VOC Content

Yes, but possibly it could come from a technical data sheet that the manufacturer sends directly to the specifier.

Michelle—I beg to differ. If I received such info directly from a manufacture, I would view it with considerable skepticism. The Low-Emitting Materials Calculator column titled "Wet-Applied Products Volume Used" is asking for the quantity (in liters) of product (adhesive, sealant, or coating) that was applied on-site on the interior of the building (for use in a VOC Budget calculation). Manufacturers are so removed from the procurement and application of their products that I would never expect one to have access to this kind of project-specific information. I would only trust quantity data received via the CM or GC from the sub that applied the product. Even then, the data would only be valid once all application was complete. Finally, I believe that this quantity field is only required if a project uses one or more products that exceed the VOC limits stipulated for wet-applied products.

I agree with everything you said. I interpreted the question as a request for VOC content information; not quantity as required for a VOC budget. Quantities would need to come from the builder. Apologies if I misinterpreted.

Michelle, can you let me know if this is correct: For Option 1, you HAVE to enter the volume used of all wet-applied products (e.g., (2) 8-liter containers of paint would be entered as 16 liters). In the end, all wet-applied product volume has to end up with 90% of volume complying. So, if you have one non-complying product but just a tiny bit of it, you may end up at 98% compliance. Even if you know 100% of your products will comply, you STILL have to track volume. Is this correct? The way a team would use Option 2 - which is a nightmare to document - would be if they are not meeting the 90% or 100% threshold requirements for wet applied products, composite wood, and/or flooring. They'd have to use the VOC budget calculator to prove they are below the base case scenario, calculated at the whole-project level. Is this correct? A question which may seem insignificant, but could be important in some instances - do we track what was purchased or what was used? What if 6 tubes of a certain non-complying adhesive is purchased but only half the tube is used? Ideally, we'd document the 1/2 tube. This method requires quite a bit of effort and coordination from the subs and would likely get significant pushback, esp. on a fast-paced project. Thank you!
