All About Natural Ventilation

What Does Natural Ventilation Mean To You?

The process of drawing fresh air from outside into a building. This fresh air then helps to force the hot, dirty air from the inside out of the building through the roof opening. This is done without the need for mechanical assistance.

Although this is the concise definition of it, its actual application and use are much more complicated. You can find the best ("In English natural ventilation in buildings") ventilacin natural en edificios services via www.syp-urban.com/servicios/ventilacion-natural.

Two types of ventilation can be found naturally in buildings. You can choose from wind-based ventilation, also known as cross-ventilation, or Buoyancy driven ventilation, also known as stack effect ventilation.

Wind-Based Ventilation

The pressure created by wind blowing past buildings will vary. The area with high pressure is the windward side, while the roof and leeward sides are low pressure. By strategically placing different types and sizes of openings in high- and low-pressure areas, air can flow more quickly and in the desired direction.

An open window is the best way to see wind-driven or wind-based ventilation. The fresh air enters through one side and moves through the building. It then exits through the other side pushing out the warm, stagnant air.

Buoyancy Driven Ventilation

It looks complicated but works just like a fireplace. This process causes warm air to rise because warm air rises while cool air remains low.

The ceiling is where heat rises from within buildings. Large buildings with a high structure will have a natural tendency for warm air to rise. This causes air movement throughout the building.
