GETTING HELP FOR LARGE ENERGY EFFICIENCY IMPROVEMENTS AT A SMALL COLLEGE
Anne Duncan, Environmental Sustainability CoordinatorTerry Rowe, Sales Team Leader
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
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%!!)
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.
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
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.
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

The BeginningWhat
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
ESPC ProcessDesign Engineering
Looking at the buildings as systems• 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
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
Environmental Responsibility
Third largest user on Waverly Light and Power Grid
Reduce carbon footprint

ELECTRIC ENERGY HOT WATER
HOW IS HEAT RECOVERY A RENEWABLE FORM OF
ENERGY?
Fiscal Responsibility
Determine the payback
What is the Net Present Value
What is the Internal Rate of Return
How is it to be funded
