The Radiance lighting analysis and visualization software was used to analyze the correlation between daylight sensing photocells and available illuminance from daylight in a small private office with vertical glazing and dimmed electric lighting. A variety of photocell configurations were considered, including unshielded, partially shielded, and fully shielded photocells which were mounted in a variety of positions on the ceiling and walls of a room. Different window orientations and daylight conditions were also considered. The study was performed with direct, indirect, and direct-indirect electric lighting systems. The results provide valuable information regarding photocell configurations and mounting locations and their relation to system performance in tracking interior daylight levels for the lighting conditions tested.
