9 Creating Sustainability in Our Schools Why CEEMI? (Internal Benefits) Contributes to High Performance Learning Environments Organizes Resources / Ideas Pro active vs. Re active Facilitates Budgeting Provides Baselines Allows Measurement & Verification Demonstrates Leadership Comprehensive Energy and Environmental Management Initiative

10 Creating Sustainability in Our Schools Why CEEMI? (Global) Manage Limited Resources and Budgets Act Socially Responsible Teach Environmental Stewardship to Our School District and Community.We all practice this to varying degrees Comprehensive Energy and Environmental Management Initiative

11 Creating Sustainability in Our Schools CEEMI Strategies: 1. Behavioral Modifications 2. Building System Optimization 3. Environmental Strategies 4. Energy Strategies 5. Capital Improvements 6. Building Certification 7. Educational Integration Comprehensive Energy and Environmental Management Initiative

12 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%

13 Strategy #1: Behavioral Modifications Best Practices in Food Service 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

14 Strategy #1: Behavioral Modifications Reduce Printing Waste 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!

15 Strategy #2: Building System Optimization Rezone Building Temperature Controls Real Savings 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 Fan energy dropped by nearly 70%, representing $250 per week savings, per school!

16 Strategy #3: Environmental Strategies Recycling Pick ups at Schools 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

17 Strategy #3: Environmental Strategies Recycling 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!

18 Strategy #3: Environmental Strategies Recycling 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.

19 Strategy #3: Environmental Strategies Recycling 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.

20 Strategy #3: Environmental Strategies Bio Soils on Grounds Work 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 $300/load)

21 Strategy #3: Environmental Strategies Green Cleaning Program All Schools Comply with Illinois Green Cleaning Act District Initiative is to EXCEED Standardsbuilt 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)

22 Strategy #4: Energy Strategies Condensate 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.

23 Strategy #5: Capital Improvements Pumps, Fans and Variable Frequency Drives 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

24 Strategy #5: Capital Improvements Equipment Replacement 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 = $23,219 1,500,000 total kw savings to = $128,000 Initial investment $82,000, DCEO rebates $10,000

25 Strategy #5: Capital Improvements Equipment Replacement 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

26 Strategy #5: Capital Improvements Equipment Replacement 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

27 Strategy #5: Capital Improvements Fixture Replacement LED Lighting Replacement Projects at BHS & RHS: Replaced Metal Halide with L.E.D. Light Fixtures in Fieldhouses and Gyms L.E.D. fixtures more energy efficient than Metal Halide Installation Summer 2014 Anticipated Benefits: Complete light level flexibility Reduced maintenance costs Reduction in electrical usage Anticipate $51,700 annual savings

28 Strategy #6: Building Certification LEED Certification Real Savings Our green school performs positively but room for improvement, currently 58.5 Energy Use Intensity (EUI)!

29 Strategy #6: Building Certification Governor s Illinois Sustainable Schools Compact Commitment of Individual Schools to Sustainable Practices: Conserve Energy and Lower Carbon Emissions Encourage Recycling and Purchase Products with Minimal Packaging Conserve Water for Landscaping Plant Drought Resistant Native Species in Landscaping Areas

30 Strategy #7: Educational Integration Showcase School Programs The Ecology Club at Martinez Middle School Students Interested in Environmental Issues Students Sponsor Various Projects Recycled Art Fair Earth Day Celebration Team with Community in American Recycle Day Partner with Grounds Department in Landscape Project

31 Strategy #7: Educational Integration Showcase School Programs Edible Vegetable Garden Grant Program Sponsored by Food Nutrition Service Dept. 9 School Gardens in the District by this summer Promote value of gardening with nutritious meals Involve students, staff and community

32 Strategy #7: Educational Integration Showcase School Programs 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
