The basic concept of a hybrid ventilation system is to provide an acceptable indoor air quality by alternationg the passive ventilation mode and the mechanical ventilation mode for minimizing the energy consumption. Therefore, the control strategy for the supplemental fan and the damper of hybrid ventilation system is very important for the system performance. The hybrid ventilation system using a pressure difference sensor for monitoring the exhaust airflow rate as the control strategy was installed in a detached test house. Performance of this ventilation system was evaluated through the field measurement. The results of the measurements showed that the exhaust airflow rate was relatively stable while the indoor-outdoor temperature difference varied and the wind velocity changed. But when the wind velocity was strong from the west, the airflow rate was far from the target airflow rate. Totally, the airflow rate met almost the target airflow rate in 75% of the measuring period.
