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?

Our team has asked the question if both MRc6 and MRc7 can both be entered together for credits.  The project has FSC certified wood throughout the project and for MRc6 the FSC Certified Wood materials are 2.7% of the materials budget which would qualify for 1-point.  Concerning MRc7 the calculations shows 99.6% certified wood credits which earns 1-point.  Does our building qualify for 2-points on these credits?

Thanks in Advance, Rich

Hi Richard, Please take a look at LEEDuser's Viewpoint on this credit (MRc6). You'll see that wood materials are excluded from contributing to the credit; they're not considered RAPIDLY renewable, just renewable. So that FSC wood just contributes to MRc7. Nadav

I wanted to mention that I've read USGBC docs which mention some wood is considered rapidly renewable but would need documentation from harvester. ie. Aspen and Poplar. However on our project we found that the poplar growing cycle exceeded 10 years.

I guess i should have also said some products could be both FSC certified (or % partially) AND rapidly renewable (or partial%) such as: https://www.buildsite.com/pdf/tectum/Environmental-Marketing-Bulletin-M-81-Tectum-Products-and-LEED-761383.pdf Whether or not Tectum's Aspen is considered "rapidly renewable" per LEED based on the statement on the doc at link above is not quite clear. I'd call mfgr for a confirmation of 10 yr harvest cycle.
