CI-2009 MRc7: Certified Wood 1 point

This ruling addresses two separate documentation paths for MR credit 7: Certified Wood.
The project team is asking which invoices are required to be submitted as documentation for the Certified Wood credit. The invoice required for documentation of MRc7 is the invoice for wood products sold to the project contractors or subcontractors who do not modify the product off-site are required to be submitted. Invoices from farther up the supply chain (documenting the history of the product) do not need to be provided. In the case of a furniture dealer that purchases furniture and installs it on-site and does not have a COC certification, they may provide their invoice to the end user along with a letter from the furniture manufacturer which states the manufacturer COC number and the FSC label (FSC pure, FSC Mixed Credit, FSC Mixed NN%) for each piece of furniture.
The project team is inquiring if the aggregated totals for new wood material costs as defined in the April 2008 wood documentation guidance must be in an invoice from the installer, or if the cost amounts may be submitted separate from an invoice. Yes, documentation of aggregated FSC and non-FSC certified wood may be aggregated and submitted via separate documentation if the following requirements are met:
An alternative documentation process is available for architectural woodworkers (manufacturers of millwork, casework, and furniture) who supply custom wood products to the project. The purpose of this alternative process is to allow FSC-certified materials used in a custom millwork, casework, or furniture package to contribute toward the credit even if the entire package is not eligible to be invoiced with a FSC claim. Documentation for this alternative process must meet all of the following requirements:
- The woodworker (whether an individual or a company) must be FSC CoC certified, and the CoC certificate number must appear on the project invoice.
- The woodworker must install the custom millwork, casework, or furniture.
- The woodworker’s invoice must isolate product costs from installation costs.
- The woodworker must provide a document, separate from the project invoice, detailing FSC-certified wood materials used and total cost of wood materials used. (The woodworker does not need to provide itemized material cost calculations but must maintain calculation records for auditing purposes by the FSC certifying body.)
- The contract cost may include assembly labor but must exclude on-site labor (see MR Overview, Determining Product Cost).
The project team should complete a spreadsheet itemizing wood components by cost and identifying FSC-certified and noncertified components to determine overall contributions to the credit, to be entered into the MR calculator. Calculate the FSC-certified contribution value toward the credit by multiplying the percentage of FSC-certified wood by the overall value of the contract. Calculate the percentage of FSC-certified wood by dividing the cost of FSC-certified wood by the total cost of the wood. Submit the FSC-certified contribution value as well as the total contract amount. Include the woodworker’s CoC certificate number, invoice, and itemized costs.

The inquiry is seeking clarification on whether temporary wood products may be included in the MRc7 calculation, and if so, whether the entire 50% of wood materials for the credit may be met by the temporary wood products. Per the LEED-NC v2.2 Reference Guide, First Edition October 2005, Errata Sheet posted November 17, 2005, as well as the LEED-NC v2.2 Reference Guide, Second Edition September 2006, "wood products purchased for temporary use on the project (e.g. formwork, bracing, scaffolding, sidewalk protection, and guardrails) may be included in the calculation at the project team\'s discretion. If any such materials are included, all such materials must be included in the calculation. If such materials are purchased for use on multiple projects, the applicant may include these materials for only one project, at its discretion." This credit is achievable through the temporary wood products alone, as long as all permanent wood products are also included in the wood total. Applicable Internationally.
