Prevailing breezes above roof level are frequently as much as 15-20 degrees
cooler than ground level air. In Pakistan for the past 3,000 years people
have
put tall vents atop their homes, with the openings angled toward the
prevailing winds. That way when it gets to be 120 degrees outside, a cooling
100 degree
breeze can circulate down the shaft and into the home.
