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?

NC-2009 IEQc4.3:Low-Emitting Materials—Flooring Systems

German AgBB in LEED version 3 and 4

In a LEED v3 project a manufacturer is supplying information that his carpet is complying with AgBB 2015. For LEED v4 this would be sufficient (as far as I know newer standards are accepted). If I read the LEED v3 requirements strictly the manufacturer would need to prove compliance with the "Standard Practice..." but may use the AgBB measurements (3 and 7 day available). So at least in theory GBCI reviewers could reject the documentation.

Personally I think the carpet should be fine if, it is sufficient to achieve LEED v4 credit it should comply with LEED v3 as well.

Does anyone have experiences, tips or warnings?

NB: we would not want to use the full version 4 credit to replace version 3 IEQc4, as all documentation so far and all reporting processes are built around version 3.

Thanks, Jens
