College House Competition

The Power Down Challenge is a month-long energy reduction competition among College House and Sansom Place residents hosted by Penn's Green Campus Partnership.  Students in each residence participate to see which building can reduce its energy use the most and compete for prizes.

The 2015 Competition

Each year, Penn's residences compete to see which building can achieve the great energy reduction and contribute to the University's Climate Action Plan goals to reduce the campus's carbon footprint.  Before the start of the Power Down Challenge, each house’s average energy use is calculated as a part of a unique baseline reading, which is used as a basis for comparison during the competition.  Because the Quad is metered as one building, Fisher Hassenfeld, Ware, and Riepe collaborate together as a single building.
Electricity is measured in kilowatt-hours to determine the competition winner.
The competition is based on two different measurements:  (1) % reduction in average electricity use and (2) total gross electricity reduction.  The winning building for each category will receive various prizes, which are yet to be announced.
