Electric Motors and Air-Conditioning Maintenance under 42 U.S.C. § 8259b(d) says that in the case of electric motors of 1 to 500 horsepower, agencies are to select only premium efficient motors that meet a standard designated by the U.S. Department of Energy. Agencies are also encouraged to take actions to maximize the efficiency of air-conditioning and refrigeration equipment.
(1) In the case of electric motors of 1 to 500 horsepower, agencies shall select only premium efficient motors that meet a standard designated by the Secretary. The Secretary shall designate such a standard not later than 120 days after August 8, 2005, after considering the recommendations of associated electric motor manufacturers and energy efficiency groups.
(2) All Federal agencies are encouraged to take actions to maximize the efficiency of air-conditioning and refrigeration equipment, including appropriate cleaning and maintenance, including the use of any system treatment or additive that will reduce the electricity consumed by air-conditioning and refrigeration equipment. Any such treatment or additive must be—
(A) determined by the Secretary to be effective in increasing the efficiency of air conditioning and refrigeration equipment without having an adverse impact on air conditioning performance (including cooling capacity) or equipment useful life;
(B) determined by the Administrator of the Environmental Protection Agency to be environmentally safe; and
(C) shown to increase seasonal energy efficiency ratio (SEER) or energy efficiency ratio (EER) when tested by the National Institute of Standards and Technology according to DOE test procedures without causing any adverse impact on the system, system components, the refrigerant or lubricant, or other materials in the system. Results of testing described in subparagraph (C) shall be published in the Federal Register for public review and comment. For purposes of this section, a hardware device or primary refrigerant shall not be considered an additive.
