Legal Wood

Possible 1 point

Intent

To encourage the use of products and materials for which life cycle information is available and that have environmentally, economically, and socially preferable life cycle impacts. To reward project teams for selecting products verified to have been extracted or sourced in a responsible manner.

Requirements

Option 2. leadership extraction practices (1 point)
This pilot credit is an alternative compliance path to LEED v4 Building product disclosure and optimization: raw materials sourcing - Option 2 (1 point).

Pilot ACP text in bold.

Use products that meet at least one of the responsible extraction criteria below for at least 25%, by cost, of the total value of permanently installed building products in the project.

  • Extended producer responsibility. Products purchased from a manufacturer (producer) that participates in an extended producer responsibility program or is directly responsible for extended producer responsibility. Products meeting extended producer responsibility criteria are valued at 50% of their cost for the purposes of credit achievement calculation.
  • Bio-based materials. Bio-based products must meet the Sustainable Agriculture Network’s Sustainable Agriculture Standard. Bio-based raw materials must be tested using ASTM Test Method D6866 and be legally harvested, as defined by the exporting and receiving country. Exclude hide products, such as leather and other animal skin material. Products meeting bio-based materials criteria are valued at 100% of their cost for the purposes of credit achievement calculation.
  • Wood products. Wood products must be certified by the Forest Stewardship Council or USGBC-approved equivalent. Products meeting wood products criteria are valued at 100% of their cost for the purposes of credit achievement calculation.
  • Materials reuse. Reuse includes salvaged, refurbished, or reused products. Products meeting materials reuse criteria are valued at 100% of their cost for the purposes of credit achievement calculation.
  • Recycled content. Recycled content is the sum of postconsumer recycled content plus one-half the preconsumer recycled content, based on cost. Products meeting recycled content criteria are valued at 100% of their cost for the purposes of credit achievement calculation.
  • Pilot Alternative Compliance Path – Legal Wood
    • Wood products from Certified Sources as defined by ASTM D7612-10 are valued at 100% of their cost for purposes of credit achievement calculation if the following two conditions are also met:
      • 100% of all wood is verified to be from Legal (non-controversial) Sources as defined by ASTM D7612-10. These components include at a minimum, structural framing and general dimensional framing, flooring, sub-flooring, wood doors and finishes.
      • and

      • 70% (based on cost) of all wood used on the project is from Responsible Sources as defined by ASTM D7612-10. These components include at a minimum, structural framing and general dimensional framing, flooring, sub-flooring, wood doors and finishes.
  • USGBC approved program. Other USGBC approved programs meeting leadership extraction criteria.

For credit achievement calculation, products sourced (extracted, manufactured, and purchased) within 100 miles (160 km) of the project site are valued at 200% of their base contributing cost. For credit achievement calculation, the base contributing cost of individual products compliant with multiple responsible extraction criteria is not permitted to exceed 100% its total actual cost (before regional multipliers) and double counting of single product components compliant with multiple responsible extraction criteria is not permitted and in no case is a product permitted to contribute more than 200% of its total actual cost.

Survey Questions

  • where is this project located (city, state/province, country)
  • does the country/region the project is located in have existing laws/regulations regarding legal wood? are they effectively enforced?
  • how much wood, relative to other materials, was used on this project (by cost)?
  • prior to attempting this credit, what was your understanding of illegal wood in the buildings industry supply chain in your region?
  • prior to the work the project team did on this credit, was verified legal wood something that was required in any standard project spec used by the project team?
    • if yes, what specific language was used?
    • if no, did the project team develop standard specification language for future use?
  • What specific piece of this ACP was the most difficult:
    • 100% legality verification?
    • 70% responsibly sourced verification?
    • procurement of certified wood?
  • was legality documentation readily available from your upstream wood suppliers?
    • what documentation were they able to provide?
    • was this the first time that a project team asked the supplier for documentation to verify legality for wood?
  • who, on the project team, was responsible for documentation? did the project team need to hire an outside expert to facilitate achievement?
  • Did this credit influence or change the wood that was ultimately used on the project?
  • One of the goals of this ACP is to assess the feasibility of the creation of a prerequisite around legal sourcing of building materials.
    • How transformational do you think a prerequisite requiring legality verification for forest products would be?
    • How feasible do you think a prerequisite requiring legality verification of forest products would be?
    • How feasible do you think legality verification of all materials would be?
Changes
  • 8/8/2019 - removed "Structure and enclosure materials may not constitute more than 30% of the value of compliant building products."
