Interior lighting remains a large component of electricity use in non-residential buildings. In California, electric lighting has both a direct effect on peak load, and an indirect effect by increasing cooling requirements during summer peak hours. Effective daylighting combined with electric lighting dimming controls can directly offset electric lighting energy by reducing lighting levels when necessary to reduce the load on the cooling system.
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.
This presentation includes best practices in residential lighting design to comply with California's 2019 and 2022 Title 24, Part 6 Building Energy Efficiency Standards.
This presentation includes best practices in nonresidential lighting design to comply with California's 2019 and 2022 Title 24, Part 6 Building Energy Efficiency Standards, with specific examples included for office lighting projects.
The Consortium for Energy Efficiency in Non-Residential Buildings (The Consortium), supported by the National Council for Science and Technology and Secretary of Energy in Mexico, is focused on reducing electricity demand in Mexico’s non-residential buildings through collaborative efforts with industry, government and universities. Specifically, the Monterrey Institute of Technology and Higher Education, with assistance from UC Davis, is funded to implement an energy efficiency laboratory featuring lighting and air conditioning technologies for non-residential buildings.
The CLTC is excited to announce a new publication in our Lighting Best Practices series, the Daylight Harvesting for Commercial Buildings Guide! This publication provides guidance towards meeting and exceeding California's Building Energy Efficiency Standards for daylight harvesting.
Heading to the lighting aisle soon? Keep these key factors in mind when selecting your new light source:
Good retail lighting presents the store’s merchandise in a way that makes shopping a comfortable and engaging experience. In most retail applications, this involves maximizing illumination while minimizing the visibility of light sources. This allows customers to focus on what is being lit, versus the lighting itself. These modules are training materials for the Title 24 Retail course. This intermediate class is for professionals who design, specify, and/or inspect lighting installations in new and remodeled retail spaces.
The Residential Lighting Design Guide outlines best practices in lighting design to help builders comply with California's 2019 Title 24 Energy Standards requirements.
- Explanation of the code
- Technical and compliance information
- Lighting design examples
The lighting design guide will cover code explanation and floor plan examples of the following areas:
