A controlled field test of radon reduction through solar ventilation at six homes in Northeast Iowa
- Univ. of Northern Iowa, Cedar Falls, IA (United States)
This study evaluates an original radon mitigation technique which uses solar-heated ventilation air to reduce radon and other indoor air pollutants. Providing energy-efficient make-up air for combustion appliances and stack effect losses, the Solar Radon Reduction System (SRRS) improves indoor air quality through dilution, slight pressurization, and reduced radon infiltration. Solar heating of intake air produces net energy gain in cold seasons, and the SRRS blower provides summertime cooling during low outdoor temperatures. Research methodology includes synchronized hourly radon data collected at five test homes and a {open_quotes}control{close_quotes} maintained under closed conditions over five 10-day test periods. The control closely correlated weather-related radon trends, particularly with leaky homes, and thus serves as an appropriate reference for simultaneous multi-home remediation measurement. Installed at six homes in northeast Iowa, the SRRS was found to significantly reduce winter-time radon at all homes with elevated levels by an average of 49%.
