Abstract:
1. A method for ventilating a building structure comprising the steps of: creating a negative pressure within a channel, said channel being proximate an interior side of a footer of at least one exterior wall of said structure and having a plurality of apertures therein to depressurize an area beneath said structure; creating a negative pressure within an interior of at least one exterior wall of said structure; creating a negative pressure within an interior lower portion of said structure, said interior lower portion defined by one of a basement, a crawlspace and a lower floor, said interior lower portion being located within a perimeter defined by said at least one exterior wall and above a lower substrate of said building structure, said lower substrate defined by one of a concrete slab or a crawlspace vapor barrier; providing substantially unobstructed airflow communication from said interior lower portion toward an exhaust fan through an air intake vent and an air intake vent pipe, said air intake vent pipe extending between said air intake vent and a suction tube in further flow communication with said exhaust fan for said creating said negative pressure wherein fresh air from said interior lower portion is pulled from said interior lower portion downwardly through said lower substrate through said air intake vent pipe and to said suction tube toward said exhaust fan;
