This is a follow up to a thread in 2012 regarding paint used to stripe parking stalls (enclosed parking structure). The response was that the paint needed to comply with VOC limits and the respondent thought that 100 g/L for traffic coatings would apply. Can anyone confirm that traffic coatings with a VOC limit of 100 g/L applies to this situation? Thanks

By definition, parking garages are not conditioned space and not included in the Gross Floor Area. If the garage is open to the outdoors at all times, or if it is enclosed and provided with ventilation only, it is exempt from IEQc4. Underground parking garages that are “inside the exterior moisture protection envelope,” but “not technically interior space,” are exempt from IEQc4 because they are “unconditioned, non-regularly occupied space.” See LEED Interpretation #1767: http://www.usgbc.org/leed-interpretations?keys=1767

However, if you were to include a traffic coating in documentation for IEQc4.2 on a CS-2009 project, the VOC limit set by SCAQMD-1113-2004 is 150g/L for traffic coatings, which SCAQMD defines as “coatings formulated for or applied to public streets, highways, and other surfaces including, but not limited to, curbs, berms, driveways, and parking lots.”
If you paint interior floor markings using ordinary floor paint, the VOC limit is 100g/L for floor coatings (“opaque coatings that are formulated for or applied to flooring; including but not limited to decks, porches, gymnasiums, and bowling alleys, but do not include Industrial Maintenance Coatings”).

Thank you Jon for your comments. I see 100 g/L published on the SCAQMD table of standards, updated 9/6/13. I belive the 150 g/L is an older standard.

As you say, the September 2013 version of SCAQMD-1113 is the most current, but for IEQc4.2, LEED Projects must base credit compliance upon the versions cited in the rating system for which the project seeks certification.
LEED-2009 NC, CS, CI, Retail, & Schools all cite the version of SCAQMD-1113 that was in effect on January 1, 2004 (http://www.usgbc.org/sites/default/files/SCAQMD%20Rule%201113%207-9-04.pdf ).
LEED-2009 for Healthcare cites the version from July 1, 2008, and LEEDv4 cites the June 3, 2011, version. Many of the VOC limits set by SCAQMD-1113-2013 are lower than the VOC levels required to achieve LEED Low-Emitting Material credits.

An interpretation allows products compliant with the CARB 2007 SCM for architectural coatings to meet credit requirements. This is one mechanism for capturing specialty products that don't really fit the short list in the original credit language. http://www.usgbc.org/node/1732511?view=interpretations
Traffic Marking Coatings have a VOC limit of 100 g/L. http://www.usgbc.org/sites/default/files/CARB%202007%20SCM%20-%20Final%2...
SCAQMD Rule 1113, as it existed on January 1, 2004, places Traffic Coatings at 150 g/L. While this is the baseline for credit conformance, CARB compliant products are readily available. http://www.usgbc.org/sites/default/files/SCAQMD%20Rule%201113%207-9-04.pdf
