Real Savings…

Restrict Thermostat Setpoint Range on Trane Tracer System:

• heat no higher than 71 degrees• cool no lower than 73 degrees

Modified Cutler Hammer Lighting Control Schedule:• manual on switch in mornings• classroom sweeps at evening intervals

…Reduction in kwh/therms up to 10%

Real Savings…

Water Electric instantaneous heaters Aerators on hand wash sinks

Electricity/Gas “Just In Time” Operations (ovens, hot wells, warming

cabinets) HVAC Close F/C doors during deliveries Vacuum coils on condenser units Add frequency drives on AHU’s

Strategy#1:BehavioralModificationsStrategy#1:BehavioralModificationsBestPracticesinFoodService

Real Savings…

73,214,882 Copies Made in ‘08/’09

Established Copy Limits in ‘09/’10

Goal: 20% Volume Reduction (14,500,000)

Actual Reduction: 19,000,000

…$190,000 Savings in One Year!

Strategy#1:BehavioralModificationsStrategy#1:BehavioralModificationsReducePrintingWaste

Temperature Controls at Wood View ES:

1. Rezone building to separate interior and exterior spaces

2. Wrote program to monitor average and extreme temperatures at perimeter

3. Wrote program to allow override control of outside air dampers

4. Wrote program to allow override of classroom cooling dampers

Real Savings…

Fan energy dropped by nearly 70%, representing $250 per week savings, per school!

Strategy#2:BuildingSystemOptimizationStrategy#2:BuildingSystemOptimizationRezoneBuildingTemperatureControls

Real Savings…

Re‐evaluated recycling dumpster pick‐up at schools Went from 2 pick‐ups/week with 6 yard dumpster to 1 pick‐up/week with an 8 yard dumpster

Annual savings of $3,900 for our elementary schools

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesRecyclingPick‐upsatSchools

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesRecyclingPilotProgram:Plastics,Metal&Paper

Identify and Educate Staff/Students of Opportunity

Goal for Each Cafeteria and Kitchen:from 7 bags of trash dailyto 5 bags of trash and 2 bags of recycling daily

2 bags diverted dailyX 100 school days (175 days/school year)X 12 elementary schools

2,400 bags diverted from landfill each year!

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesRecyclingProgram:ScrapMaterial

Initiated by Grounds Department…

• Collect scrap material from district projects

• Normally would end up in landfill

• Transport material to recycling yards

…Collect approx. $25,000 annually in scrap payments.

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesRecyclingPilotProgram:Styrofoam

Styrofoam (polystyrene) Recycling:

Over 1 million Styrofoam Lunch Trays Used Annually

Establish Lunch Room Program in Each School to Clean and Stack Trays

Transport Bagged Trays to Recycling Center

Goal is to further reduce trash quantity and increase recycling amount

…Over 20,000 trays a week diverted from landfill.

Real Savings… Jane Addams Site Improvement

Project Obtained Soils Free of Charge

from Metropolitan Water Reclamation District

Used as Amendment to Topsoil Improves Soil Quality

Adds Organics No Weeds Reduces Long Term Soil

…saved $12,000 on new soccer field (40 semi‐loads @ $300/load)

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesBioSoilsonGroundsWork

Strategy#3:EnvironmentalStrategiesStrategy#3:EnvironmentalStrategiesGreenCleaningProgram

All Schools Comply with Illinois Green Cleaning Act

District Initiative is to EXCEED Standards-built into our cleaning specifications

•Additional green cleaning products (hand soap, green seal certified products)

•Microfiber dust pads and clothes in lieu of terry cloth and paper towels

•Use of water based scrubbers (no chemicals)

Strategy#4:EnergyStrategiesStrategy#4:EnergyStrategiesCondensateRecoverySystem

Real Savings (Bolingbrook High School)Condensation from main AHU’s collected in a tank and used as make‐up water for cooling towers.

• Estimated to save 257,000 gallons of water/year.

• Approximately 7% of total water used for cooling system.

Real Savings…

From Summer of 2007 through today:

Over 30 Variable Frequency Drives installed on AHU’s, RTU’s, Fans, Chiller/Boiler Pumps

2 “Fan Walls” installed for AHU’s

Multiple new efficient Chiller/Boiler Pumps

Used in house labor for all installations

Strategy#5:CapitalImprovementsStrategy#5:CapitalImprovementsPumps,FansandVariableFrequencyDrives

Real Savings…

HVAC Project at BJ Ward ES Replaced 4 large fans in main air handling unit in August ‘08

New modular fan system installed with variable speed capability

232,189 annual kw savings @ .10/kw = $23,2191,500,000 total kw savings to date @ .085/kw = $128,000

Initial investment $82,000, DCEO rebates $10,000

Strategy#5:CapitalImprovementsStrategy#5:CapitalImprovementsEquipmentReplacement


Chiller Replacement Project at RHS:

Evaluated a Standard 300 Ton Chiller vs. 200 Ton with Ice Storage Capacity

ROI investment Analysis Favored Ice Storage System

Installation April 2011 Anticipated benefits:

• lower energy costs• reduce peak hour demand• operate smaller tonnage unit• quieter operation• flexibility


Boiler Replacement Project at RHS:

Replaced 5 boilers with 4 high efficiency condensing type boilers with variable flow

ROI Analysis Favored Condensing Boilers over Flex Water Tube Boilers

Installation Summer 2012 Anticipated Benefits:

• Reduce fuel usage by 20%• Separate domestic HW from heating

plant• Reduction in electrical usage (VFD’s)• Estimate $30,000 annual savings

Strategy#5:CapitalImprovementsStrategy#5:CapitalImprovementsFixtureReplacement
