Abstract

As the population continues to grow in China's urban settings, the building sector contributes to increasing levels of greenhouse gas (GHG) emissions. Concrete and steel are the two most common construction materials used in China and account for 60% of the carbon emissions among all building components. Mass timber is recognized as an alternative building material to concrete and steel, characterized by better environmental performance and unique structural features. Nonetheless, research associated with mass timber buildings is still lacking in China. Quantifying the emission mitigation potentials of using mass timber in new buildings can help accelerate associated policy development and provide valuable references for developing more sustainable constructions in China. This study used a life cycle assessment (LCA) approach to compare the environmental impacts of a baseline concrete building and a functionally equivalent timber building that uses cross-laminated timber as the primary material. A cradle-to-gate LCA model was developed based on onsite interviews and surveys collected in China, existing publications, and geography-specific life cycle inventory data. The results show that the timber building achieved a 25% reduction in global warming potential compared to its concrete counterpart. The environmental performance of timber buildings can be further improved through local sourcing, enhanced logistics, and manufacturing optimizations.

Susan Jones, FAIA, LEED BD+C, is a practicing architect and the founder of atelierjones, an architecture and urban design firm. Founded in 2003, the firm’s work entwines design, research, and community engagement to create projects of urban reclamation: of sites, buildings, materials, waste, and ways of living. With her clients and her staff, her projects seek out sites and materials with inherent but underutilized value – to harvest their embodied energy, their catalytic power for owners and communities, and their beauty. In 2015, atelierjones completed the highly acclaimed CLTHouse, one of the first in the US, and was recently selected to design Pike Station, a highly sustainable live/work loft project targeting net-zero water use. atelierjones’ Bellevue First Congregational Church, also one of the larger commercial CLT projects in the US, is under construction and scheduled to be completed in early 2016.

Jones’s work has been recognized by numerous national, regional, and local design awards, including an AIA National Honor Award. Her work has been published nationally and internationally. Licensed in over 15 states, she has been a visiting design professor and critic at numerous universities. In 1999, she was made the first woman partner of the large firm, nbbj. She resigned her position to start atelierjones in 2003.

Jones earned her B.A. from Stanford in Philosophy, and her M.Arch from the Harvard GSD in 1988. She became a Fellow of the AIA in 2010 and was awarded a UW Runstad Research Fellowship in 2013. Originally from Bellingham, Washington, she has traveled extensively, living in San Francisco, Boston, Vienna, Berlin, Catania, Sicily, and Sri Lanka. Currently she lives in Seattle with her husband, Marco, and their two teenage children, Rogan and Domenica.
