Explanation
Temporary wood products cannot be included in the calculations for the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices.
This is because the credit only applies to permanently installed building products, not to products purchased for temporary use on the project1. The other options are false. If any temporary wood materials are included in the calculation, they must be excluded from the total value of permanently installed building products1.
Non-certified wood materials do not contribute to other credits, unless they meet other criteria such as recycled content or regional materials2. FSC-certified wood materials purchased for more than one project cannot be applied to other projects seeking LEED certification, unless they are reused or salvaged materials3.
