A Wireless Sensor Network for energy efficiency in an educational environment

Following design and implementation of a Wireless Sensor Network (WSN) in an educational environment, measurements on the electricity consumption are collected and analyzed. This WSN is developed as part of the EnPROVE project (www.enprove.eu). The WSN is used to measure multiple parameters in a university building. The building is divided into various zones. Each zone represents an area with uniform specification. The measured parameters include lighting and HVAC (Heating, Ventilation, and Air Conditioning) data. In particular data about presence (representing occupancy), temperature, light level, light actuation and windows open/close status are collected. Light, temperature and occupancy measurements in conjunction with electricity consumption are the subject of analysis in this paper. Further analysis is conducted on the impact of changing the timeout of the automated light actuation on the electricity consumption.
