This work presents the use of the Internet of Things (IoT) concept as a tool for developing a wireless network of sensors and actuators to propose a technological update in air conditioning units installed in Saudi educational, industrial, and residential buildings. One way to improve modern buildings' energy efficiency is to apply control and decision mechanisms to decrease power consumption. To achieve this goal, data are collected over several months using a Wireless Sensor and Actuator Network (WSAN). Gathered data then applied to an Energy Efficiency Management System (EEMS) to find suitable solutions to have a maximum energy efficiency ratio. The WSAN hardware system is installed in the Engineering Building of Suhag University. The WSAN is linked to the EEMS software for monitoring and recording data received from sensors. The collected data are analyzed, and energy efficiency solutions are applied. Results were promised, and the efficiency ratio reached 23%.
Key words: Real Monitoring, Energy Efficiency Management System, WSAN, Suhag University
