Based on Green Seal GS-11 (1993) the VOC limit for flat primers is 50 g/L. The Second Edition of GS-11 (2008) distinguishes between the Primer/Undercoat and Topcoat allowing for 100 g/L for primers/undercoats. The team is seeking to meet the intent of this credit by complying with the updated GS-11 2008 relating to the primers. All other paints and coatings fall below the VOC limits established in GS-11 1993. Is this approach acceptable?
The LEED-NC v2.2 Reference Guide, Third Edition October 2007, states that all primers must meet the VOC limits for non-flat paint. The alternative standard is therefore not acceptable as a substitute for the current requirement. It should be noted that as needed, a project team can elect to complete a VOC budget to demonstrate compliance. Please refer to page 356 of the LEED-NC v2.2 Reference Guide for additional guidance.
