Title 24

Title 24 is the energy efficiency building standard created by the California Energy Commission in 1978. Specifically, Part 6 – Section 118 of the code governs the requirements for installation of cool roofs.

From the California Energy Commission website:

Cool roofs are highly reflective, highly emissive roofing materials that stay 50 to 60 degrees F cooler than a normal roof under a hot summer sun.
Cool roofs can cut building owners' energy costs. Because cool roofs gain less heat than normal roofs, they reduce the need for air conditioning making buildings more comfortable to the people inside.
Cool roofs have other benefits, too. For building owners they can cut maintenance costs and increase the life expectancy of the roof. And for society in general, cool roofs can even help to reduce the urban heat island effect that makes our cities hotter and produces unhealthy air.
Because cool roofs save both money and energy, in October 2005 they became part of the prescriptive requirements of California's energy code, the Title 24 Building Energy Efficiency Standards. Most cool roof materials for low-sloped roofs are white or another light color. Because steep-sloped roofs are often visible from the ground, however, roofing material manufacturers have developed popular roof colors other than white that will still reflect or emit the sun's energy away from the building.
