[Bldg-sim] Static Pressure Reset in eQuest

[Hall, Brendan]

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.

Subject: [Bldg-sim] 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.
