Anotations

Scope note:

Wind catchers consisting of a tall tower, generally square in plan with X-shaped panels set diagonally across the interior from corner to corner, open at the sides near the top to funnel and accelerate incoming breezes down one channel to cool spaces below creating by convection an updraft in the opposite channel which draws warm indoor air out; Persian in origin, found in Iran and the Gulf countries.
