STANDARDS ENACTED BY THE STATE OF CALIFORNIA ENERGY COMMISSION APRIL 23, 2008 BECOMING LAW JANUARY 1, 2010
The most recent laws regarding energy conservation impacting roofing, ventilation and insulation are commonly referred to as Title 24 legislation. They were adopted by the state of California to combat smog, rampant energy consumption, and the inability to provide cooler summers and warmer winters to consumers homes and offices. The requirement for when the 2008 standards must be followed is dependent on when the application for the building permit is submitted. If the application for the building permit is submitted on or after 1/1/10, the 2008 standards must be met. The state of California adopted these standards for a number of reasons:
- To provide California with an adequate, reasonably-priced, and environmentally sound supply of energy.
- To respond to Assembly Bill 32, the Global Warming Solutions Act of 2006, which mandates that California must reduce its greenhouse gas emissions to 1990 levels by 2020.
- To pursue California energy policy
- To act on the findings of California’s Integrated Energy Policy Report
- To meet the West Coast Governors’ Global Warming Initiative commitment
- To meet the Executive Order in the Green Building Initiative to improve energy efficiency
***Not all roofing contractors can demonstrate their ability to conform to Title 24 State of California Roofing Standards. The new standards are law and you need to be aware of the new requirements BEFORE you hire a contractor.***

A Word from Owens Corning® About California's Title 24 “Cool Roof”
CHANGES IN ENERGY STANDARDS
Effective in August of 2009, shingles used in a roof must meet certain reflective qualities that help make your home more comfortable and energy efficient. Similar to energy-efficient appliances used in your home, a "Cool Roof" can provide energy saving qualities. Our Duration® Premium Cool shingles reflect solar energy, decreasing the amount of heat transferred to a home's interior thus using less air conditioning needed to keep it comfortable.
UNDERSTANDING TITLE 24, PART 6
Title 24 Part 6 is California's new energy efficiency standard. Its purpose is to reduce peak energy consumption in California, particularly the kind that contributes to rolling blackouts. Beginning in August of 2009, laws prescribe Cool Roofs on steep-slope new construction or re-roofs. Homeowners may qualify for rebates from PG&E when they install a Cool Roof. For more technical information please visit the Cool Roof Rating Council (CRRC) at www.coolroofs.org.
HOW IT WORKS
Cool Roofs reduce energy by using shingles with solar-reflecting granules that keep roofs cooler than convention shingles. Cool Roofs result in lower carbon dioxide emissions and help reduce the urban and suburban heat island effect which in turn reduces smog. Duration® PremiumCool shingles utilize a new, highly reflective granule technology that allows them to reflect the sun's heat, thereby reducing the heat transferred into the living space below. Another way to meet California's new law without installing Cool Roof is to bring your attic insulation up to a minimum R-30 by adding Pink Fiberglas™.
