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

Elevated Floors. Do they need Floorscore?

Hi, We have lots of projects that are seeking EQ c4.3 under LEED C&S v3 and they all have elevated floors in the owner scope. In Brazil, we have 3 kinds of elevated floors (by composition): 1. Cement and aluminium floor 2. Polypropylene floor 3. Sand and calcium sulfate floor The questions are: 1. Do all of them need to have a Floorscore certification (if they are the owner scope?) in a LEED C&S ? 2. Is Greenguard acceptable to comply to this credit as a second option for Floorscore? Thank you.

Just as a disclaimer - I am the Technical Information & Public Affairs manager for GREENGUARD Environmental Institute. Anderson - On 10/19/2009 the USGBC did rule that GREENGUARD Children & Schools certification shows compliance to all IEQc4.3 credits due to the certification showing compliance to CA 01350's requirements.

Hi Anderson, All flooring options would need to be included. However, I'd take a closer look at the credit requirements. Each flooring type needs to meet its own kind of requirements. For instance, only resilient flooring falls under the FloorScore requirement. CRI Green Label plus is the requirement for carpet. And exposed concrete floors need to have sealants that meet the credit's requirements. Aluminum isn't included within the credit's requirements. After taking an additional look at the credit requirements, please let me know if you have any more questions. Good luck! Lauren

In my opinion I think that Anderson has in mind raised flooring, which could be covered by any floor-covering system (either carpet, tiling or vinyl etc.). I believe his question, and mine as well, is if the raised flooring systems (double flooring, elevated flooring or whatever it can be called) need to be evaluated under this credit. Does this credit cover only those floor layers that are walked on? I believe that is true...
