Mass Timber Competition

Three Mass Timber Buildings - UMass, Platte 15 and Outpost


Building to Net-Zero Carbon

Designed to expand the use of mass timber in the United States, the Mass Timber Competition: Building to Net-Zero Carbon showcases mass timber’s application, practicality, commercial viability, and role as a natural climate solution that reduces the carbon footprint of the built environment. The Competition is intended to help expand the use of mass timber building solutions and support increased employment in advanced wood products design, engineering, construction, supply chain, and manufacturing sectors.

The SLB and USDA fund the competition. The funding supports costs associated with the use of mass timber or mass timber hybrid building systems and construction. Funding also helps project teams overcome barriers to the use of a new building material and system, most notably the costs of analyzing design and engineering alternatives and verifying that these solutions comply with applicable code(s).

2023 Competition – Entry Period Now Closed

The entry period for the 2023 Mass Timber Competition closed on May 5, 2023. Public announcement of the winners will be made during the week of October 16, 2023.

2022 Competition Recap and Project Updates

In June 2022, the SLB and USDA Forest Service announced the winners of the first competition. Six projects were chosen for their ability to demonstrate mass timber’s innovative, scalable applications in architectural design and to highlight its significant role in reducing the built environment’s carbon footprint. The winning projects, which shared $2 million in total funding, are listed below. A blog post profiling the winners can be found on Think Wood.
