Abstract: Although the control logic and parameters of variable-airvolume (VAV) systems are essential for their performance, they are rarely considered in the design phase because of their complexity. In addition, in many cases, rooms are used under operating conditions different from those assumed in the design phase. However, reliable energy savings are still required. This study examined the usefulness of an integrated simulation in the design phase for detailed studies of a VAV system, including adjustments in control logic and parameters. The results highlight the significance of a comprehensive design of control logic, parameters, equipment selection, and zoning based on evidence from a simulation.
