The Alachua County Library Headquarters in Gainesville, Florida is using its IceBank® energy storage tanks to reduce operating costs and save taxpayer money. CALMAC’s technology enables the 80,000 square foot library, which was built in 1992, to shift cooling load so that it uses nighttime energy that is 68 percent cheaper than the energy that would be used for creating instantaneous cooling during daytime hours. Additionally, thermal storage allows monthly demand (kW), and the resulting demand charges, to be cut in half. This is significant since 40 percent of the headquarters’ total electric costs for the year can be directly attributed to cooling the structure and the facility’s power provider implements a demand charge that equates to roughly $9.25 in extra fees per kW during peak demand hours.
