Preserving historic buildings also means preserving the hidden infrastructure that powers them.
For Yale University’s 1918 Central Power Plant (CPP), RMF helped transform an aging cooling tower installation into a modern, efficient system designed to support the university’s evolving campus needs without interrupting operations or losing sight of the facility’s historic context and neo-Gothic and Georgian architectural styles, representing the latest in a series of successful modernization projects conducted by RMF at the site.
Providing steam, electricity, and chilled water to Yale’s main campus and Science Hill area, the project required navigating the realities of a century-old plant shaped by limited space, decades of modifications, ongoing utility production, and strict noise, aesthetic, and operational requirements.
During design, RMF and architect Pirie Associates Architects teamed with Wiss, Janney, Elstner Associates - WJE to evaluate existing building conditions and incorporate those considerations into the construction modernization effort. This included a visual assessment of the masonry structure, brick repointing and staining to maintain continuity with the existing façade, installation of a new roof beneath the cooling tower array, and restoration work addressing deteriorated architectural elements. One of the project’s enhancements involved the southern battlement, where substantial brick displacement and limestone spalling required removal of deteriorated materials and installation of new limestone coping to restore structural integrity while preserving the building’s historic appearance.
Working alongside Pirie Associates, whose scope required approval through the New Haven Historic Commission, the project team carefully balanced modernization goals with the building’s historic aesthetic. A notable design element included acoustically engineered screening featuring louvers and metal panels that improved airflow, aesthetics, and sound control around the new four-cell, high-efficiency, field-erected cooling tower array designed to reject 263 MMBTU/hr. of heat supporting 9,000 tons of campus chiller capacity. The modernization also included piping, electrical, DCS controls, and structural upgrades.
Laser scanning, BIM coordination, and rigorous shutdown planning enabled accurate design and construction coordination within a constrained, continuously operating utility plant, helping minimize risk and streamline ex*****on during a limited off-season shutdown window.
