Abstract
A building system includes a communication network, a plurality of wireless nodes, a plurality of passive wireless devices, a plurality of sensors, and a processing circuit. The wireless nodes are disposed within a building and are operably coupled to the communication network. Each passive wireless device is affixed to an object within the building, and contains first information regarding at least one property of the object. Each the passive wireless device is configured to communicate wirelessly to the wireless nodes using power derived from communication signals detected in the passive wireless device. The sensors are configured to generate second information representative of sensed temperature throughout the building, each sensor operably connected to the communication network. The processing circuit is operably coupled to receive the first information from the wireless devices and the second information from the sensors. The processing circuit is configured to generate control information regarding the building based on the first information and the second information.
