Energy Efficiency
• Using less energy to provide the same service
• Efficiency is first fuel
• Example of efficiency
3
Efficiency at the KLARC Athletic Facility
• Energy assessment at the KLARC
• Thoroughly reviewed the facility’s mechanical drawings, roster of equipment
in place, maintenance history and procedures, operating schedules
• Meter data collected to capture energy flows at key points
• Analyzed to determine the facility’s current energy input/output balance and the
specific opportunities to improve that performance (ECMs)
• Documentation of the anticipated cost/benefit performance of recommended
Improvements
