solar chimney geometry

Natural ventilation is a well known strategy to improve indoor air velocity and reduce indoor temperature. It is the main criterion to achieve thermal comfort in terraced housing in Malaysia. In hot and humid climates, one drawback to single sided ventilation is that the wind effect is not well captured, which in turn, increases the use of mechanical cooling. Therefore, it is important to understand and consider the use of the solar chimney as a stack induced ventilation strategy for a single sided ventilated room.
