Can SolarVenti produce cool air for ventilation?
Yes, it is easy to extend the system so that it blows cool air into the building. This requires an extra fan on the north side of the building and a room thermostat which switches between the fans. You can increase the cooling effect of the extra fan on the north side of the building by drawing the air through a cooling pipe (which is buried in the ground) before it is injected into the building.
