Biological rhythms that repeat approximately every 24 hours are called circadian rhythms. Light is the main stimulus that helps the circadian clock, and thus circadian rhythms, to synchronize with the 24-hour day. If lack of synchrony or circadian disruption occurs, we may experience decrements in physiological functions, neurobehavioral performance, and sleep.
Lighting for the circadian system employs lighting design objectives that differ from those typically used in traditional architectural lighting design, and therefore, requires metrics that differ from those currently used by lighting designers.
A summary of the lab and field research will be presented along with practical design solutions to increase the potential for circadian light exposure in buildings.
The goal of this presentation is to provide attendees with research findings together with new tools and metrics that will help them specify and apply effective lighting to improve lighting in our living environments.
