Museum Exhibit Challenges Notion That Wood Is An Antiquated Building Material

For centuries, wood was civilization’s primary construction material, but as the use of concrete, glass and steel grew, wood was largely relegated to flooring and interior paneling.

An exhibition at the National Building Museum in Washington challenges that narrow use. It suggests that tomorrow’s buildings will or should be constructed of wood. The exhibition, “Timber City,” highlights the wide range of benefits offered by cutting-edge methods of timber construction, showing that wood is a modern, strong and versatile material.

The show highlights the two winners of the Tall Wood Building Prize, sponsored by the U.S. Department of Agriculture. “One in New York City and one in Portland, Oregon, are two premier cross-laminated (engineered, pre-fabricated) timber buildings going up right now,” said the exhibition’s curator, Susan Piedmont-Palladino. “They’re similar structures. Both buildings are using this material … in slightly different ways, but the goal is to build right in the middle of the city.”

And that’s what makes timber the perfect choice in a busy district like New York’s Manhattan, where construction speed and efficiency are vital. “Buildings go up very quickly. The materials for the building — the walls and the floors and the ceilings — are manufactured off-site. They come on a truck, pre-fabricated,” Piedmont-Palladino said. “So a work crew armed with power screwdrivers can basically assemble the building extremely quickly. There’s no long-term curing of concrete” needed.

Information panels in the exhibition explain that concrete manufacturing is the world’s third-largest source of greenhouse gases, and that harvesting timber — a renewable resource — has a lower environmental cost than mining the materials needed to make steel and concrete.

Tallest Timber Building In The U.S. Opens Its Doors

The seven-story T3 tower features 220,000 square feet of prefabricated CLT timber panels and nail-laminated timber cladding.

It became the largest timber building in the U.S. when it opened Wednesday in Minneapolis. Designed by Vancouver-based Michael Green Architecture and Architect-of-Record DLR Group, the office building is named T3, which stands for Timber, Technology, and Transit.

“As businesses compete to attract and retain staff, T3 offers a modern re-interpretation of the historic building that appeals to young professionals,” says Architect Michael Green. “It celebrates the robust character of historic wood, brick, stone and steel buildings, but provides state of the art amenities, environmental performance, and technical capability needed for competitive businesses in Minneapolis.”

In addition to being constructed of sustainable lumber, the building will sequester about 3,200 tons of carbon.

StructureCraft, who worked on the project, said the building, which resembles nearby historic warehouses in the district, features a structural system around a fifth of the weight of a similarly sized concrete building. StructureCraft says it was able to construct the 180,000 square feet of timber required in less than 10 weeks.

Focus On Wood Reshaping The B.C. Construction Industry

B.C.’s focus on heavy timber and mass wood construction is reshaping the construction industry, creating a new type of construction expertise, while also showing the private sector that mid and highrise wood structures can make economic sense.

“Since the beginning of this year, we are starting to see more interest from developers in these projects and the City of Vancouver is also interested in them,” said Eric Karsh, structural engineer and co-founder of Equilibrium Consulting Inc., a Vancouver firm that specializes in large timber, engineered structures. “We are now just beginning to see developers seriously consider eight-to-10 story solid wood buildings.”

The City of Vancouver is providing equivalencies such as reduced parking for the construction of wood buildings, which can translate into a plus for developers, he said, and there is the growing realization that the prefabrication approach offered by mass timber construction can expedite construction and reduce costs.

“We are developing details that show these buildings are cost efficient enough and developers are beginning to take notice,” he said.

That interest is a change from earlier attempts to kick-start private sector involvement. In 2012, wood advocate and architect Michael Green and Karsh published the Case for Tall Wood study, which advocated for wood highrises up to 20 stories and spoke with builders and developers regarding wood’s viability for mid-and highrise use.

America’s First Wood High-Rise Building To Debut In Oregon

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.

British Columbia Invests $2.2 Million To Promote Wood In Buildings

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.
