PNNL collaborated with ETC Inc. to capture light exposure variation at factory, manufacturing, and office employee workstations at ETC’s Headquarters in Middleton, WI. Employee surveys requested data on daylight exposure, motivation, alertness, and lighting satisfaction. This session examines the lighting measurements and survey data to highlight the complexity of lighting for healthy workplaces. The magnitude and duration of light exposure in relation to occupant outcomes will be discussed in the context of current light and health research and recommendations such as WELL. This session is for anyone interested in learning more about the variability of the human experience in buildings.
- Participants will be able to create a plan for characterizing light exposure at the eye of the occupants.
- Participants will be able to recognize the variation in vertical light levels between seasons and work locations and apply findings to design work.
- Participants will be able to describe the relationship between the measured lighting conditions and occupant outcomes reported via daily surveys.
- After this session, participants will be able to utilize the new tools and research methods presented to conduct future research regarding light and health in buildings.
