Life Cycle Analysis : Forest Sciences Centre Lin, Chu

Abstract

In this paper, Life Cycle Analysis (LCA) is carried out to assess the environmental impacts of the Forestry Science Center (FSC), which is located at the University of British Columbia (UBC). LCA processes and methodologies applied are discussed in detail. The scope of this project is defined as cradle-to-gate. In particular, takeoff is done by using OnScreen and impacts are estimated by using Impact Estimator (IE). Due to the limitation of the software and lack of the construction drawings of the building, uncertainties are introduced into the final results. Sensitivity analysis is performed for five specific building materials of FSC, in order to achieve a better understanding of the contribution to the environmental impact. In conclusion, concrete has the most significant impacts on the overall results. Furthermore, building performance is carried out to explore the payback period of envelope upgrades in terms of energy consumption. Recommendation is then made regarding to the future renovation to FSC or similar building type constructions. Note this project is part of a regionalized study of buildings at UBC, which is also the largest LCA analysis run by students.
