California’s Building Energy Effi ciency Standard—also known as Title 24, Part 6—is now in effect. The new standard calls for increased energy effi ciency in homes and commercial buildings. The easiest way for many consumers and business owners to meet the new standard is to choose “cool roof” shingles when installing a new or replacement roof.

Shingles that qualify as cool roof shingles feature highly reflective color granules that help lower energy bills by keeping roofs cool.* They also meet the criteria set by the experts at the Cool Roof Rating Council (CRRC). The California Energy Commission (CEC) has established prescriptive requirements that asphalt shingles on steep-sloped roofs in Climate Zones 10–15

must have a minimum calculated 3-year aged reflectance of .20, a minimum emittance of .75 and a minimum Solar Reflectance Index of 16.

Owens Corning™ Roofi ng offers many high-performance shingles that meet Title 24, Part 6, requirements:

* Estimated roof surface temperature reduction based on 1998 NIST study, Analytical Study of Residential Buildings with Reflective Roofs. A temperature reduction is representative of a change from a typical roof to a Cool Roof (solar reflectance 0.10 to 0.25) in most climates.
