Systems and methods for intelligent disinfection of susceptible environments based on occupant density

A building automation system may control ultraviolet lights to intelligently disinfect susceptible environments based on occupant density. The system comprises multiple occupancy sensors, a disinfection environment tracking engine, and an ultraviolet light control engine. The multiple occupancy sensors generate real time occupancy data associated with multiple objects detected within an area. The disinfection environment tracking engine determines real time occupant density of the multiple objects detected within the area based on the real time occupancy data generated by the multiple occupancy sensors. The ultraviolet light control engine controls operation of one or more ultraviolet lights to disinfect the area based on the real time occupant density determined by the disinfection environment tracking engine.
