The California Lighting Technology Center partnered with Finelite, Inc. and Adura Technologies to develop and demonstrate a unique, wireless task/ambient office lighting solution ideally suited for the retrofit market. The system consists of two key elements: a task/ambient lighting system and advanced, wireless lighting controls. The combination substantially reduce energy use and improves lighting quality, and provides personal lighting control for individual work spaces, and does not require additional wiring or rewiring of existing luminaries or lighting circuits. The system has three specific components: adaptive ambient lighting, light-emitting diode task lighting, and wireless controls.

To maximize the respective benefits of open- and closed-loop systems, and minimize their limitations, the California Lighting Technology Center (CLTC) developed a dual-loop photosensor control system for skylight applications. The system features a control algorithm that monitors the open- and closed-loop photosensors and controls the electric light to provide the designed light level. It also automatically recalibrates nightly to adjust to long-term changes to the interior space. Results show the dual-loop technology delivers more consistent lighting and greater energy savings.
The California Energy Commission’s Public Interest Energy Research (PIER) Program sponsors the development and demonstration of energy-efficient building technologies. Over the past several years, PIER has developed strategic partnerships with the University of California, California State University, California Community Colleges, and California Department of General Services. These partnerships include a series of demonstration projects coupled with programmatic support to ensure continued deployment of energy-efficient technologies and practices across California. Examples of the latest energy-efficient innovations are described.
