Hello, I have a problem when I model my buildings in Sketchup (pro 2022), with the OpenStudio plugin (v1.4.0). Indeed, when I want to rename a space for example, as soon as I use a shortcut key of a tool or a feature, instead of typing the letter, sketchup selects the tool in question... Which is really not practical. I can't find the solution to this problem. Has anyone encountered this before? Thanks in advance!

Thanks a lot Aaron! It works fine!

Hi everybody,

I modified an EMS control script in DesignBuilder to control the opening of external windows to provide free cooling on spaces which are too hot. I only want the occupants to open the windows when zone is occupied. The first part of the code works fine. But I want to do another thing: To prevent overheat, when people arrive in the morning (7 am), during the summer, they always open the window until 9am, to cool the space in prevention (use of thermal inertia of the space). So, I tried to add some boolean expression to do this, but it don't works. I don't know if I can nest boolean expression, or if there is an easier way to do what I want.

<ForAllExternalWindows>
EnergyManagementSystem:Sensor,
   Zone_People_Occupant_Count_<LoopWindowVariableName>,
   <LoopWindowZoneIDFName>,
   Zone People Occupant Count;
<LoopNextWindow>

<ForAllExternalWindows>
EnergyManagementSystem:Actuator,
      Venting_Opening_Factor_<LoopWindowVariableName>,
      <LoopWindowIDFName>,
      AirFlow Network Window/Door Opening,
      Venting Opening Factor;
<LoopNextWindow>

EnergyManagementSystem:ProgramCallingManager,
   Natural ventilation,
   BeginTimestepBeforePredictor,
   NatVent;

EnergyManagementSystem:Program,
   NatVent,
    <ForAllExternalWindows>
    IF Zone_People_Occupant_Count_<LoopWindowVariableName> == 0,        
        SET Venting_Opening_Factor_<LoopWindowVariableName> = 0,
    ELSEIF (Zone_People_Occupant_Count_<LoopWindowVariableName> > 0),
    <IF LoopWindowAttribute Month >=5 Then>
    <IF LoopWindowAttribute Month <=9 Then>
    <IF LoopWindowAttribute Hour >=7 Then>
    <IF LoopWindowAttribute Hour <=9 Then>
        SET Venting_Opening_Factor_<LoopWindowVariableName> = 1,
    <endif>
    <endif>
    <endif>
    <endif>
    ELSE,
        SET Venting_Opening_Factor_<LoopWindowVariableName> = null,
    ENDIF,
<LoopNextWindow>

Hi, Using OpenStudio2.7.0, I think there is a problem with SIELAO. We have no more the possibility to add a schedule on the SIELAO. So, when I run the simulation, I have the following error message:

"* Severe * <root>[ZoneInfiltration:EffectiveLeakageArea][Space Infiltration Effective Leakage Area 1] - Missing required property 'schedule_name'.".

Is it a known issue, or am I doing something wrong? Thx!

Thx for your answers!
