Exterior lighting generally operates from early evening through early morning, a period of little to no renewable energy generation, which means this lighting is primarily powered by carbon-dense fossil fuels. Fossil fuel use is a significant contributor to greenhouse gas emissions (GHG), poor air quality, water pollution and land degradation. In addition, low-quality exterior lighting characterized by poor color, inappropriate light distribution, and inadequate light levels has also been linked to increased crime rates and reduced physical activity within the surrounding community.
CLTC and its partners, the California Energy Alliance and UC Irvine's California Plug Load Research Center, received $1M from the California Energy Commission to identify, test and recommend commercial and residential plug loads that present the best opportunity for energy savings as part of future energy codes and appliance standards.
The California Lighting Technology Center developed a series of lighting education videos in support of the 2019 Building Energy Efficiency Standards (Title 24). Videos cover four key topics:
In the fall of 2017, the Mexican Ministry of Energy awarded funding to the Universidad Autónoma de Guadalajara in collaboration with the University of California Davis to establish a lighting technology and design research center known as the Centro de Tecnología de Iluminación (CTI). This is a multi-year, public-private investment focused on addressing growing climate change concerns through translational research committed to clean energy and sustainability in Mexico.
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:
This Office Lighting course is designed for those who design, specify, or inspect lighting installations in new and remodeled commercial office spaces. The curriculum includes an overview of current lighting technologies, including LED luminaires, and updates on new lighting requirements and sections in the 2019 standards.
Learning outcomes for course participants include the ability to:
The California Energy Commission adopted new standards updating the Appliance Efficiency Regulations (Title 20) for lighting appliances. Updates rolled out in two tiers with Tier 1 effective January 1, 2018 and Tier 2 effective July 1, 2019. Notably, this update adds standards for small-diameter directional lamps. The updated regulations incorporate elements of lighting product quality for both general service LED lamps and small-diameter directional lamps in addition to the traditional lighting appliance efficiency standards previously included in the regulations.
Each year, California schools spend approximately as much money on energy—$700 million—as they do on books and supplies.1 Education spending is a frequent point of debate among politicians and citizens, and maximizing the implementation of energy efficient technologies in school facilities could act as a way to increase education budgets without allocating additional public funds.
