The University of Massachusetts-Boston is in the midst of a major infrastructure project involving the development of a new utility corridor and roadway network for its 175-acre campus overlooking the Boston harbor. As part of the project, the school’s 40-year-old central utility plant also will be upgraded to a more energy-efficient primary and secondary pumping arrangement that serves the campus’ hot- and chilled-water utility loop.
The upgrade includes four 2,000-ton centrifugal chillers, three 800-HP boilers and one 400-HP boiler. The new hot water system has piping sizes up to 16 in. diameter and the chilled water system had diameters up to 30 in.
