Openable windows of multiple dwelling houses or office buildings are often put on the single-sided wall because of restriction due to architectural planning. Conventional prediction method of airflow rate based on the differential pressure coefficient works on the assumption that openable windows exist on the both, windward and leeward sides of the room. This method is not useful for the room with single-sided opening. The prediction method of air flow rate of single-sided room beneficial to design process is not sufficiently prepared. In this study, the characteristics of wind induced ventilation with single-sided opening are analyzed with wind tunnel experiment, in which wind velocity profile of the approach flow is created as well as wind velocity profile around a building in build-up area. The normalized airflow rate 'k' is obtained from the wind tunnel experiment for simple prediction of airflow rate of single-sided room. The simple prediction method is mainly based on the normalized airflow rate 'k' and assumed wind velocity around a building, which is decided by CFD simulation or measurement.
