A new bill from Congress would establish performance driven research for advancing tall wood building construction in the U.S.
The “Timber Innovation Act” would:
· Authorize the Tall Wood Building Prize Competition through the U.S. Department of Agriculture (USDA) annually for the next five years
· Create federal grants to support state, local, university and private sector education, outreach, research and development, including education and assistance for architects and builders, that will accelerate the use of wood in tall buildings
· Authorize technical assistance for USDA, in cooperation with state foresters and state extension directors (or equivalent state officials), to implement a program of education and technical assistance for mass timber applications
Recent advances in technology, engineering and safety have made it possible to build taller wooden buildings using newly-developed mass timber products, like cross-laminated timber. In the last five years, 17 buildings between seven and 14 stories have been built using heavy timber construction globally. Canada, Norway, Australia, the United Kingdom, Italy, Sweden and France all have constructed and occupied multiple tall-wood buildings.
Other countries have already been considering wooden skyscrapers. Researchers presented the Mayor of London with plans for an 80-story wooden building just a few weeks ago.
Multiple organizations in the U.S. wood industry, including The American Wood Council (AWC), American Forest Foundation (AFF), Binational Softwood Lumber Council (BSLC) and Southeastern Lumber Manufacturers Association (SLMA), have all announced strong support for the bill.

Wood is a go-to material for floors, doors, furniture, and now, a skyscraper—the very first of its kind in the U.S. Construction on Portland, Oregon’s wood high-rise, Framework, is slated to begin this October. The 12-story mixed-use building—a collaboration between local firm Lever Architecture and real-estate developer Project—will be made primarily from timber. Thomas Robinson, Lever Architecture’s founder, says his company is interested in “exploring the relationship between materials, experience, and the environment—how the way we build impacts the way we live and the environment as a whole.”
To highlight the innovative design, the structure will be centered around a visible vertical core and capped with a roof deck framed by wood columns. Flexible, sturdy, and lighter than materials like concrete or steel, timber has a high strength-to-weight ratio. Framework’s design includes cross-laminated wood panels, engineered of stacked lumber, for floors and ceilings, and glue-laminated timber for beams and columns.
Inside, a double-height community space will feature a public exhibition documenting the building’s creation and impact, plus a second-floor garden terrace. Visitors will be able to roam retail spaces on the ground floor, while above there will be five floors of offices and five floors of affordable housing.
The “forest to frame” philosophy behind the building reflects its relationship between urban construction and rural lumber manufacturing. This project creates more opportunities in both industries, which were gravely affected in the recession. “Framework stands as a model for sustainable urban ecology,” says Robinson. And there are copious environmental benefits: Buildings made primarily of wood have significantly lower carbon emissions and use less energy than those made from traditional materials. Earlier this year, the U.S. Department of Agriculture took notice. It solicited designs for a tall wood building competition, and the Framework team won an impressive $1.5 million grant to fund further research and development—the structure is expected to be finished by December 2017.

We get so excited about Cross-Laminated Timber (CLT), the fancy plywood on steroids that we talk so much about on TreeHugger. But in fact, there is a much older technology for building with wood, that warehouses and factories were built out of 150 years ago with a fancy new name: Nail-Laminated Timber, or NLT. It used to be known as heavy timber or mill decking and is drop-dead simple: you just nail a pile of lumber together and voila.
Lucas Epp of Structurecraft stunned the audience in a presentation at the Wood Solutions Fair in Toronto, showing extraordinary projects built out of the stuff. Because while CLT is great stuff, it’s pretty new in North America, it’s expensive, and it’s not fully understood by the building inspectors. Whereas if you are doing a simple span, NLT does the job just fine, it’s a lot cheaper, can be made by anyone with a hammer and has been in the building codes forever.
It’s now being used in a 210,000 square foot, seven story office building in Minneapolis, where the developer, Hines, wanted “the warmth of wood and the embrace of green construction techniques and materials” to attract the tech and creative sector of the market. It also goes together much faster than a conventional steel or concrete building.
Heavy timber office and warehouse construction fell out of favor early in the 20th century after major fires in a number of cities caused the switch to concrete and steel noncombustible construction. The development of effective sprinklers has reduced that risk, and concerns about the carbon footprint of concrete have made renewable wood look a lot more attractive.

Portland is growing up—adding high-rises, increasing density, and pricing many people out. But two local firms are exploring a state-of-the-art building material that could help solve the city’s affordability problem, create living-wage jobs in rural communities, and help save the planet. It’s wood.
Right now, Portland-based LEVER Architecture and real estate development firm Project^ are designing a 12-story mixed-use wood building in the Pearl District that will be made primarily of a material called cross-laminated timber (CLT).
That’s an unheard of height for wood structures, which top out at six stories in most of the US. And it’s not the project’s only unique attribute. Five of those stories will be affordable housing, something Portland desperately needs.
LEVER and Project^ have partnered with Beneficial State Bank (which owns the property at 430 NW 10th), Albina Community Bank, and the housing agency Home Forward on the development, which they’re calling Framework.
The team’s ideas received national attention: In September, the US Department of Agriculture awarded the project a $1.5 million grant—money that will help alleviate the cost of proving to state and local building authorities that tall wooden buildings can meet safety requirements for earthquakes, fires, and other perils.

The British Columbia provincial government says it is investing $2.2 million in the Wood First program to promote the use of B.C. wood both locally and internationally, and help advance innovative wood-building systems and value-added wood products.
The funding is being awarded to six industry trade associations and institutions with proven records in research, development and marketing of wood products and skills training to carry out Wood First activities. They include:
• BC Wood Specialties Group – $558,910
• Canadian Wood Council – $770,109
• University of British Columbia – Centre for Advanced Wood Processing – $359,166
• University of British Columbia – Centre for Interactive Research on Sustainability – $65,000
• FPInnovations – $428,928
• Design Build Research Institute – $51,762
Funding from the Province will be supplemented with additional funds provided by industry.
Wood First is focused on advancing the use of wood in B.C. Since the program was launched in 2009, wood use in the mid-rise and non-residential construction sectors is increasing and recognition of wood as a preferred building material continues to grow. A recent survey of B.C. engineers, architects and builders confirmed that 40% are increasing the use of structural wood and 77% believe B.C. is well positioned to export its products and knowledge.
