LEED™ and Wood

Forest Stewardship Council Certified wood is required for LEED-NC MR Credit 7. Although future editions of the LEED Rating System may allow certification by other organizations, at present the FSC certification is the only one accepted for LEED Certification. Achieving this credit requires that at least 50 percent of the woodbased materials in the project be FSC-certified. The computation of percentages must include all products made of solid wood, wood chip, or wood fiber, including furnishings and non-rented temporary construction such as formwork, bracing, and pedestrian barriers. BSD SpecLink includes FSC-certification as an option in most of the major wood sections in Division 06 - Wood, Plastics, and Composites.

In order to achieve this credit you must not only specify FSC-certified wood, but you must compute the total cost of all wood-based products (materials only) as well as determine what percentage of composite products are made of wood. You can exclude salvaged and refurbished materials and the cost of any post-consumer recycled wood portion of any product. Since these must be actual costs, not budgeted costs, the costs must be obtained from the Contractor.

Several new contract administration forms designed to aid in this process have been added to SpecLink this quarter. The first is 013516.01, LEED Material Cost Summary — to get the overall costs from the Contractor. The second is 013516.02, LEED Wood-Containing Product List — a checklist for the Contractor to indicate for which products he has submitted form 013516.04, LEED New Product Content Form. That last form has spaces for the manufacturer or supplier to indicate the percentage of wood-based content, as well as recycled content and rapidly renewable content, and for the Contractor to certify the cost of the product. These new forms are accompanied by Section 013516, LEED Submittal Forms, covering the procedures, and other forms intended to aid in achieving LEED credits for local and regional products, rapidly renewable content, and reused products.

This is the second in a series of articles on the LEED Materials and Resources (MR) credits, which are among the credits that must be addressed via the specifications.
