A method and apparatus for venting heated air from the upper portions of a room in a dwelling or the like, the invention acts to reduce heat loading within a building by providing a siphon vent pipe which opens into the upper portion of the room and extends upwardly into communication with a draft channel disposed near the roof of the building. Heated air within the upper portions of the room is thereby first vented from the room and then subsequently vented externally of the building through a vent formed in the roof of the building.
