FAQs about IEQc4.3 :

If I have no flooring products in the scope of my project, can I earn this credit?

How do I handle a polished concrete floor?

Should mineral-based finish flooring products (without any integral organic-based coatings and sealants) and unfinished/untreated solid wood flooring be documented on the IEQc4.3 LEED Online form, even though they are exempt from certification requirement

On a renovation, should flooring that is previously installed be subject to the credit requirements?

One flooring adhesive we are using falls under both IEQc4.1 and IEQc4.3, and is over the VOC limit. We are using the VOC budget method to meet IEQc4.1 requirements, but are we automatically disqualifed from IEQc4.3?

The credit requirements are allowed to exempt unfinished wood flooring from the credit requirements, but wood flooring is almost always finished. This is confusing!

I have an international project and my flooring products aren’t tested using any of the above standards. How can I tell if they still comply?

I am on aproject that is installing some savage wood flooring panels that were removed and saved during demo. Can I list the unfinished wood as Exempt per the credit language, and then list the VOC content of the wood stain that will be applied to it separately on the LEED Form? I know this is not technically un-finished wood, but the wood panels that we are receiving to install are unfinished at time of installation, and will be field-finished with a low-VOC stain. And as the wood flooring is salvage material, I have not backup information stating that it meets the testing criteria of the credit. Is my assumption on documenting this credit correct?

Hi Mariah, I would assume so. If the wood flooring was in use at least a year prior to your salvage it would have offgassed any VOC issues associated with the initial installation. If it's solid wood, and you list the new stain. You would have to make a narrative explanation in Special Circumstances to support the exclusion. If it's an engineered wood product, however, you might have an issue with EQ4.4.

Yes, salvaged wood is excluded from needing to be included. The stain that you mentioned, however, would need to be accounted for.

Thanks! One more question - Would I list my explanation of wood flooring and tile flooring on the project under "Special Circumstances" or "Alternate Path." Above in the "Bird's eye View" it says to list it as an Alternate path, but I am not sure on this.

I think either is fine. Often I just leave products like this off my list of products completely but it never hurts to provide a narrative explanation either as an attachment or in the Special Circumstances area.
