Assembly Alteration

Opening of framed cavity alone – Alterations that involve the opening of the framed cavity of a wall, ceiling, or floor must install the mandatory minimum insulation value per §150 for the altered assembly. Fill in Columns A –C and enter mandatory insulation value in Column H.

Replacement of entire assembly – Replacement of an entire wall, ceiling, or floor assembly requires the installation of Component Package- D insulation values in Table 151-C. Fill in Columns A – J.

Opaque Surface Details For the furred portioned of Mass Walls see Furring Strips Construction Table below.

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.

1.For Tag/ID indicate the identification name that matches the building plans.

2.Indicate the Assembly Name or type: Roof/Ceiling, Walls, Floors, Slabs, Crawl Space, Doors and etc…Indicate the Frame type and Size: For Wood, Metal, Metal Buildings, Mass, enter 2x4, 2x6, or etc… see JA4 for other possible frame type assemblies.

3.Enter the thickness for mass in inches or Spacing between framing members enter; 16”or 24”OC; or Other for all other assembly description such as Concrete Sandwich Panel, Spandrel Panel, Logs, Straw Bale Panel and etc….

4.Based on the Climate Zone; enter the Standard U-factor from Table 151-B, C or D for each different assembly Name or type.

5.Enter the Table number that closely resembles the proposed assembly.

6.Enter the R-value that is being installed in the wall cavity or between the framing; otherwise, enter “0”.

7.Enter the Continuous Insulation R-value for the proposed assembly; otherwise, enter “0”.

8.Enter the row and column of the U-factor value based on Column F Table Number and enter the Assembly U-factor in Column J

9.The Proposed Assembly U-factor, Column J, must be equal to or less than the Standard U-factor in Column E to comply.

Mass and Furring Strips Construction (footnotes)

1.Indicate the type of assembly to include; Hollow Unit Masonry Walls, Solid Unit Masonry, Solid Concrete Walls, Etc. Additional assemblies can be found Reference Joint Appendix JA4.

2.This is the U-Factor based on the thickness of the assembly in inches.

3.The R-value of the insulation to be added on the interior or exterior of the assembly.

4.The Calculated R-Value is the R-value of the furred out section of the assembly.

5.-6.The Final Assembly is calculated using Equation 4-2 or Equation 4-4of the Reference Joint Appendix JA4. The equation is the inverse of Column D added to Column I. Column K is the inverse from column J.

7. Insert the calculated U-factor value on to the Opaque Surface Details in Column J

FENESTRATION PROPOSED AREAS

Replacing window alone – Replacement windows shall meet the U-Factor and SHGC Value requirements of Component Package D in Table 151-C. The Total Fenestration and West-facing Area requirements are not applicable.

Adding 50ft2 or less of window area – Newly installed windows shall meet the U-Factor and SHGC Value requirements of Component Package D in Table 151-C.

Adding more than 50ft2 of window area – Newly installed windows shall meet the U-Factor and SHGC Value and the Fenestration Area requirements of Component Package D in Table 151-C. Complete the Altered Fenestration Allowed Area Table on Page 2 of the CF-1R-ALT

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 CF-1R ALT Form.

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

5.If applicable at this stage enter “NFRC” for NFRC Certified windows or are CEC “Default” values found in Table 116-A or B.

ALTERED FENESTRATION ALLOWED AREAS (Complete if more than 50ft2 of fenestration is added)

1.West Fenestration Area includes west-sloping skylights and any skylights with a pitch less than 1:12.

2.West facing glazing area removed cannot be “counted” twice.” In order to distribute the west glazing area removed to the other orientations, input the west glazing area removed in the Total Fenestration Area row, column D.

3.Include the Proposed Area of the West facing fenestration in both Area columns below.

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

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

When the area of exterior roof surface to be replaced exceeds more than 50% of the existing roof area, or more than 1,000 ft2, whichever is less, the new roofing area must meet the roofing product “Cool Roof” requirements of §152(b)1Hi, 152(b)1Hii, or 152(b)1Hiii.

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