The battle over the 2017 Timber Innovation Act is gaining momentum in Washington, D.C., where two new Senate sponsors and four new Congress members have signed on to it since this past May. The pending legislation would provide funding for research into innovative wood materials and mass timber structures above 85 feet. The bill’s proponents are hoping that it will be an impetus for transforming cities and towns across the country with a bevy of mid-rise and high-rise mass timber buildings.

“I am very impressed with the large cross-aisle support,” Chadwick Oliver, director of Yale University’s Global Institute of Sustainable Forestry, said. “You have Bruce Westerman, a Republican congressman from Arkansas and Peter DeFazio, a Democrat from Oregon who has been on the side of environmental groups. This looks like a bill that is quite serious about moving forward.”

However, the concrete and steel industries are vigorously lobbying to derail the legislation, and have established a website called Build with Strength that contains a detailed critique of the new generation of wood buildings. “It is a piece of legislation that props up one industry over another and we think that it is misguided and dangerous,” Kevin Lawlor, a spokesperson from Build with Strength, said. “We don’t think that it is safe in three-to-five story buildings, and we don’t think that it is safer in taller buildings.”

The wood products industry, the U.S. Forest Service, and other advocates claim that technological advances make the new generation of tall timber buildings more fire resistant. In fact, according to Dr. Patricia A. Layton, director of the Wood Utilization + Design Institute at Clemson University, that is because of the way it chars in a fire: By insulating its interior, an exposed wood beam can actually be structurally stronger than a steel one. “Steel loses its strength at a lower temperature than does wood,” she explained. “If you expose concrete or steel it is combustible, and it does feel the effects of fire.”

Many of the act’s supporters say that allowing buildings to be built from wood technologies such as cross-laminated timber (CLT) will result in a host of economic and environmental benefits. Most of the Timber Innovation Act’s sponsors hail from states where the wood industry is struggling to recoup from the recent housing downturn and also suffering from the decrease in demand for paper that is a result of the increasing digitalization of the economy.
