Under this 11-year Energy Services Agreement (ESA), BAE Systems pays only for the actual savings realized from the program’s comprehensive energy efficiency improvements. BAE Systems expects the program to save more than $305,000 annually in equivalent energy and operational expenses, savings delivered through a broad range of HVAC and building system retrofits and upgrades that will deliver a 5 percent reduction in electricity consumption and a 69 percent reduction in natural gas usage.
“BAE Systems is committed to improving the environment by becoming increasingly energy efficient across its North American facilities,” said Steve Hannwacker, facilities director for BAE Systems’ Greenlawn Electronics Solutions business. “The Greenlawn project’s commissioning a month early - within an already compressed timeframe - provides a benchmark, one that reveals how close collaboration with the right partner can deliver excellent results.”
As a result of the major HVAC system efficiency upgrades, local utility Long Island Power Authority (LIPA) will return to BAE Systems through its Efficiency Long Island Program an $82,000 rebate. Similarly, National Grid, BAE systems natural gas supplier, will deliver another $68,000 rebate to the company as well.
Over the course of the project, Siemens replaced existing boilers with high efficiency units, upgraded the domestic hot-water boiler, replaced two gas-fired chillers with a single magnetic bearing chiller, and completed a number of component and system swaps including upgrading controls, installing variable frequency drives, and demand control ventilation. As a result, operating and maintenance costs will be reduced and carbon emissions will be abated by up to 1,814,000 lbs per year, equivalent to annually preserving 5.8 acres from deforestation or eliminating 150 cars from the road.
