What is Cool Roof?
A cool roof (or energy efficient roof) reflects and emits the sun’s solar energy back to the sky instead of absorbing and transferring heat to the building below.
“Coolness” is measured by two properties, solar reflectance and thermal emittance. Both properties are measured from 0 to 1 and the higher the value, the “cooler” the roof.
California Title 24
The California Title 24 Building Energy Efficiency Standards are designed to ensure new and existing buildings achieve energy efficiency and preserve outdoor and indoor environmental quality.
California has 16 climate zones that represent a geographic area for which an energy budget is established.
Solar Reflectance Index (SRI)
Solar Reflectance Index (SRI) is a measurement that combines a surface’s solar reflectance and thermal emittance. SRI is an indicator of how well a surface reflects (reflectance) and releases absorbed solar radiation (emittance).
