Notes:
1. At the discretion of the Rater, the builder may verify up to eight items specified in this Checklist. When exercised, the builder's
responsibility will be formally acknowledged by the builder signing off on the checklist for the item(s) that they verified.
2. for Prescriptive Path: All windows, doors, and skylights shall meet or exceed ENERGY STAR Program Requirements for Residential
Windows, Doors, and Skylights - Version 5.0 as outlined at www_jine£gvst^^ For Performance Path: All windows, doors and
skylights shall meet or exceed the component U-factor and SHGC requirements specified in the 2009 lECC - Table 402.1.1. If no NFRC
rating is noted on the window or in product literature (e.g., for site-built fenestration), select the U-factor and SHGC value from Tables 4
and 14, respectively, in 2005 ASHFl'^E Fundamentals, Chapter 31. Select the highest U-faclor and SHGC value among the values listed
for the known window characteristics (e.g., frame type, number of panes, glass color, and presence of low-e coating). Note that the U-
factor requirement applies to all fenestration while the SHGC only applies to the glazed portion. The following exceptions apply:
a. An area-weighted average of fenestration products shall be permitted to satisfy the U-factor requirements;
b. An area-weighted average of fenestration products a 50% glazed shall be permitted to satisfy the SHGC requirements;
c. 15 square feet of glazed fenestration per dwelling unit shall be exempt from the U-factor and SHGC requirements, and shall be
excluded from area-weighted averages calculated using a) and b), above;
d. One side-hinged opaque door assembly up to 24 square feet in area shall be exempt from the U-factor requirements and shall be
excluded from area-weighted averages calculated using a) and b), above;
e. Fenestration utilized as part of a passive solar design shall be exempt from the U-factor and SHGC requirements, and shall be
excluded from area-weighted averages calculated using a) and b), above. Exempt windows shall be facing within 45 degrees of
true South and directly coupled to thermal storage mass that has a heat capacity > 20 btu / ft^x°F and provided in a ratio of at least
3 sq. ft. per sq. ft. of South facing fenestration. Generally, thermal mass materials will be at least 2 in. thick.
