Santa Fe’s Gymnasium usage ranges from a few students playing basketball to events such as graduation where nearly 3000 people are in attendance. The challenge was to design a system that could provide comfort for such a drastically varying load and be energy efficient at the same time.
This challenge was overcome with an air handling system that can vary its air flow to one eight of its capacity. Even at lower air flows, the air distribution is such that space comfort is maintained uniformly. The energy model for the new system showed over 40% reduction in energy consumption.
Summary:
As the existing cooling towers reached their useful life SF saw an opportunity to replace them with new, more energy efficient cooling towers. After their installation the new cooling towers have had a significant impact on lowering energy consumption on campus. General Facts: Original Construction: 1980Project Description: Replaced existing cooling towers with new energy efficient cooling towers. Technical Facts: Saved electricity: 614,000 kWh, enough electricity to power 63 homes for a year. 

Summary:
This project replaced the existing lights in the gymnasium with new, high efficiency T5 light fixtures. General Facts: Light fixtures with T5 bulbs are more efficient than traditional fixtures with T8 and T10 bulbs.Technical Facts: The existing lights in the gym produced 18 to 24 foot candle of light and consumed 27.1 kw of energy. The new T5 fixtures produce 40 to 60 foot candles of light per fixture while consuming 8.9 kw of energy, producing twice the light for one third of the energy used by the old fixtures. 

Summary:
Many air handling units at SFC have been replaced at the end of their lifespans. Here is an example of the savings from just one replacement with smart energy designs. Building B houses SFC’s math program and has predominantly classroom space. It had multizone type air handers that had lived past their expected life. SFC took the opportunity to replace them and installed an energy efficient variable air volume system. Digital controls were added that allowed for even more energy conservation strategies to be executed. General Facts: Saved electricity: 118,000 kWh, enough to power 10 homes.Emissions reduced: 100 tons of CO2, equal to taking 17 cars off the road for a year. Carbon reduction: Equal to carbon sequestered by 20 acres of pine forest each year. Qualified for Gainesville Regional Utility rebate of $40,000 for the 2008 year. Technical Facts: Original Construction: 1970 
Parking Lot Lights:
SFC replaced 216 metal halide lamps using 325 watts each with induction lamps using 200 watts each for a reduction in power use of 43.2 kW. Campus Walkways: SFC replaced 37 lamps using 175 watts each, 20 lamps using 100 watts each and 3 lamps using 400 watts each with LED lamps using 40 watts each for a total reduction in power use of 7.3 kW.Miscellaneous Areas: SFC replaced 16 lamps using 400 watts each with 200 watt induction lamps, 3 lamps using 400 watts each with 22 watt LED, 7 lamps using 100 watts each and 3 lamps using 175 watts each with a combination of 3 lamps using 80 watts and 4 lamps using 40 watts each for a total reduction in power use of 5.2 kW.
