Client: University of Rochester
Year: 2005 to 2019
Project Highlights
- More than 71 buildings converted from steam to hot water
- Design & Construction Support of over 71 ETSs
- More than 20,000 trench feet of EN253 Piping Installed
- System peak hot water load of 58 MW
Steam to Hot Water Conversion and System Expansion project increased efficiency by more than 30%
FVB designed, supervised construction, and commissioned a low-temperature hot water district heating network and related building connections, replacing the institution’s aging steam system. The conversion to hot water was an integral part of a new 25-megawatt (MW) electric combined heat and power (CHP) system. Thermal distribution efficiency was increased by more than 30 percent, and the new hot water system was constructed and commissioned in 10 months without loss of service to users, including the Medical Center. Operation began in Oct. 2005.
FVB prepared a conceptual design for conversion of the entire campus to hot water. The University has implemented conversion of about half of the campus to date. FVB’s scope of work included design development, construction documents, construction support and commissioning for:
- Production of 250 million Btu/hour of low temperature hot water
- 17,000 trench feet of hot water distribution piping
- 118 building connections
The customer connections used brazed plate and shell-and-coil heat exchangers for building heating and double wall plate-and-frame heat exchangers for domestic hot water heating.
FVB also designed the expansion of the chilled water distribution loop serving Medical campus at the University. FVB prepared a design package for use in soliciting bids for project construction and installation. FVB has supervised and coordinated preparation of engineering and construction documents for the underground piping, the connections to the existing piping network, and provisions for direct interconnections to four buildings. Specifications for the required earthwork and restoration were included as part of the construction documents.
