivers, see 10 CFR 431 subpart V.
DOE's Office of Hearings and Appeals has not authorized exception relief for commercial clothes washers.
For information about obtaining exception relief, see 10 CFR part 1003.
State Exemptions to Federal Pre-emption
DOE has not exempted any states from this energy conservation standard. States may petition DOE to exempt a state regulation from preemption by the Federal energy conservation standard. States may also petition DOE to withdraw such exemptions. For details, see 10 CFR 431, subpart W.
The current energy conservation standards for commercial clothes washers are mandated by Part A–1, the "Certain Industrial Equipment" of Title III of the Energy Policy and Conservation Act (EPCA), as amended. (42 U.S.C. 6311–6317) This equipment is treated as covered equipment under Part A-1. (42 U.S.C. 6311(1)(H))
EPCA requires DOE to establish energy conservation standards for commercial clothes washers if they would be technologically feasible and economically justified. Commercial clothes washers were originally included in the final rule for residential dishwashers, dehumidifiers, cooking products, and commercial clothes washers. However, DOE needed to conduct supplemental rulemaking analyses to complete the rulemaking. As a result, the standards for commercial clothes washers were issued in a separate rulemaking through a supplemental notice of proposed rulemaking and final rule. DOE published the final rule on January 8, 2010.
