A little bit means a lot.
* Insulated thermapane replacement windows replaced the old wooden ones that leaked 10 times more air.
* High-pressure sodium lamps have supplanted incandescent bulbs and use only 30 percent of the energy.
* Campus air-conditioning chillers are now cooled with readily available groundwater, a unique process that reduces fuel bills by 20 percent.
* The National High Magnetic Field Laboratory rescheduled experiments with some of the world's most powerful magnets to lower power consumption during peak usage periods.
* Hundreds of lights at the school's Doak Campbell Stadium have been dark at least 12 hours a day. Even the blue-light security system scattered liberally across campus now boasts cheaper-burning bulbs that reduce their energy demands by as much as 80 percent.
* Hundreds of labs in typically fuel-hungry science and College of Medicine facilities are scheduled to receive the latest in low-flow fume hoods, which use half the air of older models.
When FSU launched its energy savings program with Johnson Controls in 1997, the company promised the changes would reduce utility bills by $8.5 million within a decade. But by 2005, the calculators showed that the university was $2 million ahead of the original ambitious schedule. The latest round--occupancy sensors in empty classrooms to turn off lights and idle computer monitors, coupled with new technology lighting and campus steam retrofits--should add yet another $1 million to the savings chest.
Best of all, Florida State's success is far from a fluke. Take a look at how other universities are finding that small changes can make a big impact.
Action or Product: Analysis reports
Institution: Oklahoma City University
Provider: Honeywell (www.honeywell.com)
These ongoing reports examine energy cost and consumption patterns on campus, A 2004 report showed' administrators certain thermostat areas where usage was too liberal, so they added more thermostat controls for improved efficiency. The analysis also prompted OCU's decision to take over responsibility of its own transformers, which led' to a 30 percent reduction in energy costs.
Action or Product: CHP systems
Institution: Colby College (Maine)
Provider: EcoGeneration (www.cogeneration.net/EcoGeneration.htm)

With 10 electric vehicles, that's a total of $325,000 across the fleet's expected lifetime. This doesn'ttake the lower sticker price into account: The current electric pickup trucks cost $8,000 each compared to their $14,500 gas-drinking buddies.
Action or Product: Electric substation
Institution: Baylor University (Texas)
Provider: Local energy provider
This type of facility allows a campus to purchase electricity directly from an energy provider. Baylor reports an electric savings of $600,000 annually--and because this route reduces costs by 1 cent per kilowatt hour, future energy measures are poised to save still more.
Action or Product: Energy Savings Performance Contract
Institution: Eastern Illinois University
Provider: Honeywell (www.honeywell.com)
Through this program, a school can overhaul its aging utility system at no upfront capital costs; retrofits are paid for by the energy savings guaranteed by the contract. In 2004, the Illinois Department of Commerce and Economic Opportunity cited user EIU in a report as having the lowest energy cost per square foot among all public universities in that state. (In a similar program with Chevron Energy Solutions, Saint Mary's College of California's retrofit will save it $250,000 per year in lower utility, bills.)
Action or Product: Geothermal HVAC
Institution: Maharishi University of Management (Iowa)
Provider: Enviroteg (www.geothermalheatpump.com)
This technology uses a constant 55-degree liquid to either cool the air in the summer or warm up frigid air before adding conventional- heating methods in winter. MUM officials knew this would be more costly to initially install but anticipate a savings when played out over a 20-year life cycle.
Action or Product: High-efficiency washers
Institution: American University (D.C.)
Provider. Maytag (www.maytag.com)
The 278 energy-efficient laundry room washers instaned ,t Au hold 32 percent more clothes than the old machines. This saves 18 gallons of water per load or 2 million gallons per year--enough water to fulfill the drinking needs of the AU community for two years.
Action or Product: HVAC controls
Institution: The University of Maine
Provider: Honeywell (www.honeywell.com
These controls allow managers to monitor dorm room temperatures, adjust temperatures from a computer screen, and track trends. At UMaine, the new system has dramatically cut down on service calls to the dormitory. Managers estimated they had received between 10 and 20 service calls a semester; spring 2005 saw only two calls. Utility bills also have decreased, and the results have led officials to try to have the dorm recognized as a green building.
Action or Product: Light harvesting
Institution: The University of North Carolina at Charlotte
Provider: Venture Lighting (www.ventureli htin .coin)
This process automatically dims the overhead lights as the ambient natural light increases. UNC at Charlotte measured a 50 percent reduction in lighting energy used at its Atkins Library.
Action or Product: Low-e fabric ceiling
Institution: University of Massachusetts, Amherst
