question whether they will have
NFRC labels. The following are
acceptable methods under the
2015 IECC to verify fenestration
U-factors as part of the building
thermal envelope. If not
providing NFRC labels for all
exterior doors and windows
(option 1), clarify how you will
document compliant U values:
1.NFRC certification; label
applied to window assembly and
verified at field inspection.
2.Default values from 2015 IECC
tables C303.1.3(1)C303.1.3(2),
R303.1.3(1), and R303.1.3(2).
3.Default values from Table 4
U-Factors for Various
Fenestration Products in 2013
ASHRAE Fundamentals
Handbook chapter 15, pg. 15.3.
To document the chain of
custody, a certificate, affidavit or
other evidence from the
manufacturer confirming
compliance with the above
method is required.
4.Calculation methods in 2013
ASHRAE Fundamentals
Handbook chapter 15, pg. 15.3:
"U-Factor(Overall Coefficient of
Heat Transfer)".A calculation is
required for the standard NFRC
window size of 47.2"x 47.2".To
document the chain of custody,
a certificate, affidavit or other
evidence from the manufacturer
confirming compliance with the
above calculation is required.
5.U-ratings by an
NFRC—accredited lab in
accordance with NFRC-100. To
document the chain of custody,
verification labels affixed to the
units by an accredited
independent inspection agency
or a certificate, affidavit or other
evidence from the manufacturer
confirming compliance with the
above simulation or testing.
