1996 Energy Review
 Feasibility
Study Revealed
• No centralized control of occupied buildings
• Inefficient lighting
• No sub-metering to manage high energy use
• Energy waste: $60K-$80K/mo
 Solution Option: “Energy Performance Contract”
• MSU borrows funds
• Install energy improvements
• Debt service paid with generated savings
• If “guarantee” not met, contractor must pay
Energy Performance Contract” Executed
• $5.5M of energy improvements
• Scope of work:
•
15,000 Lighting retrofits
•
Variable speed drive motors
•
Electric Meters in all major buldings
•
Central Energy Management System
Central Energy Management System

Saves energy when buildings are unoccupied
• Occupied Mode

• Unoccupied Mode
• Drifts to
80 degrees (summer)
60 degrees (winter)
• Buildings systems are not shut off
