Prism, acting as the Owner’s Representative, carried out a $1M upgrade project of the chilled water plant for the building. The focus of the upgrade was replacing 2,000 tons of cooling capacity using CFC-12 with 1,800 tons, using HCFC-123 in new high-efficiency chillers. In addition, the project included upgrading the machine room to comply with local refrigeration codes, refurbishing the cooling tower and increasing its capacity by 25%, and introducing variable flow pumping of chilled water. Subsequent mechanical projects undertaken include new exhaust and ventilation systems for the food court and retail areas, and the replacement of the direct digital control (DDC) system with a new system one. Prism has also carried out an Energy Management study of the facility to determine areas for improved efficiency, with the potential of energy consumption costs reduced by $0.25 per square foot.
