South Chiller Plant Expansion
Occupancy: 1995
Published April 1995
The University of North Carolina's laboratory and health care facilities on its South Campus are now accommodated by the expansion of the South Chiller Plant. The 19,000-ton plant expansion, from 4,000-tons, was achieved in five separate phases. It involved the selection and control of a distribution pumping system to serve the plant and interface with the existing 12,000-ton North Chiller Plant. The ultimate design goal modulates the capacity of both plants from one central location.
The project design incorporates the following components: three 4,000-ton counterflow cooling tower cells with stringent sound requirements due to the location of the plant with respect to the campus property line; three 9,000-gpm distribution pumps with variable-frequency drives for speed control; provisions for future installation of an ice or chilled-water storage system; a micro-processor-based distributive control system; connection to the campus' existing 12.47 K/V electrical distribution system, including a 7,000 K/VA Phase I addition and 15,000- K/VA ultimate capacity; and sectionalized electrical systems utilizing multiple transformers and redundant primary feeder sources.

The cost figures reported are supplied by the firms that submitted these
projects for publication, which in most cases are the designers or builders.
Whereas these sources are intimately familiar with their projects, they may
not be fully aware of the owners' finally-realized and recorded costs. In some
cases, costs are truly and completely accounted for, and in others they represent
a near approximation of the final costs. Costs have not been adjusted for
year of construction, nor has any attempt been made to make regional cost
adjustments.
Further, costs are not comparable on any kind of detailed standard costing model.
Hence, it is possible for the cost of one building to include a steam boiler, while
the cost of a comparable building might not include the boiler, if steam is being
supplied from an already existing campus grid. Or, in another case, a building might
include excess boiler capacity to supply steam to another building. Some submittals
include fees or unusual site improvements as part of the construction costs, which
others do not.
