1.The Proposed West Fenestration Area includes West-sloping skylight area and any other skylight area with a pitch less than 1:12.

2.Enter 20% when no West orientation restriction or 15% when West fenestration is being installed in Climate Zones 2, 4, & 7-15.

3.Fenestration area removed to make way for the addition. For additions less than 1,000 ft2 the standards allows glazing removed during the remodel to be added to the glazing area allowance. The maximum allowed glazing area for the addition is CFA x (15% or 20%) + glass removed to make way for the addition.

4.In climate zones 2, 4, 7-15, no more than 5% of the CFA is allowed for west-facing glazing plus west-facing glass area removed to make way for the addition. The maximum allowed west-facing glazing area is the CFA x 5% + west-facing glass removed to make way for the addition.

5.To meet energy compliance, the Proposed Area must be less than or equal to the Allowed Area for BOTH the Total and West Fenestration Areas.

ROOFING PRODUCTS (COOL ROOFS) §151(f)12

Check applicable box below if the roof addition is exempt from the roofing product “Cool Roof” requirements. Note: If any one of the boxes are checked below, the Aged Solar Reflectance and Thermal Emittance requirements for roofing products in §118(i) are not applicable. Do not fill table below.

Roofing compliance Not Required in Climate Zones 1-12, 14, and 16 with a Low-Sloped. Less or 2:12 pitch.

Roofing compliance Not Required in Climate Zones 1 through 9 and 16 with a Steep-Sloped. Roofs pitch greater than 2:12 and product weight less than 5lb/ft2.

Roofing area covered by building integrated; photovoltaic panels and solar thermal panels are exempt from the above Cool Roof criteria Roof constructions that have thermal mass over the roof membrane with at least 25 lb/ft2 is exempt from the above Cool Roof criteria.

Note: If no CRRC-1 label is available, this compliance method cannot be used, use the Performance Approach to show compliance, otherwise, check the applicable box below if Exempt from the Roofing Products “Cool Roof” Requirement:
