FAQs about MRc6 :

I have supporting manufacturer documentation for the FSC wood used on our project. Is this enough to document this credit, or do I need invoices as well?

Can products labeled “FSC Recycled” or “FSC Recycled Credit” contribute towards MRc7? What about "FSC Mix" percentages that refer to recycled content?

Does FSC-certified wood automatically contribute to IEQc4.4 as a low-emitting material?

We are using a lot of reclaimed wood. Should we include this in our MRc7 calculations? What about wood that is already installed on the project, in a renovation? What about wood products with recycled content?

Does FSC-certified bamboo products count towards this credit?

A product has FSC-certified veneer, but a non-certified core. Can we prorate the MRc7 contribution of this product based on the cost of the veneer?

Should wood used on site features such as benches or a gazebo be included here?

Is there a minimum quantity of wood that must be used on the project to qualify for this credit?

How does this credit treat materials that come from animals such as wool or leather?

What building components are typically purchased with renewable materials to reach the 2.5% credit threshold?

A manufacturer is claiming that certain trees, e.g. balsa, acacia, mesquite, can be harvested within 10 years, and thus contribute to this credit. Is this acceptable?

We are pursuing IEQc4.5 from LEED-CI as an ID credit. Are we then required to include the cost of furniture in MRc3–7?

What building components are typically purchased with FSC content to earn this credit?

We’re having trouble getting FSC wood within our budget. Can we use products with another forestry certification?

Do I need to provide invoices for all of the new wood products purchased for the project, or just FSC wood products?

NC-2009 MRc6:Rapidly Renewable Materials

Bio-based building materials - foam for use under concrete

I have a project for which we are pursuing Platinum and have an opportunity to use a bio-based material (12"+/-) as a filler under pan deck and concrete. Half of this building is raised access floor and all of the floor slab has been poured at the -14" level. I am looking for a material to fill in the non-raised access floor areas that is bio-based. It is a sealed area but concrete surrounded, thus moisture with related decay and odor are a concern. Is there a bio-based foam product that would work? Or something similar?

Charles, we have an exhaustive list of materials qualifying for this credit, including biobased foam insulation, in GreenSpec. You can see a list of products in the GreenSpec Products block in the right column of this page.
