Frequently Asked Questions

What is a baseline?
A building’s usage baseline is an average of electricity and water usage during a four-week period (October 5th to November 2nd) over the past three years (2008-2010).  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.  Buildings compete against this baseline (their past usage) in the Energy Challenge.

How can I promote conservation and the Energy Challenge in my residence hall/academic building/Greek house?
Please contact for promotional materials and/or programming ideas.  We have magnets, stickers and fliers, and we would be happy to come speak at an event.
