Hybrid ventilation system is a two‐mode system that can automatically switch between passive and mechanical modes at different times of the day or season of the year. In this study various ventilation systems, including hybrid system, are used for the investigation. These systems are set up in a full‐scale test house constructed in the Tohoku University, Japan. Case studies for evaluating the performance of these systems, by field studies and numerical simulations, are described. The results obtained from this study show that, the hybrid system can supplement the under‐ventilation even under a milder weather condition and the airflow rate can be fixed at a certain high level, in comparison with passive system.
