  1. Anne Duncan, Environmental Sustainability CoordinatorTerry Rowe, Sales Team Leader Getting help for large energy efficiency improvements at a small college

  2. Wartburg College FY12 • 1805 student enrollment • $49 Million Endowment • 12:1 Student Faculty Ratio • 32 buildings • 85% campus residents • Municipal Utility, Waverly Light and Power

  3. 2012 Efficiency Improvements • $2.4 Million Contract • 3486 Lighting Fixtures • Building Automation & Boiler Replacement • 1152 Water Fixtures • $270,000 Annual Guaranteed Savings • 18% decrease in GHG Emissions • (2025 goal of 20%!!)

  4. The Process • Connected by cold call • Investigate, check references • Investment Grade Audit - $150,000 • Contract for 14 ECM’s in 19 buildings • On-site supervision • Sub-contractors for execution.

  5. The Money $$$$ • Borrowed from Reserve Fund • Utility Rebates • Savings Guarantee of 15 years • (10 year payback, 15 year guarantee no brainer) • Payback Reserve Fund • After Payback invest in more energy efforts • Development of Sustainability Program

  6. This project was partially funded by a State Energy Grant from the Iowa Office of Energy Independence, which is now part of the Iowa Office of Economic Development, with funds from the American Recovery and Reinvestment Act of 2009.

  7. Why Schneider Electric? • Vast international resources • On-site management • Consistent and Ongoing Reporting an contact • Easy to work with, helped us understand • Field Experience • Grant support • Local contactors selected when able • Guaranteed Savings

  8. Terry RoweSchneider ElectricSales Team Leader

  9. The Beginning • What • Facility improvement program performed by an ESCO • How • Reallocate funds that typically pay or utilities back into infrastructure • Where • Typically in publically owned facilities: K-12, Federal, State, City • Why • Guaranteed Savings: Schneider Electric will write a check if • Guaranteed savings are not realized

  10. ESPC Process Design Engineering Looking at the buildings as systems Relationship and Accountability Long-term partner for performance ESCO designs project around long-term performance goals Energy savings and function of project are tracked long-term Expert energy managers as ongoing resource • Different than “piece meal” approach (deferred maintenance) • Provides better function and performance • Savings leveraging: Improving a building as a system allows for quick-return items to help fund needed lower-return upgrades

  11. Environmental Responsibility • Third largest user on Waverly Light and Power Grid • Reduce carbon footprint • Commitment to sustainability

  12. HOW?

  13. Determine Energy Conservation Measures • What is the science behind the measures • What is the business case

  14. What Did We Do? • Lighting Retrofits • Building Automation Systems • Water Conservation Measures • Boiler Replacement in Luther Hall • Dedicated Heat Recovery Chiller in Wellness Center

  15. HOW IS HEAT RECOVERY A RENEWABLE FORM OF ENERGY? SOLAR ENERGY BIO ENERGY THERMAL ENERGY ABSORBED FOR RECOVERY ELECTRIC ENERGY HOT WATER

  16. Fiscal Responsibility • Determine the payback • What is the Net Present Value • What is the Internal Rate of Return • How is it to be funded

  17. Funding • Used energy savings as a cash flow • Grant from the State of Iowa State Energy Program-Office of Energy Independence ($666,666) • Rebates from Waverly Light & Power • Other internal sources

  18. Results • Reduced Carbon Footprint • Reduced burden on electric grid • Job creation • Verified energy savings

  19. Reduced Carbon Footprint

  20. Other Impacts • Reduced Burden on Grid (1.7 MW) • Job Creation: 30 individuals directly worked on this project

  21. 1.5M kWh/year • 1,700 kW/year • 133,000 therm/year • 4.2M gal/year • $270,000/year
