In this work a solar chimney with the aid of a humidifier located in opposite wall is applied as a passive solar technique for cooling building in arid regions. A test room was made from wood material except for the south wall, Trombe Wall; it is composed of a commercial glass wall apart from masonry thick wall with 10 cm gap. The experiments were carried out on summer in the arid region along the day hours with and without humidification process. The experimental observations show a reduction in room temperature, reaches to 8oC. The experimental results show an increase in natural air ventilation, with air velocity reaches to 1.6 m/s. Therefore, human thermally comfortable indoor environment for many hours during hot summers is achieved. The present study shows a Trombe wall with a movable air gap is recommended for the human comfortable along the day hours.
