About 3.5 million kWh of electricity was CI (Leadership in Energy and Environmental
saved by system commissioning. For instance,
elimination of the primary constant pumps at
the secondary sides of heat exchangers led to
more than 1 million kWh of energy savings in
a year. The improved variable speed operation
of cooling tower fans resulted in more annual
energy savings of up to 2.36 million kWh.
Optimal control strategies were further
implemented for energy efficient operations,
which contributed about 3.5 million kWh of
electricity saving when compared with the
original conventional control. Examples of
