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.
The commercialization of Echelon's Lumewave MWX-LVE long-range outdoor microwave sensor illustrates CLTC's success in supporting advanced sensors for adaptive outdoor applications.
CLTC demonstrated and supported the next-generation sensor, which detects movement and can distinguish between slow and fast moving objects such as pedestrians, cyclists and motorized vehicles. The sensor reacts to the size of objects from longer distances, automatically raising the light levels to high output when the areas are occupied and lowering them when areas are vacant.
CLTC and the Bay Area Climate Collaborative (BACC) are working to educate Bay Area municipal leaders about streetlighting upgrades to reduce energy use and save money.
This in-depth workshop presented by the Bay Area Climate Collaborative and CLTC is for municipal leaders interested in learning about strategies for successful LED street and parking lighting upgrades. Municipal staff, area sustainability leaders and lighting professionals are encouraged to attend:
UC Davis News and Information—As ambulances at a Vacaville hospital speed off to their next patient, an ultrasmart, energy-efficient system is lighting the way. Installed in partnership with the University of California, Davis, the lighting system now illuminates the emergency vehicle routes, parking lots and outdoor walkways of the NorthBay VacaValley Hospital. The system is reducing outdoor lighting energy use at the 24-hour site by 66 percent, saving about 29,000 kilowatt-hours annually -- enough to offset the greenhouse gas emissions of 7.2 tons of waste.
LD+A – Multiple studies have demonstrated the significant energy savings that bi-level, occupancy-based lighting controls can achieve in outdoor applications. These controls maintain recommended illumination levels during occupied periods and automatically dim lights, reducing power by 50 percent or more, during vacant periods.
In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install a network-controlled adaptive outdoor LED lighting system. The hospital already had up-to-date, energy-efficient outdoor lighting installed, yet this award-winning installation reduced the hospital's outdoor lighting energy use 66.4%. Energy savings correspond to occupancy rates of 35–55% observed at different areas of the site.
In 2012, UC San Francisco launched a pilot demonstration of energy-efficient lighting on the top level of its two-tier parking garage on Post Street in San Francisco. That level of the parking structure had lacked lighting for some time, but a sharp increase in use prompted calls from nearby residents expressing safety concerns. CLTC and collaborators succeeded in delivering ultra-efficient lighting where and when it was needed while minimizing light trespass so as not to disturb residents of the apartment building next door.
Under California's latest Title 24, Part 6 standards, new installations of exterior lighting must be controlled by motion sensors. Adding the same adaptive features to the lighting already installed in parking lots throughout California could also achieve sizable energy and cost savings in a very short period of time.
