2009 CLTC Campus Lighting Retrofit Forum





The 2009 CLTC Campus Lighting Retrofit Forum, co-hosted by UC Irvine, was held on July 1 at UC Davis and July 13 at UC Irvine. The forum provided the opportunity for researchers, manufacturers, and energy managers to forge connections and update their knowledge on current campus lighting practices. Panels of experts gave presentations and led discussions on general lighting practices, financing, and campus case studies. CLTC Affiliate Manufacturers showcased various technologies for use in campus lighting retrofits. The feedback from the forum has been overwhelmingly positive and hosted over 150 participants at each location.

UC Davis and Cal Poly SLO Win Best Practice Award for Campus Lighting Projects

Two energy efficient campus lighting retrofit projects initiated by CLTC were selected for Energy Efficiency Partnership Program Best Practice Awards. The awards were presented at the 8th annual CCC/CSU/UC Sustainability Conference at UC Santa Barbara to Cal Poly San Luis Obispo Sustainability Manager, Dennis Elliot and to UC Davis Associate Director of Facilities Management, Chris Cioni for their campus lighting retrofit projects.

This award demonstrates the state-wide potential for continued improvement in energy efficiency and sustainable practices on campuses through the exchange of information and case studies. For more information on campus projects, see the Campus Lighting Retrofit Forum archive of this site. For more information on the PIER demonstrations projects presented at the 2009 UCSB Sustainability Conference, review the PIER/CIEE Sustainability Conference web site.

CLTC Moves to a New Facility

In 2004, California Lighting Technology Center began as a vision and an empty building. Professors Michael Siminovitch and Konstantinos Papamichael, three staff members, and a few student interns created the foundations of CLTC's research, education, and outreach mission.

Five years later and with an affiliate partnership program representing over half of the total sales of the US lighting industry, CLTC had outgrown the space on Drew Avenue. CLTC now includes over thirty employees consisting of professors, full-time staff, graduate student researchers, and student interns. At the start of July, the transition to the new location commenced.

CLTC's new location is more than twice the size of our previous space to accomodate our growing staff and multiple demonstration areas. The next few months will include the construction of new demonstration displays and interior rennovations to suit education, research and meeting purposes. A grand re-opening event is planned for the Fall. Sign up for our newsletter to receive an invitation to this event.

Innovative Watt Stopper/Legrand Daylighting Controller Features CLTC Technology


From the Lab Simplified Daylight Harvesting testing laboratory prototype, July 2005		To the Marketplace Watt Stopper/Legrand LS-102 Daylighting Controller Courtesy: Watt Stopper/Legrand
Watt Stopper/Legrand announced the launch of the LS-102 Daylighting Controller in February 2009, the first of a series of daylight harvesting control products that use innovative technologies developed at CLTC with support from the California Energy Commision's Public Interest Energy Research (PIER) Program. The LS-102 Daylighting Controller is the first of a series of daylight harvesting control products that greatly increase reliability and decrease costs by providing continuous, automatic calibration, overcoming one of the most prominent barriers in wide-spread daylight harvesting, i.e., the need for recalibration after changing interior surface geometry or reflectance. CLTC Associate Director Konstantinos Papamichael made the following statement: "I am very excited to see this technological innovation in a commercial product. Automatic, continuous calibration is key to successful photo sensor based daylight harvesting controls, which are most important to reducing energy requirements and peak electricity demand. It has been a pleasure working with Watt Stopper/Legrand and we look forward to continuing the collaboration towards additional products. Many thanks to the California utilities for identifying the market need for a simplified daylight harvesting control system and the California Energy Commission's PIER Program and the University of California, Davis, who supported the development of the new technology. Visit our projects page for more information about CLTC's Simplified Daylight Harvesting Technology.

Self Commissioning Dual Loop Sensor Dimming Technology Installed at Wal-Mart in West Sacramento


Self Commissioning Dual Loop Sensor		Wal-mart skylights , West Sacramento

CLTC partnered with Wal-Mart and Watt Stopper/Legrand to accelerate the commercialization of the Self Commissioning Dual Loop Sensor Dimming Technology for Daylight Harvesting. After successful testing in the laboratory, a prototype dual loop system has been installed on the western side of the West Sacramento Wal-Mart store, over the home and garden section. The rest of the store is controlled by the originally installed single sensor, open loop control system. CLTC is gathering data from both systems to quantify the performance improvements of the dual loop system compared to the single sensor system. Initial results show significantly increased accuracy and reliability. For more information about the Dual Loop Sensor demonstration, view the project page here.
