Abstract

Wind catchers/towers systems were employed in buildings in the Middle East for many centuries and they are known by different names in different parts of the region.They were constructed, traditionally, from wood-reinforced masonry with openings at the height of 2 to 20m above the building roof. Taller towers capture winds at higher speeds and with less dust. Their application in the hot arid region of the Middle East is to provide natural ventilation/passive cooling and hence thermal comfort, exploiting, particularly, night-time ventilation strategy. They can be beautiful objects, feasible architectural features and are inherently durable. This paper provides a categorization of wind-catchers in Yazd based on their attributes and parameters and stipulates on the best wind catcher plan geometry and height for reducing the indoor temperature experiment are conducted using 3-D computational fluid dynamics (CFD) simulations to compare indoor air temperature in different square wind catchers with different height.
