Campus Lighting Retrofit Forum

CLTC and co-host UC Irvine invite campus energy and facility managers from the UC/CSU/CCC and DGS systems to join us for the Campus Lighting Retrofit Forum to exchange information about
energy-saving lighting technologies.

Attendees will have opportunities to meet with colleagues and manufacturers to discuss ideas and projects. Presentations given by facility managers and campus leaders will include exterior lighting, office workspaces, classroom buildings, and demonstration installations. Case studies will show the results of projects that have recently been installed, providing peer feedback on the performance of emerging technologies, energy savings, funding opportunities, and how the project was received by the campus community.

There is no fee to attend the event, but space is limited. REGISTER NOW

WHO SHOULD ATTEND Campus facility managers, energy managers, engineers, and sustainability experts

WHERE July 1 at UC Davis & July 13 at UC Irvine		WHEN 8:30 am – 5 pm

For the agenda, exhibitors, and other information, visit the forum website here.

Innovative Watt Stopper/Legrand Daylighting Controller Features CLTC Technology

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

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.

January 12, 2009 marked the ribbon cutting of the Bi-level Smart LED Parking Lighting Technology at UC Davis' South Entry Parking Structure top deck. Fifty LED parking fixtures manufactured by BetaLED featuring technology researched and developed by CLTC have been installed at the parking structure.

This event also marks the University of California, Davis' induction into LED University, an initiative organized by Cree, Inc. to promote LED lighting technology to campuses to save energy, reduce maintenance costs, and improve visibility and safety.
