Energy studies show that if the home has a properly insulated attic the
installation of a power vent will not decrease air conditioning energy
cost enough to pay for the operation of the power vent fan.
That is true in new construction where the attic is properly ventilated
by continuous ridge and soffit vents. It is NOT the case on many
buildings of older design.
We've done some solar-powered vent in INDIANA that seem to work well,
provided that attic is also properly insulated and leaks between the
conditioned spaces and the attic are minimized.
