<P>PROBLEM TO BE SOLVED: To provide an efficient ventilation and circulation structure of indoor air by a simple structure not depending on a mechanical ventilation device or a complicated heat exchange device by using natural air flows caused by temperature differences between a building interior and exterior, and plural ventilation air passages. <P>SOLUTION: The natural ventilation structure comprises at least two systems formed along structural material comprising a wall surface of the building, each of both ends of one air passage is opened to an internal space and the exterior, and each of both ends of another air passage is opened to the internal space and the exterior such that a vertical physical relationship is opposite to that of the one air passage. Natural ventilation and air circulation of internal space vertical layers are realized by using air flows in mutually opposite directions caused in the air passages by the temperature differences between the building interior and exterior, and between air of the air passages. <P>COPYRIGHT: (C)2008,JPO&INPIT |
