FAQs about IEQc4.1 :

Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project?

Do products applied to the weather barrier need to comply with VOC thresholds?

How do I determine what application my product falls under?

How is VOC % less water determined for aerosol adhesives?

Do grout and caulking need to be included, and if so, what is the application category?

Our project didn't use some common adhesive types, and our LEED reviewer asked about this. Are we supposed to justify not using certain adhesives in our documentation?

CI-2009 IEQc4.1:Low-Emitting Materials—Adhesives and Sealants

How do you simplify the VOC budget method for one non compliant

I read the following. However, how do you do this in the template? Will it accept only putting in the amounts for the one product and the offset? Else you would still have to get the quantities for all products and this is very tedious? Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project? Yes, if you have just one non-compliant product, then you can balance it out with just one really good, low VOC product, as long as all your other products meet the requirement. For example, if you have two gallons of non-compliant adhesive that is 100 g/L over its required threshold, then you can balance it out with enough compliant product where you show you are at least 100g/l under the required threshold, thus balancing the VOC budget.

So you want to know if you can game the system this way? As I know it, the VOC budget method is for use on projects where the contractor has incorrectly applied the product or to use when you absolutely are backed into a corner.

I don't agree. Where does LEED say that it is only to be used in the case of contractor mistake? I've used this approach before, it is an alternate compliance path but my understanding is that those are absolutely available to project teams if they choose.

From the FAQ's (above this section) Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project? Yes, if you have just one non-compliant product, then you can balance it out with just one really good, low VOC product, as long as all your other products meet the requirement. For example, if you have two gallons of non-compliant adhesive that is 100 g/L over its required threshold, then you can balance it out with enough compliant product where you show you are at least 100g/l under the required threshold, thus balancing the VOC budget.
