Reflectance Ratings - American Buildings SRI is calculated by using the values of solar reflectance, thermal emittance and a medium wind coefficient. The higher the SRI value, the lower its surface temperature and consequently, the heat gain into the building. Cool metal roofs coated with the COOL-pigmented PVDF resin achieve an SRI of 25-88, depending on the color.
