• 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
