EPA has developed guidance for maintaining or improving indoor air quality in homes, schools and businesses.

Extreme weather conditions associated with climate change, such as more frequent and intense storm events, may lead to breakdowns in the physical barriers between outdoor and indoor spaces of homes and buildings. The deterioration of barriers may allow water and moisture to permeate. Damp conditions are ideal for the growth of indoor fungi and mold, increasing the likelihood of occupants’ exposure and resulting health effects.
