BUILDING CIRCULATION SYSTEM

摘要

A building ventilation system is provided to carry out ventilation of a building naturally by introducing atmospheric air via a space between the outer wall and the exterior wall of the building and discharging polluted room air via a vertical path connected with exhaust ducts. A building ventilation system includes a vertical path(100) separated from room spaces(44) of each story by a vertical barrier wall and extended from the basement space to the roof area of a building vertically and communicating with atmospheric air, and exhaust ducts(300) connected to each of the room spaces and the vertical path. An exterior wall(200) is mounted apart from an outer wall(22) formed with windows(33) of the building and surrounds the exterior of the building. The exterior wall is formed with an atmospheric air inlet(220) at the lower part, and a second air outlet(210) serving as a path for discharging the atmospheric air remaining after being introduced into the room spaces, to the outside.
