Solar Reflectivity (R) & Solar Reflectance Index (SRI) by

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color. Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total reflectance.

But Yellow Tactiles on Concrete Comply….. Dont They?

Concrete being a surface common in our everyday environment. The LRV test, conducted as per the methodologies prescribed in AS 1428.1- Appendix B and AS/NZS 1428.4.1- Appendix E, confirmed our suspicion that some "yellow' tiles whilst achieving the required 30% luminance contrast in a wet situation do not achieve the same in a dry condition. Thereby not achieving compliance for

Solar reflectance determines the fraction of the solar radiation incident from all directions that is diffusely reflected by the surface. The higher the solar reflective value the more efficient the product is in reflecting sunlight and heat away from the building and reducing roof and wall temperature.
