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

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

Raised floor with gypsum panel - exempted from FloorScore?

Does anyone having project that uses raised floor with gypsum panel as flooring system ? Can I suggest that gypsum is exempted from FloorScore certificate as they are primarily mineral-based like ceramic tiles and concrete and its production process undergoes high temperature treatment ?

William, There are many gypsum products around that pass the requirements of meeting the low-emitting standard CA 01350. You can find some of them on sites like GREEENGUARD and SCS or manufacturers will actually have test reports that show they comply.

Hi William, Is the gypsum your finish flooring system? If so, I've never heard of that before. Is there something over the gypsum or is it part of the mechanical system somehow? Just wanted to get some clarity. It's only finish flooring systems that would be included.
