Life cycle assessment of the Civil and Mechanical Engineering Building

University of British Columbia. Campus and Community Planning

This report contains an in-depth Life Cycle Analysis of the Civil and Mechanical Engineering (CEME) Building at the University of British Columbia in Vancouver, British Columbia. The life cycle analysis scope includes the envelope and structure of CEME from cradle to gate, that is, from the building’s product manufacturing to end of construction stage. The methods used to achieve a detailed analysis included contributions from two authors. The first author included a thorough on screen takeoff of CEME’s level three elements including foundations, walls/floors above and below grade, roof structure and interior partition walls. The second contributor then assessed the quality of the initial study and made improvements to the accuracy of that study. An impact assessment was then performed on each element to determine its contribution by impact category to overall impacts for CEME as a whole. The results of the impact assessment were then compared to 22 other institutional buildings at UBC to determine how CEME equated. It was determined that CEME’s had less of an environmental impact than the majority of other buildings at UBC as it’s impact category values were lower than the benchmark’s value. Furthermore, CEME’s level three element “A23 Upper Floor Construction” contributed the most in all seven impact categories included in the Athena Impact Estimator. Finally, it was discovered that the product stage had a larger impact that the construction stage for all level three elements, it was approximately 80-90% larger in all cases. This report also includes interpretations of the results such as recommendations for LCA use to be put in practice and an author’s reflection of the project and CIVL 498C as a whole.
