Abstract

We set out to study the ways that weatherization alters indoor air quality, including the composition and structure of indoor microbial communities. We sampled microorganisms, a wide range of air quality metrics, and administered an extensive health and behavior survey in 66 homes across Portland, OR. While we observed no gross effect of weatherization treatment, we found that the community dissimilarity between paired indoor/outdoor bioaerosol samples is related to seasonal patterns of window operation, and that the synchrony between indoor/outdoor air quality measures helps explain the dissimilarity in microbial communities. This helps us understand the relationship between home operation and shifts in microbial community dynamics that may affect the health of building occupants.
