Whirlybirds are cylindrical domes that sit on the roof of a building and spin in the wind, creating a vacuum which extracts warm air from the ceiling cavity. When the sun beats down on the roof, it heats the ceiling and roof cavity up to excessive temperatures. As a result, the heat infiltrates the interiors, making the living spaces uncomfortable and stuffy. To compensate for this compensated heat, whirlybirds offer an electricity-free roof ventilator to manage roof space temperatures.
