Statewide Codes and Standards Market Adoption and Noncompliance Rates

For over thirty years, the California Energy Commission has worked to advance energy efficiency through promulgation of energy codes and standards for buildings and appliances known as Title 20 (appliances) and Title 24 (buildings). These standards are updated periodically to reflect the emergence of new energy-efficiency technologies and methods.

The California Statewide Codes and Standards Program (C&S Program, or Program) is implemented by the state’s investor-owned utilities and seeks to improve energy efficiency by influencing the periodic updates to the Title 20 and Title 24 standards. A consortium of representatives from each of the investor-owned utilities, called the Stakeholder Review Committee (SRC), works to propose the updates and monitor changes in energy use and market trends as a result of the codes. The most recent round of updates to the standards went into effect in late 2005 for the building standards, and in the period 2006-2008 for the appliance standards.
