Abstract
A method for utilizing an automated lighting system having a plurality of lighting fixtures with associated light sensors to determine occupancy of a plurality of occupants in an area of a building. Lighting level information is received from the lighting fixture sensors of the automated lighting system identifying lighting variations in an area to form a time-based history of lighting level variations. Analytic analysis is applied to the time-based history of lighting level variations to determine a time-based occupancy in the area.
