Hillsborough County, on Florida’s west coast, serves
more than a million residents, including metropolitan
Tampa. The county operates more than 1.5 million
square feet of building space in downtown Tampa,
including the county’s administration office and four
court buildings. Randy Klindworth, Hillsborough County’s
Energy Manager, oversees the county mission to reduce
energy consumption in all county facilities.
While building a new courthouse, the County recognized
an opportunity to centralize chilled water production for
all downtown buildings. An energy efficient central plant
was built in 2001, but due to a lack of capital funding, the
county could not implement the necessary capacity and
piping to connect the plant to all downtown buildings.c
Hillsborough County chose Trane’s PACT (Performance
Agreement for Comfort from Trane) program to expand
the central chiller plant and implement energy saving
measures in five county buildings. Trane guarantees the
resulting savings from the project. To expand the chiller
plant, Trane installed a thermal storage system. A new
1500-ton Trane chiller charges 84 ice tanks at night when
energy rates are lower. The ice is melted
during the day to produce chilled water for
cooling. Underground chilled water pipes
distribute cold water to the five county
buildings. Two school district buildings were
also connected to the piping network,
generating revenue for the county from the
sale of chilled water. This partnership allowed
the school district to reduce construction cost
of a new school by eliminating the need for
chillers.
Trane installed a system-wide building
automation system allowing HVAC systems at
all five county buildings to be monitored from
one location. A condensate reclaim system
captures air handler condensate that is used
for cooling tower make-up, saving about three
million gallons of water per year. Lighting
retrofits, variable speed drives and air handler
upgrades complete energy conservation
measures. “The whole project, with energy
and water savings, we’re looking at $1.2
million dollars a year in savings to the county,”
said Mr. Klindworth. “That’s a direct benefit to
our taxpayers.”
From energy efficient equipment to integrated
comfort control, Trane ensures your building
operates at peak performance so you can run
your business profitably.
Located midway along the west coast of Florida, Hillsborough County has 1,048 square miles of land and
includes the incorporated cities of Tampa, Temple Terrace, and Plant City. The history of the county
government dates back to 1846, when Hillsborough was organized as FloridaÂ’snineteenthh county. In
2004, the estimated population was more than 1,150,000 persons.
