Life cycle assessment report : Chemistry building UBC Jarolim, Adam


This life cycle assessment of the Chemistry building at the University of British Columbia is an study to analyze environmental impacts. The information gathered in this study will be used to make future sustainable decisions at UBC. The scope of this study only includes the manufacturing and construction phases, also known as Cradle-to-gate analysis. OnScreen takeoff and Athena's Impact Estimator were used to model and catalogue the materials and impacts from the Chemistry building. An output from the Impact Estimator is the bill of materials, which encompasses all the material quantities. The environmental effects of the materials are then studied to determine what impacts the Chemistry building had during it's initial life stages. A sensitivity analysis was also performed to understand what effect each of the top five most used materials individually have on the environment. This analysis highlights which materials should be switch for alternatives in order to mitigate environmental impacts. Lastly a building performance model was used to investigate what effects improving the building's envelope would have. This model compares the current envelope system to a system that meets a UBC standard and investigates how long the building would have to be in operation to see a return on the initial building envelope improvements.
