A number of studies have examined the potential of using natural ventilation as a passive cooling system and comfort under warm conditions. Tanabe and Karma (1994) conducted an experimental work at 50% RH under different level of air speed. They found preferred speed at 28oC to be 1.0 m/s, at 29.6 oC, 1.2 m/s and at 31.3oC, 1.6 m/s. Although traditional architecture of Iran has a very good back...
