Heating of the windtower itself can heat the air inside (making it a solar chimney), so that it rises and pulls air out of the top of the house, creating a draft. This effect can be enhanced with a heat source at the bottom of the windtower ( such as humans, ~80 Watts each [ citation needed ] ), but this heats the house and makes it less ...
Cross-breezes work when two windows are opposite of each other. Cross ventilation is a natural phenomenon where wind, fresh air or a breeze enters upon an opening, such as a window, and flows directly through the space and exits through an opening on the opposite side of the building (where the air pressure is lower).
The draft (draught in British English) flow rate induced by the stack effect can be calculated with the equation presented below. [ 12 ] [ 13 ] The equation applies only to buildings where air is both inside and outside the buildings.

The fan works by drawing air in through an inlet in the base pillar and forcing it through an outlet in the upper ring. The jet of air travels over the airfoil shape of the ring, creating local low pressure, thereby pulling air from behind it as it decelerates in a process known as "induction". [40]
