ENERGY STAR
ENERGY STAR® Program Requirements
for Residential Ventilating Fans
Final Draft - Eligibility Criteria (Version 2.0)
Below is the FINAL DRAFT product specification (Version 2.0) for ENERGY STAR qualified residential
ventilating fans. A product must meet all of the identified criteria to earn the ENERGY STAR.
1) Definitions: Below is a brief description of a residential ventilating fan and other terms as relevant to
ENERGY STAR.
A. Residential Ventilating Fan: A ceiling, wall-mounted, or remotely mounted in-line fan designed to
be used in a bathroom or utility room, or a kitchen range hood, whose purpose is to move
objectionable air from inside the building to the outdoors. Residential ventilating fans used for
cooling (e.g., whole-house fans) or air circulation are excluded. Heat/energy recovery ventilation
fans ducted to the ventilated space and powered attic ventilators (e.g., gable fans) are excluded,
but may be considered in a future version of this specification. Residential ventilating fans with
heat lamps are excluded from this specification. This specification does not address passive
ventilation of any kind.
Note: In the previous Draft 2 specification, EPA proposed to exclude ventilating fan models that
incorporate electric resistance heating elements. It continues to be EPA's intention to exclude
electric resistance heating technologies to encourage the development of more energy-efficient
technologies. However, EPA also recognizes that for those ventilating fan models that currently
qualify as ENERGY STAR under Version 1.0, additional time will be needed to research new
energy-efficient technologies and redesign products. Therefore, ventilating fan models with
electric resistance heating elements may continue to qualify through December 31. 2004 under
this Version 2.0 specification (see Section 5). It is equally important that the manufacturer
clarify that this heat source is NOT ENERGY STAR qualified (see Section 3.C for packaging
instructions).
Due to continued manufacturer interest in labeling remote (single- and multi-port) in-line
ventilating fans and additional review of single-port product performance data, EPA has decided
to include in-line ventilating fan products in this Version 2.0 specification. Although these
products are not rated for sound, manufacturers of these products must include additional
installation instructions for these products to ensure optimum performance and quiet operation.
These requirements are presented in Sections 3.C and 4.D of this Version 2.0 specification.
Although EPA has not reviewed specific performance data for multi-port in-line fans, these
products are included due to their known similarity to single-port in-line fans, in both efficiency
and application, and the additional energy efficiency benefits derived from multi-port fan
installation in the home (i.e., one fan performing the job that would otherwise have required
multiple fans).
B.	Combination Unit: A residential ventilating fan that contains a light source for general lighting
and/or a night light.
C.	In-line Ventilating Fan: A fan designed to be located within the building structure and requires
ductwork on both intake and exhaust. Those in-line fans with only one intake are referred to as
"single port" in-line fans, while those with multiple intake ports are referred to as "multi-port" in-line
fans in this specification.
Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0	1

-------
D.	HVI 915,"HVI (Home Ventilating Institute) Procedure for Loudness Rating of Residential Fan
Products": Procedure used for testing and rating ventilation fan products for sound. This test
procedure includes laboratory requirements and methods for obtaining sound pressure, sound
power, and sone values.
E.	HVI 916,"HVI Airflow Test Standards": Airflow test standard that establishes uniform methods for
laboratory testing of powered residential ventilating equipment for airflow rate. This publication
covers the test equipment, tests of specific HVI classification groups, test reports, and policies for
maintaining the standard.
F.	HVI 920,"HVI Product Performance Certification Procedure Including Verification and Challenge
Publication that defines and specifies certain aspects of the procedures, covering such points as
the actual testing, the certification process, challenge procedures, and the use of HVI trademark
and labels.
G.	Inch of Water Gauge (w.q.): A traditional unit of pressure used to describe both water and gas
pressures. The conventional equivalent of one inch of water is 249.0889 pascals, which is
2.490889 millibars, about 0.036127 pounds per square inch (psi) or about 0.073556 inches
(1.86832 millimeters) of mercury. The word "gauge" after a pressure reading indicates that the
pressure stated is actually the difference between the absolute, or total, pressure and the ambient
air pressure at the time of the reading.
H.	Light Source: The lighting portion of a combination unit or a range hood. For units using a
compact fluorescent or fluorescent lamp, the light source includes the lamp and the ballast.
I.	Power Consumption: The operation of the fan motor consumes electrical power measured in
Watts (W). Under this specification, power used for lights, sensors, heaters, timers, or night lights
is not included in the determination of power consumption.
J. Sone: An internationally recognized unit of loudness, which simplifies reporting of sound output
by translating laboratory logarithmic decibel readings into a linear scale that corresponds to the
way people sense loudness. A sone is equal in loudness to a pure tone of 1,000 cycles per
second at 40 decibels above the listener's threshold of hearing.
K. Working Speed: The lowest speed above 100 CFM for a two speed fan and a low setting above
90 CFM for a multi-speed fan.
2) Qualifying Products: In order to qualify as ENERGY STAR, a residential ventilating fan must meet the
definition in Section 1A and the specification and testing requirements provided in Sections 3 and 4,
below. For the purposes of this specification, residential ventilating fans include the following product
types: range hoods, in-line (single and multi-port), and bathroom and utility room; including ducted and
direct-discharge models. Ventilating fans with sensors and timers may qualify under this specification.
Residential ventilating fans qualifying under this specification can also be used in small commercial
applications (e.g., bathroom of a restaurant).
3) ENERGY STAR Specification Reguirements for Qualifying Products: Only those products described in
Section 2 that meet the energy-efficiency criteria outlined in Table 1, below, may qualify for the
ENERGY STAR. In addition to these requirements, all qualifying residential ventilating fans must also
meet those requirements listed in Sections A-C, as appropriate.

*Based on measured airflow at 0.1 in. w.g. static pressure (0.2 w.g. static pressure for in-line fans).
**Tested at working speed.
Note: There was some concern within industry that limiting the size of bathroom and utility fans
would exclude larger fan models that would otherwise qualify as ENERGY STAR. EPA's initial
goal in proposing the 250 cfm limitation in the Draft 2 specification, was to avoid over ventilation.
However, it was recently brought to EPA's attention that there is demand in the housing market
for bathroom and utility fans that are larger than 250 CFM; many that could meet the proposed
Version 2.0 performance levels. Manufacturers should, however, ensure that proper sizing
methods, based on HVI and ASHRAE recommendations, are included in product literature and
packaging.
EPA has reviewed performance data on nearly 100 single-port in-line fan models representing
seven different manufacturers. According to this data, a minimum efficacy requirement of 2.8
cfm/W would represent slightly more than 25% of products in the marketplace. Please note that
this efficacy requirement is based on measured airflow at 0.20 in. w.g. static pressure; it is EPA's
understanding that these products are inherently more efficient than the comparable ceiling bath
fan. Multi-port in-line fans must meet the same requirements as single-port in-line fans to qualify
as ENERGY STAR. Stakeholders are encouraged to provide feedback on whether or not
this performance level accurately represents the top energy performers available in this
product market.
In the Draft 2 specification, EPA proposed that manufacturers be allowed to test minimum
efficacy and maximum sound ratings for Range Hoods at "Working Speed," instead of Maximum
speed, since it is widely recognized in the industry that working speed is the more common
operating condition. EPA received a comment that using working speed to measure range hood
performance would be confusing to consumers and that it is not a true indicator of product
performance. To clarify, the working speed test results are for qualification purposes only;
partners are not required to market this information to the consumer. Furthermore, based on
discussions with HVI, EPA continues to believe that working speed is the better indicator based
on the following two reasons: (1) range hoods are currently tested at HVI at low speed (typically
100 CFM), based on the ASHRAE ventilation standard for range hoods (Standard 62-1982); and
(2) consumer surveys by manufacturers over the last 10+ years indicate that range hoods are
most often used at lower speeds.
Finally, the CFM ranges provided for each product category have been revised in Table 1 for the
following reasons:
1.	Current HVI Certification requires manufacturers to list certified ventilating fans rounded
down to the nearest 10 CFM. Since EPA is requiring HVI Certification, the CFM ranges in this
specification were set to match this HVI convention.
2.	Increasing the small fan category CFM limit from 75 to 80 will allow more products to qualify,
increasing total market penetration and providing manufacturers with more opportunities to list
qualifying products in the currently underserved small fan category.

least one of the lamp types listed on the product packaging.
Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0

-------
Note: EPA's intention of excluding models that can accept incandescent lamps for general lighting
under this Version 2.0 specification is to ensure the long-term energy savings associated with using
compact fluorescent and other energy-efficient light sources. This requirement also ensures that the
consumer cannot replace the original energy-efficient lamp with an inefficient incandescent lamp,
thus guaranteeing these long-term savings. As with many ENERGY STAR products, EPA may
allow for incandescent products to initially qualify as ENERGY STAR while allowing partners time to
develop more energy-efficient technologies. As such, the Version 1.0 specification gave
manufacturers one year from the July 1, 2001 effective date to develop ENERGY STAR qualified
lighting. Implementation of this requirement has been delayed by the specification revision process;
however, ENERGY STAR partners are already qualifying ventilating fan models with fluorescent
lighting, further supporting the movement toward, and interest in, energy-efficient light sources.
However, there continues to be industry concern with the proposed exclusion of all incandescent
range hood products. EPA has received industry feedback that manufacturers of this product
category may need additional time to research and develop new energy-efficient lighting
technologies. Therefore, EPA is allowing incandescent range hood products to continue to qualify
as ENERGY STAR through December 31, 2004. As of January 1, 2005, range hoods must
comply with the lighting requirements described in Sub-Sections 3.A.1 .a. or b., above. In the short
term, EPA is addressing energy consumption of these product types by: (1) limiting the total lamp
wattage to 50 watts, similar to the fluorescent lighting requirements for bath and utility fans; and (2)
requiring a consumer recommendation on product packaging (Section 3.C, below).
B. Quality Assurance Requirements: To assure the quality of ENERGY STAR qualified residential
ventilating fans, the following quality assurance requirements must be met for a fan to earn the
ENERGY STAR:
Note: In developing ENERGY STAR specifications, EPA strives to set energy efficiency
performance levels that achieve energy savings without sacrificing performance and quality. The
Draft 1 specification identified three primary attributes that affect perceived and actual product
quality for residential ventilating fans: early product failure rate, fan sound levels, and installed fan
performance. By specifying minimum requirements in these three specific areas, EPA believes
that actual and perceived product quality will be assured for residential ventilating fans that earn the
ENERGY STAR, without undue burden to participating manufacturers.
EPA continues to receive conflicting feedback from stakeholders on this approach to assuring
quality of ENERGY STAR qualified fan models. In particular, minimum product warranty period
continues to be a divisive issue. While EPA appreciates the arguments for longer minimum product
warranties, it must also balance the goal of achieving high product quality with the equally
important goal of reaching a significant portion of the market.
ENERGY STAR product specifications are typically set to target 25% of the current market. EPA
has made some significant changes between the first Draft and this Final Draft specification in an
attempt to reach a larger market share. However, in some cases, EPA must also balance initial
market penetration with other considerations, resulting in a target lower than a 25% market share.
It is EPA's hope that overtime, ENERGY STAR market share will increase as the demand for
energy-efficient products grows. As a result of revisions proposed in this Version 2.0 specification,
EPA believes that while it may not represent 25% of the market share, it does represent a larger
market penetration of ENERGY STAR compared to the existing (Version 1.0) specification, while
continuing to ensure the performance and quality of the products.
Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0

-------
1. Early Product Failure Rate
Partner shall provide a minimum one-year warranty for a product to qualify for the ENERGY
STAR.
Note: The Tier I warranty requirement in the existing (Version 1.0) specification is two years. A
three-year warranty was scheduled to go into effect in July 2002 under Tier II; however, this
effective date was delayed due to this specification revision process.
Initial or early product failure due to faulty workmanship is the first indicator of poor product
quality. Such failures should be rare in ENERGY STAR qualified products and backed by a
minimum warranty. EPA still believes that a one-year minimum warranty is sufficient to protect
consumers from these early failures and has not yet come across any information in the
industry that proves otherwise. Furthermore, in previous drafts of this Version 2.0 draft
specification, EPA requested feedback on expanding the one-year warranty to a
comprehensive one-year warranty. EPA has not received any feedback on what this
comprehensive warranty should cover. It is not EPA's intention to delay the revision of this
specification to conduct the research needed to determine the appropriate definition of
"comprehensive." Furthermore, it is EPA's hope that by tightening up the sound and efficacy
requirements and including new installed performance requirements, this will ensure the
qualification of only high quality, long lasting products. If overtime, EPA receives information
that supports the need for a longer warranty, it may consider revisiting the current one-year
warranty at that time.
2. Fan Sound Levels:
For most ventilating fan products, fan noise is the most obvious indicator of product quality to the
consumer. Table 3, below, provides maximum noise levels allowed for residential ventilating fans
to earn the ENERGY STAR.
Table 3

Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0

-------
Note: Following the release of the Draft 2 specification, EPA continued to receive
comments on the proposed maximum sound levels. Some manufacturers felt that the
proposed levels were too stringent while others felt that these levels were not challenging
enough. After additional research and discussions with industry, EPA found that by leaving
the smaller fan category (10-80 CFM) maximum sound level at the existing Version 1.0
specification requirement of 2.0 sones, this will open up the market share to a few more
models getting EPA closer to its' 25% goal without compromising the quality associated
with the ENERGY STAR mark.
In this Final Draft Version 2.0 specification, EPA requires product testing of range hood
performance at working speed (approximately 100 CFM), instead of maximum speed. To
be consistent with bathroom and utility fan sound level requirements in Table 3, tested at
similar airflows, EPA is proposing a lower maximum sound level requirement for range
hoods, specifically from 3.0 to 2.0 sones.
EPA has taken into consideration all stakeholder suggestions received to date on these
performance levels and believes that the sound requirements proposed in this Final
Version 2.0 specification represents the top performers in the marketplace. It continues to
be EPA's hope that this specification will encourage manufacturers to produce more
models that meet both efficacy and sound requirements and open up the market
availability of ENERGY STAR qualified products.
3. Installed Fan Performance
All qualifying ventilating fan models, with the exception of in-line models, when measured by
industry standard testing procedures at 0.25 in. w.g. static pressure, shall deliver a rated airflow
(cfm) of equal or greater than the following percentages of the rated airflow delivered at 0.1 in.
w.g. static pressure for that particular model:
Product Category
Bathroom and Utility Room Fans - 10 to 80 cfm
Bathroom and Utility Room Fans - 90 to 130 cfm
Bathroom and Utility Room Fans - 140 to 500 cfm
Range Hoods - up to 500 cfm

Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0

-------
Note: It is important that an ENERGY STAR qualified ventilating fan meet consumer's
performance expectations. The inability of a fan to deliver close to its rated airflow when installed
can raise quality concerns. In the Draft 2 specification EPA proposed that ENERGY STAR
qualified ventilating fans be required to have a measured airflow at 0.25 in. w.g. static pressure
that is no less than 70% of the minimum rated airflow for the fan at 0.1 in. w.g. static pressure.
While industry members have voiced their support of including this requirement as a
measurement of product quality, EPA has also received comments indicating that 70% is too
aggressive for smaller fans and ENERGY STAR could lose a large part of the new construction
market (e.g., 50, 60, and 70 cfm models). It is also EPA's understanding that larger fans often
perform better at maintaining their airflow under increasing static pressures compared to smaller
fans. Therefore, based on a review of product performance data, EPA has lowered the airflow
performance requirement for smaller fans (10-80 cfm) to 60% of the minimum rated airflow at
0.1 in. w.g. static pressure when tested at 0.25 in. w.g. static pressure. This will ensure
ENERGY STAR qualified product availability in the bathroom/utility room fan categories providing
the builder with more energy-efficient choices based on application and room size. Since in-line
fans are already tested and evaluated under this specification at .20 in. w.g. static pressure, there
are no additional requirements for installed performance.
C. Inclusion of Installation Instruction and Consumer Recommendations: Picture diagram-type
installation instructions shall be included with each qualified ventilating fan. The instructions shall
indicate the following:
1.	How to properly seal the fan with caulk or other similar material to inhibit air leakage to the
exterior of the thermal envelope of the building.
2.	Recommended ductwork types, elbows (including radii), terminations, sealants, and lengths
that will minimize static pressure losses and promote adequate airflow.
3.	Proper installation of vibration deadening materials such as short pieces of flexible duct.
4.	Proper installation of insulation around the fan to minimize building heat loss and gain.
In-Line Fan (Additional) Installation Instructions: Manufacturers must include the following
information on the in-line product or in product literature:
To ensure quiet operation of ENERGY STAR qualified in-line and remote fans, each fan
should be installed using sound attenuation techniques appropriate for the installation.
For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct
must be installed between the exhaust or supply grille(s) and the fan. For kitchen range
hood remote ventilation applications, where metal duct is generally required by code, a
metal sound attenuator must be installed between the range hood and the fan.
Range Hoods with Incandescent Light Sources: Manufacturers must recommend the use of an
ENERGY STAR qualified CFL light bulb or incandescent bulb that uses no more than 50 watts
total. This recommendation must be provided in product literature, on product packaging, and on
Partner's Web site.
Ventilating Fan Models with Electric Resistance Heating: Qualified products with electric
resistance heating elements must include information on the product packaging, in product
literature, and on partner's Web site explaining that the heating element is designed to be used for
supplemental heating only and does not contribute to the ENERGY STAR qualification of the
product.
Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0

-------
Note: There is no minimum sound requirement for in-line fans to qualify as ENERGY STAR, since
there is no available test procedure for this fan category; however, EPA does recognize the
importance of installation of these products to ensure quiet operation. As such, specific
instruction regarding the installation of in-line fans is provided above for stakeholder
review and comment. It is EPA's intention that manufacturers include these instructions either in
product literature or directly on the qualifying model so that the contractor can review the
information prior to installation.
In this section, EPA also provides direction on the required recommendations that the
manufacturer must make to the consumer regarding range hoods with incandescent light source
sockets and fan models with electric resistance heating.
4) Product Testing: Manufacturers are required to perform tests, according to the requirements included
in this Version 2.0 specification, then submit qualifying model information to EPA for approval. Each
qualifying model must be tested and certified by HVI in accordance with HVI Standards 915, 916,
and 920. The test results must be reported using the Residential Ventilating Fan Qualified Product
Information (QPI) Form. Manufacturers are required to report fan performance information on the QPI
Form using the following units of measure:
Note: EPA received several comments from manufacturers suggesting that ENERGY STAR
qualified ventilation fans be required to have HVI certification, in accordance with HVI Standard
920. Including this requirement will ensure third-party verification and accurate reporting of
product performance. It is EPA's understanding that while testing must be done in an HVI
certified laboratory, manufacturers do not have to be HVI members to participate in the
certification program.
A.	Airflow Rating Ccfm'): The airflow of a residential ventilating fan shall be measured in cubic feet per
minute (cfm). The cfm values shall be certified by HVI and measured by the method described in
HVI Standard 916.
B.	Efficacy (cfm/W): The efficacy of the residential ventilating fan shall be expressed in cubic feet
per minute per Watt (cfm/W). Manufacturers shall calculate efficacy by using the airflow and fan
motor electrical power values certified by HVI and described in HVI Standard 916. Fan motor
electrical usage will be the only energy consumption considered for the efficacy calculation.
Energy used for other fan auxiliaries, such as lights, is not included in the determination of fan
efficacy.
C.	Sound Rating (sone): The sound output of a residential ventilating fan is measured in sones. The
sound ratings shall be certified by HVI and measured by the method described in HVI Standard
915.
D.	Static Pressure Measurements: Ventilating fan performance characteristics such as motor
wattage, cfm, and sones must be reported to EPA at specific static pressures. These
measurements vary depending upon the fan type and follow HVI 920 rating points.
Measurements shall be certified by HVI and conducted in accordance with HVI Standard 920.
The static pressure measurements are listed below.
1. Ducted products (products with one duct such as bathroom fans, utility fans, and kitchen
range hoods): 0.1 in. w.g. static pressure
a. Partner must also test and report products at 0.25 in. w.g. static pressure for airflow (cfm)
Final Draft ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0	10

-------
b. Partner is not required to test sound levels or wattage at 0.25 in. w.g. static pressure
2.	Direct discharge (non-ducted) products: 0.03 in. w.g. static pressure
3.	In-line ventilating fans: 0.20 in. w.g. static pressure (Wattage and cfm only)
Note: Per standard industry practice and HVI certification requirements, in-line fans must be tested
at 0.20 in. w.g. static pressure under this Version 2.0 specification. In-line fans are not required to
be tested for sound under this specification; however, EPA understands the importance proper
installation of these products and as a result, installation instructions are proposed in Section 3C of
this specification.
5) Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR under
the Version 2.0 specification will be defined as the effective date of this agreement. The ENERGY
STAR Residential Ventilating Fans (Version 2.0) specification shall go into effect on October 1, 2003.
Any previously executed agreement on the subject of ENERGY STAR qualified vent fans, shall be
terminated effective October 1, 2003.
Note: In the Draft 2 specification, EPA proposed an effective date of October 1, 2003. Based on
manufacturer feedback received by EPA, manufacturers feel that this is an appropriate effective date
for this Version 2.0 specification.
A.	Qualifying and Labeling Products under the Version 2.0 Specification: All products, including
models originally qualified under Version 1.0 with a date of manufacture on or after October 1,
2003, must meet the new Version 2.0 requirements in order to use the ENERGY STAR on the
product or in product literature. The date of manufacture is specific to each unit, and is the date
(e.g., month and year) of which a unit is considered to be completely assembled.
B.	Elimination of Automatic Grandfathering: EPA does not allow grandfathering under this Version
2.0 specification. ENERGY STAR qualification under Version 1.0 is not automatically
granted for the life of the product model. Therefore, any product sold, marketed, or identified
by the manufacturing partner as ENERGY STAR must meet the current specification in effect at
that time.
C.	Phase-Out of Ventilating Fan Models with Resistance Heating: Starting January 1, 2005,
ventilating fans with electric resistance heaters will no longer qualify as ENERGY STAR.
D.	Phase-Out of Range Hood Models with Incandescent Lighting: Starting January 1, 2005, range
hoods with incandescent light sources or sockets that accept incandescent lamps, will no longer
qualify as ENERGY STAR. Any range hood qualifying with lighting must meet the requirements of
Table 2 in this Version 2.0 specification.
Note: As of October 1, 2003, models that qualified under the Version 1.0 specification must
meet the requirements of the new Version 2.0 specification to remain qualified as ENERGY
STAR. Products that do not meet new Version 2.0 requirements will be removed from the
ENERGY STAR Web site. These models may continue to bear the ENERGY STAR mark as it
is sold through the retail distribution channel; however, only those models that meet the new
Version 2.0 specification will be able to be manufactured and sold by the manufacturer as
ENERGY STAR.
Effective dates for the phase-out of range hood models with incandescent lighting and
bath/utility fan models with electric resistance heating are included in this section for reference.

6) Future Specification Revisions: ENERGY STAR reserves the right to revise the specification should
technological and/or market changes affect its usefulness to consumers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through industry discussions.
