To reduce apparent scale and to support efficient densely packed equipment layouts, two offset volumes individually respond to unique engineering requirements, while reducing building size. The interior required a large, double-height space housing six chillers and related equipment. An upper mezzanine floor with control-room flanks the chiller hall and overlooks the open activities below. A low water table allowed a full basement to further reduce building footprint. Plant safety and ease of operations and maintenance were key requirements including ease of removal and replacement of equipment in future. An interior truck driveway does double-duty in also providing the lateral “pull space’ required for cleaning the chillers at ground level. Crane movement provides access to all levels throughout the two-story chiller hall, with crane access via hatches from this level to the basement below and via hatches from the roof to ground level. Meeting sustainability objectives, the new plant is LEED Certified. The innovation of a partially cantilevered rooftop cooling tower array allowed the cooling tower screening to also shade the building on the south and most of the east and west facade (the west facade is further shaded by an existing parking garage). Digital sun/shadow modeling indicated that the effect of this screening in combination with the translucent ceramic frit on the glass did not require an additional “low-e” coating on the low iron glass resulting in an exceptionally crystalline appearance. The goal of the new plant was to significantly improve campus central plant reliability, energy efficiency and environmental air quality, and this has been achieved.
