With a home that is super-insulated, there are always concerns about air quality. A home that is well sealed against air infiltration may have moisture buildup, as well as the build up of pollutants from cooking, cleaning and offgassing from building materials, finishes and personal possessions in a home. In winter, closed windows and central heating may cause very dry air. And the very act of living in a home means we exhale carbon dioxide that needs to be replaced with fresh air.

In the past, most of these problems were solved by very loose construction that allowed lots of air to infiltrate a home, through the walls, windows, doors, floors, etc.
