Hi everyone, in EnergyPlus I simply want to sum up the cooling load of each zone, so I do not need to do that via python. However, when I was checking the Variable file, I found the calculation results look wrong.

Here are some screenshots of how I setup variables. Since I am new here, I gonna use links. Sorry for the inconvenience. https://ibb.co/HPyh9cL https://ibb.co/pXFy0fg https://ibb.co/Ry8zZCy https://ibb.co/SyQtVn3

And here is the result in Variable file, you can clearly find that the Sumup(1st row) does not equal to the sum up of cooling load in 2 rooms (2nd and 3rd rows).

I have tried several different 'EnergyPlus Model Calling Point', but the error still exists.

Thanks in advance! https://ibb.co/ryTgsCB
