CEEMI Strategies:

Creating Sustainability in Our Schools

Comprehensive Energy and Environmental Management Initiative

Strategy #1: Behavioral Modifications

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: Behavioral ModificationsBest Practices in Food Service

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: Behavioral ModificationsReduce Printing Waste

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: Building System OptimizationRezone Building Temperature Controls

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 #2: Building System OptimizationPumps, Fans and Variable Frequency Drives

Building Automation System (BAS):

Utilize Trane Tracer Software as Platform

Migrating to Trane’s ES Web Based System

Allows Universal Monitoring and Response to Temperature Control in the District

Future Goal is to Incorporate ‘Dashboard’ Capability

Strategy #2: Building System OptimizationUtilize Technology

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: Environmental StrategiesRecycling Pick-ups at Schools

Strategy #3: Environmental StrategiesRecycling Pilot Program: Plastics, Metal & Paper

Identify and Educate Staff/Students of Opportunity

Goal for Each Cafeteria and Kitchen:

from 7 bags of trash daily

to 5 bags of trash and 2 bags of recycling daily

2 bags diverted daily

X 100 school days (175 days/school year)

X 12 elementary schools

2,400 bags diverted from landfill each year!

Strategy #3: Environmental StrategiesRecycling Program: Scrap Material

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: Environmental StrategiesRecycling Pilot Program: 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

Maintenance

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

Strategy #3: Environmental StrategiesBio Soils on Grounds Work

Strategy #3: Environmental StrategiesGreen Cleaning Program

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: Energy StrategiesCondensate Recovery System

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.
