“We’re saving operating costs on all

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
