Indoor Environment Quality

Materials and VOCs

Many products can contribute to indoor air pollution, such as school furniture, carpets, adhesives, paint, finishes and cleaning products. Products such as these often contain formaldehyde and other chemicals that can be hazardous to the health of building occupants. When these products off-gas, they may cause dizziness or induce asthma attacks. Children are especially susceptible because they respire more in proportion to their body weight. By using low emitting materials rather than common indoor building materials, schools can eliminate many sources of pollution before they even reach the building site.

Water-based paints are lower in VOC content than solvent-based paints.'

Volatile organic compounds contribute to indoor air pollution. Eye and respiratory tract irritation, headaches, dizziness, visual disorders, and memory impairment are among the immediate symptoms that some people have experienced soon after exposure to VOCs.

Reduce indoor air pollution by avoiding interior building products that release volatile organic compounds (VOCs), or other unsafe compounds, and by ensuring that interior spaces are adequately ventilated. Currently, California's Department of Health Services and the California Integrated Waste Management Board are testing products for VOC off gassing. Results from these tests will be used to help guide schools towards healthier material selection.

Many products can contribute to indoor pollution, such as school furniture, carpets, adhesives, paint, finishes, cleaning products, and others. High concentrations of indoor air pollutants can cause illnesses in faculty and students alike, but students are especially susceptible.

Collaborative for High Performance Schools (CHPS)
http://www.chps.net/manual/index.htm#vol2
(Best Practices Manual Volume 2, Introduction to Guidelines Section, Material Selection and Research) CHPS aims to facilitate the design of high performance schools in California - environments that are not only resource efficient, but also healthy, comfortable, well lit and contain the amenities needed for a quality education. CHPS has developed a set of Best Practices Manuals (available at www.CHPS.net) to create a new generation of high performance school facilities in California.

Reducing Occupant Exposure to VOCs From Office Building Construction Materials: Non-binding Guidelines
http://www.cal-iaq.org/iaqsheet.htm
This set of guidelines, created by DHS, makes available numerous resources concerning indoor air quality, including this report on reducing VOCs through product selection.

California Energy Commission, Public Interest Energy Research (PIER) - Reference Specifications for Energy and Resource Efficiency
