100% certified wood

Hello, Abdalla - Per the Reference Guide Correction from July 19, 2010, FSC mixed credit counts as 100% FSC certified wood. If the material is listed with a percentage, then that percentage must be used in the calculations. The actual language from the correction: List all new wood products (not reclaimed, salvaged, or recycled) on the project and identify which components are FSC certified. The cost of all new wood products, both FSC certified and not, must be tallied. Develop a spreadsheet to calculate the amount of new wood and the amount of FSC certified wood permanently installed on the project. Wood products that are not FSC certified and those that are identified on invoices as FSC Pure and FSC Mixed Credit should be valued at 100% of the product cost unless the product is an assembly in which case only the new wood portion of the product counts for credit, see the guidance for assemblies in this credit. Wood products identified as FSC Mixed (NN)% should be valued at the indicated percentage of their cost. For example, a product identified as FSC Mixed 75% should be valued at 75% of the cost. Entities that install an FSC-certified product on the project building/site (typically project contractors or subcontractors, but also furniture installers and the like), do not require CoC certification as long as they do not modify the product's packaging or form except as is required for installation. Contractors and sub-contractors that temporarily possess FSC-certified material prior to installation should be careful not mix or contaminate the FSC-certified material with non-FSC-certified material.

The detailed response here has prompted more discussions. The basic question is--In order to achieve 100% FSC wood credit, does 50% FSC mixed and 50% that is 100% FSC-certified add up to attaining 100% for exemplary performance? Is the project ineligible for exemplary performance because of the portion of the "mix" that is not FSC?
