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

Energy Management 101 The Building 20 -Story Office Building: • 200, 000 ft 2 • 5 years old, no energy conservation • Complex, energy intensive HVAC systems • High utility bills • No building automation system 11

Energy Management 101 How 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

Energy Management 101 How 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

Benchmarking Using ENERGY STAR www. energystar. gov/benchmark 15

Comparative Metrics: The Heart of Benchmarking Is 60 MPG high or low for this automobile? Fuel Efficiency: MPG Is 90 k. Btu/SF/YR high or low for this building? Energy Performance Rating: 1 to 100 16

ENERGY STAR Score Eligible Building Types Banks/Financial Institutions Courthouses Data Centers Houses of Worship K-12 Schools Retail Stores Senior Care Facility Dormitories Medical Offices Supermarkets Hospitals Hotels Multifamily Housing Office Buildings Warehouses 17 Wastewater Treatment Plants

Two Types of Action • Smarter use of what you have right now (Discretionary Operation) • Energy Audits and Capital Improvements 20

Disincentives for the Building Engineer • Risk of occupant discomfort • Risk of equipment failure • Experimentation can be terrifying 22

Incentives for the Building Engineer • Regular monitoring by the manager • Managerial encouragement to experiment • Occasional, brief discomfort is OK • Teamwork • Accomplishment – Getting results 23
