1. Energy Program Implementation Reducing Operational Expense by Benchmarking and Continuous Improvement Practices

2. Presentation Objectives Initial steps taken for energy management implementation Benchmarking development Cost benefit analysis for energy conservation projects as a case study Benefits and results

3. Aurora Health Care Private not for profit integrated health care provider serving eastern Wisconsin 15 Hospitals Over 200 clinics and other real estate 70 Pharmacies 14,800,000 sq. ft. of managed space $58M utility spend

4. Our purpose:  We help people live well. Our values:  Every patient deserves the best care  Responsibly managing resources  Building a healthy workplace through accountability, teamwork and respect

5. Where We Started in 2008 A collection of hospitals with separate utility budgets. Facility managers reporting to local hospital administrators Volatile energy costs System energy intensity benchmarks at 229 kBtu/sq ft

6. Energy Management Guidelines Connections: EnergyStar ASHRAE Standard 100-2006 ASHRAE 2011 Handbook, Chapter 36 Practical Experience Opportunities in your buildings

7. Where are you at?

8. Establish Baselines Use historic data Usage vs. average temperature Model a best fit line for prediction Input of daily temp = output of expected energy use Use statistical tools to react

9. Establishing historical daily meter reading

10. Daily electric read

11. Daily Temperature Reading NOAA www.noaa.gov Weather underground www.wunderground.com

12. Daily Temperature Reading  NOAA  Weather underground

13. Best Fit equation - Electrical

14. Best Fit equation – Natural Gas typical

15. Daily Report – on site

16. Monthly report and review - system

17. Best Practices and Knowledge Sharing Monthly Facility Energy Team Meeting. Share Best Practices – Facility Manager presents topic Track implementation at each site Develop knowledge sharing document(who, what, how much, how to) Energy tours by Facility Managers

18. Energy project review prioritization Idea generation Measure monitor Estimate savings Estimate costs Establish available grants Evaluate implementation feasibility Pareto

23. Aurora Medical Center Oshkosh (AMCO) Energy Reduction Projects Energy Reduction from the AMCO Facilities Department that were implemented to reduce energy costs

24. #1 Continuous steam trap audits and repairs to failed traps

25. #2 Chilled water pump speed reset and changed controls

26. #3 Reduced steam pressure on boilers

27. #4 Chilled water reset on chillers

28. #5 Started to monitor electricity- actual usage and daily usage

29. #6 Do rounds to shut lights off & are vigilant about wasted energy usage

30. #7 Relocated building pressure sensors & changed building pressure program control on building automation system

31. #8 Night setback on VAV boxes throughout building by area
