The Relative Value Of Weatherization: Comparing Energy Savings, Monetized Health Impacts From Changes In Indoor Air Quality, And Home Improvement Costs

Historically, the benefit of weatherizing homes has focused on decreasing energy costs to homeowners, with little quantitative evaluation of other effects—in particular, indoor air quality (IAQ) and subsequent health effects. The purpose of this study was to examine the relative impact of weatherization on energy savings and potential health implications from changes in IAQ. Using data from a cohort (n=49) of homes undergoing weatherization across the three distinct climate zones in North Carolina, this study performed an analysis that included building characteristics, weatherization improvements, and costs, along with indoor air quality data.
