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?

Dear All, I am working on a LEED project in Europe. Our architect is applying several products with Cradle to cradle certificates. Is there a chance these certificates can be used as an alternative to demonstrate compliance under IEQc4? Many thanks for your response!

Isolda! People have been telling me all my life that we would meet one day. Who know that it would be over a LEED question. Not very tragic, is it.The answer is no, as C2C does not address emissions in the way expected under this credit. There is an ID credit path for C2C products if you use enough of them—it's something like 2.5% of the materials budget.

You might want to reference the LEED-CI IDc1.1 CIR (4/9/07) Cradle to Cradle Certified Products. The CIR requires Cradle to Cradle Certified building materials and products for 2.5% of the total value of all building materials and products used in the project, based on cost. The "cost value" of products for the purposes of this calculation will be discounted by 50% for Silver level products and those identified only as "technical or biological nutrients", and doubled for products certified at the platinum level.

Ah - Green Building, a modern day fairytale ;-) Nice to (virtually) meet you, Tristan! Thank you both so much for your reply. I know where not to focus too much attention. Kind regards, Isolda
