Abstract
Daylight is essential to human productivity. It has been shown that if we do not receive
enough daylight, our health and well-being is negatively affected. However, an overabundance of daylight
into the indoors can make performing with computer-based visual tasks difficult and uncomfortable due to
glare. This study is a collaboration with SRG Partnership, an Architecture firm in Portland, OR, to analyze
their own workspace in determining optimal amounts of daylight as an occupant-centric circadian resource
in the office. The historic office space has large south-east-facing windows that can be a source of glare,
which negatively affects productivity, and are controlled manually with motorized shades. Participating
occupants were given a wearable light sensor to track the light levels received throughout the day over the
course of one work week. Sunshade use was also monitored and recorded.
