Stefan will be presenting recent research work on the life cycle performance of LEED versus conventional buildings at UBC. Life cycle data shows how buildings, built over the last 90 years, reveal surprising trends in the evolution of the campus building stock in terms of embodied impacts. The recent construction of the CIRS building used over 600m3 of wood in the main structure. This design innovation has reversed a decades- old trend of increasing construction emissions by returning to the use of wood, hence using the past to inform the present. In contrast to embodied impacts, the operational performance of buildings has changed relatively little over 90 years. Recently constructed buildings at UBC, including LEED Gold certified, do not always operate more efficiently than older buildings.


Stefan Storey is a PhD student at the Institute of Resources, Environment and Sustainability, where he is collaborating with the UBC Sustainability Office along with research architects at Perkins+Will. He is co-founder of the LCA Alliance, an life cycle advocacy group at UBC Vancouver campus. Recently, Stefan joined the UBC Sustainable Building Science Program, an interdisciplinary training program where he continues his work on life cycle assessment methods to quantify the financial and environmental impacts of commercial buildings.
