[EnergyPlus_Support] Greenhouse airflow simulation

["marziasedino" <marziasedino@xxxxxxxx>]

Hello,
I am trying to simulate a greenhouse space adjacent to a two thermal 
zones building, I created the model with DesignBuilder and exported 
it in E+,
The greenhouse external wall has got a big window open during summer 
and closed during winter time.
The partition wall between the greenhouse and the adjacent thermal 
zone has got 4 detailed openings (and one main door) which should 
open as specified in the following schedule being their ventilation 
control mode "temperature":
-	during summer when the temperature of the adjacent thermal 
zone (zone name: 6346) is higher than 22°C and higher that the 
outside temperature;
-	during winter when the temperature of the greenhouse (zone 
name: 6339) is higher than 22°C and higher than the outside 
temperature.
I defined those openings twice in 
the "AirflowNetwork:Multizone:Surface": the first time considering 
them belonging to the greenhouse zone (6339) and the second time 
considering them belonging to the thermal zone (6346) in order to 
assign them the two specified different schedules (summer and winter)
as they refer to different zones temperatures.
Nevertheless when I analyse AirflowNetwork Volume Flow Rate outputs I 
can't see the openings work correctly: I expect to see more flow when 
they should be open and only infiltrations when they are closed; but 
this is not happening.

Could you tell me please if there is a better way to model them?
I uploaded my file in the appropriate space, its name 
is: "greenhouse#1"

Thanks
