For more than a decade, the Federal Government has turned to Pepco Energy
Services to help reduce its energy use. Our list of energy saving projects
ranges from Andrews Air Force Base to the National Zoo. The annual energy
savings that are a direct result of our projects on military bases and federal
office complexes are in the millions of dollars.
Military District of Washington Pepco Energy Services Made Huge Improvements in DOD
Energy Performance
The Challenge
When the President
ordered federal agencies to cut greenhouse emissions by 30 percent, which
would save taxpayers over $750 million each year when fully implemented,
the Pentagon began an exhaustive look for possible energy improvements at
2,100 buildings on its five military installations in the
Baltimore/Washington, D.C. area. These installations, also known as the
Military District of Washington, consist of Fort Belvoir, Fort A.P. Hill,
Fort Myer, Fort McNair and Fort Meade.
With the assistance of the Department of Energy's National Renewable
Energy Lab, the Department of Defense (DOD) sought bids from private
sector experts to provide solutions to the energy needs of the Military
District of Washington. After a very competitive bid process, the DOD
awarded the largest ever Energy Savings Performance Contract (ESPC) to
Pepco Energy Services to provide a range of services including energy
engineering, equipment installation, construction supervision and
measurement and verification.
The Solution
Pepco Energy Services upgraded the energy performance of 688 buildings
and is maintaining the equipment for 18 years, � saving over $200 million
in energy costs during the contract term and 72,000 metric tons of CO2
(MTC/yr). The equivalent of removing 57,000 cars from the road each year.
The Pepco Energy Services solution included the following:
-
Lighting retrofits and replacements
of 150,000 light fixtures in 550 buildings, reducing annual energy consumption
by 20.6 million kWh.
-
Cooling system retrofits and replacements
for 460 cooling units, reducing annual energy consumption by 7.6 million kWh.
-
Air handling unit replacements and retrofitting
for 430 air handling units in 90 buildings, reducing annual energy consumption
by 14 million kWh.
-
Central heating plant upgrades with new gas-fired boilers
at two central steam plants, reducing annual energy consumption by 64,000
MMBTU.
-
Central cooling plant upgrades
including a new absorption chiller and chilled-water distribution line,
reducing annual energy consumption by 1.7 million kWh.
-
Water consumption and wastewater conservation measures in 160 buildings,
retrofitting 550 existing plumbing fixtures with ultra-low-flow units, reducing
annual water consumption by 30.1 million gallons.
