Concrete Form Release Oil VOC limit

Hi Ian, it appears most team do not consider form release oil pertinent to this credit. See comments here: http://www.leeduser.com/credit/nc-2009/IEQc4.2?page=1&ip_login_no_cache=af06d6cc3175577fcd7be84a85087993. Still, if you feel safer attempting to meet a specific threshold, BuildingGreen has listed several low VOC products here: http://www2.buildinggreen.com/category/builder-categories/structural-systems-components/foundations-footers-and-slabs/concrete-for David

Play it safe… The LEEDuser comment thread referenced above is for LEED-2009. The 2004 SCAQMD Rule cited in LEED-2009 did not include a VOC limit for Form Release Compound. Under LEED-2009, it might have made sense to ignore Form Release. However, the newer SCAQMD Rule & CARB measures used in LEEDv4 DO regulate Form Release VOCs. Furthermore, the thread argued that Form Release Compounds were usually temporary coatings, applied early and likely to off-gas before the building has been enclosed. However, since I am not a chemist, I cannot be certain how much time to allow for off-gassing. Even then, I have been on several projects where some interior concrete work continues even once the building is weather-tight. To be safe, treat any coating, adhesive, or sealant applied within what eventually becomes enclosed space as an “interior” product, even if application occurs while the building is still open. This protects the health of workers applying the product and preserves indoor air quality. Finally, as David notes above, low-VOC products are readily available, so there is no reason not to require SCAQMD-compliant products regardless of when they are used. Also note that LEEDv4 for Schools & Healthcare require the same VOC limits for both interior & exterior products.

Can anyone clarify what's required for exterior products? Does this just mean meeting VOC limits for wet applied exterior products or does it also require CDPH evaluation of say exterior insulation? Thanks

Only LEEDv4 for Schools & Healthcare limit emissions of exterior products. Go to the "Credit Language" tab on the LEED-NCv4 for Schools EQc2 page to see exterior requirements: http://www.leeduser.com/credit/Schools%E2%80%93NC-v4/EQc2#lang-tab The Schools credit language tab includes a few extra paragraphs & bits of text that you won't find on the NC credit language tab above.

Ah thanks. Don't know how I missed it! It'd be easier to catch if it was in the table...

The second link from Jon Cliffords post, with low VOC products is not working, anyone have the updated location?

Per GBCI:  Form-release compounds should be included in the paints and coatings category if the product is used within the building. Note, being permanently installed is not something that is explicitly addressed in the EQ section. If the team is attempting the paints and coatings category, per SCAQMD Rule 1113, effective June 3, 2011, form-release compounds have a permissible VOC limit of 250 g/L. Also, they will be subject to VOC emissions evaluation.    My Note:  LEED4.1 references South Coast Air Quality Management District (SCAQMD) Rule 1113, effective February 5, 2016 and the VOC content limit is 100 g/L.
