Passive Radon Mitigation using Solar/Wind Turbine Fan
Here’s my dilemma: New home less than 5 years old with passive radon mitigation system that runs up through the house exterior walls. Ceiling is vaulted so there is no attic or way to install a radon fan up there. Got quote to reduce radon and contractor said to cap off the existing pipe and install a new pipe that runs up along the outside wall with an attached fan, essentially abandoning the existing passive system.
So I’m wondering if anyone encountered this scenario: there are solar/wind powered turbine fans that are installed on the roof to remove heat from the attic. Since the passive radon system works by wind passing across the top of the pipe and drawing out the radon, it would seem that these attic turbine fans could possibly enhance that process significantly without incurring the electric costs in running a 24/7 radon fan. It would be about one third the cost of a replacement system and more green and more attractive; at least it would seem. Thoughts?
