Over the past several years, there has been a rise in mass timber construction around the world, demonstrating the strength, stability, and design flexibility of next-generation lumber technologies. To help inform architects, engineers, developers, industry professionals, students and interested parties, reThink Wood has launched the reThink Wood Research Library to serve as the go-to industry resource for those seeking information on the latest advancements in wood’s performance and advantages in the built environment.
reThink Wood is a body of research hoping to push boundaries and shift perceptions about building with wood.
Today, mass timber technologies, including cross-laminated timber (CLT), nail laminated timber (NLT) and glued laminated timber (glulam), are gaining traction in the U.S. for mid-rise and tall wood structures. The publicly accessible and comprehensive reThink Wood Research Library will be frequently updated with the latest research on wood building products and systems worldwide, as well as demonstrate where research gaps currently exist.
“The future of mass timber in the U.S. is really starting to heat up,” said Lucas Epp, head of engineering at StructureCraft. “In the next few years, there will be considerably more mass timber buildings built than we have today. The industry is starting to see that this type of construction is fast, cost effective and sustainable.”
Advocates of CLT say it can be used to construct buildings of equal strength and fire-resistance as those made of steel and concrete. It has also fueled the passions of architects and environmentalists, who believe it to be a much greener method for housing the world’s growing population.

We ask: If the 19th century modern building material technology was associated with steel and the 20th century with concrete, could the 21st be the century of “MCT,” mass construction timber? Wood, one of the world’s oldest (and greenest) building materials, was the de facto construction material in American cities for over two centuries, falling out of favor when non-combustible materials capable of building high and wide emerged.
Today, highly engineered timber, sized to compete with these structural systems, is making a comeback in Europe, especially in Germany and in Austria, where the world’s first 8-story “ply-scraper” was recently completed. Stateside, the Boston Society of Architects recently featured Urban Timber, an exhibit showcasing innovative developments in wood technology and construction, and the U.S. Department of Agriculture is sponsoring a $2M ideas competition for the design of tall wood buildings. Given all of this hoopla, one could assume that we are on the verge of a global timber revolution, yet the U.S. is lagging far behind our European neighbors. In fact, to date, neither the U.S. nor Canadian building codes explicitly recognize mass timber structural systems.
Deeply committed to sustainability, we made the choice to dive feet first into connecting with the past to build the future by employing MCT for the primary structural system of our University of Massachusetts Amherst Design Building. Designed with Equilibrium Consultants, one of the world’s foremost timber engineers, the building will house the university’s Departments of Architecture, Landscape Architecture, Regional Planning, and Building Construction Technology, and is now under construction. Permitted through a variance application using the “alternative” method provisions of the building code, our 87,000-square-foot building furthers the university’s educational mission by incorporating examples of the inherent departments’ design practices. Targeting LEED Gold, it will be among the first MCT structures in the region when completed in 2017.
Laminated technologies, first developed in Europe in the 1980s, are allowing us to fabricate fairly massive timber components for the Design Building using small diameter trees sustainably harvested from managed forests. Our selected timber, black spruce, was sourced from Canada’s Boreal forest region, an area that constitutes the world’s largest land based biome. It is constituted to stand up to fire and maintain its structural integrity.

The American Wood Council has been awarded a $250,000 grant from the U.S. Department of Agriculture (USDA) to conduct research on the fire performance of mass timber buildings. AWC will partner with the National Fire Protection Association’s (NFPA) Fire Protection Research Foundation and the Property Insurance Research Group.
The AWC proposal is intended to advance the construction of taller wood buildings in the United States by demonstrating the fire performance of newer mass timber products. Over the last several years, tall wood buildings have been completed around the world using this new technology – including a 9-story building in London, 10-story in Prince George, Canada, and 14-story building now under construction in Bergen, Norway. These buildings have consistently demonstrated the successful application of mass timber technologies.
“Findings from this project will inform the building community and the insurance industry, providing an increased level of confidence in both the adequacy of this new construction type and when setting fire insurance premiums. This is a new method of construction to insurers, and in order to provide reasonable insurance coverage, they need to understand the performance of the material,” said AWC Vice President of Codes & Regulations Kenneth Bland. Increased use of wood in building construction also holds great promise for improved environmental impacts.
“Innovative mass timber wood products encourage sustainable forestry and capture large amounts of carbon, thereby reducing greenhouse emissions through both sequestration and the substitution of wood for more carbon-intensive products. The construction of tall wood buildings would put America at the forefront of an emerging global opportunity,” said AWC President & CEO Robert Glowinski.
When announcing the USDA 2015 Wood Innovations grant recipients, Agriculture Secretary Tom Vilsack said, “Working with our partners, the Forest Service is promoting deployment of new technologies, designed to support new market opportunities for wood energy and innovative wood building materials.”
