  1. Energy Management for Dummies Reduced Emissions Positive Cash Flow A Sustainable Activity Dick Pearson, P.E., ASHRAE Fellow

  2. Renewables as anEnvironmental Solution?

  3. Where Do We Use Energy?

  4. Energy Management is the Quickest, Cheapest, Cleanest Way to Extend World Energy Supplies Energy management can provide 2.5 times the environmental impact of renewable energy

  5. Global CO2 Levels Exceed 400 ppm

  6. Energy Management 101 – Example • Management commitment • Manual daily meter reading • Operational changes only 10

  7. Energy Management 101The Building 20-Story Office Building: • 200,000 ft2 • 5 years old, no energy conservation • Complex, energy intensive HVAC systems • High utility bills • No building automation system 11

  8. Energy Management 101How It Worked Actions by Facility Manager: • Reviewed operations ideas with building engineer and design engineer • Reviewed daily meter data for impact, intuitively adjusting for weather • Harassed/complimented building engineer daily on performance 12

  9. Energy Management 101How It Worked • Actions by Building Engineer • Aligned building schedules with occupancy times • Raised cold deck temperature • Lowered hot deck temperature • Outside air was introduced only during occupied hours • Reduced duct pressures Savings in one year: 33%! 13

  10. The Management Content of Energy Management www.energystar.gov ENERGY STAR Guidelines describe a management cycle that helps you with Execution—getting things done! 14

  11. Benchmarking Using ENERGY STARwww.energystar.gov/benchmark 15

  12. Comparative Metrics: The Heart of Benchmarking Is 60 MPG high or low for this automobile? Is 90 kBtu/SF/YR high or low for this building? Fuel Efficiency: MPG Energy Performance Rating: 1 to 100

  13. Houses of Worship K-12 Schools Office Buildings Banks/Financial Institutions Dormitories Medical Offices Hospitals Retail Stores Warehouses Hotels Wastewater Treatment Plants Data Centers Supermarkets Courthouses ENERGY STAR Score Eligible Building Types Multifamily Housing Senior Care Facility

  14. Energy Star Portfolio Manager

  15. Two Types of Action • Smarter use of what you have right now (Discretionary Operation) • Energy Audits and Capital Improvements

  16. Disincentives for the Building Engineer • Risk of occupant discomfort • Risk of equipment failure • Experimentation can be terrifying

  17. Incentives for the Building Engineer • Regular monitoring by the manager • Managerial encouragement to experiment • Occasional, brief discomfort is OK • Teamwork • Accomplishment – Getting results

  18. Examples of Success

  19. Greener Pastures with Energy Savings Emissions Reduction at Madison Area Technical College Source: Madison College Engineering Manager – Wesley Marquardt – wmarquardt@madisoncollege.edu For 50 state emissions data online calculator, refer to Leonardo Academy: http://www.cleanerandgreener.org/resources/pollutioncalculator.html 25

  20. City of Madison Buildings • Reductions 2009-2012 • Energy: • 17.1% Reduction • 26,527,171 kBtu/yr • 17 kBtu/ft2-yr • GHG Emissions: • 3,371 MT/yr • Cost Savings: • $309,376/yr

  21. Downtown ChicagoEnergy Star Building

  22. Aurora Healthcare Success • Reductions 2009-2012* • 8 million ft2 • Energy: • 14.8% Reduction • 351,716,161 kBtu/yr • 45.4 kBtu/ft2-yr • CO2 Emissions: • 64,669 MT/yr • Cost Savings: • $2,166,250/yr • Minimal Capital Expenditures • *Two Hospitals & One Clinic Achieve EnergyStar Award 28

  24. Aurora Health Care Equivalent Revenue Using a 4% margin • 2009 – 2012 Total Energy Savings (weather-normalized) • Total Savings = $8,665,000 • $8,665,000 ÷ 0.04 (margin) = • $216,625,000 equivalent revenue • $216,625,000 ÷ 4 years = • $54,156,250 equivalent revenue per year

  25. Energy Management is the Quickest, Cheapest, Cleanest Way to Extend World Energy Supplies Energy management can provide 2.5X the environmental impact of renewable energy

  26. Remember to Monitor!!
