2 Based on Rating Temperature -15°F and Operating Temperature ≤ -5°F.
(C) Commercial refrigeration equipment with two or more compartments.
For commercial refrigeration equipment with two or more compartments, (i.e., hybrid refrigerators, hybrid freezers, hybrid refrigerator-freezers, and non-hybrid refrigerator-freezers), the maximum daily energy consumption (MDEC) for each model shall be the sum of the MDEC values for all of its compartments. For each compartment, measure the TDA or volume of that compartment, and determine the appropriate equipment class based on that compartment's equipment family, condensing unit configuration, and designed operating temperature. The MDEC limit for each compartment shall be the calculated value obtained by entering that compartment's TDA or volume into the standard equation in Table A-4, Table A-5, or Table A-6 of this Article for that compartment's equipment class. Measure the calculated daily energy consumption (CDEC) or total daily energy consumption (TDEC) for the entire case as described in 10 C.F.R. section 431.66(d)(2)(i) through(iii), except that where measurements and calculations reference ARI Standard 1200-2006, AHRI Standard 1200 (I-P)-2010 shall be used.
(D) Wedge Cases. For remote-condensing and self-contained wedge cases, measure the CDEC or TDEC according to the AHRI Standard 1200 (I-P)-2010 test procedure incorporated by reference in 10 C.F.R. section 431.63. For wedge cases in equipment classes for which a volume metric is used, the MDEC shall be the amount derived from the appropriate standards equation in Table A-4, Table A-5, or Table A-6 of this Article. For wedge cases of equipment classes for which a TDA metric is used, the MDEC for each model shall be the amount derived by incorporating into the standards equation in Table A-4, Table A-5, or Table A-6 of this Article for the appropriate equipment class a value for the TDA that is the product of:
- 1. The vertical height of the air-curtain (or glass in a transparent door), and
2. The largest overall width of the case, when viewed from the front.
Exception to Section 1605.1(a)(2) of this Article: The standards shown in section 1605.1(a)(2) of this Article do not apply to salad bars, buffet tables, chef bases, or griddle stands.
(3) Automatic Commercial Ice Makers.

(2) Central Furnaces and Boilers. Central furnaces and boilers manufactured on or after the effective dates shown shall meet all applicable requirements shown in Tables E-3, E-4, E-5, and E-6.
(A) Automatic Means for Adjusting Water Temperature. The automatic means for adjusting the temperature design, shown as footnote 2 in Table E-3 immediately above, means:
- 1. In General. The manufacturer shall equip each gas, oil, and electric hot water boiler (other than a boiler equipped with a tankless domestic water heating coil) with automatic means for adjusting the temperature of the water supplied by the boiler to ensure that an incremental change in inferred heat load produces a corresponding incremental change in the temperature of water supplied.
- 2. Single Input Rate. For a boiler that fires at one input rate, the requirements of this subparagraph may be satisfied by providing an automatic means that allows the burner or heating element to fire only when the means has determined that the inferred heat load cannot be met by the residual heat of the water in the system.
- 3. No Inferred Heat Load. When there is no inferred heat load with respect to a hot water boiler, the automatic means described in subsections 1605.1(e)(2)(A)1. and 1605.1(e)(2)(A)2. of this Article shall limit the temperature of the water in the boiler to not more than 140°F.
- 4. Operation. A boiler described in subsections 1605.1(e)(2)(A)1. or 1605.1(e)(2)(A)2. of this Article shall be operable only when the automatic means described in subsections 1605.1(e)(2)(A)1., 1605.1(e)(2)(A)2., and 1605.1(e)(2)(A)3. of this Article is installed.
(B) EXCEPTION to section 1605.1(e)(2) of this Article: A boiler that is manufactured to operate without any need for electricity or any electric connection, electric gauges, electric pumps, electric wires, or electric devices shall not be required to meet the efficiency standards or design standard that take effect for models manufactured on or after September 1, 2012. Boilers described in this EXCEPTION are required to meet the efficiency standards in effect prior to September 1, 2012, as applicable.

(6) Determinations of Efficiency. For purposes of determining the required minimum nominal full load efficiency of an electric motor that has a horsepower or kilowatt rating between two horsepower or two kilowatt ratings shown in Tables S-1, S-2, or S-3, or of determining the required minimum average full load efficiency of a small electric motor that has a horsepower or kilowatt rating between two horsepower or kilowatt ratings shown in Table S-4, each such motor shall be deemed to have a listed horsepower or kilowatt rating determined as follows:
- (A) A horsepower at or above the midpoint between the two consecutive horsepower ratings shall be rounded up to the higher of the two horsepower ratings;
- (B) A horsepower below the midpoint between the two consecutive horsepower ratings shall be rounded down to the lower of the two horsepower ratings; or
- (C) A kilowatt rating shall be directly converted from kilowatts to horsepower using the formula, 1 kilowatt = (1/0.746) horsepower, without calculating beyond three significant decimal places, and the resulting horsepower shall be rounded in accordance with sections 1605.1(s)(6)(A) or 1605.1(s)(6)(B) of this Article, whichever applies.
(7) Compressors.
(A) Federally Regulated Compressors. Federally regulated compressors manufactured on or after January 10, 2025, shall meet the applicable energy efficiency standards in Table S-5.

Where V1 is the full-load actual volume flow rate of the compressor, in cubic feet per minute, as determined in accordance with the test procedure in section 1604(s) of this Article.
† For “fixed-speed compressor” equipment classes, the relevant Package Isentropic Efficiency is Full-load Package Isentropic Efficiency. For “Variable-speed compressor” equipment classes, the relevant Package Isentropic Efficiency is Part-load Package Isentropic Efficiency. Both Full- and Part-Load Package Isentropic Efficiency are determined in accordance with the test procedure in section 1604(s) of this Article.
