As part of ongoing efforts to reduce its $25 million-a-year energy bill, the University of Colorado at Boulder is rewarding staff members who implement money-saving strategies in campus buildings. By following five specific program recommendations, winners of the Buff Energy Star Award for fiscal year 2005-2006 helped reduce energy use in three buildings by 5 percent compared to the prior 12 months, paring campus energy costs by more than $90,000. For their efforts, each will receive a one-time $1,000 bonus.
