`CHAPTER 3. MARKET AND TECHNOLOGY ASSESSMENT
`
`3.1
`
`INTRODUCTION
`
`This chapter details the market and technology assessment that the U.S. Department of
`Energy (DOE) has carried out in support of the preliminary analysis for energy conservation
`standards for residential furnace fans. It consists of two sections: the market assessment and the
`technology assessment. The goal of the market assessment is to develop a qualitative and
`quantitative characterization of the residential furnace fan industry and market structures, based
`on publicly available information and data and information submitted by manufacturers and
`other interested parties. The key result of the technology assessment is a preliminary list of
`technologies that can improve the efficiency of residential furnace fans.
`
`Because furnace fans are a component used in central residential heating, ventilation and
`air-conditioning (HVAC) products, DOE gathered relevant market information for residential
`furnaces, modular blowers, and hydronic air handlers. The majority of furnace fans covered in
`this rulemaking are components of residential furnaces. In addition, data are more extensive and
`readily available for residential furnaces compared to the other HVAC products that use furnace
`fans covered in this rulemaking. As a result, DOE relied heavily on residential furnace
`information to assess the furnace fan market. Little market data is available for electric
`furnaces/modular blowers. AHRI does not include information regarding electric
`furnaces/modular blowers in either its furnaces or central air conditioner (CAC) products
`databases. DOE expects that shipments of hydronic air handlers are significantly fewer than for
`furnaces. In addition, there are no DOE energy conservation standards for hydronic air handlers.
`Consequently, little market data is available for these products as well.
`
`3.1.1 Product Definitions and Scope of Coverage
`
`EPCA gives DOE authority to consider and prescribe new energy conservation standards
`or energy use standards for electricity used for purposes of circulating air through duct work. (42
`U.S.C. 6295(f)(4)(D)) Consequently, DOE tentatively defines “furnace fan” to mean any
`electrically-powered device used in residential central HVAC systems for the purposes of
`circulating air through ductwork. DOE considers a typical furnace fan as consisting of a fan
`motor and its controls, an impeller, and a housing, all of which are components of an HVAC
`product that includes additional components, such as the cabinet.

`

`DOE recognizes that a significant number of products may fit its broad interpretation of
`the statutory language. Figure 3.1.1 shows the various combinations of HVAC products that are
`used to construct typical residential HVAC systems. The boxes outlined in red represent HVAC
`products that include a furnace fan according to DOE’s interpretation of the statutory language.

`
`DOE’s preliminary approach is to address products for which DOE has sufficient data
`and information in this rulemaking, and DOE may consider other such products in a future
`rulemaking, as data become available. . For this rulemaking, DOE considered furnace fans used
`in products: (1) for which circulation fan energy consumption is not already covered in
`associated rulemakings; (2) for which sufficient data were available for its analyses; and (3) that
`could be tested using a similar test method (i.e., setup and equipment, instruments and methods
`of measure, and range of operating conditions). . The following list describes the furnace fans
`which DOE plans to address in this rulemaking.
`
`• Products addressed in this rulemaking: the furnace fans used in weatherized and
`non-weatherized gas furnaces, oil furnaces, electric furnaces, modular blowers,
`and hydronic air handlers
`• Products not addressed in this rulemaking: other products that incorporate
`furnace fans, such as CAC blower-coil units, through-the-wall air handlers,
`SDHV air handlers, ERV, HRV, draft inducer fans, or exhaust fans
`
`The products for which DOE is not considering standards in this rulemaking did not
`compare favorably to the included products based on the aforementioned criteria. DOE is not
`considering in this rulemaking fans used in any non-ducted products, such as whole-house
`ventilation systems without ductwork, CAC condensing unit fans, room fans, and furnace draft
`inducer fans because these products do not circulate air through ductwork. DOE did not
`prioritize furnace fans used in CAC blower-coil units, SDHV air handlers, and through-the-wall
`air handlers because the electrical energy consumption of these furnace fans is included in the
`
`3-2
`
`4
`
`

`

`
`
`SEER and HSPF metrics that DOE uses to regulate residential CAC and heat pump products.
`Chapter 2 of this TSD includes a detailed discussion of how the SEER metric accounts for
`furnace fan electrical energy consumption as it relates to the scope of coverage of this
`rulemaking.
`
`The HVAC products considered in this rulemaking can be broadly classified as either a
`furnace or central air conditioner (note that DOE’s definition of furnace extends to hydronic air
`handlers). 77 FR 28677 Therefore, using the identified scope of coverage, the energy
`conservation standard will be broadly applicable to HVAC products with heating input capacities
`less than 225,000 Btu per hour and cooling capacities less than 65,000 Btu/h. These
`specifications are consistent with the DOE definitions for residential “furnace” and “central air
`conditioner” (10 CFR 430.2).
`
`Figure 3.1.2 depicts the market share by shipments of HVAC products that include
`furnace fans. The slices outlined in black represent products that are not addressed in this
`rulemaking. The provisional scope of coverage of this preliminary analysis includes 63% of
`HVAC products that include furnace fans.
`
`Figure 3.1.2: Market Share of Products Containing Furnace Fans (AHRI) 1
`
`
`
`
`
`According to Residential Energy Consumption Survey 2009 (RECS 2009) data, 61.6%
`(70 million) of U.S. homes have central warm-air furnaces.2 Similar statistics are not available
`
`
`
`3-3
`

`
`

`

`
`
`for modular blowers or hydronic air handlers.a Electrical consumption attributable to residential
`furnace fans accounts for 0.40 quads/year in source energy, which is approximately 2 percent of
`total residential energy use.3
`
`
`3.1.2 Product Classes
`
`DOE categorized furnace fans into product classes and intends to formulate a separate
`energy conservation standard for each in this rulemaking. EPCA specifies the criteria for product
`class separation, which include: (1) the type of energy consumed; (2) capacity; or (3) other
`performance-related features, such as those that provide utility to the consumer or other features
`deemed appropriate by the Secretary that would justify the establishment of a separate energy
`conservation standard. (42 U.S.C. 6295(q)) DOE identified nine key product classes and 12
`additional product classes differentiated by application and internal structure. Key product
`classes are those representing most of the energy use associated with furnace fans. DOE directly
`analyzed the nine key product classes. The 12 additional product classes represent significantly
`fewer shipments and significantly less energy use. For the preliminary analysis, DOE grouped
`each non-key product class with a key product class to which it is closely related in application
`and internal structure (i.e. the primary criteria used to differentiate between product classes).
`DOE assigned the engineering results of each key product class to the non-key product classes
`with which it is grouped. Table 3.1.1 presents the 21 product classes and maps the additional
`product classes to the nine key product classes.
`
`
`
`a RECS 2009 provides data on the heating source but not the distribution system. For hydronic air handlers, the heat
`is provided either by a boiler or a water heater and distributed with the air handler. Modular blowers generally are
`paired with a separate heating product such as an electric duct heater, or they may be installed in systems that do not
`provide heat.

`
`Each product class title includes descriptors that indicate the application and internal
`structure of its included products. Weatherized and non-weatherized are descriptors that indicate
`whether the HVAC product is installed outdoors or indoors, respectively. Weatherized products
`also include an internal evaporator coil, while non-weatherized products are not shipped with an
`evaporator coil but may be designed to be paired with one.
`

`
`

`

`
`
`Condensing refers to the presence of a secondary, condensing heat exchanger in addition
`to the primary combustion heat exchanger in certain furnaces. The presence of a secondary heat
`exchanger increases internal static pressure. As a result, DOE expects that furnace fans used in
`condensing units will consume more electrical energy than similar, non-condensing units.
`
`Manufactured home products meet certain design requirements that allow them to be
`installed in manufactured homes. They require direct venting and are usually subject to more
`stringent space constraints. As a result, DOE expects that furnace fans used in manufactured
`home products will consume a different amount of electric energy than furnace fans installed in
`similar HVAC products that are designed for site-built applications.
`
`Descriptors like gas, oil, electric or hydronic indicate the type of fuel or working fluid
`that the HVAC product uses to produce heat, which determines the type and geometry of the
`primary heat exchanger used in the HVAC product. Hydronic products include parenthetical
`descriptors to indicate whether the product is designed to be used for both heating and cooling,
`or heat only, as well as whether the product includes an internal evaporator coil.
`
`3.1.3 Test Procedures
`
`Pursuant to EPCA, DOE must establish test procedures in order to allow for the
`development of energy conservation standards that will address the electrical consumption of
`furnace fan products. (42 U.S.C. 6295(o)(3)(A)) In the framework document, DOE sought
`comment on a number of furnace fan test procedure related issues primarily regarding selection
`of an appropriate reference standard and rating metric. DOE considered the feedback it received
`on the test procedure related issues in the development of the test procedure. A detailed
`discussion of these comments and DOE’s responses is included in the furnace fan test procedure
`notice of proposed rulemaking (NOPR) that DOE published on May 15, 2012. 77 FR 28674 A
`summary of the proposed test procedure is provided in the paragraphs that follow. DOE based its
`preliminary analyses for furnace fans on this proposed test procedure.
`
`In the test procedure NOPR, DOE proposed to incorporate by reference provisions from
`American National Standards Institute (ANSI)/Air Movement and Control Association
`International, Inc. (AMCA) 210-07 | ANSI/American Society of Heating, Refrigerating and Air
`Conditioning Engineers (ASHRAE) 51-07, Laboratory Methods of Testing Fans for Certified
`, hereinafter referred to as “ANSI/AMCA 210-07.” The specific
`Aerodynamic Performance Rating
`provisions DOE proposed to include from ANSI/AMCA 210-07 are definitions, test setup and
`equipment, test conditions, and procedures for measuring airflow and external static pressure. In
`addition to these provisions, DOE proposed provisions for measuring electrical energy
`consumption using an electrical power meter. DOE also proposed to specify methods for
`measuring standby mode and off mode energy consumption for hydronic air handlers that are
`identical to those of the DOE residential furnaces test procedure for these modes. (10 CFR part
`430, subpart B, appendix N, section 8.0) In addition, DOE proposed calculations to derive the
`rating metric based on the measured values.
`
`
`DOE proposed to establish a new metric, the fan efficiency rating (FER), as the furnace
`fan efficiency rating metric. FER is the estimated annual electrical consumption normalized by
`total annual operating hours and the airflow measured in the maximum airflow-control setting at
`
`3-6
`
`8
`
`

`

`
`
`a specified external static pressure (ESP). The estimate of annual electrical consumption is a
`weighted average of Watts measured separately for multiple airflow-control settings at different
`ESPs. These ESPs are determined by a reference system curve, which is developed using a
`specified airflow-control setting and ESP. This reference system curve is intended to represent
`typical ductwork systems used for circulation of air. DOE also proposed an integrated fan
`efficiency rating (IFER) for hydronic air handler units that integrates standby and off mode
`electrical consumption with active mode electrical consumption. DOE determined the reference
`system criteria specified in the test procedure NOPR through analysis of ductwork field data. 77
`FR 28683 Figure 3.1.3 provides an example of the measured data that is collected to calculate
`FER and how the reference system curve is used to identify the operating points.
`
`
`Figure 3.1.3: Example of Test Data Required to Derive FER for a 70KBtu/h, 3-ton, NWG-
`NC Furnace Fan with PSC Fan Motor
`
`
`Table 3.1.2 presents the inputs that DOE proposes to use to calculate FER. These inputs
`include the power measured at the operating points identified in the example above and the
`proposed estimates for annual operating hours for each function, each of which is associated with
`an airflow-control setting (i.e. a furnace fan performs the cooling function in the maximum
`airflow-control setting. The example power measurements are multiplied by the estimated annual
`operating hours to calculate the estimated annual electrical energy consumption for each
`respective function. The sum of estimated annual consumption for each function represents the
`total estimated electrical energy consumption of the furnace fan.

`
`3.2 MARKET ASSESSMENT
`
`The following market assessment identifies manufacturer trade associations, domestic
`and international manufacturers of residential furnace fans and their corresponding market
`shares, and regulatory and non-regulatory programs to incentivize or mandate improved
`efficiency. The market assessment also describes the cost structure for the residential furnace fan
`industry and summarizes relevant market performance data.
`
`3.2.1 Trade Associations
`
`DOE identified the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), Air
`Movement and Control Association, Inc. (AMCA), Heating, Air-conditioning & Refrigeration
`Distributors International (HARDI), and Air Conditioning Contractors of America (ACCA) as
`the key trade groups that support, or have an interest in, the residential furnace fan industry.
`
`AHRI is a national trade association of manufacturers of residential, commercial, and
`industrial appliances and equipment, components, and related products. AHRI was established in
`January of 2008 when the Air-Conditioning and Refrigeration Institute (ARI) merged with the
`Gas Appliance Manufacturers Association (GAMA). AHRI’s member companies are responsible
`for over 90 percent of the residential and commercial air conditioning and space heating
`equipment sold in North America.4 AHRI develops and publishes technical standards for
`residential and commercial equipment using rating criteria and procedures for measuring and
`certifying equipment performance. AHRI also participates in developing U.S. and international
`standards. AHRI administers the GAMA Certification program that tests and certifies the
`performance of gas- and oil-fired central furnaces that use single-phase electric current or DC
`and that have a heat input rate of less than 225,000 Btu/h. AHRI maintains the AHRI Directory
`of Certified Product Performance that lists all products that have been certified by the AHRI.
`AHRI also administers the ARI Performance Certified program that tests and certifies the
`performance of central air conditioners and heat pumps, as well as many other products
`manufactured by AHRI members. AHRI maintains the AHRI Directory of Certified Product
`Performance that lists all products that have been certified by the AHRI.b
` AHRI maintains
`certified performance directories for both air conditioners and heat pumps rated below 65,000
`Btu/h. The AHRI directories subdivide these products based upon certain defining
`characteristics, such as single package or split system and coil only or coil and blower
`combinations.
`
`AMCA is a not-for-profit international association of the world's manufacturers of related
`air system equipment - primarily, but not limited to: fans, louvers, dampers, air curtains, airflow
`measurement stations, acoustic attenuators, and other air system components for the industrial,
`commercial and residential markets. AMCA publications and standards are developed when
`sufficient interest has been expressed by AMCA members. The proposed DOE test procedure
`5
`uses AMCA 210-2007 as a reference standard.

`

`
`
`HARDI is an international trade organization that represents over 450 wholesale
`companies in the HVAC industry, including 17 international companies, plus over 300
`manufacturing associates and nearly 140 manufacturer representatives. HARDI estimates that its
`members represent 80 percent of the dollar value of the HVACR products sold through
`distribution. In 2003, the organization was formed from the consolidation of the North American
`Heating, Refrigeration & Air Conditioning Wholesalers (NHRAW) and Air-conditioning &
`Refrigeration Wholesalers International (ARWI).6

`ACCA is a nationwide trade organization that represents over 4,000 air conditioning
`contractors. ACCA supports the HVACR industry by bringing contractors together and
`providing technical, legal, and marketing resources. ACCA is “the only nationwide organization
`of, by and for the small businesses that design, install and maintain indoor environmental
`7
`systems.”
`
`
`3.2.2 Manufacturers and Market Share
`
`DOE considers the manufacturer of the HVAC product in which the furnace fan is used
`to be the furnace fan manufacturer. DOE is aware that HVAC product manufacturers purchase
`many of the components in the furnace fan assembly, such as the motor and impeller, from
`separate component manufacturers. However, the HVAC product manufacturer determines the
`design requirements, selects the purchased components based on these requirements, and
`performs the final assembly and integration of the fan assembly into the HVAC product. For
`these reasons, DOE considers the HVAC product manufacturer to be the furnace fan
`manufacturer. DOE examined its database of residential furnaces, the AHRI directories for
`residential CAC and heat pumps, HVAC product manufacturers’ websites, and product catalogs
`to identify HVAC product manufacturers. All manufacturers listed in DOE’s database for
`residential furnaces and CAC and heat pumps are shown in Table 3.2.1. DOE is aware that some
`manufacturers included in this table also manufacture hydronic air handlers. However, DOE was
`unable to find a central source of information to identify and create an exhaustive list of hydronic
`air handler manufacturers. HVAC product manufacturers may offer multiple brand names. DOE
`identified more than 50 brands under which HVAC products are manufactured and marketed.
