Continuous Commissioning of a Medical Research Facility

Abstract

This paper presents a case study for Continuous Commissioning® (CC®)of a 520,000 square foot medical research facility. All of the primary energy using systems in the building were investigated to determine their existing condition and operation. Using these findings, the needed CC® measures were developed. Some of the CC® measures include repairing the heat exchangers, valves, and dampers that are not working. Also, reset schedules for air handling unit supply temperature and static pressure were created. Chilled and hot water loop ?P setpoints were fine-tuned. Economizer operation and air-to-air heat exchanger operation were also optimized. The airflow stations in many of the terminal boxes were found to be in need of cleaning and addition of filters. From January 2004 through March 2006 the CC® engineers implemented the CC® measures with the assistance of facility staff. Cumulative CC® savings from April 2004 to July 2006 was over $1,900,000 and the building experiencd significant comfort improvements.
