NOTE: For Alterations to an existing home, submit a completed CF-1R-ALT Form.

Exception: Existing HVAC systems that are replaced or altered to serve the addition may be included on the CF-1R -ADD Form.

PRESCRIPTIVE ENVELOPE REQUIREMENTS FOR ADDITIONS

For standard wood and assemblies meeting the Cavity R-value only.

• For 100 ft2 additions; the Proposed values must be equal or greater than the Standard column or when indicated when using Package D, “Pkg D”. Enter values in the shaded Proposed Columns.

• For less than 1,000 ft2 additions must comply with “Pkg D” requirements unless indicated in the Standard Column. To meet “Pkg D” minimum energy compliance requirements, see RCM Appendix B, Table 151-C or §152(b) in the RCM. Enter values in the shaded Proposed Columns.

Note: For furred assemblies, accounting for Continuous Insulation R-value, see Page JA4-3 and Equation 4-1. For calculating furred walls use the Mass and Furring Construction table below.

FENESTRATION PROPOSED AREAS

Total

1. Fenestration area is the area of total glazed product (i.e. glass plus frame). Exception: When a door is less than 50% glass, the fenestration area may be the glass area plus a “2 inch frame” around the glass.

2. Enter value from Component Package D Requirements in Table 151-C.

3. Actual fenestration products installed and as indicated in CF-6R-ENV Form shall be equivalent to or have a lower U-factor and/or a lower SHGC value than that specified on the Fenestration Proposed Area table above.

4. Submit a completed WS-3R Form if a reduced SHGC is calculated with exterior shading.

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:
