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

Wood stair

Good morning, We have a wood stair (wooden steps covered with another wood species) that is manufactured by the millwork contractor. The scale is a custom made design. Would we have to ask for special testing of the product to validate this special product? Thanks, best regards. Serena

Hi Serena, I am assuming the stair treads will be finished on site. If so, special testing for the assembly should not be required, but VOC requirements for adhesives used in its construction have to meet IEQc4.1 and subsequent coatings have to meet IEQc4.2.
