The U.S. Green Building Council (USGBC) developed the Leadership in Energy and Environmental Design (LEED) Green Building System to provide guidance and standards for environmentally sustainable construction. According to USGBC, "LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions." Learn more about LEED at the USGBC website. The LEED guidelines for paint and coatings focus on indoor air quality and limiting the amount of volatile organic compounds (VOC) contained in paints and coatings used within the building envelope.
LEED 09 has many programs with varying requirements for paints and coatings. The most common LEED program, LEED 09 - NC , is designed for new construction. In order to earn credit under IEQ 4.2, paints and coatings used within the building envelope must not exceed the following VOC limits.
|Substrate||VOC Limit (g/L)|
|Interior Walls and Ceilings - Flat Coatings||50|
|Interior Walls and Ceilings - Non-Flat Coatings||150|
|Primers - Flat||50|
|Primers - Non-Flat||150|
|All Other Coatings Follow SCAQMD Rule 1113 Limits in Effect on January 1, 2004|
