Short Paper:: The Smart Conference Room: An Integrated System Testbed for Efficient, Occupancy-Aware Lighting Control

A key challenge to lighting testbed development is the design of system architecture, both in terms of hardware and software, that supports the exploration of transformative systems concepts. Here, we introduce the Smart Conference Room (SCR) at the NSF Engineering Research Center for Smart Lighting. This regularly-used room combines multi-channel solid state light sources, advanced sensors, and sophisticated control algorithms to provide efficient and comfortable lighting where and when it is needed. We specifically discuss two interrelated sensing and control systems in the SCR. The first uses a sparse network of single-pixel color sensors for closed-loop feedback control of the light field in the room, driving the light field to a desired setpoint while harvesting incoming daylight and balancing energy costs. The second uses a low-resolution array of time-of-flight sensors to track occupants, identify their behavior, and trigger lighting modes, all while preserving their privacy. We describe ongoing and future experiments in the SCR that drive the specifications and development of new sensors, sources, and advanced control algorithms.
