Energy conservation through continuous commissioning <sup>SM</sup>

This paper gives an overview of Continuous Commissioning SM, a process that optimizes building energy systems operation and typically results in a 15-20% reduction in energy consumption. The paper illustrates the procedures in the development and implementation of the Continuous Commissioning process, as well as common optimization methods for all aspects of building energy systems, including air handling units, chiller and boiler plants, water distribution loops, and thermal storage systems. Since the objective of the process is to ensure the systems remain optimized continuously, monitoring and verification issues are also discussed. The commissioning of a 676,000 ft 2 mental health campus with multiple buildings, chillers, boilers, and a thermal storage system is presented as a case study. The sub-optimal operating strategies that waste energy are discussed and the commissioning measures for HVAC systems, variable speed pumps, thermal storage system, and chillers and boilers are presented.
