Life cycle analysis : Fred Kaiser Building

University of British Columbia. Sustainability Office

In this report, Fred Kaiser Building was analyzed for life cycle assessment. This analysis includes quantity takeoff and data input by using OnScreen Takeoff and Athena Impact Estimator. TheOnScreen Takeoff Software creates a material list which includes the material type and quantities for data inputs in Athena Impact Estimator. The Impact Estimator uses the TRACI impact database to quantify the environmental impacts of the building assemblies. The results of impact estimator include Bill of Materials and summary measures by life cycle stage and assembly group. The summary measures by life cycle stage showed eight categories of environmental impacts which are associated with the manufacturing stage of the building. A sensitivity analysis was base on the five anticipated materials to investigate the relative impacts of each material overall environmental impact. It was determined that the most influential component out of the five chosen was the concrete with 30 MPa strength and average flyash. In addition, an analysis was conducted to determine the amount of materials needed to improve the current buildings energy performance to UBC’s Residential Environmental Assessment Program. Operating energy data was obtained from the UBC building services department and a spreadsheet template was used to determine the improvement of operating energy given material upgrades. It was determined that it will take approximately 36 months to recover the energy input for adding insulation materials from energy saving.
