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

Does anyone know if a screed that is applied to concrete slabs prior to installing carpet tiles is considered for this credit and or IEQc4.1/4.2? The screed is a self-levelling smoothing compound used as an underlayment applied onto interior concrete slabs prior to installing carpet tiles as the final floor finish.

I would say no, as screeds, as well as self-leaving concrete are cementatious materials; neither SCAQMD 1113 or 1168 reference these materials. As well, I have yet to come across any of these products with any VOC content.

I would agree with John.
