Re: [EnergyPlus_Support] Re: Mimicking occupant behaviour - Window opening



Hi Lixing,
Here is my test file for window opening. The results are good at the current settings, however, as stated before, this would be better if I could modulate the window opening factor at zonelevel based on infiltration velocity or ACH.
The EMS with the logic is at the bottom of the idf section.
Kind regards,
Jean

Yes. Your understanding is correct. The modulation is not available for
Constant Control, because the Constant Control does not have any sensor
ranges to be modulated. It is a user control. A possible improvement is to
allow a schedule, so that users have a choice to vary opening values with
time.

Unfortunately, the current EMS override is surface based. It is possible to
allow zone level control using EMS.



Hope this helps.

Lixing

I've got some innitial results.
Q1) I would like to modulate the opening fraction at zone level similarly to
AirFlow Network Window/Door Opening,Venting Opening Factor,[Fraction] (at
surface level), but it seems this is only possible with Temperature control
not Constant control. What do you think?

I would like to modulate because at large inside/outside dTs there are huge
ACH taking place. The key here is zonelevel control.

regards,
Jean.
