…Since the concept of modern engineered-wood buildings was proposed more than a decade ago, the idea has caught on in a big way. Today, there are around 50 wood and wood-hybrid buildings proposed, under construction or completed, according to the Council on Tall Buildings and Urban Habitat (CTBUH). In its report, Tall Timber: A Global Audit, CTBUH noted that the phenomenon has gained worldwide interest. Why construct wood high-rises in the 21st century? In addition to these buildings offering fire protection and seismic resistance, structural strength, easy assembly and weighing far less than concrete and steel, these structures are environmentally friendly: a ton of concrete used in high-rise construction spews a ton of carbon into the air during production; a ton of wood used in a wood mass building has the potential to remove from the air and store up to two tons of carbon for the life of the project.
