A simple question: If you place the air intake of the ventilation system on the opposite side of the property and lay underground pipes up to the house, about 50m (164 feet) long, does that really make a difference in terms of temperature? Theoretically, the air should cool down in the ground so that hot outside air is not blown directly through the house in summer. But does this really work, or does the air flow through so quickly that it has no effect?
