The goals of the system are (1) Improve Indoor Air Quality by Ensuring Conditioned Filtered Outdoor Air Is Supplied for to the Structure for Improved Respiration and Controlled Room Temperature and Humidity, (2) Minimize Moisture, Contamination, and Deterioration of the Building Envelope by Allowing Air Exhausted from the Interior to Flow Through the Building Envelope, and (3) Reduce Energy Costs by Allowing the Air Flow Through the Building Envelope to Minimize Thermal and Moisture Flow Between the Exterior and Interior
