CPTC Chiller Replacement Project
The Terminal Central Utilities Plant (T-CUP), which was constructed in 1978 as part
of the original Central Passenger Terminal Complex (CPTC) construction, was recently
upgraded with high-efficiency equipment. Prior to the upgrade, the T-CUP contained
two 30-year old steam-driven chillers. Two natural gas-fired boilers generated the
steam used to drive the chillers. The steam driven chillers were replaced by two
electric chillers, thus eliminating the need for the use of natural gas-fired boilers
to generate steam. The Sustainability paybacks of the project are now becoming apparent.
During the ozone season of 2007 (May through September), approximately 112.8 million
cubic feet (MMCF) of natural gas was used within the T-CUP, mainly to generate steam
for the old chillers. During the ozone season of 2008, 30.8 MMCF of natural gas was
used within the T-CUP, a 73% reduction in natural gas usage. In 2009, only 1 MMCF of
natural gas was used, realizing a 99% reduction from 2007 usage numbers.
