Goal and Scope

Project Conduct Life Cycle Assessments of 13 buildings at UBC Residences and Faculty Buildings Total of 25% of floor space at UBC

Outputs Create a materials inventory for each building or complex Estimate environmental impacts

Outcomes Generate baseline data on estimated environmental impacts Use baseline as a reference for future performance upgrades Outline approach for conducting an LCA

Intended Audience UBC Policy Makers Use study to help create effective policies and frameworks Others Interested in LCA –Developers –Architects –Engineers –Municipalities –Institutions Use study as a model for how to conduct an LCA

Scope Physical –Structural –Envelope –Operating energy Temporal –“cradle to gate” assessment Assessments are on a per square foot basis

Tools OnCenter OnScreen TakeOff v Athena Environmental Impact Estimatorv

Impact Assessment EIE compiles an inventory of inputs and outputs for each stage of building life based on takeoff data and database references Uses US EPA Tool for the Reduction and Assessment of Chemical and other environmental Impacts (TRACI) v 2.2

Summary Measures  Global warming potential  Acidification potential  Eutrophication potential  Ozone depletion potential  Photochemical smog potential  Human health respiratory effects potential  Weighted raw resource use  Primary energy consumption

Further Analysis Sensitivity –Understand how changes in material volumes affects changes in overall impacts Energy Modeling –Model building energy losses through exterior –Investigate how envelope upgrades could reduce energy loss
