FAQs about IEQc4.1 :

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?

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?

In FAQs for IEQc4.2 I found an information that the actual weather barrier does not need to comply with the credit. I understand that we can treat EPMD Membrane as weather barrier. Does the adhesive used with the EPMD membrane needs to comply with IEQc4.1? If yes, how to classify it?

There has been an addenda issued, but I cannot find it right now. The CaGBC in Canada has worded it as such: "Sealants, adhesives and primers that are considered part of the air barrier for the building can be excluded from the requirements of credit IEQc4.1 - Low-emitting materials: Adhesives and Sealants for LEED Canada NC or CS 2009 projects."
