One of NFRC's main functions
is to promulgate technical standards that establish uniform procedures
for determining the various energy performance ratings; including
U-factor, SHGC (Solar Heat gain Coefficient), VT (Visible Transmittance)
and CR (Condensation Resistance).

For NFRC Certification of fenestration products, either WINDOW5/THERM5 or WINDOW6/THERM6 may be used for the simulation of those products. However, after July 1, 2011 only WINDOW6/THERM6 will be authorized for NFRC Certification.
Note:
Errata or addendums will be noted in the footer
of each documents. E.g. [E1A0] would mean that there is
