VENTILATION TECHNIQUES

RADON SHORT ARTICLES: VENTILATION TECHNIQUES

Have you ever wanted to use ventilation to reduce the radon concentration?

Here are some common techniques:

Heat Recovery Ventilation (HRV)
Interior air is exchanged with fresh outdoor air as a means to dilute radon and also recover the heat of exhausted air.

Crawl Space Depressurization (CSD)
Air exhausted from crawl space before radon in crawl space can enter the living space above.

Basement Pressurization
Air from the upper floor blown into the basement to pressurize it and prevent the entry of soil gases.

Building Pressurization
Where additional outdoor air is provided through an HVAC system where it can be conditioned before entering the building. Pressurizes interior and resists the entry of soil gases.
