[Equest-users] Sizing of equipment

[Kairento, Janne]

Hey All,

I am running a load with many zones on 5 floors totaling over 300 zones. There are some zones with many unmet hours, some of the core, some perimeter. I went in and changed the sizing ratio of these zone to reduce the unmet heating hours. I am modeling this building with 9 AHU's, all VAV w/ reheat. Does anyone have any insight or suggestions on why or how these unmet hrs. exist. I have changed the hot water loop flow GPM but it had no effect on the unmet heating hrs. so I deduced this is not the cause.
