The MSDS for one component of a 4-part sparkproof/conductive flooring system lists a theoretical VOC content level (i.e. as packaged) and an As-Applied content level. The As-Applied value is significantly less than the Theoretical value and satisfies the LEED requirement, whereas the Theoretical limit does not. The other components in this system list only the Theoretical values, all of which are below the allowable limits. Although I would be inconsistent if I was to use the As-Applied value for the one component and the Theoretical values for the other three, it seems to me that the As-Applied value is the appropriate value when the concern is how VOC impacts indoor air quality. Has anyone come up against a similar circumstance?

The VOC content and VOC emissions are two related but different things. VOC content is the amount of VOC in the material. VOC content is regulated by the OTCs (if you're in an OTC). VOC emissions impact air quality and this is what is limited by LEED. It is likely your as-applied value is referencing the VOC emissions but you should call the product's technical reps to confirm.

I have a similar question. The VOCs are stated (on a product that is part one of a two part product) as 356 g/l as supplied and 25 g/l as applied. Do I use the 25 g/l as applied for the VOC level for LEED NC v2009?
Side note: In this case the part two is made by another company and isn't really the exact part 2 that the 25 g/l VOC is based one. So I'm going to ask that they use Part 2 by the same mfgr.
Thanks,
Debra
