The California Lighting Technology Center’s Nonresidential Lighting and Electrical Power Distribution Guide assists builders and lighting industry professionals in navigating the nonresidential lighting and electrical power distribution portions 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.
Significant changes in the 2019 Energy Code address ventilation, HVAC, demand response and lighting. Notably, the 2019 Energy Code now include requirements for healthcare facilities (Occupancy Group I-2), although there are many exceptions for this building type. Major changes to the nonresidential lighting portion of the Energy Code include:
- Lighting Power Allowances
- Power Adjustment Factors
- Additions, Alterations & Repairs
This guide includes an explanation of the requirements for nonresidential lighting and electrical power distribution, as well as detailing best-practice recommendations with examples. The new guide also includes information on current lighting technologies, energy-efficient lighting strategies and lighting design principles.
The Nonresidential Lighting and Electrical Power Distribution Guide is sponsored by Energy Code Ace and developed in collaboration with the California Energy Commission. It complements the California Energy Commission's Nonresidential Compliance Manual as well as energy education classes on residential lighting offered through Pacific Gas & Electric and Southern California Edison.
