Ross Barney Architects design large-scale Chiller Plant for Ohio State University
The South Campus Central Chiller Plant will provide the Medical District of the Ohio State University a long term, efficient and sustainable solution for chilled water production and distribution. Durability and redundancy will be addressed with a modular design with additional components of all critical equipment to maintain 12,500 tonnes of chilled water for the medical centre customers.
The Chiller Plant will be constructed in the current location of a surface parking lot west of the College of Pharmacy. The site is currently below the flood plain and will require underground utility relocations and the location of critical equipment above this elevation.
The chillers themselves will be installed in phases to address requirements of the medical centre and will be remotely controlled at the central power plant with robust industrial control systems. Phase one of the project will be a minimum of 15,000 tonnes for the new Cancer and Critical Care Tower and the gradual replacement of aging equipment located in existing buildings of the medical campus.
The materials for the new plant will be concrete precast panels with a high sheen polish finish. Large glazed openings are located to help identify the function of the building by framing views of the chiller equipment. Since there are no visible moving parts, dichoric glass fins located in the joints of the precast panels, will convey a sense of motion as the colours change from the movement of the sun. The design incorporates sustainable principals and will be integrated with the planning of LEED certification of other District facilities.
To further increase reliability, emergency power will be installed with the Chiller Plant to provide chilled water for critical operations during power outages. The ultimate capacity of the Chiller Plant will be 30,000 tonnes of chilled water.
