Natural Cross ventilation
Cross ventilation is a condition where the windows on the opposites of the house are open. It means that high and low pressure zones which is created by the wind and breezes for providing the fresh air is used. If the natural cross ventilation is used, the placement of the opening such as doors and windows and the patterns of the flowing patterns should be paid attention.
