How Reclaimed Wood Contributes to LEED Certification

LEED (Leadership in Energy and Environmental Design) certification is the most widely used green building rating system in the world. If you're pursuing LEED certification for a project, reclaimed lumber can contribute meaningful points across several credit categories. Here's how.

Materials and Resources (MR) Credits

MR Credit: Building Product Disclosure and Optimization — Sourcing of Raw Materials. Reclaimed wood qualifies as a "reused" material under LEED v4 and v4.1. Using reclaimed materials contributes to the threshold for earning up to 2 points in this credit category. The more reclaimed material in your project (by cost as a percentage of total material cost), the more points you can earn.

MR Credit: Construction and Demolition Waste Management. If your project involves deconstruction of an existing building and you salvage lumber for reuse (either in the new project or by donating/selling to a reclaimed materials dealer), this contributes to waste diversion goals. Diverting 75% or more of construction waste earns 2 points.

Innovation (IN) Credits

Projects that go above and beyond in their use of reclaimed materials can pursue Innovation credits. For example, a project that sources 100% of its wood from reclaimed sources, with full provenance documentation, could potentially earn an Innovation credit for exemplary performance in material reuse.

Regional Priority Credits

In some regions, including the Northeast, material reuse is identified as a Regional Priority credit, which can earn bonus points. Check your project's LEED region to see if this applies.

Documentation Requirements

Earning LEED credits with reclaimed lumber requires proper documentation. Here's what you need:

• Invoices and receipts: Showing the quantity and cost of reclaimed materials purchased
• Material provenance: Documentation of where the reclaimed wood was sourced (building name, location, date of salvage)
• Chain of custody: Records tracing the material from source to project
• Product data: Species identification, dimensions, and processing information

At New York Lumber, we provide all of this documentation as standard practice. Every order includes provenance information and detailed material descriptions that can be submitted directly to your LEED consultant.

Practical Tips

• Engage your reclaimed lumber supplier early in the design process — don't wait until construction is underway
• Coordinate with your LEED consultant to identify which credits reclaimed wood can contribute to in your specific project
• Keep meticulous records of all reclaimed material purchases, deliveries, and installation
• Consider reclaimed wood for multiple applications (flooring, paneling, structural elements) to maximize the percentage of reused material

LEED certification is increasingly expected in commercial construction, and reclaimed wood is one of the most straightforward ways to earn credits while creating a more beautiful, sustainable building.
