Ameresco energy manageAmeresco completed a multi-phase renewable energy and energy efficiency project at the Adelphi Laboratory Center in Adelphi, Maryland, a research and development facility of the US Army. Under the most recent phase of the Energy Savings Performance Contract (ESPC), Ameresco installed facility-wide energy conservation measures and 2 MW of solar photovoltaic systems on carports and rooftops.

Ameresco has implemented three phases of comprehensive energy projects at the Adelphi Laboratory Center totaling $45 million. Ameresco completed the most recent phase of work this spring, which included $19.6 million worth of energy improvements through nine energy conservation measures including the replacement of five rooftop air handling units; data center HVAC improvements; lab heat recovery, rainwater harvesting; and 2 MW of solar photovoltaic, including 331 kW installed on rooftops and 1,700 kW installed through the construction of solar carports. The solar carport systems are among the largest in the Army.

During phases one and two of the ESPC, Ameresco installed a number of energy-saving measures including a 2.2 MW combined heat and power system (CHP); facility-wide lighting upgrades with occupancy/HVAC controls and outdoor LEDs; high efficiency transformers; high-efficiency chillers; humidification and dehumidification systems; high-efficiency air compressors; and an installation-wide open protocol direct digital control system with commissioning.

Ameresco also is providing long-term operations and maintenance services for the major equipment installed. The combined effect of these ESPC projects support the installation’s mission and commitment towards Federal energy and sustainability requirements, and have resulted in a site energy reduction of about 50 percent.
