R- values are minimums. U- factors and SHGC are maximums. R -19 shall be permitted <br />to be compressed into a 2 x 6 cavity. <br />b. The fenestration U- factor column excludes skylights. The SHGC column applies to all <br />glazed fenestration. <br />c. The first R -value applies to continuous insulation, the second to framing cavity <br />insulation; either insulation meets the requirement. <br />d. R -5 shall be added to the required slab edge R- values for heated slabs. <br />e. There are no SHGC requirements in the Marine zone. <br />f. Or insulation sufficient to fill the framing cavity, R -19 minimum. <br />g. "13 +5" means R -13 cavity insulation plus R -5 insulated sheathing. If structural <br />sheathing covers 25 percent or less of the exterior, insulating sheathing is not required <br />where structural sheathing is used. If structural sheathing covers more than 25 percent of <br />exterior, structural sheathing shall be supplemented with insulated sheathing of at least R- <br />2. <br />h. The ceiling insulation alternative in Section 402.1.1.1 can be used as an equivalent <br />alternative for R -30." <br />SECTION 4. Chapter 5, article 2, section 5- 2.1.1, Hawaii County Code 1983 (2005 <br />Edition, as amended), is amended by amending paragraph (6) of item (6) to read as follows: <br />"6. For compliance with Subsection 1.4, a cool roof shall have an infrared <br />[cmittance] emissivity of no [mere] less than 0.75 when tested in accordance with <br />ASTM E -408 and a high solar reflectance. Altematively, the corresponding Solar <br />Radiance Index (SRI) for a cool roof can be used. The manufacturer's test results <br />shall be acceptable for compliance. A cool roof has both a light color (high solar <br />reflectance) and a high [e mittance] emissivity (can reject heat back to the <br />environment).
