Dynamic glazing shall be <br /> considered separately from other fenestration, and area-weighted averaging with other <br /> fenestration that is not dynamic glazing shall not be permitted. <br /> Exception: Dynamic glazing is not required to comply with this section when <br /> both the lower and higher labeled SHGC already comply with the requirements of <br /> Table R402.1.2." <br /> (37) Subsection R402.4.1.2 of the International Energy Conservation Code is amended to <br /> read as follows: <br /> "R402.4.1.2 Testing. The building or dwelling unit [shall] may be tested and verified <br /> as having an air leakage rate not exceeding five air changes per hour in Climate <br /> Zones 1 and 2, and three air changes per hour in Climate Zones 3 through 8. Testing <br /> shall be conducted in accordance with ASTM E 779 or ASTM E 1827 and reported at <br /> a pressure of 0.2 inch w.g. (50 Pascals).
