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

Wood Flooring from Italy

We are installing wood flooring on our project and it is manufactured in Italy. As they do not have floor score certification - How can this product be documented? Their website says all their products meet formaldehyde standards as per Japanese main standard. Here's the web link of their certifications. http://www.stile.com/Stile/certificazioni.aspx All the remaining products on the project meet the standards. Not sure how to document this wood floor? Can anyone please advise.

The flooring doesn't have to meet Floorscore - that is a compliance path. The flooring needs to show compliance to the CA 01350 criteria (which is what Floorscore's requirements are) and that requires showing the minimization of 35 chemicals. Formaldehyde is one of those chemicals, but it isn't the only one. If they are referring to the Japanese F Star program levels then they have multiple different levels of formaldehyde compliance and the testing, modeling and criteria is very different from the CA 01350/Floorscore way of doing things.

Thank You Josh! Yes it is Japanese F Star program and their products are rated F (4) stars. which means the products have less than 0.3g/l. can we still document the flooring for the credit as a special circumstance?

Sheela, If it is solid wood flooring it does not need to be tested and it does not need to be FloorScore. See above for the credit description. However, if it is an engineered wood product then you would need to make sure it was FloorScore or that it showed compliance with CA 01350. Check out this link for an example of other FloorScore engineered wood products: http://www.scscertified.com/products/index.php

Thanks Lauren. Where can i find the requirements for CA standards?

Fri, 02/03/2012 - 15:18

Hi Sheela, You should be able to find the requirements for testing in the Reference Guide. "All flooring products must meet the testing and product requirements of the California Department of Public Health Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda. Mineral-based finish flooring products such as tile, masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated solid wood flooring qualify for credit without any IAQ testing requirements. However, associated site-applied adhesives, grouts, finishes and sealers must be compliant for a mineral-based or unfinished/untreated solid wood flooring system to qualify for credit."
