FAQs about EQc2 :

Is all solid wood considered inherently non-emitting? I’ve seen sources that say only solid wood flooring counts as inherently non-emitting.

Our building is atypical, and the walls and ceilings are not clearly defined. How should we classify these components? 

Are throw rugs subject to the credit requirements?

If a ceramic tile receives a top coat after it is manufactured, is it exempt from the credit requirements?

What are the adhesives and sealants to be included in the documentation?

I'm looking for a certification that tells me if a given product will meet the LEED v4 requirements, but I don't see one in a given product area. Am I missing something?

When products claim that they meet California Section 01350, does the product also meet LEED v4 requirements for low-emitting materials?

How do I know if a product complies with LEED v4 or if it was tested under an older non-compliant standard?

In past versions of LEED, it was easy to specify VOC limits. Is the specification process the same for LEED v4?

Is there a VOC budget method for this credit?

What are the limits on the VOC budget method?

Do products applied to the weather barrier need to comply with VOC thresholds? 

If one part of my multicomponent wall system is not compliant, can I still get full credit?

NC-v4 EQc2:Low emitting materials

Japanese F Four Star system for Low-VOC flooring?

I am based in Asia and here many Japanese flooring products have "F Four Star" Certification. An "F Four Star Product" will have a maximum average formaldehyde emission of 0.3mg/L based on  but as far as I can tell the testing method is not the same as CDPH or the European/other standards listed in the reference guide.

Does anyone have success in using "F four star" materials for LEED? Is there any information about its LEED compliance somewhere?

If not I am assuming it would not be compliant as a Low emitting material.

The Japanese F Four Star label is about formaldehyde only. LEED requires low VOC emissions as well. So you are right, this is not compliant as a Low emitting material, sorry.

Thanks Reinhard, I also noticed that about the Four Star label.
