In this study, the characteristics of wind induced ventilation with single-sided opening are analyzed with wind tunnel experiment. In some experimental cases, a small wind break is attached on an opening in order to increase amount of air flow rate. (It is assumed that the break is an opened window itself so that the window is pivoted one whose vertical axis is placed at center of window.) The normalized airflow rate 'k' in the case of a standard single-sided opening is 0.024. On the other hand, 'k' in the case where a small wind break is attached vertically to the opening is 0.156. This value is about 6.5 times as much as 'k' in the case of a standard single-sided opening. In other experimental cases, circulation flow is made in a room in order to increase air flow rate. Synergy effect of fresh air entering from an opening and circulation flow is expected. The normalized airflow rate 'k' in the case of a standard single-sided opening with circulation is able to increase more than 'k' without circulation. In some cases however, 'k' with circulation is reduced due to shortcut.
