Abstract

Formaldehyde concentrations in newer, energy-efficient homes are modeled for a typical new home using median data gleaned from government databases and surveys on home construction. Studies show that such homes have reduced infiltration rates and are constructed using some materials that release formaldehyde. Emissions rates of these materials are estimated from existing studies, and concentrations calculated based on a steady-state model. The resulting projections of formaldehyde concentrations are compared to OSHA and NIOSH workplace standards. Mitigation efforts are recommended to reduce the potential for high concentrations of formaldehyde in the home.
