FAQs about IEQc4.3 :

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?

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

asphalt use within the envelope

I am looking for any information on the use of asphalt paving verses concrete within a building envelope and how the VOC content could effect LEED credits. Since it is not a typical use, there is really no data to help provide direction. Thanks for any guidance offered.

Asphalt within a building envelope doesn't sound likely to be low-emitting and likely to comply. But if you want to go for it, I would reference the hard-surface flooring requirements in the credit language above. Seems pretty straightforward.
