Project Profile: Headquarters Building, New
York City Police Department
One Police Plaza, the New York City Police Department’s
17-story headquarters building since 1977, faced several major problems:
Its 1,000-ton steam-driven chiller was out of commission and used a
refrigerant whose production was banned (R-11 refrigerant); and the
building needed backup cooling capacity and an emergency power system to
provide air conditioning in the event of a power failure.
In addressing these problems, NYPA’s Energy Services project team had
one overriding concern—constructing a new central chiller plant without
disrupting the 24-hour functions at the heart of NYPD operations. The
accelerated construction schedule included rigging of large pieces of
equipment on the roof and in penthouse-level mechanical equipment rooms,
more than 120 feet above street level.
Aging steam turbine equipment in the
500,000-square-foot structure was replaced with two new high-efficiency
chillers to address the cooling capacity needs and reduce operation and
maintenance costs, an emergency diesel generator to drive the chillers,
and cooling towers and air handlers to keep critical areas cool in an

costs, meeting increased cooling demands and ensuring that an
