You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS
4th Consecutive Year – School Division Reduced Utility Costs….
Energy Reduction Efforts 2010
While the average cost of electricity decreased 14% from $.091 to an average cost of $.079 per KWH for all usage
How Did We Do It?
Energy Reduction Efforts 2010
-Energy Performance Contracts
-Temperature Control Reductions
-Retro Commissioning

Energy Reduction Efforts 2010
History◦ Recognized opportunity to reduce energy consumption by
modernization of facility building systems through Energy Conservation Measures (ECMs)LightingOccupancy SensorsMotors & Fan DrivesWater Conservation
◦ Utilized State Energy Performance Contract Program to
evaluate, interview and select an energy performance contractor
◦ Contracts are funded through annual energy savings
Energy Performance Contract
History◦ Selected NORESCO for Phase I - 2006
◦ 18 Schools◦ 7 Energy Conservation Measures◦ Completed April 2007
◦ Selected NORESCO for Phase II - January 2010
◦ 8 Schools◦ 4 Energy Conservation Measures◦ Estimated Completion October 2011
Energy Performance Contract
Phase II – Update
◦ In June 2010 NORESCO initiated Detailed Energy Audit
◦ Survey of 8 school division facilities: Hampton Oaks ES , Park Ridge ES, Winding Creek ES, Drew
MS, AG Wright MS, Brook Point HS, Mountain View HS, and the Professional Development Center
◦ Four (4) energy conservation measures (ECM’s) ◦ Audit Completion – November 24, 2010◦ Approval process Completed - January 14, 2011◦ Estimate Start Work – June 9, 2011◦ Estimate Completion of Work- October 30, 2011
Energy Performance Contract
Energy Conservation Measures Selected
◦ ECM #1 - Efficient Lighting ◦ ECM #2 - Occupancy Sensors in classrooms,
hallways, offices, gyms)◦ ECM #3 - Water Conservation (low flush)◦ ECM #4 - Variable Fan Drives & Efficient Motors
for HVAC Equipment Estimated Annual Energy Cost Savings =
$199,500.00 per year Guaranteed
