An air circulation system for a building or other enclosed space that includes an heating, venting and air conditioning (HVAC) unit and a first air duct connecting the HVAC unit with the interior of the building. The system also includes a second air duct connecting the exterior of the building with its interior. A fan or secondary unit directs and moves air from outside of the building to inside the building when a controller determines via one or more sensors that an outside condition is preferable to a condition inside the building. The system also may be used in vehicles such as in ground-based vehicles including public transports, and in aircraft.
