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

6. Global CO2 Levels Exceed 400 ppm

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

8. 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

9. 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

10. 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

11. 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

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

13. 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

14. 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

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

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

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