Ventilation strategies for radon reduction are employed for a variety of reasons, typically when a traditional ASD or SMD system is not practical. But selling a ventilation job without being able to predict the expected radon reductions is tricky.  What happens if the radon levels don’t change as expected?  Are there comfort or energy considerations if the ventilation guidance of ANSI/ASHRAE Standard 62.2 is exceeded?  Various methods of estimating the potential impact of increasing ventilation will be demonstrated.  This will give you the confidence to recommend a ventilation strategy when appropriate while providing the customer with meaningful estimates of the expected radon reduction.
