the buildings under this project. Our
occupants are happier, safer, and we
have more control of our costs.”
-David Mosby, Missouri State Facilities Director
Scaling Up - Case Study: State of Missouri
Sustainability Command Center
15% reduction in energy and operational
costs for over 1000 state-operated facilities

• Georgia Tech buys electricity on dynamic
hourly price from Georgia Power
• Each hour, building management system
reads prices for for next 48 hours from
utility’s web service feed
• Facilities director sets price threshold for
automated load shedding mode
Observing a ~1MW peak load reduction, 7% of load for participating buildings
Savings during initial summer 2006 single building pilot

RESULTS 38% energy savings, guaranteed
Simple payback under 3 years
Anticipate LEED Gold certification
Energy Star Top 10% of U.S. office buildings
33% reduction in cooling load
Savings of $4.4 million annually
• More than 50% the energy savings exist within tenant spaces – can’t ignore them!
• Sub-metering and web application provides tenants with energy information, feedback, analysis, and tips
• Allows new lease structures to align tenant and landlord incentives
