We propose a system that can accurately determine the occupancy of zones within a building. As an easily deployable sensor system, TOSS provides detailed information about a zone's occupancy to a building's energy management system in order to control the Heating, Ventilation, Air Conditioning, (HVAC) and lighting behavior for specific zones within the(More)
Buildings are often inefficiently conditioned. Rooms that are empty are needlessly conditioned and partially filled rooms are conditioned assuming maximum occupancy. In this demonstration, we describe a system that reduces energy consumption by opportunistically reducing energy consumption based on room usage; we only condition rooms currently occupied and(More)
Humans spend 90% of their lives inside buildings, but often the Heating, Ventilation, and Air Conditioning (HVAC) systems of commercial buildings do not properly maintain occupant comfort. Use of feedback through comfort voting applications has been shown to improve the quality of service, but the effects of application feedback and user interface design(More)
We present a holistic architecture for energy management in sensor networks. Our architecture is based on a model-driven approach which attempts to (a) establish functional relationships across different components of the software stack and the interrelated parameters based on empirical data, (b) use the maximum sensor value and time-synchronization errors(More)
