§ 2795 Efficiency standards

2795. Efficiency standards

Not later than June 1, 2007, the Commissioner shall adopt rules in accordance with the provisions of 3 V.S.A. chapter 25 establishing minimum efficiency standards for the types of new products set forth in section 2794 of this title. The rules shall provide for the following minimum efficiency standards for products sold or installed in this State:

(1) Medium voltage dry-type distribution transformers shall at a minimum meet the efficiency requirements set forth for such transformers in 10 C.F.R. 431.196, as those requirements may be amended from time to time.

(2) Metal halide lamp fixtures designed to be operated with lamps rated greater than or equal to 150 watts but less than or equal to 500 watts shall not contain a probe-start metal halide ballast.

(3)(A) Residential furnaces and residential boilers shall meet or exceed 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 Btus/hour in capacity	83%	2.0%
Oil-fired furnaces > 94,000 Btus/hour in capacity	83%	2.3%
Natural gas-, oil-, and propane-fired not hot water residential boilers	84%	Not applicable
Natural gas-, oil-, and propane-fired steam residential boilers	82%	Not applicable

(B) AFUE shall be measured in accordance with the federal test method for measuring the energy consumption of furnaces and boilers contained in Appendix N to subpart B of part 430, Title 10, Code of Federal Regulations.

(C) The Commissioner may adopt rules to exempt compliance with these residential furnace or residential boiler AFUE standards at any building, site, or location where complying with these standards would be in conflict with any local zoning ordinance, building or plumbing code, or other rule regarding installation and venting of residential boilers or residential furnaces.

(4)(A) Single-voltage external AC to DC power supplies shall meet the energy efficiency requirements of the following table:

Nameplate output power	Minimum efficiency in Active
0 to < 1 watt	0.49* Nameplate Output
≥ 1 watt and < 49 watts	0.09*Ln(Nameplate Output power) + 0.49
> 49 watts	0.84
	Maximum Energy Consumption in No-Load Mode
0 to < watts	0.5 watts
≥ 10 watts and ≤ 250 watts	0.75 watts

* Where Ln (Nameplate Output) = Natural logarithm of the nameplate output expressed in watts.

(B) 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 AC to DC power supplies that are made available by a product manufacturer as accessories, service parts, or spare parts for its products manufactured prior to January 1, 2008 shall be exempt from the requirements of this standard.

(C) For purposes of this subdivision (4), the efficiency of single-voltage external AC to DC power supplies shall be measured in accordance with the test methodology specified by the U.S. Environmental Protection Agency's Energy Star Program, "Test Method for Calculating the Energy Efficiency of Single-Voltage External AC-DC and AC-AC Power Supplies (August 11, 2004)."

(5)(A) 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)(A).

(B) The following types of incandescent reflector lamps are exempt from these requirements:

(i) lamps rated at 50 watts or less of the following types: BR30, ER30, BR40, and ER40;

(ii) lamps rated at 65 watts of the following types: BR30, BR40, and ER40; and

(iii) R20 lamps of 45 watts or less. (Added 2005, No. 152 (Adj. Sess.), 1; amended 2009, No. 159 (Adj. Sess.), 14, eff. June 4, 2010.)
