Static Pressure Reset in eQuest

Hi All:

I don't think this can be done in eQuest. As I understand it, it has to do with resetting the static pressure as VAV boxes close when cooling load reduces. But the only thing I see in a VAV situation is adding a variable speed drive. This would show too much fan savings versus a simple pressure reset, correct?

My controls knowledge is not large.

Thanks in advance.

In the Advanced VAV design guide by Energy Design Resources they have an appendix where they discuss how you might go about doing it in DOE2.1 / eQuest. It involves generating a custom part load curve to approximate the effect of the reset. How valid their assumptions are is up for interpretation though.
