SA = Solar Absorptance
BCA = The Building Code of Australia (BCA)
Thermal Values:
SA = Solar Absorptance
Solar Absorptance (SA) is a measure of how much of the sun’s heat that a material absorbs. Choosing a colour with a lower SA is a cooler option and may help to meet building regulations such as NCC or BASIX.
These are nominal values based on new product and measured in accordance with ASTM E 903-96. For further information refer to BlueScope Technical Bulletin TB 39 Thermal performance of roofing materials.
SRI = Solar Reflectance Index
Solar Reflectance Index (SRI) provides a guide of a surface’s ability to reject solar heat on the basis of the relative temperature of surfaces, with respect to a reference black (SRI=0) and white surface (SRI=100).
The SRI value of a surface is calculated from its solar reflectance and thermal emittance. These are nominal values based on new product and determined in accordance with ASTM E1980-11.
