Abstract: CLT offers the potential to reduce greenhouse gas emissions by using timber, which requires much less energy to produce than steel or concrete and naturally sequesters carbon through its lifetime. However, there is a gap in the literature and a lack of general understanding about how much carbon CLT sequesters compared to the carbon emitted in the manufacturing process and in creating the adhesives used, as well as how the carbon value is calculated. This project analyzes and summarizes relevant literature and will create six case studies to illustrate the embodied carbon impacts of various kinds of mass timber buildings. In doing so, it aims to reduce confusion in the sector and assist designers and developers in making informed decisions regarding future green buildings.

Abstract: Mass timber products are often selected for their perceived sustainability advantages, and a lifecycle analysis for an Oregon-based CLT manufacturing facility is being completed. This project will assess the environmental impacts of mass plywood panel manufacturing, a new product that has become available commercially in Oregon in 2018. It will examine material flow, energy type and use, emissions to air and water, solid waste production and water impacts for the MPP manufacturing process on a per unit volume basis using a cradle-to-gate lifecycle assessment process. The data will be available for stakeholders to use for informational and learning purposes and to assist in determining the sustainability of mass timber building projects.

Abstract: This project assesses and compares the environmental impacts of forest products used in the old (1999) Peavy Hall teaching building at Oregon State University and the new mass timber building that will be completed in 2018. The findings will be incorporated in updated guidelines for life cycle analysis that fully take into account the role of reclaimable wood building products.
