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?

NC-2009 IEQc4.1:Low-emitting materials - adhesives and sealants

IEQc4.1 Required information

Hi everyone! 

I´m pretty new at LEED certification process, so I will really appreciate your help. 

We are close to upload the construction submittal on a project we have been working for about 7 years. We were planning to upload the source of VOC data for at least 20% of the materials , by item (not by cost). Is it enough? Is there anything else we can provide?

Thanks for your time!

Yes, VOC data for 20% of your materials, by item. As long as you have included all of your adhesives, including flooring adhesives, that is all that's required.  Good luck!

I'm noticing on version 6 of the credit form for this LEEDv2009 credit that they do not request sources of VOC for data for 20% of materials listed in the form.  Can anyone verify if this is still that case?  I ask since we have an extension to wrap up our last LEEDv2009 project.

Hi Edgar,It's true the requirement went away. But if you have collected the information, it would still be wise to upload it.
