Creating circadian-supportive environments, where each person’s 24-hour needs differ, can be a challenge under the best of circumstances, yet never more relevant than in today’s uncertain times.

Can circadian-effective lighting help promote health and wellbeing where we live and where we work?

Architects and lighting designers, whether in pursuit of knowledge as standard practice or seeking to achieve WELL points for their clients, often ask for guidance in understanding the issues regarding circadian light.

What are important factors to consider and what tools are available?

This presentation addresses basic circadian lighting principles and the consequences of circadian disruption, as well as current circadian metrics and lighting technologies at our disposal to facilitate the design of lighting that supports 24-hour schedules and spaces.

What you’ll learn:

1. How to recognize that there is a difference among people, their sensitivity, and their response to light depending on their location, profession, and schedules.
2.  Understand the different ways the visual system and non-visual system process light, and the impact on our 24-hour biological process.
3.  Explore the current circadian metrics, what they indicate, and the tools we can use to calculate them: circadian stimulus (CS), melanopic to photopic (M/P) ratio, equivalent melanopic lux (EML); as well as how they achieve points under the Circadian Lighting Design Category in WELL.
4.  How to compare lighting technologies that enable the creation of circadian-supportive lighting environments, from single-channel LEDs to biodynamic systems to multi-channel platforms; from simple to more complex – there are many ways to get there; it’s a matter of knowing the basic elements required and matching desired outcome to application.
