Yes, I did that already.
But can you have multiple source zones for the same receiving zone?

There is a modeling trick that can be used as a work around for more than
one simple Ventilation object to act on a zone. 1) Create small, simple
dummy Zone(s) that is/are not really part of the model. 2) Apply the extra
Ventilation objects to those dummy zones. 3) Connect each dummy Zone to
the actual Zone using pairs of Mixing objects with pretty high flow rates
for good mixing.

Ventilation
Hi.
I´m doing my master in mixed-mode conditioned office buildings (in Brazil)
and I´m just learnig about Energy plus and comparing it with TAS.
So, I´ll have the same problem as Rory and Arno: I want to simulate the
combination of natural ventilation and air conditioning, using air
conditioning (or mechanical ventilation) only when it´s necessary, depending
on the outside conditions (temp and humidity). Is it possible with E+??
Tks a lot.

Hello.
I have the same porblem as Rory.
So, it is possible to have more than one ventilation object for the same
zone?
And how can I combine natural ventilation with mechanical ventilation in one
zone?
Regards, Arno.

Hello
I would like to implement the following ventilation control strategy for a
single zone in energyplus.
Daytime 08.00 - 16.00 Ventilate at 3ACH if the internal temperature is
above 22C.
Nighttime 16.00 - 08.00 Ventilate at 2ACH if the internal temperature is
above 20C.
I have been able to implement Daytime ventilation and Nighttime ventilation
by setting up two Ventilation Objects.
But can only get one of these ventilation controls to work at a time.
ie in the results, ventilation only occurs at night but not during the day,
or vice versa.
Is it possible to get both control strategies to work using simple
ventilation objects.
Thanks again
Rory
