HAL-PE Associates completed the mechanical, electrical, and plumbing design for First Financial Bank’s regional banking center in West Chester, Ohio. The mechanical systems included a VAV air handling system with chilled water cooling and hot water heating. The chilled water system utilized an air cooled, scroll chiller with full thermal storage. By generating ice during off-peak hours, the chiller was able to completely shut down during times of peak energy use. This load shifting and peak metering provided substantial savings on the Bank’s electric utilities.
