As members of the lighting community, we keep hearing about WELL standard everywhere. There has been an explosion of interest in the idea of buildings as health intervention tools. The new standard focusing on human health crossed the 205 million square feet threshold for registered and certified projects in 39 countries around the world and it is becoming a popular trend in the building industry.

One chapter of WELL standard is dedicated to lighting. It provides guidelines for minimizing disturbance to human body’s circadian system, increasing productivity and providing appropriate visual acuity. The new version of WELL (i.e., V2) provides more flexibility and options for lighting designer to illuminate a ‘WELL lit’ space.

WELL defines new standards for visual comfort and it adapts new metrics for circadian rhythm lighting. Achieving these goals would only be possible by specifying pertinent products for each application. Although these guidelines are pretty straightforward, and it’s been about 1 year since the release of V2, it seems that gathering all required data is not easily feasible for lighting designers. Despite the high demand, many lighting manufactures don’t provide all the required information that lighting designers need for specifying right fixtures for WELL projects.

This seminar gives an overview of the lighting requirements in WELL standard and it will focus on key factors that lighting designers need to consider before specifying lighting fixtures. It provides practical recommendations and strategies for both lighting designers and manufacturers who are interested in WELL or are working on a project pursuing WELL certification.
