Mechanical ventilation is often furnished by machines that is also used to heat and cool an area.
Having said that, natural ventilation can be significantly less successful in selected situations, such as when there is little if any wind, or when the skin air is polluted or normally undesirable. It may also be much less controllable than mechanical ventilation, as it depends on exterior variables which could differ with time.
