NYPA To Cut Energy Use In Half At Its White Plains
Offices: Initiatives address Governor’s energy-saving goal
FOR IMMEDIATE RELEASE
WHITE PLAINS—Louis P. Ciminelli, acting
chairman of the New York Power Authority (NYPA), today announced a $3.5
million program to install energy efficiency improvements in its White
Plains offices, The Clarence D. Rappleyea Building at 123 Main Street.
NYPA’s energy-saving initiatives will cut the building’s energy use
by more than 50 percent and are being implemented as part of Governor
George E. Pataki’s goal of reducing state building energy use. In June
2001, Governor Pataki issued Executive Order No. 111, which includes the
requirement all state buildings to reduce energy use by 35 percent by 2010
relative to 1990 levels.
"The energy efficiency improvements undertaken by the Power
Authority at our largest office facility will serve as a showcase for
economic and environmental benefits of energy-savings," said
"Under Governor Pataki’s leadership, the Power Authority has
more than doubled its annual investment in energy efficiency and clean
energy technologies. NYPA now provides more than $100 million annually to
help schools, local governments and state agencies save energy. The
1,000-plus projects NYPA has completed across the state are producing $74
million annually in reduced energy bills and taxpayer savings,"
"White Plains is pleased to have the Power Authority highlighting
energy efficiency building practices in our downtown. We’ve been working
closely with the Power Authority to meet Governor Pataki’s aim of
reducing energy use, which saves taxpayers’ dollars and also preserves
the environment, through initiatives including electric vehicles and
energy efficient lighting at many city facilities," said Mayor Joseph
Delfino, City of White Plains.
"By replacing older fixtures with high-efficiency lighting; using
motion-sensors to turn off lights in unoccupied rooms; replacing aging
chiller plants with more advanced units and installing computer-controlled
energy management systems, this NYPA building will be a model for
energy-savings," stated Eugene W. Zeltmann, president and chief
operating officer of the Power Authority.
Replacing the 21-year-old chilled water plant, which has reached the
end of its useful life, is the major component of these improvements.
Installing two new 460-ton chillers and associated cooling towers, valves,
controls plus two sets of chilled water and condenser water pumps, will
reduce energy use by 2.6 million kWh (kilowatt hours) for projected annual
savings of over $191,000. Included in this project is the replacement of
three Leibert AC units in NYPA’s computer room and two wall units will
be replaced with high efficiency units. Total installed cost for the
cooling systems project is $2.4 million.
Additional measures in this project include upgrades in lighting and
computerization of mechanical environmental controls; installation of
occupancy sensors in offices and common areas; lighting improvements in
the building’s garage, and a power control system that reduces the power
requirement for all existing lighting fixtures.
A computerized control system plus premium efficiency motors for fans
and pumps, for the building’s heating, ventilation and air-conditioning
system, will be installed to provide greater efficiency with reduced
energy use, while maintaining comfort levels.
Cooling costs will be further reduced by the installation of
reflective, thermal film on all windows to reduce the summer sun heat
The upgrade in lighting and automated control systems will cost about
$1.1 million with annual savings of over $120,000 on electricity costs.
Energy use reductions of 1.9 million kWh are also expected. Total
installed cost of the entire program is $3.5 million with energy use
reductions of 4.5 million kWh leading to annually recurring energy savings
of over $313,000. Including energy efficient building improvements
previously done, the Power Authority has estimated energy reductions in
excess of 50 per cent at this building from 1990 levels.
This project builds on extensive energy efficiency improvements in
controlling air ventilation and lighting installed by NYPA in 1996-97.
In addition to energy efficiency projects, NYPA is using the Rappleyea
building as a working laboratory for commercial applications of advanced
"clean, green" energy technologies. On NYPA’s roof is a solar
energy demonstration. The photovoltaic system delivers 5.5 kW to power
parts of the building. A microturbine—clean
energy system about the size of a refrigerator—is
also used by NYPA to generate power and heat for the building. The
building's garage includes charging stations for an array of emission-free
The Power Authority is reviewing potential energy savings at the other
buildings it owns and leases to assure compliance with the Governor’s
Executive Order 111.
To assist with the implementation of the order, Governor Pataki
introduced legislation, under consideration by the Senate and Assembly, to
remove regulatory barriers and enhance the benefits of energy efficiency
programs available to state agencies, local governments and school
districts from NYPA and the New York State Energy Research Development
The Clarence D. Rappleyea Building, named after a former NYPA chairman
and chief executive officer, is located in the heart of downtown White
Plains. About 650 Power Authority staff members occupy about half of the
building’s 420,000 square feet, with the balance leased to others. Built
in 1981, it was purchased by the Power Authority in 1991 after leasing
space in the building since 1982.
