Hi Marc, thanks for your question regarding VOCs.

"VOC" stands for "Volatile Organic Compound". The chemical compositions of these substances cause them to be gaseous at normal room temperature and pressure conditions.

While not all VOCs are dangerous to humans, many of them are harmful when emitted in large volumes. They are found in many common construction materials, including paints, adhesives, and sealants. Since they readily evaporate and enter the air stream, they are very difficult to contain once emitted.

Reducing the amounts of VOCs emitted during the construction process and after the building is occupied improves the health and welfare of the construction workers and building tenants.

VOCs and LEED

LEED, a green building rating system, awards points to design teams and construction professionals that specify and utilize "Low-Emitting Materials" for indoor applications. Low-VOC construction materials can specifically earn points for Indoor Environmental Quality Credits 4.1, 4.2, and 4.3 in the LEED New Construction and Major Renovations Rating System.

In order to meet the LEED requirements for these credits, the low-VOC materials should comply with VOC limits set forth in the LEED rating system that is applicable to the building project. These requirements include VOC restrictions created by sustainability-minded organizations, such as South Coast Air Quality Management District, Green Seal Standard, Carpet and Rug Institute Green Label Plus, et al.

Many thanks, and good luck!
