Life cycle assessment improvements of Frederic Lasserre building at University of British Columbia Russell, Andrew


Previous cradle to gate life cycle assessment work on the Frederic Lasserre building of UBC was restructured and improved. This study took the previous Lasserre Impact Estimator model, reorganized the buildings construction to CIQS format, thoroughly inspected the previous model for material, property type, and geometric flaws, carried out improvement strategies regnerated the IE model with results, and finally developed a campus wide benchmark for comparative assertion. From life cycle stage results it was clearly demonstrated that the product stage weighs heavily on impact for a cradle to gate analysis. From a CIQS elemental standpoint A22-Upper Floor Construction, A32-Walls above Grade and B11-Partitions are noted as hotspots in the Lasserre building contributing the majority of the seven impact categories assessed. The Lasserre building in comparison to the developed benchmark performed below average as a whole and had particularly weak performance in elements B11-Interior Partitions and A32-Walls above Grade. Global warming potential was determined to be the most salient impact from class aversion survey results. This led to a GWP versus construction cost (2013 $). In this comparison it was found that older UBC buildings tended to perform better than newer ones. The results and recommendations from the study and all others in the collective project aid towards the operation of LCA methods in practice at UBC. Useful for the Universities sustainability ambitions and targets, the study has also provided students with the applicable hands on experience at tackling the expanse nature of a building LCA.
