§ 5E-2-1 H AWAI‘I C OUNTY C ODE <br />(35) TABLE R402.1.2 of the International Energy Conservation Code is deleted in <br />its entirety and replaced with the following: <br />“TABLE R402.1.2 <br />a <br />INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENT <br />CLIMATE FENES-SKYLIGHT GLAZED CEILING WOOD MASS FLOOR BASEMENT SLAB CRAWL <br />bd <br />ZONE TRATION U-FACTOR FENES- R-VALUE FRAME WALL R-VALUE WALL R-VALUE SPACE <br />e, f <br />U-TRATION WALL R-VALUE R-VALUE & DEPTH WALL <br />bb, c, gd <br />FACTORSHGC R-VALUE R-VALUE <br />1 NR 0.75 0.25 3013 3/4 000 0 <br />For SI: 1 foot = 304.8 mm <br />a. R-values are minimums. U-factors and SHGC are maximums. When insulation is <br />installed in a cavity which is less than the label or design thickness of the <br />insulation, the installed R-value of the insulation shall not be less than the R- <br />value specified in the table. <br />b. The fenestration U-factor column excludes skylights. The SHGC column applies to <br />all glazed fenestration. Exception: Skylights may be excluded from glazed <br />fenestration SHGC requirements in climate zones 1 through 3 where the SHGC <br />for such skylights does not exceed 0.30. <br />c. Exception: If fenestration have overhangs with projection factors, the maximum <br />solar heat gain coefficient shall be as specified in Table R401.2.1. <br />d. R402.1.2 and R402.2 allow use of R407. <br />e. The second R-value applies when more than half the insulation is on the interior <br />of the mass wall. <br />f. Exception: R-value for mass walls are not required if: mass walls have a covering <br /> mass walls have overhangs with a projection factor <br />equal to or greater than 0.3. CMU or similar mass walls are 6 inches or greater in <br />thickness. <br />g. Exception: Jalousie windows are exempt from SHGC requirements.” <br />(36) Subsection R402.1.2 of the International Energy Conservation Code is <br />amended to read as follows: <br />“R402.1.2 Insulation and fenestration criteria (Prescriptive). <br />The building thermal envelope shall meet the requirements of Table <br />R402.1.2, <br />Exception: Insulation values of above-grade walls and ceilings shall <br />be permitted to comply with Section R407.” <br />SUPP. 9 (1-2021) <br /> <br />5E-18 <br /> <br />
