Based on the answers here and the minimal example here @Julien Marrec, I understand how to set the setpoint once I have the shading control object.

However, I don't want to create a new SC, but find all existing ones.

The following line:

scs = model.getObjectsByType("ShadingControl".to_IddObjectType)

returns an uninformative error:

 eval:1:in `initialize': Unknown Value (RuntimeError)

in an OpenStudio measure. Should I be using an EnergyPlus measure instead?

A good place to start getting familiar with measures is the Measure Writing Guide as well as looking at example measures found on BCL for example.

Use model.getShadingControls which will return an array of your shading controls.

Example: set all Shading Control's setpoint to 250:

model.getShadingControls.each do |sc|
   sc.setSetpoint(250)
end

Note that this is true of all objects in the OS API. If you want to get all Constructions in the model: model.getConstructions, etc.


Side note:

FYI, if you decompose your command call (always a good idea), you'll see that your problem is with ("ShadingControl".to_IddObjectType). This does work:

model.getObjectsByType("OS_ShadingControl".to_IddObjectType)

but it'll return an array of WorkspaceObject, that you'll have to cast to their actual object type (x.to_ShadingControl.get).

Bottom line: use model.getShadingControls!
