One of our contractors has a question about the VOC budget method. If we have a large number of materials in our building, do we need to list all of them in the budget, or can we leave the majority of compliant products out, and just include enough compliant products to offset the very few non-compliant liters of material on site? (e.g if we have 100 extra grams of VOC in one product application, can we include one additional material where we have 100 fewer grams than the allowable by virtue of it being a zero or extremely low VOC material) - this way we can save the time of collecting quantities of all the compliant materials, yet still insure we are below the VOC budget - adding all the other quantities will add more grams of material, but for each liter used, we will add the same or more grams of allowable materials. Thoughts?
