The University of Colorado -- which pays more than $20 million in energy bills every year -- is rewarding employees who can conserve the most energy in their buildings.
Three campus buildings have earned the rank of "Buff Energy Star" status during the 2010-11 fiscal year, as building employees have scaled back energy use by at least 5 percent over the previous year's total.
Together, the three buildings conserved more than 114,300 kilowatt hours of energy, enough electricity to power 10 homes for a year. Combined, they saved the school $12,230, according to Moe Tabrizi, campus sustainability director, and reduced carbon dioxide emissions by 193,800 pounds.
The latest Buff Energy Star winners are the Denison Arts and Sciences Building, the Koenig Alumni Center, and the Wolf Law Building.
