Adaptive Lighting for Energy-Efficient Comfort and Wellbeing

Publication Date: 

Adaptive lighting refers to electric lighting sources that automatically adjust their output based on environmental changes, aiming at maximizing comfort, wellbeing and energy efficiency.  This presentation provides an overview of the concept, focusing on adaptive lighting controls based on sensing occupancy and daylight. The overview reflects the adaptive lighting research, development and demonstration efforts of the California Lighting Technology Center.

The adaptive lighting efforts were initiated in 2003 and continue today, having produced significant results and multiple commercial products. The goal of the efforts is to maximize electric lighting savings by automatically controlling electric lighting based on occupancy and daylight. The focus is on strategies and technologies to improve performance in terms of reliability and cost-effectiveness for wide-spread use in outdoor and indoor spaces of new and existing buildings.
