Abstract: A system and method for cooling structures by pulling air underground through corrugated pipe is disclosed. The system allows the air to cool down prior to being pulled back into the structure. The system comprises: a trench located outside the structure; an elongated pipe resting in the trench, having a first end and a second end; a first manifold connected to the first end of the elongated pipe, and a second manifold connected to the second end of the elongated pipe; a first airtight duct connecting the first manifold to the structure, and a second airtight duct connecting the second manifold to the structure; a duct fan coupled to the second set of ducting such that the duct fan causes air to flow through the first airtight duct to the first manifold, then to the elongated pipe, then through the second manifold, then through the second airtight duct back into the structure, thereby cooling the structure due to a naturally cooler temperature of the elongated pipe located in the trench.
