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.
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.
The California Lighting Technology Center’s 2013 Outdoor Lighting Guide for Title 24, Part 6 compliance is designed to help builders, lighting industry professionals, and others navigate the nonresidential outdoor lighting portion of California’s Building Energy Efficiency Standards. The new standards, which took effect July 1, 2014, include updated requirements for retrofit standards, lighting controls, and uplight and glare limits.
In 2013, UC Santa Barbara partnered with the SPEED team to demonstrate network controlled LED lighting for streetlights and post-top fixtures. These exterior fixtures were purchased with dimming power supplies and equipped with radio frequency (RF) control modules. The post-top fixtures were also equipped with occupancy sensors. These lighting controls allowed all the units to be incorporated into an adaptive mesh network control system that optimized the fixtures’ energy efficiency and gave the campus unprecedented control of its lighting.
The Institutional-level Adaptive Controls for Exterior Lighting system incorporates exterior light points — pathways, building perimeters, parking lots, and roadways — into one smart, wireless system.
Originally launched as a pilot study, this system has since been installed for over 1,600 luminaires at the University of California, Davis.
An overview of SPEED Lighting Technologies at UC Santa Barbara.
Join UC Davis representatives, including staff from CLTC and WCEC, at this year's CHESC event hosted by UC Santa Barbara. Visit booth #203 to learn about lighting and HVAC innovations tested through the State Partnership for Energy Efficient Demonstrations (SPEED). Information on incentives and project financing options will also be available.
PIER sponsored research, development, and demonstration (RD&D) has focused on the combination of occupancy-based lighting controls and dynamically turnable light sources to create intelligent, bi-level luminaires for parking area applications.
The State Partnership for Energy Efficient Demonstrations (SPEED) program drives the market adoption of energy efficient technologies. Managed through the California Institute for Energy and Environment (CIEE), SPEED has conducted more than 100 demonstrations and other technology-transfer projects across the state, showcasing the benefits of best practices and state-of-the-art solutions.
Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
