Bruce - I believe that would fall under the ceramic tile adhesives criteria which is 65 g/l less water of VOC content. It can also show compliance with the emission criteria of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda (CA 01350).

Thanks for your reply Josh but grouts are not adhesives and the CDHS protocol doesn't apply to NC 2009. Only in LEED for Healthcare does it specifically reference grouts being compliant with ceramic tile adhesive and then the only reference is to 1168 and Prop 65 and not CDHS. I think the values are easily attainable but the reference seems to be arbitrary. Kind of like "and by the way......."

Bruce,
Where would you put grout then? From my understanding, that is where they fall in other LEED projects that I have seen.
Additionally, emission criteria has been used within LEED NC projects for both 'wet product' credits before. The largest LEED reviewer in the southeast has been doing this for years, due to the fact that the emission criteria is the main way called out for compliance in LEED for Schools 2009.

In fact I've petitioned the ARB to add "grout" (as well as several other materials) to it's list and definition of materials and then referenence in the appropriate table. As a specifier you look for definitive data and not inferences. By the way, kudos to UL Environment and their website. Anyone attempting Pilot Credit 43 needs to put it in their Favorites!
