Theoretical VOC content

Jeffry, doesn't sound legit to me. Leaves too much to chance. LEED is looking for the actual VOC value for the applied product. I would at least look for specific assurance that this theoretical value applies to the product.

Any state or regional air quality management district uses regulations approved by USEPA as a means to reduce area source ozone precursors. Every regulation in existence allows for VOC determination by calculation using supplier data and the formulation or by testing through Method 24 and other regional methods approved by USEPA. A calculated VOC content is legally acceptable to regulatory agencies and equally subject to civil or criminal enforcement. LEED incorporates the regulations by reference and does not require determinations beyond those required by regulation. It is common practice for project teams to request verification letters from manufacturers. If you are not confident in their assertion, take this additional step for the sake of documentation.
