Federal Register / Vol. 86, No. 158 / Thursday, August 19, 2021 / Rules and Regulations fans are sold without a motor making it impossible to determine whether they would be operated on single-phase or three-phase power and some fans could potentially be operated with either a three-phase or single-phase motor. As such, DOE is not including a phase criterion as part of the definition since it does not sufficiently distinguish a fan as industrial equipment.
Further, while larger fans i.e., fans with higher fan shaft input power are typically used in commercial and industrial applications, some with lower fan shaft input power are also used in smaller commercial and industrial applications. Because nothing would formally prevent the use of a fan with a lower shaft input power in commercial and industrial applications, DOE is not using shaft input power in defining fans and finds the definition as-is will provide sufficient demarcation between industrial equipment and consumer products. DOE may consider fan shaft power when establishing the scope for potential fan test procedures and energy conservation standards.
Commenters raised concerns that including embedded fans would produce overlapping standards and create multiple standard cycles, and questioned how DOE would evaluate performance of embedded fans that work as a component of a system. As discussed, the statutory definition of industrial equipment generally excludes covered products, but does not exclude the component of covered products. EPCA explicitly provides that industrial equipment can be a component of a covered product if the Secretary determines in a rule that such equipment is to a significant extent, distributed in commerce other than as component parts for consumer products and such equipment otherwise meets the definition of industrial equipment.

6312c While some fans that meet the definition of fan as defined in this Final Determination may be component parts of consumer products, not all fans as defined are such. Therefore, whether a fan is embedded is not a criterion that can be reliably used to identify fans.
While some commenters recommended specific exclusions from the fan definition, as stated and discussed in detail in section II.B, DOE
has determined that fans as defined in this final determination and without further exclusions qualify as covered equipment under part A1 of Title III
of EPCA. See 42 U.S.C. 63112A and 42 U.S.C. 6312b This final determination does not establish test procedures or energy conservation standards for fans. In evaluating

potential test procedures and energy conservation standards, DOE will consider the extent to which any such test procedures or standards are appropriate and justified for specific fans.
Based on the foregoing discussion, DOE is establishing the term fan to mean a rotary bladed machine used to convert electrical or mechanical power to air power, with an energy output limited to 25 kilojoule kJ/kilogram kg of air. It consists of an impeller, a shaft, and bearings and/or driver to support the impeller, as well as a structure or housing. A fan may include a transmission, driver, and/or motor controller. DOE is applying the same definition to the term blower.
B. Evaluation of Fans and Blowers as Covered Equipment As stated previously and discussed in detail in the following paragraphs, DOE
has determined that fans i.e., fans and blowers meet the criteria for inclusion as covered equipment. See 42 U.S.C.
63112A and 42 U.S.C. 6312b In response to the April 2020 Notice of Petition, AHRI commented that any final coverage determination that would rely on the analysis performed during the ASRAC process would not be appropriate given concerns related to the fan performance data used which was not certified performance data and was not confirmed to be reflective of fans that are components of HVACR and water heating equipment. Docket No.

The November 2016 NODA analysis included market and technical information to characterize and evaluate the impacts of potential standards on certain embedded fans. 81 FR
75742,75751. As presented and discussed in detail in sections II.B.1, II.B.2, and II.B.4 of this document, DOE
has updated its analysis to account for the findings of the Working Group and additional information collected after the publication of the November 2016
NODA.
As noted, EPCA provides that covered equipment includes any other type of industrial equipment which the Secretary classifies as covered equipment for which the Secretary has determined coverage is necessary to carry out the purpose of Part A1. 42 U.S.C. 63111L.

a type, which 1 in operation consumes, or is designed to consume, energy; 2 to any significant extent, is distributed in commerce for industrial or commercial use; 3 is not a covered product, and 4 for which the Secretary has determined coverage is necessary to carry out the purpose of Part A1. 42 U.S.C. 63112A; 42
U.S.C. 6312b EPCA lists fans i.e., fans and blowers among the equipment that may be industrial equipment. 42 U.S.C.
63112Bii and iii DOE addresses the requirements for determining that fans are industrial equipment and covered equipment in the following paragraphs.
1. Energy Consumption in Operation To qualify as industrial equipment fans and blowers must be of a type which in operation consumes, or is designed to consume, energy. 42 U.S.C.
63112Ai In the 2011 NOPD, DOE used information from the 2009 U.S. Energy Information Administration EIA
Annual Energy Outlook AEO to estimate the total energy consumption of equipment covered under the then proposed definitions of fan and blower in the commercial sector.23 DOE also used the 2009 EIA Manufacturing Energy Consumption Survey to estimate the total electricity consumption of the industrial sector. DOE then used information on the percentage of fan and blower electricity use in industry from an American Council for an Energy-Efficient Economy study 24 to calculate fan and blower electricity use in the industrial sector. DOE estimated that commercial fans and blowers consumed 139,533 million kWh of electricity per year while industrial fans and blowers consumed 90,057
million kWh of electricity per year. 76
FR 37678, 37979.
In response to the 2011 NOPD and the May 2021 RFI, AHRI commented that the energy consumption estimate provided by DOE was based on outdated data and did not account for energy saving measures required by the major energy building codes in the U.S. AHRI
stated that ASHRAE Standard 90.1
2010 Energy Standard for Buildings Except Low-Rise Residential Building 23 DOE used AEOs estimate of total energy consumption in commercial buildings by end use e.g., lighting, cooking, and office equipment and selected ventilation as the representative end use for fans as this equipment is used to provide building ventilation.
