Hi everyone, I'm trying to add a EMS script with loops manually to a IDF (that is, copying and pasting the script), but I get the error below when I try to simulate. I just realised that I could use 'for loops' in eppy to add an EMS object for each zone, and therefore omit the zone loop, but i'd like to know if anyone knows an easier way to make this script with loops work, considering that the script should be added manually to the IDF.

In the following link you will see 2 IDFs: one with loops within the scrip (which works), and one without loops within the script (which doesn't work):

Thanks in advance.

See the error below:

Can you attach your IDF or upload it to DropBox or Google Drive?

Hi shorowit,

Yes, in the following link you will see 2 IDFs: one with loops within the scrip (which works), and one without loops within the script (which doesn't work):

It appears that you're conflating DesignBuilder-specific EMS code with EnergyPlus EMS code. EnergyPlus does not have builtin EMS loop commands like <ForAllUnoccupiedZones>. You can see the raw EnergyPlus EMS commands available here, while DesignBuilder extends the available commands as described here.

shorowit,

Thank you so much, now all make sense.

Best regards,
