Dear all,
Does we need to integrate glazing area in Option 2 : Budget calculation method ?

FAQs about EQc2:
Are throw rugs subject to the credit requirements?
What are the adhesives and sealants to be included in the documentation?
Is there a VOC budget method for this credit?
What are the limits on the VOC budget method?
Do products applied to the weather barrier need to comply with VOC thresholds?
If one part of my multicomponent wall system is not compliant, can I still get full credit?

Glass is inherently non-emitting, so it can be excluded.

Thank you for your reply. Nevertheless I understood that ALL material, even non-emitting should be enter in the calculator. Is this a mistake ?

Hmm. I'll take a look later today unless someone else answers before then.

Yes, I believe that you are correct. From the Credit Language "Inherently nonemitting sources. Products that are inherently nonemitting sources of VOCs (stone, ceramic, powder-coated metals, plated or anodized metal, glass, concrete, clay brick, and unfinished or untreated solid wood flooring) are considered fully compliant"
If you enter them into the budget as fully compliant they will weight your total towards a higher level of compliance.

Thank you for that answer,this was my feeling too.
This option 2 raises many questions especially for the consideration of all layers of the same coating.
If we apply two layers of the same painting, do you think that we should recognize the paint area twice? This does not increase artificially the level of compliance?

It is definitely an interesting philosophical discussion that is not specifically addressed in the rating system. The v3 budget method used quantity of paint whereas the v4 credit looks at surface area. For that reason I think the most reasonable course of action is to count each unique product in the wall as a layer. Primer and top coat would be separate layers, but top coat paint would only count once regardless of number of coats.
