The Center on Global Energy Policy's Women toured the Central Energy Plant of Columbia University's new Manhattanville Campus. The tour was led by Michael Haeser, Manhattanville's Director of District Energy System, and Sejal Shah, Manhattanville's Manager of District Energy Systems. It started from the courtyard in front of the Lenfest Center for the Arts where participants were introduced to the buildings the plant currently supports, then we went down to the Central Energy Plant. We walked through the control rooms and learn about the different systems that monitor the equipment (boiler/chiller). The group then walked through the plants where Michael and Sejal discussed what the boiler and chiller do and what other pieces of equipment the plant uses to ensure a smooth operation. They also provided details on the refrigeration cycle, free cooling, steam, condensate, efficiency, and sustainability.
