Construction

District Cooling System Expansion

The proposed expansion of the District Cooling System will utilize the chilled water plant at the Donaghey Student Center (DSC) to provide chilled water supply to Ottenheimer Library, SUA, SUB, Stabler Hall, and the Center for Performing Arts. Currently, these buildings are served by old, inefficient independent chillers.

Under the proposed expansion, these chillers will be removed from service with the exception for the chillers at the library, which will be used in standby duty only. Once the proposed expansion is complete, these buildings will utilize the high-efficiency water-cooled DSC plant with variable flow operation. In addition, the upgraded DSC plant allows for hydronic free cooling through the use of a plate and frame heat exchanger during the cooler seasonal months.

In addition to the associated building modifications, the proposed expansion will include trenching to install below-grade supply and return piping under five construction phases as shown in the associated map.
