Life Cycle Assessment report Thunderbird Old Arena Fan, Dennis; Geyer, Sean; Kernahan, Hillary; Ruddock, Josh


Prior to the 2010 Vancouver Winter Olympics several structures were built for recreational purposes. A life cycle assessment (LCA) was carried out on two of the event arenas built for the 2010 Winter Olympics. One of the sites, the Thunderbird Arena was a renovation of an existing recreational complex. The LCA presented in this report is for the pre-existing complex, which consists of three main buildings. The scope focuses on the materials manufacturing and the construction of the buildings (i.e. maintenance and usage are disregarded) and the results were used to compare the impacts of the materials used during construction to aid with future design decisions. Modeling was conducted using On-Screen Takeoff 3 and Athena Impact Estimator (IE) software. These tools allowed for a Bill of Materials (BoM) to be generated as well as characterisations of the total environmental impacts due to materials manufacturing, building construction, and transportation. The TRACI method was used to report values on fossil fuel consumption, weighted resource use, global warming potential, acidification potential, human health respiratory, eutrophication potential, ozone depletion, and smog potential. It was found from the BoM that the top 5 materials used during the construction were aggregate rock, rebar, galvanized sheeting, steel tubing, and concrete block. A sensitivity analysis was then run on the materials to determine the change in impacts based off a 10% increase in each case. It was found that the most significant change in impact on construction was the 10% increase in rebar.
