A Wind-Driven Ventilating Structure For Inducing Wind-Driven Ventilation In Buildings
A wind-driven ventilating structure for inducing wind-driven ventilation in a building is disclosed, in accordance with an embodiment of a present invention. The structure includes at least two airfoils- a first and a second, placed in parallel with one another, having at least one more airfoil- a middle airfoil placed in between the two airfoils. The middle airfoil has curvature two times higher than that of the first and second airfoils for increasing speed of circulating wind inside the building such that air change per hour (ACH) attained is 34 per hour.
