Precis Engineering led an in-house team of mechanical engineers for upgrades to the main hospital’s central utility plant. Engineering design was preceded by a study of the existing 1,500-ton primary-secondary plant and analysis of return on investment (ROI) for different chiller options. Key components of the project included:

  • Analysis of hospital natural gas and electric tariffs
  • Complete operating energy analysis of the central plant, including mathematical models of upgrade alternatives
  • Master plan of upgrades to the hospital’s distribution systems
  • Resolved operational problems that had plagued the hospital since original construction in 1961
  • Designed replacement chiller and new header system, upgraded pumps, and optimized cooling towers
  • Provided a new free cooling system
  • Replaced the central plant control system
