Developers and other project owners in pursuit of low-carbon construction methods are increasingly choosing mass timber for their projects. But to do so in larger and taller buildings, they must reassure civic leaders, fire and rescue services and insurance underwriters—along with the public—that these projects are fire safe. New research, supported by the National Research Council of Canada (NRC), Canadian Wood Council and federal and provincial governments, is doing just that. A recent series of tests, dubbed the Mass Timber Demonstration Fire Test Program, show, even in worst-case fire scenarios, mass timber buildings perform similarly to noncombustible construction. The calls to construct more buildings with mass timber to help tackle climate change are growing. …In a recent report, Canada’s biggest bank points out that constructing taller wood buildings and swapping concrete and steel with mass timber represents a potential 12% to 25% drop in carbon emissions.
