Elon University, located in Elon, North Carolina in the Piedmont region east of Greensboro, has just over 5000 students who know to the watt how much energy they are using at any given moment. EU realized that if you want to change something, you typically will have more success if you have a method to measure your progress (like my bathroom scale and my diet). Trying to teach students and faculty how their activities and habits affect electricity and water usage is greatly enhanced when everyone has a public scoreboard to help them keep score. It also helps to keep score when you are involved in a residence hall energy conservation competition, which is another use for the Elon University Building Dashboard.
