Smart building hybrid ventilation system under wireless sensor network environment

Abstract

Natural building ventilation is an effective method for maintaining comfortable and healthy indoor environments. This study aims to develop a novel smart building hybrid ventilation system capable of tracking wind direction using wireless control technologies and sensory capabilities. Natural and mechanical ventilation components are integrated to create a highly efficient and healthy ventilation system for a building. With this system, wind speed and direction are measured using a windmill anemometer, and this information is relayed to the control system. The control system uses this information to modify the openings of the adjustable rooftop developed in this study toward the direction of the wind using a set of interlinked devices. This guides fresh airflow indoors, improving the comfort of indoor environments through the circulation of airflow. This is expected to reduce the energy consumption of air-conditioning systems.
