Nadav (and all) - In our local jurisdiction we are required to comply with BAAQMD requirements for VOC content. Do you know if BAAQMD VOC regulations in general are more stringent than SCAQMD's? Early version of LEED required BAAQMD reg 8, rule 51 as the standard for sealants, but that standard was dropped in NC 2.2. I'd heard that the standard was too hard to meet. Thanks.

Hi Marian, I don't know that off hand. Is it not easy to line them up and compare? If it's tricky, I can try to get someone here to do that--or we can ask one of the IAQ ubergeeks out your way--I bet Anthony Bernheim or Hal Levin could tell us...Anyone else know the answer?

Thanks Nadav. I will be putting together a small spreadsheet comparing the two just from the point of view of VOC content. I will be happy to share it with you.

Hi, I'm getting the same question now too. I'll do the side by side comparison to know for-sure, but does anyone have current experience with this? Thanks!

Hi, Deb! The original post is from the 2009 version of LEED, which has been retired. If you're working on the v4 or v4.1 LEM credit, I recommend posting on one of those forums because people are much more likely to see it.

Just out of curiousity, I did a quick review. I am familiar with the SCAQMD Rule 1168 regulation for sealants and adhesives. Many manufacturers treat Rule 1168 as the de facto national standard for for field applied architectural sealants other than small containers (16 oz threshold) that are regulated by CARB. By way of comparison, the Bay Area rule is ancient and dates back to 2001. Rule 1168 has gone through many evolutionary steps in the last 20 years. That has led to addition of niche categories and generally lower VOC limits. Rule 1168 has a few niche categories with higher limits than the general 250 g/L Rule 51 limit. It has some categories with lower limits and a default category that is the same at 250 g/L. For convenience: https://www.baaqmd.gov/~/media/dotgov/files/rules/reg-8-rule-51-adhesive-and-sealant-products/documents/rg0851.pdf?la=en&rev=7cf8dc673a4f41629984727defad9b55 http://www.aqmd.gov/docs/default-source/rule-book/reg-xi/rule-1168.pdf At any rate, this is not germane to LEED since the Bay Area rule is not incorporated by reference. Note to moderators: It would be nice if we could post screenshots.

Re. being able to post screen shots: we have taken that under advisement! Thanks, Dwayne. :-)
