The county library in downtown Gainesville, Fla., is replacing its existing 195-ton chiller with a high-efficiency 130-ton chiller and five thermal energy storage tanks. The tanks will be used to collect and freeze water during off-peak hours, when electricity is cheaper. The ice will then be used to chill the building's air-conditioning system during the day. The CALMAC system is projected to save the county about $40,000 a year in energy costs.
