This work studies about the application of passive design by a Trombe wall system to enhance indoor ventilation of Phnom Penh row houses. The system is designed to be installed next to a stair block wall on the top floor of a row house which faces south or west. The current work is investigating the effect of Trombe wall on ground floor facilities compare with the existing design without Trombe wall. CFD program is used as a processing tool. The results indicate that even the Trombe wall system is recommended to enhance indoor ventilation, the side of the system, the distance from the Trombe wall to a target room, the volume of a target room, and the ambient weather are relevant to achieved results. For all cases, the approximate air velocity got at the living room is in an average from 0.12 m/s to 0.16 m/s. At the same time, hot air is brought in by the blowing wind, results in the increase of room temperature around 2°C in the living room, and mostly no effect in a kitchen. Within these ranges of temperature and air velocity, the limited scale of the Trombe wall would not reach comfort standards.
