(2) Commercial clothes washers shall meet the requirements shown in Table P-4 of § 1605.3 of the California Code of Regulations, Title 20: Division 2, Chapter 4, Article 4: Appliance Efficiency Regulations in effect on December 15, 2004.

(3) Commercial pre-rinse spray valves shall have a flow rate equal to or less than one and six-tenths gallons (1.6 gals.) per minute.

(6) Illuminated exit signs shall have an input power demand of five watts (5 W) or less per illuminated face.

(7) Large packaged air-conditioning equipment shall meet a minimum energy efficiency ratio of:

(i) Ten (10.0) for air conditioning without an integrated heating component or with electric resistance heating integrated into the unit;

(ii) Nine and eight tenths (9.8) for air conditioning with heating other than electric resistance integrated into the unit;

(iii) Nine and five tenths (9.5) for air conditioning with heating other than electric resistance integrated heating component or with electric resistance heating integrated into the unit;

(iv) Nine and three tenths (9.3) for air-conditioning heat pump equipment with heating other than electric resistance integrated into the unit. Large packaged air-conditioning heat pumps shall meet a minimum coefficient of performance in the heating mode of three and two tenths (3.2) (measured at a high temperature rating of forty-seven (47) degrees F db).

(8) Low-voltage dry-type distribution transformers shall meet the Class 1 efficiency levels for low-voltage distribution transformers specified in Table 4-2 of the “Guide for Determining Energy Efficiency for Distribution Transformers” published by the National Electrical Manufacturers Association (NEMA Standard TP-1-2002).

(9) Metal-halide lamp fixtures that operate in a vertical position and are designed to be operated with lamps rated greater than or equal to one hundred fifty watts (150 W) but less than or equal to five hundred watts (500 W) shall not contain a probe-start metal-halide lamp ballast.

(10) Single-voltage external AC to DC power supplies shall meet the tier-one energy-efficiency requirements shown in Table U-1 of § 1605.3 of the California Code of Regulations, Title 20: Division 2, Chapter 4, Article 4: Appliance Efficiency Regulations as adopted on December 15, 2004. This standard applies to single-voltage AC to DC power supplies that are sold individually and to those that are sold as a component of or in conjunction with another product. Single-voltage external AC to DC power supplies that are made available by a product manufacturer as service parts or spare parts for its products manufactured prior to January 1, 2008, shall be exempt from this provision.

(11) Torchieres shall not use more than one hundred ninety watts (190 W). A torchiere shall be deemed to use more than one hundred ninety watts (190 W) if any commercially available lamp or combination of lamps can be inserted in its socket(s) and cause the torchiere to draw more than one hundred ninety watts (190 W) when operated at full brightness.

(12) Traffic signal modules shall meet the product specification of the “Energy Star Program Requirements for Traffic Signals” developed by the U.S. Environmental Protection Agency that took effect in February 2001 and shall be installed with compatible, electronically-connected signal-control interface devices and conflict-monitoring systems.

(13) Unit heaters shall be equipped with an intermittent ignition device and shall have either power venting or an automatic flue damper.

(b) Not later than June 1, 2007, the commission, in consultation with the state building commissioner and the chief of energy and community services, shall adopt regulations, in accordance with the provisions of chapter 35 of title 42, establishing minimum efficiency standards for the types of new products set forth in § 39-27-4(b). The regulations shall provide for the following minimum efficiency standards.

(1) Bottle-type water dispensers designed for dispensing both hot and cold water shall not have standby energy consumption greater than one and two-tenths kilowatt-hours (1.2 KWh) per day.

(2) Commercial hot food holding cabinets shall have a maximum idle energy rate of forty watts (40 W) per cubic foot of interior volume.

(3)(i) Residential furnaces and residential boilers shall comply with the following Annual Fuel Utilization Efficiency (AFUE) and electricity ratio values:

Product Type Minimum AFUE Maximum
electricity ratio
Natural gas and propane-fired furnaces 90% 2.0%
Oil-fired furnaces>94,000    
Btu/hour in capacity 83% 2.0%
Oil-fired furnaces>94,000    
Btu/hour in capacity 83% 2.3%
Natural gas and oil, and propane-fired hot water residential boilers 84% Not applicable
Natural gas, oil, and propane-fired steam residential boilers 82% Not applicable

(ii) The chief of energy and community services shall adopt rules to provide for exemptions from compliance with the foregoing residential furnace or residential boiler AFUE standards at any building, site, or location where complying with the standards would be in conflict with any local zoning ordinance, fire code, building or plumbing code, or other rule regarding installation and venting of residential furnaces or residential boilers.

(iii) The provisions of subsection (b) shall be effective upon determination by the chief of energy and community services that the same or substantial corresponding standards have been enacted in two (2) New England states.

(4)(i) State-regulated incandescent reflector lamps shall meet the minimum average lamp efficacy requirements for federally-regulated incandescent reflector lamps contained in 42 U.S.C. § 6295(i)(1)(B).

(B) Lamps, rated at sixty-five watts (65 W) of the following types: BR30, BR40, and ER40; and

(C) R20 lamps of forty-five watts (45 W) or less.

(5)(i) Walk-in refrigerators and walk-in freezers with the applicable motor types shown in the table below shall include the required components shown.
