Title 24 is a collection of energy standards for California buildings that began in 1978 as air quality stressed the power grids and heat buildup in urban areas became significant.
Birth of the “Cool” Roof
The major focus of Title 24 was to establish requirements for roofing products that would substantially reduce heat absorption by increasing the reflective characteristics of the roof shingles and tiles. This initiative led to the development of the industry term “cool roof.”
So What Are the Requirements to Be A “Cool Roof” Product?
Part 6 of Title 24 lays out these roofing requirements:
- Thermal emittance – The ability of a roof shingle to release any heat that it has absorbed.
- Three-year aged reflectance – A measurement of a roof tile’s ability to reflect heat away from itself after 3 years.
- Solar reflective index – The ability of a roof shingle to reflect solar heat as measured by a small rise in temperature.
Brava Cool Roof Products
