EMS schedule for Natural Ventilation
Hey everyone,
I believe it would be a good idea to have this as a separate question and not link it with my previous one.
After further investigating the previous script. A schedule control was also needed to be incorporated into my EMS script where the schedule calls the window to open for 15 minutes twice a day. Unfortunately, the results aren't looking like how they should.
EnergyManagementSystem:Sensor,
NatVentSchedule_Sensor01, !- Name
AtticBedroom-cutout, !- Output:Variable or Output:Meter Index Key Name
Zone Mean Air Temperature; !- Output:Variable or Output:Meter Name
EnergyManagementSystem:Actuator,
OpenFactorSchedule, !- Name
Natural_Ventilation_Test, !- Actuated Component Unique Name
Schedule:Year, !- Actuated Component Type
Schedule Value; !- Actuated Component Control Type
EnergyManagementSystem:Program,
CO2_Sensor01, !- Name
IF (EMS_CO2_Sensor02 > 1000) || (Temperature_Sensor02 >= 23) || (NatVentSchedule_Sensor02 > 0.2) , !- Program Line 1
SET OpenFactor01 = 1.0, !- Program Line 2
SET OpenFactorSchedule = 1.0, !- A4
ELSE, !- A5
SET OpenFactor01 = 0.0, !- A6
SET OpenFactorSchedule = 0.0, !- A7
ENDIF; !- A8
The schedule is an On-Off schedule with 1 calling the window to open. When I look at my indoor CO2 levels and the EUI, it looks to be that the window opens throughout the day.
I would appreciate it if anyone could help me out with this script.
Cheers, Adarsh
What calling point are you using?
@shorowit, I use BeginTimestepBeforePredictor for all of the programs.
What object is using the "Natural_Ventilation_Test" schedule? Hard to help without seeing more. Can you provide an IDF via Dropbox or Google Drive?
Hey @shorowit. Natural_Ventilation_Test schedule is used by the ventilation control. Here is a drive link for the IDF along with the IDF for the schedule (lower timestep) and the EMS control.
Hey @shorowit, I hope you're well. I'm just checking in to see if you were able to go through the IDF file? Have a nice weekend. Cheers, Adarsh
