[Equest-users] Changing Ventilation Rate for some months in the year

[Seaman, Ethan]

Ahmad,

Are you trying to vary the system CFM or OA CFM?  See below for eQuest’s definition of Minimum OA Sch.  The minimum OA schedule varies the hourly OA ratio.  To create an annual schedule to vary the CFM seasonally you can create an additional set of weekly/daily schedules, and then set the run times in the annual schedule.

Hello Guys,

Did  anyone have a chance to review my question in my email below?

I found the option to add "Minimum OA Schedule" but this schedule is fraction of what? Is it fraction of the CFM/person values that we enter in the Zones? I have added this schedule and changed the fractions and the energy consumption and the heating loads have been changed but the OA air flow rate & ratio in the report SV-A has not changed? Am I missing something?

If the "Minimum OA Schedule" changes the OA flow rate, then where can I find this value? I am trying to change the OA flow rate for a specific value for only three months per year for pandemic mitigation so how can I do that?

Any help will be highly appreciated

Regards

Ahmad

How can I change the ventilation rate for a building in eQUEST software for only three months of the year (Dec, Jam & Feb)?

Your help will be highly appreciated.
