i Assessing Electrical Plug Loads from Office and Computing Sources at Indiana University Prepared for the Indiana University Physical Plant SPEA V600 Spring 2014 Saurabh Betawadkar, Daniel Bloom, Eric Campbell, Greg Glassley, Hannah Hunt David Sarkisian, Himadri Sinha, Emily Storm-Smith, Ryan Weiss Faculty Advisor: Dr. Diane Henshel Abstract The Indiana University Physical Plant seeks to identify areas across the Bloomington campus where energy cost savings can be attained. The purpose of this Capstone project was to identify the potential for energy-related cost savings associated with the use of computing devices and office- related plug-in devices on the IU Bloomington campus. Four areas were investigated for potential savings: plug-in devices in faculty and staff offices; Student Technology Centers (STCs); the IT-28 cyber risk mitigation policy; and Thin Client computing devices and docking stations. Additionally, an electronically distributed survey of IU faculty, staff, and students was conducted to gather information on individual behaviors and perceptions relating to these areas. Analysis of the data gathered enabled the Capstone group to provide a targeted cross-section of energy consumption on the IU campus in these areas and allowed for the development of policy recommendations for consideration by the Physical Plant. 1 Table of Contents I.
