This article from Air Quality Sciences explains the benefits of public and private schools that combine energy conservation with improved indoor air quality. A major concern is the increased initial cost to build a green school, even though the operating costs over a 40-year (or more) lifetime are expected to be lower for a green building than traditional construction that meets building codes. Good indoor air quality is claimed to improve student attendance and performance. The chemical constituents of indoor air are presented. Among the pollutants are volatile organic compounds, mold, and formaldehyde. The impact on asthma and autism is discussed.
