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.
