The goal of this Capstone project was to create a mechanism for identifying buildings of irregularly high electricity use as targets for financial investment in electricity efficiency measures that would best serve the University of Pennsylvania from an economic and environmental standpoint. This mechanism was created by integrating electricity use data from Penn facilities and electricity supplier PECO into a GIS model of the Penn campus to track trends in building electricity use. The analysis of campus electricity trends was accomplished by Page | 4 creating baselines of average electricity use and comparing each building to these baselines to target outliers. Five buildings of atypically high electricity use were targeted to receive comprehensive building audits: Rosenthal, Lewis Hall, Levy Dental, Schattner Center, and the Old Chemistry Wing. A number of recommendations are also made to the University to further develop this project in the future including maintaining the currency and accuracy of the electricity use data within the GIS framework and increasing the frequency with which individual campus buildings are metered for their electricity use.
