5. WIND TOWER EARTH COOLING AT A DEPTH OF ABOUT 4 M BELOW GROUND TEMPERETURE INSIDE THE EARTH REMAINS NEARLY CONSTANT ROUND THE YEAR AND IS NEARLY AND EAQUAL TO ANNUAL AVERAGE TEMPERATURE OF THE PLACE. EMBEDDED AT A DEPTH OF ABOUT 4M BELOW THE GROUND WILL ACQUIRE THE SAME TEMPERATURE AS THE SURROUNDING EARTH AT ITS SURFACE. The function of a wind tower is to catch cooler breeze that prevail at a higher level above the ground and to direct it into the interior of the buildings. REAL LIFE EXAMPLES: PAGE5
