New central plant includes a chiller plant, boiler plant and emergency generators. The plant building is a new stand-alone building separate from the existing hospital which allows the existing chillers, boilers and emergency generators to remain operational until construction of the new plant and the piped utilities are complete.

• Four 350 HP high pressure steam boilers utilizing natural gas with fuel oil back-up
• 20,000 gallon fuel oil storage tank
• Boiler oxygen trim and boiler blow-down heat recovery
• Reverse osmosis water system to provide boiler make-up water and minimize the use of boiler chemicals
• Three 1500 kW emergency generators
• Hybrid chiller plant consisting of three 800 ton centrifugal chillers with variable frequency drives and one 800 ton two-stage steam absorption chiller
• Cooling towers with variable frequency drives and discharge sound attenuation
• Primary/secondary chilled water distribution system with a variable flow secondary system
• Winter hydronic economizer utilizing the cooling towers and a plate-and-frame heat exchangers

• Extensive acoustic analysis performed and significant sound treatment incorporated into the design in order to comply with stringent Highland Park noise criteria
• Computational fluid dynamics re-ingestion study performed in order to predict any adverse affects of the effluent discharged from the plant in the existing hospital. The study determined the minimum height of the boiler stack.
