Capital Projects
Energy Performance Projects |
In 2003 Onondaga County
and Carrier Corporation partnered in an effort to reduce energy
in the top 25 highest energy using sites, which represented
80% of the Counties annual energy use. Through this partnership,
the County has to date implemented energy-savings projects in
more than half of these sites.
In November of 2005, the County Legislature authorized funding
for energy saving projects at the District Heating and Cooling
(DH&C) Plant, War Memorial and Civic Center. It is estimated
that these projects will permanently eliminate the annual usage
of 1,036,535 therms that represents 21.7% of the County's total
natural gas use. In addition, these projects will eliminate
electricity usage of an additional 0.8 million kilowatt-hours
per year.
The County will also receive $650,000 in NYSERDA funding for
these projects.

With the pending Chilled
Water upgrade project, the District Heating and Cooling plant
will shift it's primary/base load cooling equipment from the
steam driven absorption chillers too much higher efficiency
electric centrifugal chillers. The summer operation of the plant
will no longer require the operation of the larger 45-55,000
lb / hr. boilers which are inefficient when run at lower steam
loads. However, the county still needs summer steam primarily
to make up domestic hot water for the downtown complex and operate
the Justice Center kitchen. To accomplish that, this project
will replace the oldest of three large boilers with a 400hp
- 13,000 lb / hr. energy efficient summer boiler.
The operation of the summer boiler in lieu of the existing boiler
is anticipated to save 18,480 Therm/yr and 83,790 kWh/yr.
War Memorial
The War Memorial facility will undergo multiple energy savings
improvements. The project includes the implementation of a natural
gas engine ice rink compressor with heat recovery to reduce
electrical energy consumption and the installation of high-efficient
motors and pumps. Air quality and energy consumption will improve
with the implementation of demand control ventilation. Demand
control ventilation, or DCV, brings in fresh air based on occupancy
levels through the measurement of carbon dioxide within the
facility. This will eliminate the need to constantly condition
air when not needed and save energy. The project also includes
the installation of a low emissivity ceiling to the underside
of the roof to reduce radiant heat transfer to the arena and
eliminate moisture and condensation problems. The project is
underway with completion expected fall 2006. The project has
a simple payback of approximately eight years.
