What is Attic Ventilation?
Technically, wind turbines aren’t a fixed vent system because they use a moving part to help exhaust air from an attic. That moving part consists of a series of specially shaped vanes that turn wind force into a rotary motion. As the spinning vanes gain velocity, they create an area of low air pressure. That low pressure, in turn, pulls air from an attic.
With all aluminum rust-free construction, wind turbines reduce energy bills. Permanently lubricated upper and lower ball bearings ensure that wind turbines offer long life and no maintenance.
The best place to install intake vents is in or near the roof eave or soffits. That location provides two key advantages:1. The soffit vents are better protected from rain and snow infiltration. Vents mounted in the eave provide almost total protection.2. Usually, when undereave vents are placed on both sides of a roof (as they should be), there’s always an equal distribution of high and low pressure areas.
Solar Attic Fans
Too Much of a Bad Thing!
Here is a great example of poor ventilation. There are two static vents on the top row with an old electric power fan that probably doesn’t work in the middle. In order to improve the situation somebody decided to install 3 fourteen-inch wind turbines BELOW the existing ventilation.
Unfortunately this will not help anything because the wind turbines are placed too low on the north side of the roof and will never spin with the predominately southern trade winds in the spring, summer and fall in Texas.
Even as passive ventilation they are too low on the roof, where heat will exit at the highest point. Too much ventilation this close together will also cause wind washing where each vent will try to pull air from adjacent vents, thus rendering them useless.
