Indiana University Bloomington


Official Rules

Each building competes against a usage baseline, an average of electricity and water usage for their building. Electricity usage carries twice the composite weight of water usage.  The combined water (33%) and electricity (66%) usage makes up the composite usage for each building.

Weekly, our utilities team records both the water and electricity usage of each building.  These recordings are compared to the buildings’ baselines.  The buildings that reduce their water and electricity usage by the highest percentage are crowned as winners of the Energy Challenge.


-Participants take pictures of themselves taking part in certain sustainable activities fall under the four categories of Electricity, Water, General Sustainability, and Creativity (outlined below).

-Players then either post the pictures to the IU Energy Challenge Facebook page or tweet them to the IU Energy Challenge (@HoosierEC) with their name, residence center (or Greek chapter), and #iuenergychallenge.

-Students receive one point for each picture posted and can redeem points earned for gift cards (a list of options can be seen below). A representative for each residence center or Greek chapter will be notified every week of participants' point accumulations. In addition, players can email if they have questions regarding points.

-After the end of the Energy Challenge, students email us at with their name, residence or Greek chapter, and gift card selection. Gift cards will be mailed to students via Campus Mail.
