About Mass Timber
Mass timber, short for “massive timber,” uses engineered soft wood lumber species as the key structural element for large-scale projects. This building material presents several benefits, namely the significantly lower levels of embodied carbon especially when compared to steel and concrete. In addition to the potential this material offers for climate mitigation-of particular importance in an industry contributing 70% of all greenhouse gas emissions- building with mass timber also presents opportunities for faster construction time, better on-site worker health and safety, support for sustainable forestry practices, and more.
Mass timber markets in Europe and Canada have been growing significantly over fifteen years, but the US market is still nascent. Barriers to accelerated adoption include understanding how to build with this material, building codes, and regional supply, to name a few. The BSA is collaborating with several partners on different mass-timber related programs to contribute positively to this need for education, innovation, and implementation.
