What is natural ventilation? It's utilizing wind with the "chimney effect" to draw warm air out of the home and replacing it with cooler air from outside. As the wind blows against your home, it forces air into open windows on one side of the house while a vacuum effect draws the air out of the windows on the other side. The vacuum effect relies on convection. As cool fresh air is pulled into the home it absorbs heat from the room, the warm air rises and exits through rooftop vents or skylights on the upper floors. As the warm air moves out of the space, cooler fresh air is pulled in behind it. When mechanized to operate by a thermostat, natural ventilation systems modulate the temperature in your home efficiently. Countless benefits come with natural ventilation. Here are a few:
Low utility bills
One of the primary advantages of using a natural ventilation system is the decrease in your energy bills. Natural ventilation and hybrid ventilation consume much less energy (or no energy at all) compare to these mechanical systems. To save more on energy consumption, perhaps going for a natural hybrid ventilation system that cuts down on your energy use would be best.
Natural ventilation systems have a low energy consumption level. This makes them the best choice when looking to increase efficiency in a building or home. You can save up to 70 percent of your emissions, much more than the traditional mechanical ventilation.
The overall cost of maintaining HVAC ventilation is high, compared to natural ventilation systems. Natural systems generally come with fewer, more affordable parts.
A natural ventilation system takes very little space, especially as compared to an automated system. If you don’t want bulky components, a natural system is the better option.
Natural ventilation systems work best in areas where the days are warm and the nights are cool. If you live in an area that is very humid or where day and night temperatures are similar, natural ventilation systems are less effective.
