USDA Mass Timber Material Quantities Final Report

Building Materials

This study explores how mass timber buildings can be optimized for material efficiency and support a regionally-specific life cycle assessment case study of a mass timber office building in the Pacific Northwest. The University of Washington Architecture team defined a reference commercial office building using heavy timber/cross-laminated timber (CLT) to substitute for conventional construction. The School of Forest Resources Team developed regionally-specific LCA models to evaluate the environmental impact of potential CLT production in the Olympic Peninsula.
