Vents are also important during the winter because it keeps moisture away. The benefits of vents during the winter are much better than the benefits it provides during the summer.
Best ventilation systems are those run with electricity – This may be partly true since exhaust fans effectively create a negative air pressure in the room, which allows cold air outside to be sucked inside. However, on larger scale, exhaust fans may not be as effective as it is. Mechanical ventilations are better because hot air rises and escapes through the vent. The continuous rotating motion of mechanical vents will continues to allow hot air to escape and cool air to come in. this is very effective for larger areas because it has higher amount of hot hair rising.
