Instructions: Use the tables below to determine the ENERGY STAR climate zones where your products qualify
and the appropriate ENERGY STAR product qualification label to use.
Prescriptive Qualification Criteria
If labeling windows and/or doors underthe prescriptive qualification criteria or labeling any skylight products
use the following two tables.

3	U-Factor qualification criteria based on
2001 NFRC simulation and certification
procedures that rate skylights at a
20-degree angle. Although reported
U-Factor is higher than RES97 rated
products, energy performance at the
ENERGY STAR minimum qualifying level
is equivalent.
4	NFRC certification using the 1997 NFRC
procedures for residential windows
(RES 97) that rated skylights at a 90-
degree angle. Skylights rated under
this procedure may be present in the
marketplace until March 31, 2008. NFRC
labels for products using this procedure
state: "RES97 rated at 90 degrees."
Equivalent Energy Performance Criteria (effective September 19,2005)
If iabeling windows and/or doors using the equivalent energy performance criteria, use the table below.
