The Life Cycle Assessment of the UBC Faculty of Pharmaceutical Sciences and Center for Drug Research and Development was performed in order to evaluate its environmental impacts. This building is currently under construction and in order to attain the most reliable data and to evaluate their performance and impacts on the environment, more accurate data collection is required. Which itself requires more accurate and up to date drawings and models. This project was done through modeling the building using On-Screen Takeoff and Athena Impact Estimator software. Since this building is under construction, BIM model was found helpful and more updated than structural and architectural drawings and was used as a supplement to these drawings. According to the Bill of Materials obtained from On-Screen Takeoff and Athena Impact Estimator, five most significant materials of this building were recognized to be concrete 30Mpa, 5/8" Fire-Rated Type X Gypsum Board, glazing panels, galvanized studs and rebar rod, and light sections. The output from the Impact Estimator (IE) is a list of impact category during the manufacturing and construction phases to the end-of-life stage of the building. The results of the study in terms of the impact categories are as follow: •Global warming potential: 1.04E+07 kg CO₂ eq •Ozone layer depletion: 1.51E-02 kg CFC-11 eq •Acidification potential: 4.12E+06 moles of H⁺ eq •Eutrophication potential: 5.16E+03 kg N eq •Smog potential: 4.99E+04 kg NOx eq •Human health respiratory effects: 4.14E+04 kg PM2.5 eq •Weighted resource use: 5.60E+07 ecologically weighted kg •Fossil fuel use: 1.08E+08 MJ After performing Sensitivity Analysis on the five most common materials in the building and evaluating their effects on each impact category, walls show great impacts on global warming, ozone layer depletion, acidification potential, smog potential, human health respiratory effects, and fossil fuel use more than other assemblies. Also, columns and beams have the major contribution to eutrophication potential impact category since they mainly consist of concrete and rebar. Floors play the main role in impact potential of weighted resource use.
