The Sustainable Forestry Initiative Inc. (SFI) announced today that SmartLam, LLC, is the first U.S. manufacturer of cross laminated timber (CLT) to be certified to the SFI 2015-2019 Chain-of-Custody Standard. SmartLam is also the first manufacturer to produce CLT in the U.S.
SmartLam manufactures CLT for a variety of applications, including floor, roof and wall systems. SFI’s Chain-of-Custody Standard helps companies address the growing demand from governments, customers, and consumers for responsibly sourced forest products.
CLT is the next-generation of engineered wood products. Extensively tested and already widely used in Europe, CLT has vast applications for construction, industrial matting and bridging. Architects and builders choose wood because it looks great, has numerous environmental characteristics – including renewability – and it’s easy to work with. In addition, trees absorb carbon dioxide from the atmosphere as they grow, sequestering and storing the carbon while producing oxygen which reduces greenhouse gases and improves air quality.
“At SmartLam, we make CLT, but we like to tell our clients what we really sell is time. CLT increases construction speed and reduces a project’s cost and carbon footprint. Now, with certification to the SFI Chain-of-Custody Standard, we can also offer our clients supply chain assurance that our products are sourced from well-managed forests that are third-party certified to SFI’s rigorous standards,” said Casey Malmquist, President and General Manager at SmartLam.
SmartLam produces CLT at its Columbia Falls facility in Northwest Montana and is part of a global movement to use wood in tall buildings. Advances in technology are producing more engineered wood products and mass timber products that increase the capabilities of building with wood.

Mass timber is sprouting up in cities in North America and abroad. After years of feasibility studies and design proposals, buildings six stories or taller constructed primarily from pre-engineered wood products are being considered in cities around the world.
In London, one proposal, called the Splinter, would rise to 100 stories. In Chicago, Perkins+Will (in collaboration with Thornton Tomasetti and the University of Cambridge) has designed an 80-story high-rise with 300 duplex apartments. If built, River Beech—a key component of P+W’s master plan for the Riverline development—would be made almost entirely from mass timber.
So-called “plyscrapers” are still a tiny sliver of nonresidential construction. In the past five years, only 17 buildings seven stories or taller have been completed worldwide, mostly in Europe and Canada. Six more have started construction, according to the American Wood Council.
Mass production of timber for high-rise construction is still in its infancy in North America. Specifying these products in the U.S. faces resistance from insurers, regulators, and code officials. Steel fabricators and concrete suppliers disparage mass timber for taller buildings on the grounds of safety and durability.
Proponents cite the speed at which tall buildings can be constructed using pre-engineered wood and mass timber’s ability to sequester carbon. Joey-Michelle Hutchison, RA, LEED AP BD+C, CSBA, Associate Vice Principal, CallisonRTKL, says, “The role of mass wood is going to grow because of the demand for sustainable design.” Researchers from Yale and the University of Washington, in a study published in the Journal of Sustainable Forestry (March 28, 2014), postulated that using wood substitutes for constructing buildings (and bridges) could save 14–31% of global CO2 emissions.

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.

WoodWorks, a proponent of large-scale wood construction in the U.S., launched an updated version of its free carbon calculator, adding more options for buildings made from cross-laminated timber (CLT) and other mass timber products. The addition reflects rising interest in large scale wood building construction.
WoodWorks, which receives finding from the U.S. Department of Agriculture as well as timber companies and forest products manufacturers, promotes use of wood products as a means to store carbon, instead of building materials such as cement and steel that require fossil fuel energy to manufacture, a move that can help reduce greenhouse gases.
“The carbon calculator is a useful tool for building owners and designers who’d like to gain insight on the environmental value of alternate designs,” said Bill Parsons, Senior National Director of the Architectural & Engineering Solutions Team at WoodWorks. “It also provides information that allows them to express the carbon benefits of their wood building projects.”
To calculate the carbon benefits of a wood building, users access the carbon calculator at www.woodworks.org/carbon-calculator and enter nominal wood volume information. The calculator then estimates:
• How much time it takes U.S. and Canadian forests to grow that volume of wood
• The amount of carbon sequestered in the wood products, and
• Greenhouse gas emissions avoided by not using more fossil fuel-intensive materials.
• It also uses the U.S. Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator to equate the total carbon benefit to number of cars off the road and home operational energy.

The U.S. Department of Agriculture’s Forest Service Chief Tom Tidwell today announced over $8.5 million to expand and accelerate technologies and strategies that promote the use of wood in commercial construction, heat and power generation, and other wood product innovations that also benefit forest health. Federal funds will leverage more than $18 million in investments from 42 business, university, nonprofit and Tribal partners in 19 states, for a total investment of $27 million.
“We are looking for opportunities to reduce forest restoration costs and create more jobs through strong forest products markets,” said Chief Tidwell. “This funding supports improving forest health on the National Forest System lands and other forested lands and promotes the economic and environmental well being of rural communities.”
The awarded funds will stimulate the use of hazardous fuels from National Forest System lands and other forested lands to promote forest health while simultaneously generating rural jobs. This year, 77 proposals were received for the Forest Service’s Wood Innovations grant program, highlighting the expanding interest and use of wood as a renewable energy source and as an innovative building material.
Healthy markets for forest products help the nation’s forests mitigate some of the impacts of climate change. Research has demonstrated that wood products from responsibly managed forests outperform other building materials in measures of greenhouse gas intensity, air and water pollution and other environmental impacts. Responsibly-sourced forest products also provide income for private landowners that keep their land forested and supports needed investments in forest management to provide clean water, wildlife habitat, and other resources millions of Americans depend upon.
Today’s announcement supports USDA’s Building Blocks for Climate Smart Agriculture and Forestry-a comprehensive effort to provide America’s farmers, ranchers and forest landowners with the tools and resources they need to combat climate change. Through this work, USDA expects to reduce net emissions and enhance carbon sequestration in soils and forests by over 120 million metric tons of CO2 equivalent per year by 2025-the equivalent of taking 25 million cars off the road or offsetting the emissions produced by powering nearly 11 million homes each year.
