(34) Subsection R402.2 of the International Energy Conservation Code is amended to read <br /> as follows: <br /> "R402.2 Specific insulation requirements (Prescriptive). <br /> In addition to the requirements of Section R402.1, insulation shall meet the specific <br /> requirements of Sections 8402.2.1 through R402.2.13. <br /> Exception: Above-grade walls and ceilings shall be permitted to comply with <br /> Section R407." <br /> (35) Subsection R402.2.5 of the International Energy Conservation Code is amended to <br /> read as follows: <br /> "R402.2.5 Mass walls. Mass walls for the purposes of this chapter shall be <br /> considered above-grade walls of concrete block, concrete, insulated concrete form <br /> (ICF), masonry cavity,brick(other than brick veneer), earth (adobe, compressed <br /> earth block, rammed earth) and solid timber/logs, or any other walls having a heat <br /> capacity greater than or equal to 6 BtU/ft2 x'F (123 kJ/m2 x K). <br /> Exception: Insulation or R-value for mass walls, indicated in Table 8402.1.2, is <br /> not required when at least one of the following conditions is met: <br /> 1. Walls have a covering with a reflectance of> 0.64. <br /> 2. Walls have overhangs with a projection factor equal to or greater than 0.3. <br /> The projection factor is the horizontal distance from the surface of the wall <br /> to the farthest most point of the overhang divided by the vertical distance <br /> from the first floor level to the bottom most point of the overhang. <br /> 3. Concrete, CMU, and similar mass walls are 6 inches or greater in <br /> thickness." <br /> (36) Subsection R402.3.2 of the International Energy Conservation Code is amended to <br /> read as follows: <br /> "R402.3.2 Glazed fenestration SHGC. Fenestration shall have a maximum solar <br /> heat gain coefficient as specified in Table R402.1.2. An area-weighted average of <br /> fenestration products more than 50-percent glazed shall be permitted to satisfy the <br /> SHGC requirements. <br /> Exceptions• <br /> 1. Jalousie windows are exempt from SHGC requirements. <br /> 2. If fenestrations have overhangs with projection factors, the maximum <br /> solar heat gain coefficient shall be as specified in Table R401.2.1. <br /> Dynamic glazing shall be permitted to satisfy the SHGC requirements of Table <br /> R402.1.2 provided the ratio of the higher to lower labeled SHGC is greater than or <br /> 19 <br />
