Single-duct constant volume system optimization

This paper demonstrates the implementation of new innovative technologies to improve building operations and reduce energy costs. The buildings are used as an office building with a total area of 45,429 m2. An energy audit was conducted to evaluate the building's energy performance and identify potential cost-effective energy saving opportunities. This paper presents procedures for supply fan speed control, implementations and detailed descriptions of control sequence, and operation comparisons. The results show electricity savings of 23% and gas savings of 19% over a six-month period.
