Energy Services Programs
Project Profile: Hunter College
The Power Authority’s largest-ever energy services
project, included centralized climate control throughout
the four buildings of Hunter College’s main campus in mid-Manhattan.
Hunter is one of the nation’s oldest public colleges and the largest in
the City University of New York (CUNY) system.
The complex project centralized climate control
throughout the four buildings for the first time through an
$18.5-million installation of three high-efficiency chillers and three
dual-fueled boilers. The work required routing chilled water, steam and
condensate piping through the pedestrian walkway ceilings. The new
equipment replaced chillers and boilers at the end of their useful life
and will save the college close to $1.4 million in reduced energy and
maintenance costs each year.
The three 1,460-ton-capacity electric chillers were
sized to allow for sufficient chilled water production to satisfy the
entire campus today as well as future expansion projects in CUNY’s
master plan. Five new cooling tower cells, with a total capacity of
3,000 tons, were installed.
The three new boilers run on clean natural gas, with
No.2 fuel oil as a backup. Dual-fueled operation generates significant
energy costs savings and meets strict clean air requirements.
NYPA provided $10.7 million in financing for the
project, with the balance from the state Dormitory Authority. NYPA will
recover its investment from a portion of Hunter’s savings.
The Hunter project was part of the Power Authority’s
long-term energy partnership agreement with the City of the New York.
Since 1990, NYPA has upgraded energy efficiency at 18 of CUNY’s 21
campuses, for total savings of more than $ 10 million annually.
