Air flow around house
Image information
Description
This drawing illustrates the actual wind flow around a simple gabled house, although simplified and in only one direction.
As air pushes against the windward side of the house, it creates positive pressure and pushes air up and into the soffit vents. Pressurizing the attic.
As air flows around the house it compresses and increases velocity. This creates the low pressure that pulls air from the attic openings, whether ridge, static, or gable end, in the roof or walls.
In actual real world conditions, the wind will come from different directions, and affect the attic vents in different ways. Either pushing or pulling air out of the attic space.
