Life cycle assessment of Frederic Lasserre Building at University of British Columbia Ranjbar, Sahar

Abstract

The LCA analysis of Frederick Lasserre building was conducted using the OnScreen TakeOff Pro software to perform analysis on the structural drawing of the Frederick Lasserre building. The data collected from OnScreen TakeOff pro are then entered into the Impact Estimator (IE). The environmental impact of the data is then quantified through IE which uses the Athena LCI database and the TRACI impact assessment methodology. Bill of Material (BoM), Summary Measures and Absolute Energy reports which were generated by IE were used in the environmental impact analysis of the Frederick Lassere building. These reports were used to perform sensitivity analysis and building performance on the Frederick Lasserre building. BoM report which is a list of the materials which were used in construction of the building and summary measure report data were used in sensitivity analysis. Through this analysis it was found that rebar has the highest environmental impact out of five other materials which were chosen from the Lasserre building for the purpose of sensitivity analysis. The building performance analysis was done on the original Frederick Lasserre building and the upgraded Lasserre building. The upgraded Lasserre building surface areas where insulated so that the building meets the REAP standards. It was found that the energy payback period of the improved Lassere building would be 4 months. From the analysis, it is recommended that further research be conducted into envelope performance upgrades.
