A system of mechanically moving cool air into the hot attic space within a building structure such as a residence, which reduces the heat load on the habitable portion of the building structure, and thus allowing efficient cooling. The cool air is drawn from a vented crawl space, from a cellar or a basement space through applicable ducts, and a vertical duct or air chase upward into the attic using a controlled fan/blower air handling apparatus. The cool air then flows into the attic through applicable ducts and forces the attic air outside through exterior attic vents. In this system the possible irritants and contaminated crawl space air, basement air, or attic air is not vented into the habitable living space of the building, thus providing a healthier living environment for the inhabitants. This system can be adapted to applicable existing and new building structures of one or multiple floors.

1. A cool air ventilation system of reducing the heat load on a building structure, said building having:an enclosed walled crawl space, with an earth base, covered with a flexible plastic membrane or concrete covered floor surface below the lowest elevated indoor habitable floor space;an attic space between the upper roof structure components and the ceiling structure components located above the ceiling in the upper most habitable indoor living space;a closed off habitable indoor living space of single or multiple floors located between the lower crawl space and the upper attic space;a controlled air handling apparatus mounted within the building structure, said air handling apparatus comprising:a. external housing,b. a service door located on the exterior of the external housing,c. an electric powered motor driven fan/blower within the air handling apparatus,d. an air filter housing for an air filter within the air handling apparatus,e. a backflow damper attached to the air handling apparatus,f. a plurality of control means to create efficient operation of the air handling apparatus,g. and a means of attaching ducts for the supply air and ducts for the discharge air to the external housing of the air handling apparatus;the same air handling apparatus with attached ducts for moving the cool air from the crawl space to the attic space;an applicable duct system means with openings for capturing cool air from the vented crawl space;an applicable vertical duct/air chase means for moving air from the crawl space to the attic space;a plurality of vent opening means in the crawl space exterior walls permitting outside fresh air to be drawn into the crawl space;and with a plurality of vent opening means in the exterior elements of the attic building structure attic space which allows air to exit the exterior of the building structure. 2. The building structure of claim 1, and further comprising;a cellar/basement space for drawing cool air,a. said air supplied from applicable openings in the cellar/basement walls,b. and said lower cellar/basement earth base covered with a flexible plastic membrane/concrete floor. 3. The controlled air handling apparatus of claim 1 fabricated with:a. an external four sided frame housing without door,b. and a flange for connecting to a vertical air chase/plenum. 4. The cool air ventilation system of claim 1, comprising;of an independent air conditioning system for additional cooling of the habitable indoor living space.
