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;
exhausting at least one of vapor, gases and said fresh air collected in said channel, said at least one exterior wall, and said lower portion of said structure through said exhaust fan to the exterior of said structure.

Abstract
A dual ventilation system is provided for a structure. The system has a suction tube assembly with an exhaust outlet in an upper end thereof and an exhaust fan therein. An intake vent or other intake means is in a lower portion of the structure in flow communication with the suction tube assembly. At least one channel is proximate a lower portion of the structure in flow communication with at least one lower interior portion of an exterior wall of the structure and in flow communication with the suction tube. In structures having a sump pump, the sump pump liner is in flow communication with the channel.
