Hi @kerowe
I did a test with your system, it has nothing wrong with it in terms of running the simulation.
So the problem is from the ReadEPResults component. I wrote a test component to read the csv file, and it proves the csv is fine. I think it has something to do with the ReadEPResults component. Not sure if @chris can provide some insights about this.
But generally speaking in a multizone energy model with systems, you won’t be able to get zone level cooling and heating energy, because plantloops provides heating and cooling via water, it is not easy to quickly identify how much goes to each zone.
If you need the total energy and peak load, I have a workflow to extract those data from html file:
