Connected: How Networked Control Systems (and codes and standards) Will Drive LED Adoption

09/18/2014

The LED Show 2014, Los Angeles, CA
Presented by Kelly Cunningham

Outreach Director Kelly Cunningham presented CLTC case study findings at The LED Show, September 16 in Los Angeles, CA. Attendees learned the results of indoor and outdoor lighting installations that paired LED sources with networked adaptive control systems. The presentation covered end-user feedback and data indicating energy savings of up to 90 percent.

University lights the way for hospital energy savings

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.

Shedding More Light on Occupancy

09/01/2014

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.

Performance Testing Report: Omni-directional LED Replacement Lamps

08/07/2014

A number of lighting manufacturers now produce LED replacement lamps for traditional 60W incandescent lamps, and stakeholders at the state and national levels face decisions regarding quality standards for this product category. To assist these stakeholders and assess the current state of this segment of the lighting market, CLTC performed photometric and electrical tests on samples of 26 commercially available A19 and A21 omnidirectional LED replacement products.

2014 DesignLights Consortium Stakeholder Meeting, San Diego
Presented by Michael Siminovitch​

On July 29, 2014, CLTC Director Michael Siminovitch gave a keynote address to those gathered for the annual DesignLights Consortium Stakeholder Meeting. The attached presentation begins with examples of wasteful lighting practices then explores control strategies and emerging technologies that have demonstrated deep energy savings. Case study results and information on UC Davis's Smart Lighting Initiative are included.

Campus-wide Networked Adaptive LED Lighting, UC Davis

07/23/2014

As part of its Smart Lighting Initiative, UC Davis undertook a campus-wide exterior lighting retrofit that involved installing over 1,500 network-controlled LED streetlights, area lights, post-tops, and wall packs. The “ultra-smart” lighting system has reduced the campus's exterior lighting energy use by 86% (1,231,758kWh annually), saving at least $120,900 in annual energy and maintenance costs.
