Earth Systems Science Building : ESSB life cycle assessment Baumann, Robert; Ho, Hilda; Valdebenito, Maria Jose


This report presents the Life Cycle Assessment (LCA) of the new Earth Systems Science Building (ESSB) for which construction is expected to be completed in the year 2012 at University of British Columbia (UBC) in Vancouver, British Columbia. The report shows the impact of the materials used for the structure of the complete building; specifically in raw material extraction, manufacturing of the construction materials, and construction of the envelope of the whole building. Furthermore it also takes into account the impact of the transportation of these materials. To measure the quantities of the material used in the building and to estimate the environmental impact of such materials and activities two software were used. In addition, a sensitivity analysis was performed on five materials to determine how much it affects the environmental impact to increasing each material by a factor of 10%. The results of the analysis are presented in graphs and tables and show that concrete and glazing are responsible of the greatest environmental impacts of the building.
