The turbine ventilator on top of this cupola uses natural wind power to pull warm air up and out of the building.
This cupola allows warm air to escape and draws cool air in through lower windows.
A house with low and high air outlets achieves the best air flow.
The chimney effect pulls warm air up and out of the home as it pulls cooler air inside. South-facing glass on the chimney increases the difference in air temperature from top to bottom and enhances airflow.
Landscaping, such as trees and shrubs, can help funnel precooled air into open windows.
Wind catchers, such as this four-sided model, capture cooler air from above the roofline and scoop the breeze down into the home.
