408.3.1.2 Solar Reflectance Index

Green Construction Code 2012 > 4 Site Development and Land Use > 408 Heat Island Mitigation > 408.3 Roof Surfaces > 408.3.1 Roof Coverings—solar Reflectance and Thermal Emittance > 408.3.1.2 Solar Reflectance Index
JUMP TO FULL CODE CHAPTER
Roof products shall be permitted to use a solar reflectance index (SRI) where the calculated value is in compliance with Table 408.3.1 values for minimum aged SRI. The SRI value shall be determined using ASTM E 1980 with a convection coefficient of 2.1 Btu/h-ft2 (12 W/m2 × k) based on three-year aged roof samples tested in accordance with the test methods in Section 408.3.1.1.
