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?

We are working on a project that will install terrazzo and polished concrete flooring. These are both mineral based and are exempt from testing requirements for flooring systems. However, if we will add a colored surface hardener that comes in powder form and is made from cement, sand, additives and pigments. In this case, Will the terrazzo and polished concrete flooring still be exempt from testing?

I have found these products to be inherently inert as well, and not covered by SQAQMD; all of the msds sheets I have seen are zero VOC. I would include the product in the Flooring Adhesives and Finishes section.

Hello John, Do you think that only a VOC emissions testing will not be required for compliance with IEQc4.3? A VOC content test is sufficient in our case?

The VOC testing for the hardener needs to be compliant with the criteria of SCAQMD, but the terrazzo and polished concrete flooring should still be exempt.
