This paper demonstrates the implementation of new innovative technologies during continuous commissioning (CC) practices to improve building operations and reduce energy costs. A 46-year-old typical commercial building with a floor area of about 216,000 square feet was used as a case study building. The new technologies include a fan airflow measurement method for building pressure control and duct static pressure reset, and a recently developed pump water flow station for secondary pump control. The results show that these technologies improve building operation and maintenance and significantly reduce energy costs. The monthly average electricity savings for HVAC is more than 70% per month for the three months of the monitoring period. The total building electricity savings is 36.7% on average. The gas savings is about 48% for the two months of the monitoring period.
