WELLESLEY COLLEGE CUP UPGRADE

SUMMARY

Ameresco retained B2Q to be the prime design engineer to complete the upgrade of the Central Utility Plant (CUP) at Wellesley College. B2Q is in progress of mechanical design in Revit, and is responsible for managing the electrical, plumbing, structural, and acoustical subconsultants while coordinating all trades within the mechanical model.

The new Central Utility Plant upgrades scope consists of two (2) new 2MW peak shaving engine generators to be deployed for demand response. The chilled water plant was also upgraded to include (2) new 800-ton water cooled centrifugal chillers & a five (5) cell rooftop cooling tower. A new 4,000 ton-hr ice storage plant was installed for additional demand response & peak shaving during the peak cooling season. The plant also required a new pony steam boiler for shoulder season operations. B2Q also designed a new plant wide controls system for integration & centralization of all equipment.
