Mark ReaMark S. Rea, Professor of Architecture and Cognitive Sciences at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, has agreed to chair a task group with Underwriters Laboratories Inc. (UL) working to develop a recommended practice for the specification, measurement and application of lighting to support circadian entrainment of individuals in daytime work environments.

The task group will produce a set of practical recommendations and methods, grounded in science, that can be broadly implemented by addressing how to specify lighting for daytime applications, how to accurately measure circadian light, and how specification can be achieved, not only through the use of ceiling fixtures, but also by windows, skylights, luminous panels, and plug-in lighting.

The members of the task group are:

The task group will seek input from design professionals, manufacturers, facility owners and scientists, review proposals being considered, vote on the technical merits of each recommendation and draft the recommended practice. The target date for publication of the recommended practice is May 2019.

“It is truly exciting to be part of this groundbreaking work on developing guidelines that can be used across the value chain, from designers and specifiers, to manufacturers and installers,” said task group member Govi Rao. “It will be a significant benefit to the user community to have a demystified and simple framework guiding the diverse approaches worldwide in the delivery of light, driven by rapid technological innovation.”

“Our goal is to investigate all aspects of the recommendations to ensure that the science is correct, to confirm that the methods of implementation can be accurately yet broadly applied, and to inspire a positive change in lighting practice,” said Dr. Rea. “Lighting isn’t just for vision anymore. It’s high time we had a valid, agreed-upon metric and some basic guidelines so that healthy lighting can be effectively delivered to benefit society.”
