Publication Date: 
03/25/2020

The California Lighting Technology Center’s Residential Lighting Guide assists builders and lighting industry professionals in navigating the residential lighting portion of California’s Building Energy Efficiency Standards (Title 24, Part 6 or Energy Code). The 2019 iteration of the Energy Code took effect on January 1, 2020. 

Single-family homes built under the 2019 Energy Code will use about seven percent less energy due to the new energy efficiency measures as compared to homes built under the 2016 Energy Code.  Once rooftop solar electricity generation is factored in, homes built under the 2019 Energy Code will use an estimated 53 percent less energy than those under the 2016 Energy Code.

This guide includes an explanation of the requirements for residential lighting and details best-practice recommendations with sample lighting plans. The new guide also includes information on current lighting technologies, energy-efficient lighting strategies and lighting design principles.

The Residential Lighting Guide is sponsored by Energy Code Ace and developed in collaboration with the California Energy Commission. It complements the California Energy Commission's Residential Compliance Manual as well as energy education classes on residential lighting offered through Pacific Gas & Electric and Southern California Edison.
