Future Cities’ Material Flows: Implications of Design, Production & Waste
About the Conference
This virtual conference is co-convened by the Hixon Center for Urban Ecology, Yale School of Architecture, Yale School of the Environment, and the Center for Industrial Ecology and will focus on the potential of mass timber as a primary building material in cities. There is growing evidence that replacing traditional urban building materials such as steel and concrete with mass timber has multiple benefits, ranging from reduced environmental impacts to structural resilience and cost savings. In fact, using mass timber at scale in urban areas offers the chance for much needed short term carbon emission reductions in the building sector; the majority of future population growth will occur in urban areas, and most of the buildings to host this growing population still need to be built. A transition from mineral to biogenic building materials then offers a double carbon benefit, the upstream carbon savings in material production and the long-term carbon storage over a building’s lifetime. This half-day conference will explain the potential of mass timber and how it differs from other construction (session 1) before it explores the environmental implications of substituting building materials (session 2). The audience for this conference includes YSE students & alumni, architects, foresters, practitioners, city planners, developers, and researchers.

Professor Oliver’s initial research focused on the basic understanding of how forests develop and how silviculture can be applied to ecological systems most effectively. Much of this work is incorporated in a book he wrote entitled Forest Stand Dynamics (1990, and update edition in 1996) with a former student as coauthor. He has continued this work; during the past decades he has also examined how this understanding can help resolve scientific, technical, and management issues at the landscape and policy levels. He has worked on computer decision support systems at the stand and landscape levels. He has just published a book, Global Resources and the Environment (Cambridge University Press; 2018; 512 pp; Fatma Arf Oliver, coauthor). Professor Oliver has considerable experience advising public and private forest resource organizations in the United States and abroad.
