LIGHTING THE ACADEMIC COMMONS: A Case Study of Electricity Efficiency of Incandescent, Compact Fluorescent and LED Lamps at Clark University

December 15, 2012


This project explored the efficiency of the lighting system at the Academic Commons (AC) at the Goddard Library at Clark University as part of an academic research paper for the Technology for Renewable Energy course taught by Dr. Charles Agosta, Chair of the Physics Department. The study builds on students' responses to informal and open-ended surveys and electricity energy consumption data from the lighting systems. The data were analyzed using MS Excel 2010 by conducting descriptive statistics on demographic characteristics and statistical analysis of electricity used via lighting to determine energy cost, savings, CO2 emissions, and offsets by comparing the status quo against two hypothetical scenarios. The results indicate that, while the status quo (CFL light bulbs) electricity consumption seems efficient in terms of CO2 emissions and cost compared to incandescent light bulbs, converting the lighting systems to LEDs would reduce CO2 emissions substan…
