4.2.2 Toxic Gas Emissions

4.2 Indoor Air Quality

Comply with industry established performance-based standards, specifying goods with low chemical and particle emissions for use indoors: primarily building materials, interior furnishings, furniture, cleaning/maintenance products and electronic equipment. Monitor quality of outdoor air delivery and design for filtering systems, particularly relevant for developing countries.

Specify high performing paints, coatings, adhesives, sealants, carpets, composite woods, agrifiber, air filters, furniture and equipment that have low emissions of Volatile Organic Compounds (VOCs), formaldehydes, respirable particles, styrene and other airborne pollutants.

Comply with industry standards and certification procedures including test methods, maximum allowable emissions levels, product sample collection and handling, testing type and frequency, and program application processes and acceptance. (See link to

Low toxic gas emissions standards will lead to higher productivity, profitability and reduced potential for future litigation. In hospital design, it can contribute to shorter length of stay for patients, thus reduce cost of care.

Contributes to increased occupant health, well-being and comfort.

Refer to allowable VOC-content levels, measured in g/L. Allowable levels can be found in any version of the LEED reference guide.
