The Swiss Re Americas Headquarters Building is a 420,000 square foot office building. OLA was brought on board to perform an energy audit of the campus and look at replacement options for the aging absorption chiller plant. Energy measures included upgrades to the central chiller and boiler plant, domestic hot water system, airside systems, lighting, HVAC and lighting controls, and building envelope. OLA provided solar system consulting for a 2.7 MW ground-mounted photovoltaic solar array covering the 10 acres. It is the largest solar array in Westchester County and currently provides 60 percent of the power to the headquarters building. The energy reduction project received a Platinum Award for Energy Engineering from the New York Chapter of the American Council of Engineering Companies (ACEC).
