Commitment
The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing of ENERGY STAR qualified residential ventilating fans. The ENERGY STAR Partner must
adhere to the following program requirements:
¦	comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must
be met for use of the ENERGY STAR certification mark on residential ventilating fans and
specifying the testing criteria for residential ventilating fans. EPA may, at its discretion, conduct
tests on products that are referred to as ENERGY STAR qualified. These products may be
obtained on the open market, or voluntarily supplied by Partner at EPA's request;
¦	comply with current ENERGY STAR Identity Guidelines, describing how the ENERGY STAR
logos and name may be used. Partner is responsible for adhering to these guidelines and for
ensuring that its authorized representatives, such as advertising agencies, dealers, and
distributors, are also in compliance;
¦	qualify at least one ENERGY STAR qualified residential ventilating fan model within one year of
activating the residential ventilating fans portion of the agreement. When Partner qualifies the
product, it must meet the specification (e.g., Tier 1 or 2, if applicable) in effect at that time;
¦	provide clear and consistent labeling of ENERGY STAR qualified residential ventilating fans. The
ENERGY STAR label must be clearly displayed on the front/inside of the product, in product
literature (i.e., user manuals, spec sheets, etc.), and on the manufacturer's Internet site where
information about ENERGY STAR qualified models is displayed;
¦	provide to EPA, on an annual basis, an updated list of ENERGY STAR qualifying ventilating fan
models. Once the Partner submits its first list of ENERGY STAR qualified ventilating fan models,
the Partner will be listed as an ENERGY STAR Partner. Partner must provide annual updates in
order to remain on the list of participating product manufacturers;
¦	provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in
determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total
number of ENERGY STAR qualified residential ventilating fans shipped (in units by model) or an
equivalent measurement as agreed to in advance by EPA and Partner. Partner is also
encouraged to provide ENERGY STAR qualified unit shipment data segmented by meaningful
product characteristics (e.g., capacity, size, speed, or other as relevant), total unit shipments for
each model in its product line, and percent of total unit shipments that qualify as ENERGY STAR.
The data for each calendar year should be submitted to EPA, preferably in electronic format, no
later than the following March and may be provided directly from the Partner or through a third
party. The data will be used by EPA only for program evaluation purposes and will be closely
controlled. If requested under the Freedom of Information Act (FOIA), EPA will argue that the data
is exempt. Any information used will be masked by EPA so as to protect the confidentiality of the
Partner;
¦	notify EPA of a change in the designated responsible party or contacts for residential ventilating
fans within 30 days.

Performance for Special Distinction
In order to receive additional recognition and/or support from EPA for its efforts within the
Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should keep
EPA informed on the progress of these efforts:
¦	consider energy efficiency improvements in company facilities and pursue the ENERGY STAR
label for buildings;
¦	purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials' contact information to
EPA for periodic updates and coordination. Circulate general ENERGY STAR qualified product
information to employees for use when purchasing products for their homes;
¦	ensure the power management feature is enabled on all ENERGY STAR qualified monitors in use
in company facilities, particularly upon installation and after service is performed;
¦	provide general information about the ENERGY STAR program to employees whose jobs are
relevant to the development, marketing, sales, and service of current ENERGY STAR qualified
product models;
¦	feature the ENERGY STAR logo(s) on Partner Web site and in other promotional materials. If
information concerning ENERGY STAR is provided on the Partner Web site as specified by the
ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources
section on the ENERGY STAR Web site at www.enenavstar.gov). EPA may provide links where
appropriate to the Partner Web site;
¦	provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the
program requirements listed above. By doing so, EPA may be able to coordinate, communicate,
and/or promote Partner's activities, provide an EPA representative, or include news about the
event in the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may
be as simple as providing a list of planned activities or planned milestones that Partner would like
EPA to be aware of. For example, activities may include: (1) increase the availability of ENERGY
STAR qualified products by converting the entire product line within two years to meet ENERGY
STAR guidelines; (2) demonstrate the economic and environmental benefits of energy efficiency
through special in-store displays twice a year; (3) provide information to users (via the Web site
and user's manual) about energy-saving features and operating characteristics of ENERGY STAR
qualified products; and (4) build awareness of the ENERGY STAR Partnership and brand identity
by collaborating with EPA on one print advertorial and one live press event;
¦	provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR
and its message.

ENERGY STAR® Program Requirements
for Residential Ventilating Fans
Eligibility Criteria
Below is the 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.
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.
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.g.): 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 as defined in "HVI Supplement - Range Hood Working Speed."

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.
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:
A.	Airflow Rating (cfm): 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 Reference Measurements: Ventilating fan performance characteristics such as
ENERGY STAR Program Requirements for Residential Ventilating Fans - Version 2.0	8

-------
motor wattage, cfm, and sones must be reported to EPA at specific static pressures. These
reference measurements vary depending upon the fan type and follow HVI 920 rating points.
Reference measurements shall be certified by HVI and conducted in accordance with HVI
Standard 920. The static pressure reference measurements are listed below for each qualifying
fan type.
1.	Ducted products (products with one duct such as bathroom and utility room fans): 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)
b.	Partner is not required to test sound levels or wattage at 0.25 in. w.g. static pressure
2.	Ducted range hoods must be tested at working speed as defined in "HVI Supplement - Range
Hood Working Speed."
3.	Direct discharge (non-ducted) products: 0.03 in. w.g. static pressure
4.	In-line ventilating fans: 0.20 in. w.g. static pressure (Wattage and cfm only)
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.
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.
