A sensor-enabled rule engine for changing energy-wasting behaviours in public buildings

Activity of occupants in public buildings is a key source of energy wastage, yet hard to track and cope with. In this paper, we present a challenge-based logic in a gamified approach to alter energy-wasting behaviour. Each challenge is expressed as a rule, the accomplishment of which is verified on the basis of a sensor and energy metering infrastructure. We employ a challenge-focused cost-effective instrumentation approach regarding sensors and energy metering equipment installed in the buildings. A event-based processing approach validates user compliance to the various rules on an effective and scalable manner. Finally, we exemplify the operation of our system by walking-through the execution of a specific challenge.
