Energy Conservation Program: Energy 

Conservation Standards for Fans and 

Blowers 

AGENCY: Office of Energy Efficiency and 

Renewable Energy, Department of 

Energy. 

ACTION: Request for information. 

SUMMARY: The U.S. Department of 

Energy (‘‘DOE’’ or ‘‘the Department’’) is 

evaluating potential energy conservation 

standards for fans and blowers, 

including air circulating fans. Through 

this request for information (‘‘RFI’’), 

DOE seeks data and information to help 

determine whether potential energy 

conservation standards for fans and 

blowers, including air circulating fans, 

would result in standards that are 

technologically feasible and 

economically justified while producing 

significant conservation of energy. DOE 

welcomes written comments from the 

public on any subject within the scope 

of this document (including those topics 

not specifically raised in this RFI), as 

well as the submission of data and other 

relevant information. 

DATES: Written comments and 

information are requested and will be 

accepted on or before March 10, 2022. 

ADDRESSES: Interested persons are 

encouraged to submit comments using 

the Federal eRulemaking Portal at 

www.regulations.gov. Follow the 

instructions for submitting comments. 

Alternatively, interested persons may 

submit comments, identified by docket

I. Introduction 

A. Authority and Background 

The Energy Policy and Conservation 

Act, as amended (‘‘EPCA’’),1 authorizes 

DOE to regulate the energy efficiency of 

a number of consumer products and 

certain industrial equipment. (42 U.S.C. 

6291–6317) Title III, Part C 2 of EPCA, 

added by Public Law 95–619, Title IV, 

section 441(a) (42 U.S.C. 6311–6317 as 

codified), established the Energy 

Conservation Program for Certain 

Industrial Equipment, which sets forth a 

variety of provisions designed to 

improve energy efficiency. 

EPCA specifies a list of equipment 

that constitutes covered equipment 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 7049 

3 ‘‘Covered equipment’’ means one of the 

following types of industrial equipment: Electric 

motors and pumps; small commercial package air 

conditioning and heating equipment; large 

commercial package air conditioning and heating 

equipment; very large commercial package air 

conditioning and heating equipment; commercial 

refrigerators, freezers, and refrigerator-freezers; 

automatic commercial ice makers; walk-in coolers 

and walk-in freezers; commercial clothes washers; 

packaged terminal air-conditioners and packaged 

terminal heat pumps; warm air furnaces and 

packaged boilers; and storage water heaters, 

instantaneous water heaters, and unfired hot water 

storage tanks. (42 U.S.C. 6311(1)(A)–(K)) 

4 DOE notes that distribution for residential use 

does not preclude coverage as covered equipment, 

so long as the equipment is of a type that is also 

distributed in commerce for industrial and 

commercial use. 

5All documentation from the Working Group 

meetings may be found in Docket No. EERE–2013– 

BT–STD–0006) at www.regulations.gov/docket/ 

EERE-2013-BT-STD-0006/document. 

6At the beginning of the negotiated rulemaking 

process, the Working Group defined that before any 

vote could occur, the Working Group must establish 

a quorum of at least 20 of the 25 members and 

defined consensus as an agreement with less than 

4 negative votes. Twenty voting members of the 

Working Group were present for this vote. Two 

members (Air-Conditioning, Heating, and 

Refrigeration Institute and Ingersoll Rand/Trane) 

voted no on the term sheet. 

7 In addition to the 27 recommendations, there 

were five recommendations that did not receive a 

consensus vote. Recommendations 28, 29, 30, 31, 

and 32 are included in Appendix F of the term 

sheet and were not approved by ASRAC. 

8See Recommendation 2 of the term sheet. 

(hereafter referred to as ‘‘covered 

equipment’’).3 EPCA also provides that 

‘‘covered equipment’’ includes any 

other type of industrial equipment for 

which the Secretary of Energy 

(‘‘Secretary’’) determines inclusion is 

necessary to carry out the purpose of 

Part A–1. (42 U.S.C. 6311(1)(L); 42 

U.S.C. 6312(b)) EPCA specifies the types 

of industrial equipment that can be 

classified as covered in addition to the 

equipment enumerated in 42 U.S.C. 

6311(1) This industrial equipment 

includes fans and blowers. (42 U.S.C. 

6311(2)(B)(ii) and (iii)) Additionally, 

industrial equipment must be of a type 

that consumes, or is designed to 

consume, energy in operation; is 

distributed in commerce for industrial 

or commercial use 4; and is not a 

covered product as defined in 42 U.S.C. 

6291(a)(2) other than a component of a 

covered product with respect to which 

there is in effect a determination under 

42 U.S.C. 6312(c). (42 U.S.C. 6311(2)(A)) 

On August 19, 2021, DOE published a 

final determination that the inclusion of 

fans and blowers as covered equipment 

was necessary to carry out the purpose 

of Part A–1 and classified fans and 

blowers as covered equipment. 86 FR 

46579, 46588. Air circulating fans are a 

class of fans and blowers. 

The energy conservation program 

under EPCA consists essentially of four 

parts: (1) Testing, (2) labeling, (3) 

Federal energy conservation standards, 

and (4) certification and enforcement 

procedures. Relevant provisions of 

EPCA include definitions (42 U.S.C. 

6311), test procedures (42 U.S.C. 6314), 

labeling provisions (42 U.S.C. 6315), 

energy conservation standards (42 

U.S.C. 6313), and the authority to 

require information and reports from 

manufacturers. (42 U.S.C. 6316; 42 

U.S.C. 6296) 

Federal energy efficiency 

requirements for covered equipment 

established under EPCA generally 

supersede State laws and regulations 

concerning energy conservation testing, 

labeling, and standards. (42 U.S.C. 

6316(a) and (b); 42 U.S.C. 6297) DOE 

may, however, grant waivers of Federal 

preemption for particular State laws or 

regulations, in accordance with the 

procedures and other provisions of 

EPCA. (42 U.S.C. 6316(b)(2)(D)) 

In proposing new standards, DOE 

must evaluate that proposal against the 

criteria of 42 U.S.C. 6295(o), as 

described in section I.C of this 

document, and follow the rulemaking 

procedures set out in 42 U.S.C. 6295(p). 

(42 U.S.C. 6316(a)) DOE is publishing 

this RFI consistent with its obligations 

in EPCA. 

B. Rulemaking History 

On June 28, 2011, DOE published a 

notice of proposed determination of 

coverage proposing to determine that 

fans, blowers, and fume hoods qualify 

as covered equipment. 76 FR 37678. 

DOE noted that there are no statutory 

definitions for ‘‘fan,’’ ‘‘blower,’’ or 

‘‘fume hood,’’ and presented definitions 

for consideration. 76 FR 37678, 37679. 

DOE subsequently published a 

framework document on February 1, 

2013 detailing the analytical approach 

for developing potential energy 

conservation standards for commercial 

and industrial fans and blowers should 

the Secretary classify such equipment as 

covered equipment (‘‘Framework 

Document’’). 78 FR 7306. In the 

Framework Document, DOE determined 

that it lacks authority to establish energy 

conservation standards for fume hoods 

because fume hoods are not listed as a 

type of equipment for which DOE could 

establish standards. (Docket EERE– 

2013–BT–STD–0006, No. 1 at p. 15) 

DOE acknowledged that the fan, which 

provides ventilation for the fume hood, 

consumes the largest portion of energy 

within the fume hood system, and that 

DOE planned to cover all commercial 

and industrial fan types, which includes 

fans used to ventilate fume hoods. Id. 

On December 10, 2014, DOE 

published a notice of data availability 

that presented a provisional analysis 

estimating the economic impacts and 

energy savings from potential energy 

conservation standards for certain fans 

and blowers. This analysis did not 

include air circulating fans. 79 FR 

73246. 

On April 1, 2015, DOE published a 

notice of intent to establish an 

Appliance Standards and Rulemaking 

Federal Advisory Committee 

(‘‘ASRAC’’) Working Group for fans 

(hereafter referred to as the ‘‘Working 

Group’’). 80 FR 17359. 

The Working Group commenced 

negotiations at an open meeting on May 

18, 2015 and held 16 meetings and three 

webinars to discuss scope, metrics, test 

procedures, and standard levels for fans 

and blowers.5 The Working Group 

concluded its negotiations on 

September 3, 2015, and, by consensus 

vote,6 approved a term sheet containing 

27 recommendations related to scope, 

test procedure and energy conservation 

standards (‘‘term sheet’’).7 See Docket 

No. EERE–2013–BT–STD–0006, No. 

179. ASRAC approved the term sheet on 

September 24, 2015. The Working 

Group term sheet recommended the 

exclusion of circulating fans.8

On May 10, 2021, DOE published a 

request for information requesting 

comments on a potential fan or blower 

definition. 86 FR 24752 (‘‘May 2021 

RFI’’). On August 19, 2021, DOE 

published in the Federal Register a final 

coverage determination classifying fans 

and blowers as covered equipment 

(‘‘August 2021 Final Coverage 

Determination’’). 86 FR 46579. 

To date, DOE has not proposed test 

procedures or energy conservation 

standards for fans and blowers, 

including air circulating fans. 

C. Rulemaking Process 

DOE must follow specific statutory 

criteria for prescribing new or amended 

standards for covered equipment. EPCA 

requires that any new or amended 

energy conservation standard prescribed 

by the Secretary of Energy (‘‘Secretary’’) 

be designed to achieve the maximum 

improvement in energy or water 

efficiency that is technologically 

feasible and economically justified. (42 

U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A)) 

Furthermore, DOE may not adopt any 

standard that would not result in the 

significant conservation of energy. (42 

U.S.C. 6316(a); 42 U.S.C. 6295(o)(3)) 

The significance of energy savings 

offered by a new or amended energy 

conservation standard cannot be 

determined without knowledge of the 

specific circumstances surrounding a

9See 86 FR 70892, 70901 (Dec. 13, 2021). 

given rulemaking.9 For example, the 

United States has now rejoined the Paris 

Agreement on February 19, 2021. As 

part of that agreement, the United States 

has committed to reducing the GHG 

emissions in order to limit the rise in 

mean global temperature. As such, 

energy savings that reduce GHG 

emission have taken on greater 

importance. Additionally, some covered 

products and equipment have most of 

their energy consumption occur during 

periods of peak energy demand. The 

impacts of these products on the energy 

infrastructure can be more pronounced 

than products with relatively constant 

demand. In evaluating the significance 

of energy savings, DOE considers 

differences in primary energy and full 

fuel cycle (‘‘FFC’’) effects for different 

covered products and equipment when 

determining whether energy savings are 

significant. Primary energy and FFC 

effects include the energy consumed in 

electricity production (depending on 

load shape), in distribution and 

transmission, and in extracting, 

processing, and transporting primary 

fuels (i.e., coal, natural gas, petroleum 

fuels), and thus present a more complete 

picture of the impacts of energy 

conservation standards. Accordingly, 

DOE evaluates the significance of energy 

savings on a case-by-case basis. 

To determine whether a standard is 

economically justified, EPCA requires 

that DOE determine whether the 

benefits of the standard exceed its 

burdens by considering, to the greatest 

extent practicable, the following seven 

factors: 

(1) The economic impact of the 

standard on the manufacturers and 

consumers of the affected products; 

(2) The savings in operating costs 

throughout the estimated average life of 

the product compared to any increases 

in the initial cost, or maintenance 

expenses; 

(3) The total projected amount of 

energy and water (if applicable) savings 

likely to result directly from the 

standard; 

(4) Any lessening of the utility or the 

performance of the products likely to 

result from the standard; 

(5) The impact of any lessening of 

competition, as determined in writing 

by the Attorney General, that is likely to 

result from the standard; 

(6) The need for national energy and 

water conservation; and 

(7) Other factors the Secretary 

considers relevant. 

(42 U.S.C. 6316(a); 42 U.S.C. 

6295(o)(2)(B)(i)(I)–(VII)) 

DOE fulfills these and other 

applicable requirements by conducting 

a series of analyses throughout the 

rulemaking process. Table I.1 shows the 

individual analyses that are performed 

to satisfy each of the requirements 

within EPCA.

As detailed throughout this RFI, DOE 

is publishing this document seeking 

input and data from interested parties to 

aid in the development of the technical 

analyses on which DOE will ultimately 

rely to determine whether (and if so, 

how) to establish the standards for air 

circulating fans. 

D. Deviation From Appendix A 

In accordance with section 3(a) of 10 

CFR part 430, subpart C, appendix A, 

DOE notes that it is deviating from that 

appendix’s provision requiring a 75-day 

comment period for all pre-NOPR 

standards documents. 10 CFR part 430, 

subpart C, appendix A, section 6(d)(2). 

DOE is opting to deviate from this step 

because DOE believes a 30-day 

comment period is sufficient given the 

substantial stakeholder engagement to 

date, as discussed in section I.B of this 

document. Further, the 30-day comment 

period will allow DOE to review 

comments received in response to this 

RFI to inform the scope of equipment 

considered in evaluating potential 

energy conservation standards, in 

particular whether air circulating fans 

should be included as part of that 

evaluation. DOE believes that the test 

procedure request for information on air 

circulating fan heads provided early 

notice that the Department is interested 

in evaluating potential energy savings 

for this equipment. 

II. Request for Information 

In the following sections, DOE has 

identified a variety of issues on which 

it seeks input to aid in the development 

of the technical and economic analyses 

regarding whether standards for air 

circulating fans may be warranted. DOE 

also welcomes comments on other 

issues relevant to its analysis that may 

not specifically be identified in this 

document. 

A. Scope 

On October 1, 2021, DOE published a 

request for information pertaining to 

potential test procedures for fans and 

blowers (‘‘October 2021 TP RFI’’). 86 FR 

54412. As part of the October 2021 TP 

RFI, DOE discussed potential scope and 

definitions for air circulating fans, 

which include air circulating fan heads, 

personnel coolers, box fans, and table 

fans. 86 FR 54412, 54414–54415. DOE is 

considering including air circulating 

fans in its analysis of potential energy 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 7051 

10ANSI/AMCA 230–15 is available at the AMCA 

website at www.amca.org/publish/publicationsand-standards/amca-standards/amca-standard- 230-15-laboratory-methods-of-testing-aircirculating-fans-for-rating-and-certification.html. 

conservation standards for fans and 

blowers. 

B. Market and Technology Assessment 

The market and technology 

assessment that DOE routinely conducts 

when analyzing the impacts of a 

potential new or amended energy 

conservation standard provides 

information about the air circulating fan 

industry that will be used in DOE’s 

analysis throughout the rulemaking 

process. DOE uses qualitative and 

quantitative information to characterize 

the structure of the industry and market. 

DOE identifies manufacturers, estimates 

market shares and trends, addresses 

regulatory and non-regulatory initiatives 

intended to improve energy efficiency 

or reduce energy consumption, and 

explores the potential for efficiency 

improvements in the design and 

manufacturing of air circulating fans. 

DOE also reviews product literature, 

industry publications, and company 

websites. Additionally, DOE considers 

conducting interviews with 

manufacturers to improve its assessment 

of the market and to better understand 

available air circulating fan 

technologies. 

1. Equipment Classes 

When evaluating and establishing 

energy conservation standards, DOE 

may divide covered equipment into 

equipment classes by the type of energy 

used, by capacity, or by other 

performance-related features that may 

justify a different standard. (42 U.S.C. 

6316(a); 42 U.S.C. 6295(q)(1)) In making 

a determination whether a performancerelated feature justifies a different 

standard, DOE must consider such 

factors as the utility of the feature to the 

consumer and other factors DOE deems 

appropriate. Id. ANSI/AMCA Standard 

230–15 ‘‘Laboratory Methods of Testing 

Air Circulating Fans for Rating and 

Certification’’ (‘‘AMCA 230–15’’) 10 is 

the industry test procedure for air 

circulating fans, which includes air 

circulating fan heads, personnel coolers, 

box fans, and table fans. Section 5.1. of 

AMCA 230–15 defines an air circulating 

fan as ‘‘a non-ducted fan used for the 

general circulation of air within a 

confined space’’ and provides 

additional definitions for air circulating 

fan head (section 5.1.1), ceiling fan 

(section 5.1.2), personnel cooler (section 

5.1.3), box fan (section 5.1.4), and table 

fan (section 5.1.5). 

Table II.2 lists the four categories of 

air circulating fans as defined in in 

AMCA 230–15. DOE is evaluating 

whether to consider these four 

categories of air circulating fans 

separately, or if they should be 

considered as a single equipment 

category. 

TABLE II.2—DEFINITIONS OF AIR CIRCULATING FAN CATEGORIES

Category Definition according to AMCA 230–15 

Air Circulating Fan Head ...... An assembly consisting of a motor, impeller, and guard for mounting on a pedestal having a base and column, 

wall mount bracket, ceiling mount bracket, I-beam bracket, or other commonly accepted mounting means. 

Box Fan ................................ A fan used in an office or residential application and having the motor and impeller enclosed in an approximately 

square box frame having a handle. 

Personnel Cooler ................. A fan used in shops, factories, etc. Generally supplied with wheels or casters on the housing or frame to aid in 

portability and with motor and impeller enclosed in a common guard and shroud. 

Table Fan ............................. A fan intended for use on a desk, table, or countertop. The fan may also be provided with the means for mounting to a wall. 

DOE’s evaluation of product literature 

indicates that drum fans, barrel fans, 

and portable blowers are also sold as air 

circulating fans. DOE has tentatively 

included these fans under the definition 

of personnel coolers in Table II.2 of this 

RFI. 

DOE suggested a potential definition 

for air circulating fan heads in the 

October 2021 RFI, including that these 

fans are fans are designed for directional 

airflow. DOE is interested in 

understanding the type(s) of airflow 

typically associated with personnel 

coolers, box fans, and table fans. DOE 

will consider any feedback and 

comments on the flow and potential 

definitions for personnel cooler, box 

fan, and table fan in the test procedure 

docket (EERE–2021–BT–TP–0021). 

Issue 1: DOE requests comment on 

whether it should consider air 

circulating fan heads, personnel coolers, 

box fans, and table fans as separate 

categories or whether some or all of 

these four categories should be grouped 

together when evaluating potential 

energy conservation standards for fans. 

Specifically, DOE seeks information and 

data on whether these four fan 

categories have unique features or 

applications that warrant separate 

consideration from each other or 

whether any of them are so similar that 

they should be grouped together. DOE 

also requests feedback on whether there 

are any air circulating fans that it should 

include in its analysis that are not listed 

in Table II.2 of this RFI. 

Issue 2: DOE requests information on 

whether each of the four categories of 

air circulating fans shown in Table II.2 

of this RFI provide general circulation of 

air, directional airflow, or some other 

type of airflow. 

Issue 3: DOE requests feedback on 

whether air circulating fan heads, 

personnel coolers, box fans, or table fans 

could be delineated into separate 

equipment classes based on diameter, 

operating speed, efficiency, or utility. If 

so, DOE seeks feedback on what those 

equipment classes would be for the 

particular air circulating fan categories 

and what features distinguish them from 

one another. 

Issue 4: DOE requests feedback on 

whether the definition of personnel 

coolers in Table II.2 of this RFI is 

sufficiently describes drum fans, barrel 

fans, and portable blower fans. If not, 

DOE requests information and data 

showing any differences in size, 

operating speed, efficiency, or utility 

between personnel coolers, drum fans, 

barrel fans, and portable blower fans. 

2. Technology Assessment 

In analyzing the feasibility of 

potential new energy conservation 

standards, DOE uses information about 

existing and past technology options 

and prototype designs to help identify 

technologies that manufacturers could 

use to meet and/or exceed a given 

energy conservation standard level 

under consideration. In consultation 

with interested parties, DOE intends to 

develop a list of technologies to 

consider in its analysis of air circulating 

fans. 

DOE reviewed manufacturer catalogs, 

recent trade publications, and technical

options that could improve the 

efficiency of air circulating fans. A list 

of potential technology options for air 

circulating fans is shown in Table II.3 of 

this document. 

TABLE II.3—POTENTIAL TECHNOLOGY OPTIONS FOR AIR CIRCULATING FANS

Technology option Description 

Improved aerodynamic design.Improving the aerodynamics of fan components that are placed in the flow of air can improve efficiency. This includes the motor housing and the rear and front fan guards but does not include blade design. 

Blade shape ......................... Adjusting the amount or direction of the curvature of the blades can improve efficiency. Airfoil blades, in particular, may offer better efficiency than other blade shapes.11

More efficient motors ........... Three-phase AC Induction motors and Brushless DC motors have improved efficiencies compared to Singlephase AC Induction motors. 

Three-phase induction motors can produce higher torque than single-phase induction motors and can therefore 

turn the fan shaft more efficiently. They also have less thermal energy losses than single-phase induction motors. 

Brushless DC motors are a type of permanent magnet synchronous motor, which are more efficient than induction motors due to the lack of rotor losses. 

Material selection ................. Different materials, such as aluminum, plastic, steel, and fiberglass can be used for fan blade impellers and may 

improve fan efficiency. 

Variable speed drives 

(VSDs).

VSDs allow control over fan speed for fans sold with a motor. The fan speed can be optimized to maximize efficiency for fans that experience variable loads. 

Issue 5: DOE requests information on 

how the technologies listed in Table II.3 

of this document may impact the 

efficiency of air circulating fans. 

Specifically, DOE seeks data showing 

how one or more of the technology 

options listed in Table II.3 of this RFI 

improves air circulating fan efficiency. 

Additionally, DOE requests comment on 

whether the technology options listed in 

Table II.3 of this document apply 

equally to the different categories of air 

circulating fans (i.e., air circulating fan 

heads, personnel fans, box fans, and 

table fans). If not, DOE requests 

information on why they cannot be 

applied equally for the different classes. 

Issue 6: DOE requests data on the 

impact of curved blades and airfoil 

blades on the efficiency of air 

circulating fans. Additionally, DOE 

requests feedback on whether any blade 

shapes not listed in Table II.3 are 

typically used for air circulating fans. 

DOE also requests data on the 

percentage of shipments for each 

category of air circulating fan (i.e., air 

circulating fan heads, personnel coolers, 

box fans, and table fans) with curved 

blades, airfoil blades, or other blade 

types. 

Issue 7: DOE requests data on the 

percentage of air circulating fans sold 

with a motor. For those fans sold with 

a motor, DOE seeks data on the 

percentage of these fans currently sold 

with a variable speed drive. 

Additionally, DOE requests information 

on whether a higher percentage of 

certain categories of air circulating fans 

(i.e., air circulating fan heads, personnel 

fans, box fans, and table fans) are sold 

with motors and/or variable speed 

drives than other types. 

Issue 8: DOE requests feedback on the 

efficiency impact of the blade materials 

listed in Table II.3 of this RFI for air 

circulating fans. Specifically, DOE 

requests data on the percentage of air 

circulating fan shipments that utilize 

aluminum, plastic, steel, or fiberglass 

for the design and manufacture of fan 

blades. Additionally, DOE seeks 

information on whether any materials 

not listed in Table II.3 of this RFI are 

used, and if so, the percentage of fans 

sold with these other materials. 

Issue 9: DOE seeks comment on 

technology options not listed in Table 

II.3 of this document that it should 

consider for inclusion in its analysis of 

air circulating fans, or for specific 

categories of air circulating fans (i.e., air 

circulating fan heads, personnel fans, 

box fans, and table fans) and if these 

technologies may impact product 

features or consumer utility. 

Issue 10: DOE requests feedback on 

the order in which manufacturers would 

implement the technology options listed 

in Table II.3 of this RFI to increase the 

energy efficiency of air circulating fans. 

Additionally, DOE solicits feedback on 

whether the order in which the 

technology options listed in Table II.3 of 

this document might change for the 

different categories of air circulating 

fans (i.e., air circulating fan heads, 

personnel fans, box fans, and table fans). 

DOE is also interested in understanding 

whether the increased energy efficiency 

from any combination of the technology 

options in Table II.3 of this RFI would 

result in design changes that would not 

otherwise occur. Finally, DOE requests 

information on how incorporating any 

of the technology options listed in Table 

II.3 of this RFI may impact other fan 

functions or attributes in response to 

consumer demand. 

C. Screening Analysis 

The purpose of the screening analysis 

is to evaluate the technologies that 

improve energy efficiency to determine 

which technologies will be eliminated 

from further consideration and which 

will be passed to the engineering 

analysis for further consideration. 

DOE determines whether to eliminate 

certain technology options from further 

consideration based on the following 

criteria: 

(1) Technological feasibility. DOE will 

only consider technologies that are 

incorporated in commercial products or 

in working prototypes. 

(2) Practicability to manufacture, 

install, and service. If DOE determines 

that mass production of a technology in 

commercial products and reliable 

installation and servicing of the 

technology could not be achieved on the 

scale necessary to serve the relevant 

market at the time of the compliance 

date of the standard, DOE will eliminate 

that technology from further 

consideration. 

(3) Impacts on product utility or 

product availability. If DOE determines 

a technology has a significant adverse 

impact on the utility of the product to 

significant subgroups of consumers, or 

results in the unavailability of any 

covered product type with performance 

characteristics (including reliability), 

features, sizes, capacities, and volumes 

that are substantially the same as 

products generally available in the 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 7053 

United States at the time, DOE will 

eliminate it from further consideration. 

(4) Adverse impacts on health or 

safety. If DOE determines that a 

technology will have significant adverse 

impacts on health or safety, DOE will 

eliminate that technology from 

consideration. 

(5) Unique-Pathway Proprietary 

Technologies. If a design option utilizes 

proprietary technology that represents a 

unique pathway to achieving a given 

efficiency level, DOE will eliminate that 

technology from consideration due to 

the potential for monopolistic concerns. 

10 CFR 431.4; 10 CFR part 430, subpart 

C, appendix A, sections 6(b)(3) and 7(b) 

Technology options identified in the 

technology assessment are evaluated 

against these criteria using DOE 

analyses and inputs from interested 

parties (e.g., manufacturers, trade 

organizations, and energy efficiency 

advocates). Technologies that pass 

through the screening analysis are 

referred to as ‘‘design options’’ in the 

engineering analysis. As described 

above, DOE eliminates from 

consideration any technology options 

that fail to meet one or more of the five 

criteria. 

Issue 11: DOE requests feedback on 

what impact, if any, the five screening 

criteria described in this section would 

have on each of the technology options 

listed in Table II.3 of this document 

with respect to air circulating fans. 

Similarly, DOE seeks information 

regarding how these same criteria would 

affect any other technology options not 

already identified in this document with 

respect to their potential use in air 

circulating fans. 

Issue 12: DOE seeks information on 

the technology options listed in Table 

II.3 of this RFI for air circulating fans 

regarding their market adoption, costs, 

and any potential issues with 

incorporating them into products (e.g., 

impacts on consumer utility, potential 

safety concerns, manufacturing, or 

production challenges, etc.). 

Additionally, DOE requests comment on 

if there are any differences in the market 

adoption, costs, safety, or utility of the 

technology options in Table II.3 of this 

RFI for the different categories of air 

circulating fans (i.e., air circulating fan 

heads, personnel fans, box fans, and 

table fans). 

D. Engineering Analysis 

The purpose of the engineering 

analysis is to establish the relationship 

between the efficiency and cost of air 

circulating fans. There are two elements 

to consider in the engineering analysis: 

The selection of efficiency levels to 

analyze (i.e., the ‘‘efficiency analysis’’) 

and the determination of product cost at 

each efficiency level (i.e., the ‘‘cost 

analysis’’). In determining the 

performance of higher-efficiency 

products, DOE considers technologies 

and design option combinations not 

eliminated by the screening analysis. 

For each equipment class, DOE 

estimates the baseline cost, as well as 

the incremental cost for the equipment 

at efficiency levels above the baseline. 

The output of the engineering analysis 

is a set of cost-efficiency ‘‘curves’’ that 

are used in downstream analyses (i.e., 

the life-cycle cost (‘‘LCC’’ and payback 

period (‘‘PBP’’) analyses and the 

national impacts analysis (‘‘NIA’’)). 

1. Efficiency Analysis 

DOE typically uses one of two 

approaches to develop energy efficiency 

levels for the engineering analysis: (1) 

Relying on observed efficiency levels in 

the market (i.e., the efficiency level 

approach) or (2) determining the 

incremental efficiency improvements 

associated with incorporating specific 

design options to a baseline model (i.e., 

the design-option approach). Using the 

efficiency-level approach, the efficiency 

levels established for the analysis are 

determined based on the market 

distribution of existing products (in 

other words, based on the range of 

efficiencies and efficiency level 

‘‘clusters’’ that already exist on the 

market). Using the design option 

approach, the efficiency levels 

established for the analysis are 

determined through detailed 

engineering calculations and/or 

computer simulations of the efficiency 

improvements from implementing 

specific design options that have been 

identified in the technology assessment. 

DOE may also rely on a combination of 

these two approaches. For example, the 

efficiency-level approach (based on 

actual products on the market) may be 

extended using the design option 

approach to interpolate to define ‘‘gap 

fill’’ levels (to bridge large gaps between 

other identified efficiency levels) and/or 

to extrapolate to the max-tech level 

(particularly in cases where the maxtech level exceeds the maximum 

efficiency level currently available on 

the market). 

a. Baseline Efficiency 

For each evaluated equipment class, 

DOE selects a baseline model as a 

reference point against which any 

changes resulting from new or amended 

energy conservation standards can be 

measured. The baseline model in each 

equipment class represents the 

characteristics of common or typical 

equipment in that class. Air circulating 

fans do not currently have established 

energy conservation standards, so DOE 

cannot use certification values or 

current minimum energy conservation 

standards to determine a baseline for air 

circulating fans. Instead, DOE plans to 

use performance data from air 

circulating fans currently on the market 

to establish a baseline. 

Issue 13: DOE requests efficiency data 

measured according to the ACMA 230– 

15 test procedure to characterize the 

baseline efficiency level of air 

circulating fans. Alternatively, DOE 

requests feedback on how it can best 

determine appropriate baseline 

efficiency levels for air circulating fans. 

b. Maximum Available Efficiency 

As part of DOE’s analysis, the 

maximum available efficiency level is 

the highest efficiency unit currently 

available on the market. DOE also 

defines a ‘‘max-tech’’ efficiency level to 

represent the theoretical maximum 

possible efficiency if all available design 

options are incorporated in a model. In 

applying these design options, DOE 

would only include those that are 

compatible with each other and that 

when combined, would represent the 

theoretical maximum possible 

efficiency. In many cases, the max-tech 

efficiency level is not commercially 

available because it is not economically 

feasible. 

Issue 14: DOE seeks input on the 

maximum available efficiencies for air 

circulating fans and whether the 

maximum available efficiencies are 

appropriate and technologically feasible 

for consideration as possible energy 

conservation standards for air 

circulating fans. Additionally, DOE 

requests comment on whether the 

maximum available efficiencies for air 

circulating fan categories (i.e., air 

circulating fan heads, personnel coolers, 

box fans, and table fans) are comparable, 

or whether there are significant 

differences in maximum efficiencies 

between categories. 

Issue 15: DOE seeks feedback on what 

design options would be incorporated at 

a max-tech efficiency level for all 

categories of air circulating fans, and the 

efficiencies associated with those levels. 

As part of this request, DOE also seeks 

information as to whether there are 

limitations on the use of certain 

combinations of design options. 

c. Differences Between Air Circulating 

Fans and General Fans 

DOE is aware that the design and use 

of air circulating fans is different from 

the fans and blowers evaluated by the 

Working Group. For instance, air 


khammond on DSKJM1Z7X2PROD with PROPOSALS
7054 Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 

circulating fans use a total pressure 

basis rather than a static pressure basis. 

Additionally, Section 5.1.1 of AMCA 

214–21 uses a target of 0.66 when 

establishing the FEI based on the total 

pressure of the air circulating fan under 

test. 

Issue 16: DOE requests comment on 

additional differences between air 

circulating fans and general fans that it 

should include in its analysis. 

2. Cost Analysis 

The cost analysis portion of the 

engineering analysis is conducted using 

one or a combination of cost 

approaches. The selection of cost 

approach depends on a suite of factors, 

including availability and reliability of 

public information, characteristics of 

the regulated product, and the 

availability and timeliness of 

purchasing the product on the market. 

The cost approaches are summarized as 

follows: 

• Physical teardowns: Under this 

approach, DOE physically dismantles a 

commercially available product, 

component-by-component, to develop a 

detailed bill of materials for the product. 

• Catalog teardowns: In lieu of 

physically deconstructing a product, 

DOE identifies each component using 

parts diagrams (available from 

manufacturer websites or appliance 

repair websites, for example) to develop 

the bill of materials for the product. 

• Price surveys: If neither a physical 

nor catalog teardown is feasible (for 

example, for tightly integrated products 

such as fluorescent lamps, which are 

infeasible to disassemble and for which 

parts diagrams are unavailable) or costprohibitive and otherwise impractical 

(e.g., large commercial boilers), DOE 

conducts price surveys using publicly 

available pricing data published on 

major online retailer websites and/or by 

soliciting prices from distributors and 

other commercial channels. 

The resulting bill of materials 

provides the basis for the manufacturer 

production cost (‘‘MPC’’) estimates. 

DOE then applies a manufacturer 

markup to convert the MPC to 

manufacturer selling price (‘‘MSP’’). The 

manufacturer markup accounts for costs 

such as overhead and profit. 

As described at the beginning of this 

section, the main outputs of the 

engineering analysis are cost-efficiency 

relationships that describe the estimated 

increases in manufacturer production 

cost associated with the higherefficiency products for the analyzed 

product classes. 

As previously discussed, DOE is 

considering several technology options 

for improving the energy efficiency of 

air circulating fans. Those technology 

options are listed in Table II.3 of this 

document. 

Issue 17: DOE requests input on the 

increase in MPC associated with 

incorporating each technology option 

for air circulating fans listed in Table 

II.3 of this document. DOE also seeks 

information on the investments 

necessary to incorporate specific design 

options, including, but not limited to, 

costs related to new or modified tooling 

(if any), materials, engineering, and 

development efforts to implement each 

design option, and manufacturing/ 

production impacts. 

DOE is also interested in determining 

a realistic production cost value for air 

circulating fans. This information is 

used to inform the MPC calculation and 

the total cost to the industry to redesign 

air circulating fans. 

Issue 18: DOE requests data showing 

the total cost of manufacturing for air 

circulating fan heads, personnel coolers, 

box fans, and table fans. 

E. Distribution Channels 

In generating end-user price inputs for 

the life-cycle cost (‘‘LCC’’) analysis and 

national impact analysis (‘‘NIA’’), DOE 

must identify distribution channels (i.e., 

how the products are distributed from 

the manufacturer to the consumer) and 

estimate relative sales volumes through 

each channel. DOE is interested in 

developing distribution channels for 

each categories of air circulating fans 

(i.e., air circulating fan heads, personnel 

coolers, box fans, and table fans) and 

may consider different channels 

depending on the input power of the 

fans or other design characteristic. 

Issue 19: DOE requests information to 

help characterize distribution channels 

for air circulating fans. DOE also 

requests data on the fraction of sales 

that go through these channels. 

F. Energy Use Analysis 

As part of the rulemaking process, 

DOE conducts an energy use analysis to 

identify how equipment is used by 

consumers, and thereby determine the 

energy savings potential of energy 

efficiency improvements. The energy 

use analysis is meant to represent the 

energy consumption of a given 

equipment when used in the field. The 

annual energy use of air circulating fans 

is calculated based on the fans’ input 

power (in watts) and annual operating 

hours per year. In any future analysis, 

DOE may consider combining air 

circulating fan input power ratings in 

each operating mode (e.g., high speed, 

medium speed, low speed) from the 

engineering analysis based on estimates 

of the distribution of annual operating 

hours at each mode. 

DOE is interested in information to 

help characterize the annual operating 

hours of air circulating fans and time 

spend in each operating mode, if 

applicable. 

In the absence of existing data 

indicating the daily hours of operation 

specific to air circulating fans, DOE may 

consider relying on the annual operating 

hours developed for ceiling fans as used 

in the final rule published on January 

19, 2017. See 82 FR 6826, 6846–6847. 

For example, for air circulating fans 

used in commercial and industrial 

applications, DOE may consider an 

estimated 12 hours of use per day 

consistent with the hours of use 

estimated for large-diameter ceiling fans 

and high-speed small diameter fans as 

used in the final rule published on 

January 19, 2017. 82 FR 6826, 6847. 

Large-diameter ceiling fans and highspeed small diameter fans are also used 

in commercial and industrial 

applications. 

Issue 20: DOE seeks information to 

help characterize the usage of air 

circulating fans. Specifically, DOE seeks 

input on data sources to help 

characterize the variability in annual 

energy consumption for air circulating 

fans. For each air circulating fan 

category, DOE is requesting data and 

information (by sectorial) related to: (1) 

Annual operating hours; and (2) fraction 

of time spent at each speed setting and 

standby mode (if applicable). 

Issue 21: For each air circulating fan 

category, DOE is also interested in 

percentage of shipments by sector of 

application. To the extent any of these 

usage parameters differ by geographical 

region or other user characteristics, DOE 

requests information to help 

characterize these variations. 

G. Life-Cycle Cost and Payback Period 

Analyses 

DOE conducts the LCC and payback 

period (‘‘PBP’’) analysis to evaluate the 

economic effects of potential energy 

conservation standards for air 

circulating fans, on individual 

consumers. For any given efficiency 

level, DOE measures the PBP and the 

change in LCC relative to an estimated 

baseline level. The LCC is the total 

consumer expense over the life of the 

equipment, consisting of purchase, 

installation, and operating costs 

(expenses for energy use, maintenance, 

and repair). Inputs to the calculation of 

total installed cost include the cost of 

the equipment—which includes MSPs, 

distribution channel markups, and sales 

taxes—and installation costs. Inputs to 

the calculation of operating expenses 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 7055 

include annual energy consumption, 

energy prices and price projections, 

repair and maintenance costs, 

equipment lifetimes, discount rates, and 

the year that compliance with new and 

amended standards is required. In this 

section, DOE discusses specific inputs 

to the LCC and PBP analysis for which 

it requests comment and feedback. 

1. Installation, Repair and Maintenance 

Costs 

As part of a potential energy 

conservation standards rulemaking, 

should one be conducted, DOE will 

review available air circulating fan 

installation, maintenance, and repair 

cost information. 

Issue 22: DOE requests information 

describing installation, maintenance, 

and repair practices of air circulating 

fans. DOE requests feedback and data on 

whether installation, maintenance, and 

repair costs of air circulating fans at 

higher efficiency levels differ in 

comparison to the baseline installation, 

maintenance, and repair costs. To the 

extent that these costs differ, DOE seeks 

supporting data and the reasons for 

those differences. 

Issue 23: DOE requests information on 

the repair rate of each air circulating fan 

category (i.e., percentage of fans 

purchased that are repaired). 

2. Lifetime 

The equipment lifetime is the age at 

which given equipment is retired from 

service. DOE typically develops survival 

probabilities using on a Weibull 

function to characterize variability in 

lifetimes. As part of a potential energy 

conservation standards rulemaking, 

DOE will review available air 

circulating fan lifetime data by category 

and sector of application. 

Issue 24: DOE seeks data and input on 

the appropriate average, minimum, and 

maximum equipment lifetimes (by 

sector of application) for air circulating 

fans in years and/or in total lifetime 

operating hours that DOE should apply 

when performing its analysis. 

3. Efficiency Distribution in the No-New 

Standards Case 

To accurately estimate the share of 

consumers that would be affected by a 

potential energy conservation standard 

at a particular efficiency level, DOE’s 

LCC analysis considers the projected 

distribution (market shares) of 

equipment efficiencies in the no-newstandards case (i.e., the case without 

amended or new energy conservation 

standards) in the compliance year. 

Issue 25: DOE seeks data and input on 

the appropriate efficiency distribution 

in the no-new standards case for each 

air circulating fan category. DOE seeks 

data that would support changes in 

efficiency distributions over time in the 

no-new standards case. To the extent 

any of the efficiency distributions in the 

no-new standards case differ by size or 

other user design characteristic within 

an air circulating fan category, DOE 

requests information to characterize 

these variations. 

H. Shipments 

DOE develops shipments forecasts to 

calculate the national impacts of 

potential energy conservation standards 

on energy consumption, net present 

value (‘‘NPV’’), and future manufacturer 

cash flows. DOE shipments projections 

are typically based on available 

historical data broken out by equipment 

class, capacity, and efficiency. Current 

sales estimates allow for a more accurate 

model that captures recent trends in the 

market. 

As part of a potential energy 

conservation standards rulemaking, 

DOE will review available historical and 

current shipments data to estimate 

current and future shipments of air 

circulating fans by category (i.e., air 

circulating fan heads, personnel coolers, 

box fans, and table fans). 

Issue 26: DOE requests 2021 annual 

sales data (or the most recent year 

available)—i.e., number of shipments— 

for air circulating fans. If disaggregated 

data of annual sales are not available for 

different air circulating fan categories, 

DOE requests more aggregated data of 

annual sales as available. 

Issue 27: DOE requests 2021 data (or 

the most recent year available) on the 

fraction of shipments in the industrial, 

commercial, and residential sectors for 

air circulating fans. In each sector, DOE 

requests 2021 data (or the most recent 

year available) on the fraction of 

shipments that represent replacement 

versus new installations. 

Issue 28: DOE requests information on 

the rate at which annual sales (i.e., 

number of shipments) of air circulating 

fans is expected to change in the next 

5–10 years. If possible, DOE requests 

this information for each air circulating 

fan category. If disaggregated data of 

annual sales are not available for each 

air circulating fan category, DOE 

requests more aggregated data of annual 

sales. 

Issue 29: DOE requests data and 

information on any trends in the fans 

market that could be used to forecast 

expected trends in market share by 

efficiency levels for air circulating fans. 

If disaggregated data are not available 

for each air circulating fan category, 

DOE requests more aggregated data.

Confidential Business Information. 

According to 10 CFR 1004.11, any 

person submitting information that he 

or she believes to be confidential and 

exempt by law from public disclosure 

should submit via email, postal mail, or 

hand delivery/courier two well-marked 

copies: one copy of the document 

marked confidential including all the 

information believed to be confidential, 

and one copy of the document marked 

‘‘non-confidential’’ with the information 

believed to be confidential deleted. DOE 

will make its own determination about 

the confidential status of the

determination. 

It is DOE’s policy that all comments 

may be included in the public docket, 

without change and as received, 

including any personal information 

provided in the comments (except 

information deemed to be exempt from 

public disclosure). 

DOE considers public participation to 

be a very important part of the process 

for developing test procedures and 

energy conservation standards. DOE 

actively encourages the participation 

and interaction of the public during the 

comment period in each stage of this 

process. Interactions with and between 

members of the public provide a 

balanced discussion of the issues and 

assist DOE in the process. Anyone who 

wishes to be added to the DOE mailing 

list to receive future notices and

Airworthiness Directives; Bombardier, 

Inc., Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Bombardier, Inc., Model CL– 

600–1A11 (600), CL–600–2A12 (601), 

and CL–600–2B16 (601–3A, 601–3R, 

and 604 Variants) airplanes. This 

proposed AD was prompted by a report 

of smoke in the aft cabin during a 

maintenance activity, which an 

investigation determined was caused by 

a faulty drain line ribbon heater. This 

proposed AD would require a general 

visual inspection of all affected potable 

water-line ribbon heater installations 

and corrective actions and other 

specified actions. The FAA is proposing 

this AD to address the unsafe condition 

on these products. 

DATES: The FAA must receive comments 

on this proposed AD by March 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
