Background: The purpose of the Energy Challenge is to instill conservation habits in participants. It rewards participants for making small behavior changes that, when performed collectively, can substantially decrease Indiana University's environmental impact.  In the summer of 2011, Nolan Hendon, Utility Conservation Intern with the Office of Sustainability, undertook a study to analyze the savings in water and electricity attributed to the Energy Challenge outside of the four-week competition window.  During just the 20 challenge weeks, academic buildings and residence halls have saved 3,813,600 gallons of water and 2,578,028 kWh of electricity.  When combined with non-challenge figures, these savings jump to 24,465,642 gallons of water and 9,438,986 kWh of electricity.  The efforts of the thousands of Energy Challenge participants have resulted in an avoidance of 9,376 metric tons of CO2 emissions and have saved the university $1,090,693 in utility costs.

Fall 2013 Energy Challenge Results | Back to Top

This fall, the challenge included 17 residence halls and apartment housing complexes; 15 lab, classroom or administrative buildings; and 13 Greek houses, making it one of the largest energy challenges in the nation. This year, the 45 buildings had savings of 1,486,224 gallons of water (enough to fill 60,000 bathtubs) and 1,522,170 kWh of electricity (the equivalent of taking 1500 average homes off line during the competition) compared to their normal usage. Each building competed to reduce the largest percentage of water and electricity usage in comparison to each building’s weatherized baseline calculation.

Academic buildings were placed in three categories based on building type: administrative, classroom, or laboratory buildings. Residential Programs and Services’ (RPS) residence halls and apartment housing were placed in four categories based on location: northwest, northeast, central, and southeast neighborhoods. Thirteen housed sorority and fraternity houses competed in a final category, making eight total for the competition. This year's first place winners are as follows:
