Microbial contamination of indoor air due to leakages from crawl space – a field study
Mechanical exhaust ventilation systems are typical in apartment buildings. In most buildings the base floor between the first floor apartments and crawl space is not air tight. As the apartments have lower pressure than the crawl space due to ventilation, contaminated air may flow from the crawl space to the apartments. Download the Field Study →
