We consider a wireless networked, sensor-driven lighting system as an enabling infrastructure for providing system solutions and services in intelligent buildings. The lighting system in an office space consists of multiple luminaires, with each luminaire having a co-located presence sensor, light sensor, and wireless radio for communication to a central controller. Information from these wireless sensors is used for realizing three specific solutions and services: 1) adaptive illumination control; 2) indoor positioning; and 3) building usage information maps. Using occupancy and light measurements from the multiple sensors, a multivariable controller is designed to determine dimming levels of the luminaires so as to achieve an illumination distribution adapted to changing occupancy and daylight. The wireless sensor transmissions to the central controller are captured by a user mobile device in terms of radio signal strength measurements. Using these measurements, the user position is determined by a device-centric positioning algorithm, in turn offering access to location-based building services to the user. Finally, sensor values at the central controller are stored in a database and processed by an analytics engine to offer building usage information services. As an embodiment service, we use presence sensor data for constructing occupancy maps and, in conjunction with light sensor data, to analyze the energy consumption patterns of lighting systems.
