In commercial <br />buildings, an area -weighted average of fenestration products <br />shall be permitted to satisfy SHGC requirements. <br />Exception: Jalousie windows are exempt from SHGC <br />requirements." <br />(13) Subsection C402.5 of the International Energy Conservation Code is <br />amended to read as follows: <br />"C402.5 Air leakage -thermal envelope (Mandatory). <br />The thermal envelope of buildings shall comply with Sections <br />C402.5.1 through C402.5.8, or the building thermal envelope <br />shall be tested in accordance with ASTM E 779 at a pressure <br />differential of 0.3 inch water gauge (75 Pa) and deemed to <br />comply with the provisions of this section when the tested air <br />leakage rate of the building thermal envelope is not greater <br />than 0.40 cfm/ft2 (0.2 L/s • m2). Where compliance is based on <br />such testing, the building shall also comply with Sections <br />C402.5.5, C402.5.6 and C402.5.7." <br />5-115 SUPP. 8 (7-2020) <br />
