Designing lighting for the WELL, Circadian Stimulus or European DIN SPEC 67600 models has its complexities. Until all lighting designers can achieve these goals, health and lighting will remain “the future." In this presentation, learn about a 2-year project to dynamically create field measurements of the non-visual aspects of lighting — lighting for health — through the creation of circadian heat maps. Through them we’ll all “see” the contribution of both ambient sunlight and artificial lighting to synchronizing our internal circadian rhythm. Why: better sleep, greater alertness, less depress and diabetes, from more light during the day, and less light at night.

Learning Objectives

  • Why is it so difficult to design lighting for health. The complexities of the different models will be explained in a way that makes sense.
  • Learn about circadian heat maps. Whether retrofitting or new construction, we now ‘see’ the non-visual benefits, design with knowledge, and lay out the space accordingly.
  • Lighting designers, manufacturers, space planners and building owners can now work together to ensure that building occupants receive the benefits of lighting for health.
  • Building owners and managers will have an opportunity to enrich their property offerings with a tenant improvement option that distinguishes their properties from the competition.

Business Development Manager, UL

Adam began in cancer research at Roswell Park Memorial Institute. After learning that the successes in the lab would take forty years to benefit patients, he committed his career to understanding why innovation adoption took so long. In advertising and marketing, Adam focused on new technologies, market drivers, and resistance to change.
As a result of the 9/11 tragedy, he started a life safety lighting company and worked to change the codes that limit their effectiveness. After, Adam designed and implemented LED lighting and advanced IoT controls in schools, offices and public spaces.
In his current role at UL, they anticipate the direction of the lighting market and build services for their customers. His focus has been light and health, UVC, photovoltaic and grow farm lighting.
