ABSTRACT:
A system and method of vent placement within a building is provided for improved passive ventilation. Vents are provided within the dividing structures or material layers that form the building's exterior and interior walls, ceiling, roof, floor, and/or intermediate story-defining “ceiling-floors.” Preferably, each vent is not a conventional ventilation stack and is oriented generally along a planar portion of the dividing structure within which the vent is positioned. Preferably, each vent is substantially entirely contained within its associated dividing structure. Vents are provided in corner sections of exterior walls, roof-portions, and the bottom floor of the building. Vents are also provided in corner sections of the ceiling portions, floor portions, and wall portions that define the interior rooms of the building. The vents are preferably vertically aligned throughout a substantial portion of the height (or more preferably substantially the entire height) of the building, at one or more horizontal positions thereof, to thereby produce one or more substantially vertical flows of air upward and out of the building, without the use of stack vents.
