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

Hey @shorowit. Natural_Ventilation_Test schedule is used by the ventilation control. Here is a drive link for the IDF al

@shorowit, I use BeginTimestepBeforePredictor for all of the programs.

EMS schedule for Natural Ventilation Hey everyone, I believe it would be a good idea to have this as a separate questi

Hey @shorowit, Thank you for your comment. I have further investigated the script. A schedule control also needed to be

Hello,

I was previously trying to figure out the CO2 EMS code which I was able to get working. Essentially, I want my model to access the Natural Ventilation with the Temperature control and CO2 sensors together. But, the results I've noticed is that with the CO2 EMS script, the temperature control has been disregarded. I've tried to include both temperature control and CO2 sensors in my script but havent had any luck.

CO2 Control

EnergyManagementSystem:Program,
    CO2_Sensor09,            !- Name
    IF EMS_CO2_Sensor07 > 800,  !- Program Line 1
    SET OpenFactor09 = 1.0,  !- Program Line 2
    ELSE,                    !- A4
    SET OpenFactor09 = 0.0,  !- A5
    ENDIF ;

Temp Control

EnergyManagementSystem:Program,
    Temp_Program02,            !- Name
    IF Temperature_Sensor01 > 23,  !- Program Line 1
    SET Temp_OpenFactor01 = 1.0, !- Program Line 2
    ELSE,  !- A4
    SET Temp_OpenFactor01 = 0.0,  !- A5
    ENDIF ;  !- A6

EMS control with both Temperature and CO2. This does not work, maybe due to an error in my EMS sensor script below. I had to seperate the Output variables as it would not work when "Zone Air CO2 Conc" and "Zone Air Mean Temperature" Ran together.

EnergyManagementSystem:Sensor,
    EMS_CO2_Sensor09,        !- Name
    SecondFloorStudy,  !- Output:Variable or Output:Meter Index Key Name
    Zone Air CO2 Concentration;  !- Output:Variable or Output:Meter Name

EnergyManagementSystem:Sensor,
    Temperature_Sensor01,        !- Name
    AtticBedroom-cutout,  !- Output:Variable or Output:Meter Index Key Name
    Zone Mean Air Temperature;  !- Output:Variable or Output:Meter Name

EnergyManagementSystem:Actuator,
    OpenFactor01,            !- Name
    Window_4_Opening,  !- Actuated Component Unique Name
    Zone Ventilation,        !- Actuated Component Type
    Air Exchange Flow Rate;  !- Actuated Component Control Type

EnergyManagementSystem:Program,
    CO2_Sensor09,            !- Name
    IF EMS_CO2_Sensor07 > 800,  !- Program Line 1
    AND Temperature_Sensor07 > 26, !- Program Line 2
    SET OpenFactor09 = 1.0,  !- A4
    ELSE,                    !- A5
    SET OpenFactor09 = 0.0,  !- A6
    ENDIF ;                  !- A7

This is the error I get when I run the above script

1.    ** Severe  ** Errors found parsing EMS Runtime Language program or subroutine = CO2_SENSOR01

Can anyone help me figure out the script that could include both temperature and CO2 control?

Cheers, Adarsh

Hey @shorowit Thank you ! Following your input, I just had to set an OR function instead of AND and it works out well.
