George H. Berghorn is an assistant professor of construction management in the School of Planning, Design and Construction and an adjunct assistant professor of forestry at Michigan State University. He earned a PhD in construction management from MSU and a Master of environmental studies degree from Yale University. Berghorn is a LEED Accredited Professional in Building Design and Construction, and a Certified Green Professional from the National Association of Home Builders. He has worked on funded projects related to the feasibility of building deconstruction and material reuse, barriers to increasing mass timber building construction in the U.S., reuse of salvaged lumber in cross laminated timber, the role of construction activities in aquatic invasive species introduction and spread, building science education, and electric utility training. Prior to his career in higher education, Berghorn was a site superintendent and construction project manager in the U.S. and a policy director for a statewide trade association.
Mass Timber Construction as a Circular Economy Solution – Challenges and Opportunities
In this panel presentation we explore the forest to building construction to use and reuse life cycle of mass timber construction products like cross laminated timber and glulam through a sustainability and efficiency lens. We start with a brief summary of the life cycle from forest to wood product, then compare mass timber and conventional construction whole building life cycle assessments, identify challenges in implementing mass timber construction projects, and highlight opportunities for extending the life cycle by designing for disassembly (DfD) and reuse. Both material and process implications of using mass timber are discussed.
