energy use
(kWh/100 lbs.) | Maximum condenser
water use
(gallons/100 lbs. ice) |
| Ice-making head | water | <500 | 7.80 - .0055H | 200 - .022H |
| >=500<1436 | 5.58 - .0011H | 200 - .022H |
| >=1436 | 4.0 | 200 - .022H |
| Ice-making head | air | 450 | 10.26 - .0086H | Not applicable |
| >=450 | 6.89 - .0011H | Not applicable |
| Remote condensing but not remote compressor | air | <1000 | 8.85 - .0038 | Not applicable |
| >=1000 | 5.10 | Not applicable |
| Remote condensing and remote compressor | air | <934 | 8.85 - .0038H | Not applicable |
| >=934 | 5.3 | Not applicable |
| Self-contained models | water | <200 | 11.40 - .0190H | 191 - .0315H |
| >=200 | 7.60 | 191 - .0315H |
| Self-contained models | air | <175 | 18.0 - .0469H | Not applicable |
| >=175 | 9.80 | Not applicable |
| Where H= harvest rate in pounds per twenty-four hours which must be reported within 5% of the tested value. "Maximum water use" applies only to water used for the condenser. |
(b) For purposes of this section, automatic commercial ice cube machines shall be tested in accordance with ARI 810-2003 test method as published by the air-conditioning and refrigeration institute. Ice-making heads include all automatic commercial ice cube machines that are not split system ice makers or self-contained models as defined in ARI 810-2003.
(2) Commercial clothes washers must have a minimum modified energy factor of 1.26. For the purposes of this section, capacity and modified energy factor are defined and measured in accordance with the current federal test method for clothes washers as found at 10 C.F.R. Sec. 430.23.
(3) Commercial prerinse spray valves must have a flow rate equal to or less than 1.6 gallons per minute when measured in accordance with the American society for testing and materials' "Standard Test Method for Prerinse Spray Valves," ASTM F2324-03.
(4)(a) Commercial refrigerators and freezers must meet the applicable requirements listed in the following table:
| Equipment Type | Doors | Maximum Daily Energy Consumption (kWh) |
| Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are refrigerators | Solid | 0.10V+ 2.04 |
| Transparent | 0.12V+ 3.34 |
| Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are "pulldown" refrigerators | Transparent | .126V+ 3.51 |
| Reach-in cabinets, pass-through cabinets, and roll-in or roll-through cabinets that are freezers | Solid | 0.40V+ 1.38 |
| Transparent | 0.75V+ 4.10 |
Reach-in cabinets that are refrigerator-freezers
with an AV of 5.19 or higher
| Solid
| 0.27AV - 0.71
|
kWh= kilowatt hours
V= total volume (ft3)
AV= adjusted volume= [1.63 x freezer volume (ft3)]+ refrigerator volume (ft3) |
(b) For purposes of this section, "pulldown" designates products designed to take a fully stocked refrigerator with beverages at 90 degrees F and cool those beverages to a stable temperature of 38 degrees F within 12 hours or less. Daily energy consumption shall be measured in accordance with the American national standards institute/American society of heating, refrigerating and air-conditioning engineers test method 117-2002, except that the back-loading doors of pass-through and roll-through refrigerators and freezers must remain closed throughout the test, and except that the controls of all appliances must be adjusted to obtain the following product temperatures.
| Product or compartment type | Integrated average product temperature in degrees Fahrenheit |
| Refrigerator | 38+ 2 |
| Freezer | 0+ 2 |
(5) 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 lamp ballast.
(6)(a) Single-voltage external AC to DC power supplies shall meet the requirements in the following table:
| Nameplate output | Minimum Efficiency in Active Mode |
| < 1 Watt | 0.49 * Nameplate Output |
| > or= 1 Watt and < or= 49 Watts | 0.09 * Ln (Nameplate Output)+ 0.49 |
| > 49 Watts | 0.84 |
| Maximum Energy Consumption in No-Load Mode |
| < 10 Watts | 0.5 Watts |
> or= 10 Watts and < or= 250 Watts
| 0.75 Watts |
| Where Ln (Nameplate Output) - Natural Logarithm of the nameplate output expressed in Watts |
(b) For the purposes of this section, efficiency of single-voltage external AC to DC power supplies shall be measured in accordance with the United States environmental protection agency's "Test Method for Calculating the Energy Efficiency of Single-Voltage External AC to DC and AC to AC Power Supplies," by Ecos Consulting and Power Electronics Application Center, dated August 11, 2004.
(7)(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. Sec. 6295(i)(l)(A).
(b) The following types of incandescent lamps are exempt from these requirements:
(i) Lamps rated at fifty watts or less of the following types: BR 30, ER 30, BR 40, and ER 40;
(ii) Lamps rated at sixty-five watts of the following types: BR 30, BR 40, and ER 40; and
(iii) R 20 lamps of forty-five watts or less.
(8) Unit heaters must be equipped with intermittent ignition devices and must have either power venting or an automatic flue damper.
