At last week’s AIA Conference in Chicago, Softwood Lumber Board (SLB) and USDA Forest Service announced the six winners of their $2 million 2022 Mass Timber Competition: Building to Net-Zero Carbon. According to a statement from SLB, the winning proprosals—selected by an independent jury of experts in the fields of architecture, engineering, construction, real estate development, forestry, and sustainability—exemplify “timber’s innovative application in architectural design…and its significant role in reducing the carbon footprint of the built environment.”
Competition guidelines dictated that the proposals utilize sustainably-sourced timber (ideally domestically harvested and manufactured) and can be easily repeated or scaled. “These six winning designs will serve to advance not just our body of knowledge for mass timber construction," said SLB chief marketing officer Ryan Flom. "They will inform the growing shift towards building for occupancy well-being, resilience, and a minimal carbon footprint.”
