I am very confused on what standards I should be using for this credit (and IEQ 4.1). My project was registered on 9/21/2011, my understanding is that I can use the NC & CS standards per the erratum (in lieu of the LEED for Schools requirements), so am I supposed to use the GS-11 Third Edition (August 17, 2011) for Architectural paints and coatings, GC-3 January 7, 1997 for anti-corrosives and anti-rust, and the SCAQMD rule 1113 7/1/08 for clear wood finishes, floor coatings, stains, primers, and shellacs? My contractor is trying to assert the standards indicated in the 2009 edition reference guide (GS-11 1993, GC-03 1997, and SCAQMD 2004) are the limits that need to be met. Are we to use the newer versions or those indicated in the reference guide? Any guidance / clarifications would be greatly appreciated.

Todd, if your project was registered after the addendum was issued, then you are bound to use it.

Thanks Tristan, just to verify, the addendas I can find on USGBC.com do not indicate I need to use the current versions of the above referenced guides. So I can use the VOC limits in the SCAQMD 2004, GS-11 1993, and the GC-03? I can't find anything in an addendum from the USGBC that indicates I need to use the most current version of the aforementioned regulations. Does anyone have different information?

I think I misunderstood your original question. You do not need to follow the most recent versions of the standards, just the most recent LEED requirements relative to your registration date, and note that there was one major update since LEED 2009 was launched.

Let me clariy...the SCAQMD rule 1113 2004 table of standards VOC limits has 9 effective dates listed from 1/1/98 thru 7/1/08. Am I required to comply with the VOC requirements up to the 1/1/04 effective date or do I need to comply with the limits through the 7/1/08 effective date? Specifically: Waterproofing concrete / Masonry Sealers - Limit 400, lowered to 100 on effective date 7/1/06 (per the table). Should I use the 400 limit or the 100g/l as the 100 g/l is per effective date 7/1/06? this is confusing and will have a huge impact on my project (registered 9/21/11). Thanks an I hope my question makes sense.

Todd, see the table here on NC IEQc4.2 for the correct referenced standard, by date, including the note at the bottom of the table about when those limits became applicable in LEED.
