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 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 for Windows. Doors and
Skylights Label and Promotional Map Use Guidelines. ENERGY STAR Display Unit Labeling Guidelines
for Manufacturers and Retailers 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 window, door, or skylight model or manufacture components
that are used in the construction of qualified windows, doors, or skylights before activating this agreement.
When PARTNER labels the product, it must meet the specification in effect at that time;

Provide clear and consistent labeling of ENERGY STAR qualified windows, doors, and skylights and
display units for these products. The ENERGY STAR for Windows, Doors, and Skylights Product
Qualification Label must be clearly displayed on qualified windows, doors, and skylights. Display units
must display the ENERGY STAR for Windows, Doors, and Skylights Display Unit Label. The appropriate
ENERGY STAR mark must be clearly displayed on the manufacturer's Internet site and in product
literature (i.e., catalogues, user manuals, spec sheets, etc.) where information about ENERGY STAR
qualified models is displayed;

Provide a Qualified Product Information form (QPI), preferably in electronic format. Once PARTNER
submits its QPI form and DOE signs PARTNER'S Partnership Agreement, PARTNER'S company name
will be listed as an ENERGY STAR PARTNER. Component manufacturers must provide a Qualifying
Component Information form (QCI) in place of a QPI form. PARTNER is responsible for submitting a new
QPI or QCI form as needed to update its account profile with ENERGY STAR;

Notify DOE of a change in the designated responsible party or contacts for windows, doors, and skylights
within 30 days.

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, entry door, skylight, patio door) 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

ENERGY STAR® Eligibility Criteria for
Residential Windows, Doors, and Skylights

Below are the product criteria for ENERGY STAR qualified windows, doors, and skylights. A product must meet all
of the identified criteria to be labeled as ENERGY STAR qualified by its manufacturer.

1) Definitions:

a) Window: An entire glazed unit designed for a vertical installation in an external wall of a residential building
to allow for views and natural daylighting. May be fixed or operable.

b) Door: A residential entry or patio door system including door leaf, frame, and lites, where applicable.

c) Skylight: An entire glazed unit designed for a sloped or horizontal application in the roof of a residential
building to allow for natural daylighting. May be fixed or operable.

d) Entry door: An exterior door other than glass doors.

e) Patio door: A hinged or sliding glass door.

f) Tubular daylighting device (tubular skylight): A device consisting of a glazed entrance aperture, a reflective
cylindrical light pipe, and a glazed exit aperture installed in the roof of a residential building to allow for
natural daylighting.

g) Window, door and skylight components: Components used in the construction of a qualified window, door,
or skylight including, but not limited to, coated glass, frame profiles, and warm edge spacers.

h) Private labeler: A company that markets under its own name windows, doors, or skylights manufactured
by a different company that is an ENERGY STAR for Windows, Doors, and Skylights PARTNER.

i) U-Factor: The rate of non-solar heat loss or gain through a material or assembly. Expressed here in units
of Btu/hft2oF.

j) Solar Heat Gain Coefficient (SHGQ: The fraction of solar radiation admitted through a window, door, or

skylight. Expressed as a value between 0 and 1.
k) NFRC 1997 Procedures: Product testing and simulation procedures officially released by NFRC in 1997,
which provided residential and commercial ratings for each product based on two distinct product test
sizes.

I) NFRC 2001 Procedures: New product testing and simulation procedures officially released by NFRC in
2001, which provide more accurate ratings of products and specify a single standard test size for each
product type.

m) RES97 rated at 90 degrees: NFRC 100 1997 procedures rated skylights at a 90 degree angle, generating
a lower reported U-Factor than the same skylight rated under the NFRC 2001 procedures. RES97 rated
skylights may be present in the marketplace until March 31, 2008. NFRC labels for products using this
procedure state: "RES97 rated at 90 degrees."
n) ENERGY STAR Climate Zone: See ENERGY STAR Climate Zone Map on page 5. A complete list of
ENERGY STAR Climate Zones by state, county and city is available from the Partner Resources section
of ENERGY STAR for Windows, Doors, and Skylights web pages accessible via
http://www.energystar.gov/windows or from DOE or its contractor.

2) Eligible Products: Windows, doors (including entry and patio), and skylights (including tubular daylighting
devices) that meet the definitions specified above and testing, certification, and ENERGY STAR qualification
criteria specified below.

3) Testing and Certification Criteria: The performance of windows, doors, and skylights must be independently
tested and certified in accordance with National Fenestration Rating Council (NFRC) procedures for U-Factor
(NFRC 100) and Solar Heat Gain Coefficient (NFRC 200). Products may be rated under either the NFRC 1997
or NFRC 2001 procedures.

4) Effective Date: The date that a manufacturer may begin to qualify products as ENERGY STAR will be defined

ENERGY STAR Program Requirements for Windows, Doors, and Skylights (6/6/2005) 3

-------
as the effective date of the Partnership Agreement, unless a later date has been specified (i.e., Equivalent
Energy Performance Amendment). This most recent version of the Program Requirements, Version 3.0,
supersedes all previous versions.

5) Future Criteria Revisions: ENERGY STAR reserves the right to change the specification should technological
and/or market changes affect its usefulness to consumers, industry, or the environment. Keeping with current
policy, industry/stakeholder discussions determine revisions to the criteria.

6) ENERGY STAR Criteria: To qualify in each ENERGY STAR Climate Zone products must have NFRC certified
U-Factor and, where applicable, Solar Heat Gain Coefficient (SHGC) ratings at levels which meet or exceed
the minimum qualification criteria specified in Table 1 and the ENERGY STAR Climate Zone Map on the
following page.

Equivalent Energy Performance Amendment (effective September 19. 2005): Allows windows and doors with
energy performance equivalent to the prescriptive criteria to qualify in the Southern and South/Central climate
zones, excluding California. Equivalent performance criteria are not applicable to the Northern and
North/Central climate zones or to skylights.

Skylights: Ratings produced under NFRC 1997 or NFRC 2001 may both be used to qualify window and door
products for ENERGY STAR. Skylights rated using NFRC 2001 procedures must meet the "2001 NFRC rated
at 20 degrees" skylight U-Factor qualification criteria. Skylights rated using NFRC 1997 procedures must have
ratings for the residential test and simulation size (RES97) that meet the "RES97 rated at 90 degrees" skylight
U-Factor qualification criteria.
