by AF0310 c5 — March 15, 2010—CALMAC, a leader in energy storage systems, has installed 16 CALMAC IceBank energy storage tanks for the new “EEE” High School campus in Weeki Wachi, Florida, and its neighboring K-8 campus.
Matern Professional Engineering designed the high school HVAC system to help qualify the facility to meet LEED Silver certification. To optimize costs and efficiency, the central energy plant utilizes an IceBank energy storage system to cool the buildings on both campuses. The firm chose CALMAC for its many benefits, including its operational efficiency and its proven reliability.
Chillers work with the CALMAC IceBank energy storage tanks to make ice at night when energy costs are significantly lower. The low-cost stored energy aids the chiller the next day to cool the buildings during peak demand. The combined campuses require 2,200 total tons of cooling capacity. By combining the two central cooling plants into one and adding ice storage, Matern was able to reduce the purchased chiller capacity to 1,200 tons.
The hybrid cooling system with ice storage reduced not only the HVAC equipment size and refrigerant required for the project but also the peak energy consumption for the campus, says CALMAC, adding that the energy storage tanks are estimated to save 10 percent of the schools annual electricity costs.
