Can IESVE Model Static Pressure Reset Based on Box Position?
Yes, in two respects: You can model "static pressure reset" to model a standard VAV system wherein you control (reset) the speed of the fan to maintain constant static pressure at the air handler, and thus also essentially constant pressure in the VAV boxes. You would do this by inputting a constant total static pressure (TSP) in each of the rows in the fan characteristic table. This would mean that regardless of the flowrate of the fan, the static pressure would be constant at all times. This is the standard configuration for baseline VAV systems in Apache HVAC.
If you want to model the resetting or variation of static pressure to optimize system performance, you will need to create a predefined TSP curve to represent the optimum performance of the fan. This would then be equivalent to resetting the fan speed and static pressure target to be maintained at any given flow rate. As the VAV boxes open or close, the flow rate will vary, and this will, in turn, vary the static pressure value in accordance with the five data points you provide.
However, you cannot model dynamic reset where the static pressure target at any given flow rate actually changes in response to system dynamics other than the cumulative downstream demand for airflow (per the combined effect of zone VAV box controls).
