Interesting!

The Venturi effect, which is an example of the Bernoulli effect, has a tremendous effect on the design and ventilation of buildings. If you have ever felt the gust between tall buildings, you have experienced this effect.

Done right, a structural engineer can place windows, doors, and trees to maximize air flow and minimize the need for HVAC systems. Done wrong, the pressure differential can cause windows pop out of glass skyscrapers.

It is amazing to me that Native Americans, Moroccans, and other groups figured out that building high ceilings, placing windows in just the right spot, and planting trees in specific locations and distances from a house promoted breezes into and out of their abodes - long before fluid mechanics were known.

This is why hiring structural engineers are worth their fees ten times over in building design.
