Ventilation and Radon Mitigation
My home is in climate zone 5a. We recently had a radon mitigation system installed due to elevated radon levels. It is a sub-slab depressurization system and is working very well.
However I have a couple of questions:
1) If I want to improve ventilation in the house (separate and apart from the radon issue), can I install an HRV or ERV or will this affect the effectiveness of the radon mitigation system? Said differently, what would be the best type of ventilation solution that would improve air quality and even help further reduce radon levels?
2) With this type of system installed, should I be wary about doing any air sealing or further insulation in the house? Will this cause radon levels to potentially rise?
3) Finally, and this is more out of general interest, is it possible to reduce the stack effect in a house (ours is 3 stories) in some simple, cost effective way?
