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:
