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
