Con Edison’s Green Team has helped Columbia University save more than $700,000 a year in energy costs through upgrades to the school’s water-chilling system.
The university received $469,000 in incentives through Con Edison’s Commercial & Industrial Energy Efficiency Program to offset part of the project’s $2.25 million cost. The upgrade will reduce electricity usage at Columbia’s campus in Manhattan’s Morningside Heights neighborhood by 3.5 million kWh a year. The school will recoup its investment in just over two years.
The project, a key part of Columbia’s campaign to reduce its energy consumption, consisted of installing a comprehensive network of controls, metering, hardware, programming software, and other upgrades to the school’s chilled water system.
Columbia selected Johnson Controls and Optimum Energy to install the new equipment.
The new metering equipment and programming software allow the University to closely measure and control energy use within the chiller plant.
