Utilization of the Continuous Commissioning® process is presented in the case of the Consolidated Mission Support Center office building at Travis Air Force Base in Travis, California. The CC® process was applied to the building in early 2003. The examination of the heating, ventilating, and airconditioning (HVAC) and control systems revealed several areas where considerable improvement could be made, including air handling unit (AHU) operational parameters, terminal box and water loop operation, and Energy Management and Control System (EMCS) functionality. It also aided in the identification of mechanical systems needing repair. The optimization of the HVAC systems and advanced utilization of the EMCS reduced the combined heating and cooling energy consumption by 26% without capital intensive upgrades. Cooling energy decreased by 10%, heating energy was cut by over 40%, and fan power decreased by 28%. A hidden benefit to the implementation of the CC® process is the reduction in the human capital required to operate the building. Prior to commissioning, significant time was spent changing system operating setpoints in an attempt to save energy. These efforts are no longer required.
