The error message is pretty transparent: you have some Coil:Heating:Water in your model that aren't connected to any air loops (orphaned) and thus EnergyPlus is issuing a fatal error. One is called "COIL HEATING WATER 1".

Remove them. If you can't find them in the OS App, you can use scripting.

See How do you fix orphaned objects in OpenStudio and especially the BCL measure that you can download and run on your model.

Your model is full of trash. Just use and adapt the code from Andrew https://unmethours.com/question/928/h...

i lost the errors after i removed the systems in this tap but then i'm getting zero cooling and heating loads so probably with enabling the ideal loads i also need to use a template for HVAC system? but when i do that i get errors and the simulation stops

You're polluting the comment section a bit here, and your images are way oversized.

Also, you don't have any problems, you're just looking in the wrong column, make a habit of looking at the I/O reference guide before asking for help. see here. "The energy required to condition the supply air is metered and reported as DistrictHeating and DistrictCooling."

Understood, thank you :)
