District saves $1.7 million in utility costs
SARASOTA — Thanks to a comprehensive energy conservation program, Sarasota County Schools has saved more than $1.7 million in utility costs since June 2007, compared to the previous one-year period.
The original one-year period in 2006-07 was measured to serve as the benchmark for future comparisons so the school district can gauge its progress in future years. The $1.7-million figure represents the difference between what the district projected it would have spent on utilities for the 2007-08 year (a projection based on the benchmark year) compared to what it actually spent.
To ensure that energy is being used efficiently at schools and offices, district energy specialists perform energy audits at each site to evaluate consumption and make recommendations for changes that will result in savings.
Energy specialists evaluate the use of heating and air conditioning equipment, such as chillers, air handlers, exhausts and pumps to determine whether changes in the usage times and frequency could affect the district’s power bills. The expensive task of air conditioning 43 schools and a number of district facilities has been made less costly and more efficient by making ice at night during low-demand energy hours, then storing the ice in thermal energy storage tanks. Water is circulated over the ice during the day to create the chilled water needed for air conditioning.
The district’s custodial staff also helps identify potential savings and avoid potential loss at each site. Resources are well maintained to ensure optimum performance. Teachers and staff are coached to make sure lights are out when a room is not being used, windows and doors remain closed while air conditioning is in use, and electronic equipment is turned off each night. “Everyone plays a part in conserving energy,” said Alisha Miller, an energy manager for the school district’s Facilities Services team. “When we show people how they can help, they’re glad they can contribute to this effort to use our resources wisely.”
