APPLIANCES/LIGHTING: DUC, SEIGLE, AND THE DANFORTH CAMPUS Lindsay Aronson, Jacob Cohen, Will Fischer, Matt Mitchel, Alan Pinkert EECE 449, Spring 2010

Project Objectives  We aimed to :  Examine lighting and appliances in the DUC, Seigle Hall, and on the Danforth Campus  Look at energy consumption by appliance and by space  Show trends and suggest improvements to reduce the carbon footprint of Washington University

Approach and Methodology  Started by identifying how to breakdown spaces within each given area  Researched appliances found in the different kind of spaces identified and determined their wattage  Determined hours of use for appliances/lighting  To confirm, took metered energy data, subtracted HVAC consumption, and compared calculations

Further Approach and Methodology: Danforth Campus  Obtained space breakdown data from the Department of Space Utilization  Eliminated and grouped together specific spaces

Electricity Breakdown: Danforth Campus Final Analysis: 23,000,000 kWh/y consumed on Danforth Campus. Compared to previous observed value of 68,500,000 kWh/y. (33.5% accounted for)

Energy Breakdown: Seigle

Results for DUC Food Service

Summary and Conclusions  Circulation area is the largest energy consumer  Recommend installing motion sensor lights  Computers are another major energy drain  Stand-by should be used during the day, but at night computers should be shut down completely  Other recommendations:  Install motion sensors in bathrooms and classrooms  Use “Night mode” lighting setting in hallways without motion at night  Schedule night classes and meetings on first and second floors so that other floors’ lights can be turned off
