Title
A wi-fi based occupancy sensing approach to smart energy in commercial office buildings.
Abstract
Buildings account for a considerable part of energy consumption. Prior research has shown that much energy could be saved by using occupancy based building automation techniques. One of the remaining challenges is how to collect real-time occupancy information that is practically accurate yet without incurring high deployment costs. We will demonstrate a prototype system that is being experimented in a typical IT office building. Our system derives coarse-grained occupancy information by sniffing wi-fi signals and fine-grained information by wi-fi based indoor positioning. The synthesized information provides sufficient accuracy for zone-based HVAC and lighting control. Due to wide-spread usage of wireless APs and mobile devices in IT buildings today, the deployment cost of our system is low.
