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.
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:
Traditional outdoor lighting technologies operate at full power throughout the night, even when areas are vacant. This extra load, energy waste and light pollution can be averted by updating the lighting system with energy-efficient light sources and lighting controls. By installing these technologies, adaptive lighting strategies can be implemented that provide the right amount of light when and where it is needed.
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 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.
CLTC, in collaboration with the Office of Naval Research, developed new, improved strategies and technologies for occupancy sensing in outdoor applications that address the shortcomings of existing strategies and technologies. The project approach included the systematic identification of the pros and cons of existing strategies and technologies, formulation of new strategies and/or technologies, and implementation of new approaches in the form of laboratory prototypes that will be tested and demonstrated in the laboratory and in the field.
The California Lighting Technology Center partnered with San Diego Gas & Electric and two Southern California cities on a project to help accelerate the adoption of energy-efficient advanced outdoor lighting control systems.
The project evaluated outdoor wireless lighting control systems that allows for remote operation and monitoring of fixtures using a web-enabled central management system. Laboratory and field assessments were conducted for separate systems installed as part of citywide retrofit projects in San Diego and Chula Vista.
The UC Davis Smart Lighting Initiative was established in 2010 to improve the quality and efficiency of both indoor and outdoor lighting on campus. The initiative's primary goal is to reduce UC Davis's electricity use for lighting by 60 percent, based on 2007 levels of energy use. The effort was inspired by the California Public Utilities Commission (CPUC) and its call to reduce statewide electricity consumption for lighting by 60 percent or more by 2020.
