Cavity insulation R-values shall not be used to determine compliance with the continuous insulation R-value requirements in WSEC Table C402.1.3. Commercial buildings or portions of commercial buildings enclosing Group R occupancies shall use the R-values from the "Group R" column of WSEC Table C402.1.3. Commercial buildings or portions of commercial buildings enclosing occupancies other than Group R shall use the R-values from the "All other" column of WSEC Table C402.1.3.
EXCEPTION: For stair and elevator shafts that do not comply with WSEC C402.1.2.1 and that are located within enclosed garages or other enclosed non-conditioned spaces and without conditioned supply air or cooling or heating appliances rated higher than 2 kilowatts in any shaft, walls enclosing the shafts are permitted to be:
1. Concrete or masonry with minimum R-5 continuous insulation;
2. Metal studs with R-15 cavity insulation and without continuous insulation; or
3. Other assemblies with a maximum U-value of 0.120.
Slab floors, intermediate mass floor edges, and elevator pits within shafts using this exception are excluded from envelope insulation requirements. Shaft surfaces using this exception shall not be included in the gross exterior wall area for purposes of maximum fenestration area calculations in WSEC C402.4.1 component performance calculations in WSEC C402.1.5, or for the total building performance calculation of WSEC C407.

Notes for Table C402.1.3(i):
1. These alternate nominal R-value compliance options are allowed for projects complying with all of the following:
1.a The ratio of the cross-sectional area, as measured in the plane of the surface, of metal penetrations of otherwise continuous insulation to the opaque surface area of the assembly is greater than 0.0004 (0.04 percent), but less than 0.0008 (0.08) percent for use of Column B equivalents, and greater than or equal to 0.008 (0.08) percent, but less than 0.0012 (0.12) percent, for use of Column C equivalents.
1.b. Where all metal penetrations are stainless steel, Column B is permitted to be used for penetrations greater than 0.12 percent, but less than 0.24 percent of opaque surface area, and Column C is permitted to be used for penetrations greater than or equal to 0.24 percent, but less than 0.48 percent of opaque surface area.
2. The metal penetrations of otherwise continuous insulation are isolated or discontinuous (e.g., brick ties or other discontinuous metal attachments, offset brackets supporting shelf angles that allow insulation to go between the shelf angle and the primary portions of the wall structure). No continuous metal elements (e.g., metal studs, z-girts, z-channels, shelf angles) penetrate the otherwise continuous portion of the insulation.
3. Building permit drawings shall contain details showing the locations and dimensions of all the metal penetrations (e.g., brick ties or other discontinuous metal attachments, offset brackets, etc.) of otherwise continuous insulation. In addition, calculations shall be provided showing the ratio of the cross- sectional area of metal penetrations of otherwise continuous insulation to the overall opaque wall area.
For other cases where the proposed assembly is not continuous insulation, see WSEC C402.1.4 for determination of U-factors for assemblies that include metal other than screws and nails.

NEW SECTION. SECTION 39. There is hereby added to K.C.C. chapter 16.07 a new section to read as follows:
Component performance alternative (WSEC C402.1.5). Building envelope values and fenestration areas determined in accordance with Equation 4-2 shall be permitted in lieu of compliance with the U-factors and F-factors in WSEC Table C402.1.4 and WSEC C402.4 and the maximum allowable fenestration areas in WSEC C402.4.1.
For buildings with more than one space conditioning category, component performance compliance shall be demonstrated separately for each space conditioning category. Interior partition ceilings, walls, fenestration, and floors that separate space conditioning areas shall be applied to the component performance calculations for the space conditioning category with the highest level of space conditioning.
High-performance vertical fenestration types required by Column B of WSEC Table C402.4 shall be calculated separately from other vertical fenestration types in Equation 4-2. The maximum U-factors permitted in Column B of WSEC Table C402.4 shall not be exceeded for the required Column B vertical fenestration area.
EXCEPTION: The maximum U-factor permitted for operable vertical fenestration in Column B of WSEC Table C402.4 may be exceeded when the Proposed Column B vertical fenestration area weighted UA is less than or equal to the Allowable Column B vertical fenestration area weighted UA for all types of Column B vertical fenestration.
Equation 4-2:
Proposed Total UA ≤ Allowable Total UA
Where:
Proposed Total UA = UA-glaz-prop + UA sky-prop + UA-opaque-prop + FL-slab-prop.
Allowable Total UA = UA-glaz-allow + UA-glaz-excess + UA sky-allow + UA-sky-excess + UA-opaque-allow + FL-slab-allow UA-glaz-prop = Sum of (proposed U-value × proposed area) for each distinct vertical fenestration type, up to code maximum
area.
UA-sky-prop = Sum of (proposed U-value × proposed area) for each distinct skylight type, up to the code maximum area UA-opaque-prop = Sum of (proposed U-value × proposed area) for each distinct opaque thermal envelope type.
FL-slab-prop = Sum of (proposed F-value × proposed length) for each distinct slab on grade perimeter assembly.
UA-glaz-allow = Sum of (code maximum vertical fenestration U-value from WSEC Table C402.4, or WSEC C402.4.1.1.2 if applicable, × proposed area) for each distinct vertical fenestration type, not to exceed the code maximum area1.
UA-glaz-excess = U-value for the proposed wall type from WSEC Table C402.42 × vertical fenestration area in excess of the code maximum area.
UA-sky-allow = Sum of (code maximum skylight U-value from WSEC Table C402.4 × proposed area) for each distinct skylight type proposed, not to exceed the code maximum area.
UA-sky-excess = U-value for the proposed roof type from WSEC Table C402.43 × skylight area in excess of the code maximum area.
UA-opaque-allow = Code maximum opaque envelope U-value from WSEC Table C402.1.4 for each opaque door, wall, roof, and floor assembly × proposed area.
FL-slab-allow = Code maximum F-value for each slab-on-grade perimeter assembly × proposed length.
Footnotes:
1. Where multiple vertical fenestration types are proposed and the code maximum area is exceeded, the U-value shall be the average WSEC Table C402.1.4 U-value weighted by the proposed vertical fenestration area of each type.
2. Where multiple wall types are proposed the U-value shall be the average WSEC Table C402.1.4 U-value weighted by the proposed above grade wall area of each type.
3. Where multiple roof types are proposed the U-value shall be the average WSEC Table C402.1.4 U-value weighted by the proposed roof area of each type.
SECTION 40. Ordinance 19485, Section 78, and K.C.C. 16.07.100 are hereby amended to read as follows:
Section C402.4 of the ((International Energy Conservation)) Washington State Energy Code is not adopted and the following is substituted:
Fenestration - prescriptive (((IECC)) WSEC C402.4). Fenestration shall comply with ((IECC)) WSEC C402.4 through C402.4.4 and IECC Table C402.4. Column A values in WSEC Table C402.4 apply to a maximum of 80 percent of the total building vertical fenestration area, or 65 percent to comply with Exception 1 to WSEC C402.4.1. The minimum 20 percent of fenestration required to meet the Column B high-performance U-factors, or 35 percent to comply with Exception 1 to WSEC C402.4.1, is permitted to be met using any combination of vertical fenestration types with Column B values listed, and those maximum U-factors must be maintained when using the component performance alternative in WSEC C402.1.5. An area-weighted average of Column B U-factors is permitted, in compliance with the exception to WSEC C402.1.5. Daylight responsive controls shall comply with this section and ((IECC C405.2.4)) WSEC C405.2.5.

NEW SECTION. SECTION 41. There is hereby added to K.C.C. chapter 16.07 a new section to read as follows:
Section C402.4.1 of the Washington State Energy Code is not adopted and the following is substituted:
Fenestration - Maximum area (WSEC C402.4.1). The total building vertical fenestration area (not including opaque doors and opaque spandrel panels) shall not exceed the percentage of above-grade wall area permitted by WSEC Table C402.4.1. The skylight area shall not exceed 5 percent of the total building gross roof area (skylight-to-roof ratio).
For buildings with more than one space conditioning category, compliance with the maximum allowed window-to-wall ratio and skylight-to-roof ratio shall be demonstrated separately for each space conditioning category. Interior partition ceiling, wall, fenestration, and floor areas that separate space conditioning areas shall not be ap-plied to the window-to-wall ratio and skylight-to-roof ratio calculations.
EXCEPTIONS:
1. The allowable total building vertical fenestration area in WSEC Table C402.4.1 is permitted to be increased by 5 percent where a minimum of 35 percent of all vertical fenestration complies with the high-performance fenestration required in Column B of WSEC Table C402.4.
2. For vertical fenestration at street level retail, the vertical fenestration area shall not exceed 75 percent of the area of the street-level wall that faces the street or that adjoins other pedestrian areas used for retail access. For the purposes of this exception, the street-level wall shall be measured from the street-level floor to the interior ceiling level or to 20 feet (6,096 millimeters) above floor level, whichever is lowest. When this exception is used, separate calculations shall be performed for these sections of the building envelope, and these values shall not be averaged with any others for compliance purposes. On the street level the 75 percent vertical fenestration area is permitted to be exceeded if the additional fenestration area is deducted from fenestration allowances from other areas of the building.
3. Accessory occupancy areas that comprise less than 10 percent of the conditioned floor area of any floor are permitted to be included in the primary occupancy of that floor for determination of the allowable fenestration area for that floor.
