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

Test method

Can a flooring system be tested using the latest version of CDPH test method and still comply to NC 2009? NC 2009, option 2, demands that all flooring products meet the testing requirements of California Department of Public Health (CDPH) Standard Practice for the Testing of Volatile Organic Emission from Various Sources Using Small-Scale Environmental Chambers, including Addenda 2004, also known as "Section 01350". Healthcare 2009 requires all hard surface flooring must be tested method according to CDPH Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers, Version 1.1 (2010). In 2010, CDPH updated the 2004 Standard Practice and informed that this 2010 update supersedes prior versions. Therefore, does a flooring system tested by 2010 test method comply to NC 2009?

When LEED references a particular year of a standard, that year's standard stay in place until LEED is updated and not the standard. We only need to go to the newer version of this test standard if we are working in LEED-HC. NC 2009 or v3 stay with the 2004 version of the test.
