The California Lighting Technology Center at the University of California, Davis, has released a supplemental publication to the 2008 Residential Compliance Manual. The Title 24 Residential Lighting Design Guide is a resource of best practices and lighting designs to help builders, energy auditors and lighting designers comply with California’s 2008 Title 24 Building Energy Efficiency Standards, which went into effect Jan. 1, 2010.

The Residential Lighting Design Guide offers a technology overview for high-efficacy luminaires, switching controls, sensors and dimmers. It has a lighting design guide complete with room diagrams of several spaces in the home, and it includes an inspection and compliance checklist to help builders ensure homes are up to code.

The California Energy Commission’s updates to the Title 24 Part 6 standards include comprehensive changes for obtaining permits for residential lighting in new and remodeled homes. These standards will significantly reduce lighting energy consumption by requiring the use of energy-efficient technologies.

The code changes were adopted in response to California’s energy crisis to reduce energy bills, increase the reliability of energy delivery, and contribute to an improved economic condition for the state. The new code was based on how much energy the technology can save as well as the technology’s reliability, availability and cost-effectiveness. The code emphasizes measures that save energy during peak periods of power generation, such as hot summer days when air conditioners are running. It incorporates recent publicly funded research and increases the collaboration with California utilities to incorporate results of appropriate market-incentive programs for specific technologies.

The California Energy Commission and the Public Interest Energy Research program sponsored the development of the guide; the Sacramento Municipal Utility District and WattStopper, Santa Clara, Calif., supported a limited edition printing.
