Program Requirements for Residential
Windows, Doors, and Skylights – Version 5.0
Partner Commitments
Eligible Organizations:
Manufacturers (and private labelers) of Residential Windows, Doors, and
Manufacturers of Residential Window, Door, and Skylight Components
The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing and marketing of ENERGY STAR qualified windows, doors, and skylights. The ENERGY STAR
PARTNER must adhere to the following program requirements:
• Comply with the current ENERGY STAR Eligibility Criteria defining the requirements that must be met for
use of the ENERGY STAR on windows, doors, and skylights and specifying the National Fenestration
Rating Council (NFRC) certification requirement for windows, doors, and skylights. The U.S. Department
of Energy (DOE) 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
DOE’s request;
• Comply with current ENERGY STAR Identity Guidelines, ENERGY STAR Marks, Maps, and Messaging:
Simplified Marketing Guidelines for Partners, and other guidelines specific to the program area. These
guidelines describe how the ENERGY STAR name, marks, and labels 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;
• Offer at least one ENERGY STAR qualified model of a window, door, or skylight or manufacture
components that are used in the construction of qualified windows, doors, or skylights before activating
this agreement. Windows, doors, or skylights must appear under the PARTNER’s name in the National
Fenestration Rating Council’s (NFRC) Certified Product Directory (CPD);
• Provide clear and consistent labeling of ENERGY STAR qualified windows, doors, and skylights and
display units for these products. When PARTNER labels the product, it must meet the specification in
effect at that time. The ENERGY STAR for Windows, Doors, and Skylights Product Qualification Label
must be clearly displayed on ALL qualified windows, doors, and skylights. ALL display units for qualified
products must display the ENERGY STAR for Windows, Doors, and Skylights Display Unit Label. Labeling
qualified products and display units is not optional. Components may not carry an ENERGY STAR label or
logo. The appropriate ENERGY STAR mark must be clearly displayed on the manufacturer’s Internet site
and in product literature (e.g., catalogues, user manuals, spec sheets, etc.) where information about
ENERGY STAR qualified models is displayed;
• Provide a Qualified Product Information form (QPI). Once PARTNER submits its QPI form, PARTNER’s
company name will be featured in the product search for ENERGY STAR qualified windows, doors, and
skylights on the ENERGY STAR Web site. PARTNER is responsible for submitting a new QPI form at
least once per year. TDD manufacturer partners must also submit a copy of the NFRC Certification
Authorization Report documenting the computer simulated U-factor ratings for their qualified products.
Component manufacturers do not need to provide QPI forms;
• Notify DOE of a change in the designated responsible party or contacts for windows, doors, and skylights
within 30 days and update all contact and organization information at least once per year.

Performance for Special Distinction
In order to receive additional recognition and/or support from DOE for its efforts within the Partnership, the
ENERGY STAR PARTNER may consider the following voluntary measures and should keep DOE informed on the
progress of these efforts:
• May provide to DOE or its contractor for ENERGY STAR for Windows, Doors, and Skylights, on an annual
basis, unit shipment data to assist in determining the market penetration of ENERGY STAR qualified
windows, doors, and skylights. Specifically, PARTNER may submit the total number of ENERGY STAR
qualified units shipped and the total number of units shipped to U.S. destinations broken down by product
category (window, door, skylight) and state or regions specified by DOE.
The data for each calendar year may be submitted to DOE or its contractor, in electronic format, no later
than March 31 of the following year and may be provided directly by PARTNER or through a third party.
Data submitted to the DOE contractor for ENERGY STAR for Windows, Doors, and Skylights will be
aggregated before it is transferred to DOE. The data will be used by DOE only for program evaluation
purposes and will be closely controlled. If requested under the Freedom of Information Act (FOIA), DOE
will argue that the data is exempt. Any information used will be masked by DOE so as to protect the
confidentiality of PARTNER.
• Consider energy efficiency improvements in company facilities and pursue to benchmark their buildings
through the ENERGY STAR Buildings program;
• Purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials’ contact information to DOE 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 mark(s) on PARTNER web site and in other promotional materials. If
information concerning ENERGY STAR is provided on PARTNER web site, DOE may provide links where
appropriate to PARTNER web site;
• Provide a simple plan to DOE outlining specific measures PARTNER plans to undertake beyond the
program requirements listed above. By doing so, DOE may be able to coordinate, communicate, and/or
promote PARTNER’s activities, provide a DOE 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 for which PARTNER would like DOE to be
aware. 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 DOE on
one print advertorial and one live press event;
• Provide quarterly, written updates to DOE as to the efforts undertaken by PARTNER to increase
availability of ENERGY STAR qualified products and to promote awareness of ENERGY STAR and its

available from NFRC). Includes ¼- and ½-lite doors.
iii) > ½-lite: A door with > 29.8 percent glazing (based on NFRC 100-2004 or the most recent procedure
available from NFRC). Includes ¾-lite and fully glazed doors.
c) Skylight: A window designed for sloped or horizontal application in the roof of a residential building, the
primary purpose of which is to provide daylighting and/or ventilation. May be fixed or operable. Skylights
have their own set of ENERGY STAR criteria. Tubular Daylighting Devices are included under the skylight
d) Sliding Entry Door: A door that contains one or more manually operated panels that slide horizontally
within a common frame. Sliding doors are included under the door criteria and definition.
e) Swinging Entry Door: A door system having, at a minimum, a hinge attachment of any type between a leaf
and jamb, mullion, or edge of another leaf or having a single, fixed vertical axis about which the leaf
rotates between open and closed positions. Swinging entry doors are included under the door criteria and
f) Tubular Daylighting Device (TDD) or tubular skylight: A non-operable device primarily designed to transmit
daylight from a roof surface of a residential building to an interior ceiling surface via a tubular conduit. The
device consists of an exterior glazed weathering surface, a light transmitting tube with a reflective inside
surface and an interior sealing device, such as a translucent ceiling panel. TDDs are included under the
skylight criteria.
g) Dynamic Glazing Product: Any fenestration product that has the fully reversible ability to change its
performance properties, including U-factor, SHGC, or Visual Transmittance. This includes, but is not
limited to, shading systems between the glazing layers and chromogenic glazing.
i) Switch-able Glazing Product: An electrochromic glass system that can be tinted or untinted in
response to an electronic control signal or environmental change.
ii) Internal Shading System: A fenestration product that includes blinds or shades positioned between
glass panes that can open or close.
h) Window, door, and skylight components: Components used by an ENERGY STAR partner in the
