DLC Stakeholders Meeting - Keynote Presentation

07/31/2014

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.

Adaptive Outdoor Lighting for the Health Care Sector

07/14/2014

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.

 

Networked Adaptive Parking Lot Lighting

07/02/2014

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.

SPEED Business Case: Adaptive Street and Area Lighting

06/13/2014

This business case explores various lighting control options for LED retrofits of street and area lighting, along with funding and financing sources. It provides a general economic analysis of the costs and benefits associated with street/area retrofits and new-construction installations of post-top luminaires. The scenarios presented in this business case analysis have the potential to reduce lighting energy use and carbon emissions 72–93%, in areas with an average occupancy rate of 20%.
