For architects, builders, and developers pursuing LEED (Leadership in Energy and Environmental Design) certification, reclaimed lumber is a powerful tool for earning points across multiple credit categories. Here is a practical guide to maximizing the LEED value of reclaimed wood in your projects.
Applicable LEED Credits
Reclaimed lumber can contribute to several credit categories in LEED v4 and v4.1:
MR Credit: Building Product Disclosure and Optimization
Reclaimed lumber qualifies under the sourcing of raw materials option. Products that include recycled content, salvaged materials, or bio-based materials can earn points here. Reclaimed wood is classified as a salvaged/reused material, which is valued highly in the LEED framework.
MR Credit: Construction and Demolition Waste Management
When sourcing reclaimed lumber from a demolition or deconstruction project, the salvaged materials contribute to the waste diversion rate. LEED awards points for diverting 50% or 75% of construction and demolition waste from landfills. Lumber salvaged from an existing structure on the project site is particularly valuable here.
MR Credit: Building Life-Cycle Impact Reduction
Projects that reuse existing building elements, including structural and non-structural components, can earn credits for reducing the lifecycle environmental impact. Reclaimed lumber used in place of new materials demonstrably reduces the project's embodied carbon footprint.
Regional Priority Credits
In some regions, the use of locally sourced salvaged materials may qualify for regional priority bonus points. Check with your local LEED resources for region-specific opportunities.
Documentation Requirements
To claim LEED credits for reclaimed lumber, you will need to provide:
- Chain of custody documentation: Where the wood came from (source building/structure), when it was salvaged, and how it was processed.
- Quantity documentation: Board footage or volume of reclaimed material used, expressed as a percentage of total materials by cost or weight.
- Vendor certification: A letter or certificate from the reclaimed lumber supplier (that is us!) confirming the salvaged nature of the material.
- Photos: Documentation of the source structure and the salvage/deconstruction process.
We provide all of this documentation with every commercial order. Our chain-of-custody tracking system follows each batch of lumber from source to delivery.
Cost Considerations
A common misconception is that reclaimed lumber is always more expensive than new. While premium reclaimed species like American Chestnut do command higher prices, many common reclaimed species -- hemlock, pine, Douglas fir -- are competitively priced with comparable new materials, especially when you factor in the LEED credit value and the marketing benefits of sustainable construction.
Many developers find that the added value of LEED certification (higher rents, faster lease-up, premium positioning) more than offsets any additional material cost.
Working with Us
We have experience supporting dozens of LEED-certified projects across New England. Our team understands the documentation requirements and can work directly with your sustainability consultant to ensure a smooth certification process. Contact us early in the design phase so we can help identify the best opportunities for incorporating reclaimed lumber into your LEED strategy.
