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

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

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

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

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

Energy Management Guidelines Connections: EnergyStar ASHRAE Standard ASHRAE 2011 Handbook, Chapter 36 Practical Experience Opportunities in your buildings

Where are you at?

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

Establishing historical daily meter reading

Daily electric read

Daily Temperature Reading NOAA Weather underground

Daily Temperature Reading  NOAA  Weather underground

Best Fit equation - Electrical

Best Fit equation – Natural Gas typical

Daily Report – on site

Monthly report and review - system

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

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

#1 Continuous steam trap audits and repairs to failed traps

#2 Chilled water pump speed reset and changed controls

#3 Reduced steam pressure on boilers

#4 Chilled water reset on chillers

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

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

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

#8 Night setback on VAV boxes throughout building by area

#9 Programmed an outside air reset for our steam heat exchangers for VAV reheat

#10 Found chilled water coils piped backwards on air handling units

Aurora Health Care Utility Summary Savings: 14.8% reduction in energy usage
