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.
