Abstract
There has been considerable debate in the residential sector regarding whether it is better to provide exhaust-only ventilation - which removes contaminants but bring air in from uncertain locations - or supply-only ventilation - which ensures that the provided air comes from outdoors but which may mix contaminants in the home before they leave. This project compared these two ventilation strategies in 18 homes in Central Illinois. Measured contaminants included carbon dioxide, radon, PM2.5, formaldehyde, and moisture. The results showed that, within this sample of homes, both strategies tended to reduce these contaminants with exhaust-only suggestive of providing slightly better benefits.
