LEED-NC version 2.2 Rating System, MR Credit 7, Certified Wood, page 58 states: "Use a minimum of 50% of wood-based materials and products, which are certified in accordance with the Forest Stewardship Council's (FSC) Principles and Criteria, for wood building components. These components include, but are not limited to, structural framing and general dimensional framing, flooring, sub-flooring, wood doors and finishes. --Only include materials permanently installed in the project." Is this regulation that narrows LEED credit achievement to permanently installed wood materials subject to any errata sheets, administrative rulings, interpretations, etc. that allow non-permanently installed wood materials to be included in the calculations of FSC certified wood for this credit? Also, assuming that the 50% required for credit achievement is met, please clarify 1. whether this point can be earned by including temporary wood products in the calculation of FSC certified wood products (in addition to the permanently installed wood products), and 2. whether this point can also be earned with achievement among the temporary wood products alone (without any FSC certified wood among the permanently installed wood products but by including the non-FSC-certified permanently installed wood products in the base amounts of wood products).
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.
