Abstract: Disclosed are a system and method for developing computational models of the behavior of a building's occupants using data acquired from sensor-equipped connected luminaires. The models are then used to develop an optimized evacuation plan for safe and timely egress of the occupants without requiring mock evaluation drills.

Abstract: Techniques are described herein for workspace occupancy estimation using presence sensor data and a predictive model. In various embodiments, spatial distributions of workspaces (340) and presence sensors (342) may be identified (402) in an open environment and used to generate (406) a surrogate model. The surrogate model may indicate which workspaces in the open environment are within sensor range of each presence sensor in the open environment. A plurality of simulated occupancy patterns may be applied (408) across the surrogate model to generate a corresponding plurality of triggered sensor patterns. Based on the applying, a predictive model may be generated (410) for estimating occupancy among the plurality of workspaces in the open environment based on triggered sensor patterns. A real life triggered sensor pattern may then be applied (414) across the predictive model to estimate occupancy among the plurality of workspaces in the environment.

Abstract: A lighting plan generator configured to generate a lighting plan comprising a map of locations of a plurality of light units located in a space, the lighting plan generator being configured to generate the lighting plan from overlapping images captured by light units in a space. Orientation sensor information from each light unit is also received from each light unit to provide light unit orientation. The overlapping images are combined by aligning or rotating the images, using the orientation sensor information, to form a blended image and based on spatial information (e.g. distance between fixtures, camera field of view, and ceiling height). A lighting plan is then generated comprising a map of locations of a plurality of light units in the space.

Abstract: A method (300) to characterize one or more occupants within an environment (200) includes the steps of: obtaining (320), by a thermopile array (14) of each of a plurality of thermal sensors (12) of a sensor system (10), one or more thermal images from within the environment, wherein at least one of the thermal sensors is positioned along a first surface of the environment and at least one of the thermal sensors is positioned along a second surface of the environment; fusing (340), by the controller, a thermal image obtained by a thermal sensor positioned along the first surface with a thermal image obtained by a thermal sensor positioned along the second surface into a fused image; characterizing (360), from the fused image, a number of occupants in the environment; characterizing (360), from the fused image, a location of each of the occupants in the environment; and communicating (380) the characterized number of occupants and the characterized location of each of the occupants to an environmental control system (30).
