CALMAC`s Energy Storage Saves Hillsborough County Energy and Money

County Expects to See Savings of Nearly $1.2 Million Per Year in Part with Help
from 84 IceBank Tanks Installed in Florida Buildings
FAIR LAWN, N.J.--(Business Wire)--
CALMAC, a leader in energy storage systems,is part of a project to
saveHillsborough County, Florida up to $1.2 million per year. The county
installed 84 CALMAC IceBank® Energy Storage tanks to work simultaneously with
its existing chilled water plant to cool its entire office space in downtown
Tampa. By installing IceBank and updating the previous cooling system, the
county is reducing greenhouse gas emissions, reducing the load on the power grid
and saving money through the use of ice.

CALMAC`s system creates ice at night which is then used the next day to cool
county buildings, including the historic downtown courthouse, the 28-story
county center and the school board building. A green and energy-resourceful way
to cool buildings, the IceBank system is shifting the county`s energy
consumption load to off-peak times when electric rates are lower and energy is
produced more efficiently.

"Hillsborough County operates over 1.5 million square feet of building space in
downtown Tampa. During recent improvement projects, we identified an opportunity
to reduce energy consumption in all county facilities with CALMAC's IceBank
system," said Randy Klindworth, Hillsborough County energy manager. "Working
with CALMAC, we are now able to efficiently cool our downtown buildings
throughout the county, reducing our need for energy, which saves our taxpayers
money."

The two school district buildings connected to the chilled water loop network
not only provide energy-efficient cooling, but they are generating revenue for
the county from the sale of chilled water. This partnership enabled the school
district to reduce construction costs with an environmental, economical
solution.

"Our IceBank Energy System is saving Hillsborough County money in terms of
energy costs, plus generating revenue from the sale of chilled water, making the
installation a lucrative business solution," said Mark MacCracken, CALMAC CEO
and USGBC Board Member. "Our IceBank System reduced peak energy consumption for
all county buildings and immediately provided a return on investment."

Air-conditioning is the main driver of on-peak energy usage and the main culprit
in electricity shortages. Throughout the day, as more air conditioning is needed
to maintain comfortable temperatures, the demand for electricity increases the
load already created by lighting, operating equipment, computers and other
sources. CALMAC`s IceBank Energy Storage System shifts the building's energy
demand from on-peak to off-peak times which decreases cooling costs by up to 40
percent and reduces both source energy consumption and greenhouse gas emissions.
