NYPA White Plains Office Building’s Energy Use Cut in
Half: Project Addresses Governor's “Green and Clean” State Building Goals

energy efficiency technologies installed by the New York Power Authority (NYPA)
at the Clarence D. Rappleyea Building, NYPA's White Plains headquarters,
will reduce the building's energy consumption by more than 50 percent and
will save over $400,000 annually.
"When it comes to saving energy, cutting costs and protecting the
environment with advanced energy technologies, New York State and the New
York Power Authority are leading by example,” said NYPA Chairman Louis P.
Last March, NYPA began a $3.8 million dollar project at its office at 123
Main Street to address Governor George Pataki's Executive Order No.111,
which requires that state-owned buildings achieve ambitious energy-saving
goals. The Governor's “Green and Clean State Buildings” order requires
energy use reductions of at least 35 percent by 2010; based on 1990
Along with the energy savings of 50 percent, the White Plains Office
improvements will help reduce greenhouse gas emissions by 4,100 tons each
NYPA’s energy-saving project incorporated a number of different energy
technologies ranging from the replacement of its chilled water plant, which
produces cool air for the air-conditioning system; to the installation of
energy-saving lighting and an energy management system.
A significant portion of the energy savings are based on the replacement of
the building’s 21-year-old chilled water cooling plant, which had reached
the end of its expected lifespan. The new chiller and its support equipment
were installed last winter and brought on line in time for the summer
cooling season. The new chiller is responsible for lowering energy
consumption by 2.6 million kilowatt hours, the over all energy reduction
exceeds 5 million kilowatt hours.
Lighting technologies, new variable speed drive motors, a window film, and
an energy management system highlight the remaining systems installed
throughout the building. Lighting fixtures were replaced with high
efficiency units which produce improved illumination with less electricity.
A "daylight harvesting" system will deactivate garage lighting when sunlight
provides sufficient illumination. New premium efficient motors for fans,
pumps and other ventilation systems replaced older less-efficient units.
A new energy management system will provide computerized control of the
heating, ventilation and air-conditioning equipment to minimize energy use
while maintaining comfort levels throughout the building.
Under the leadership of Governor Pataki, NYPA has more than doubled its
annual investments in energy efficiency and clean energy technologies,
providing as much as $100 million a year for energy-saving projects at
public facilities in New York State.
The New York Power Authority has been designated an Energy Partner by the
federal Environmental Protection Agency for its work in providing
energy-savings at schools, colleges and government buildings across the
state. To date, NYPA has completed 1200 projects at more than 2000
