Error when adding hvac system to model

Hi all,

I have a model that runs fine without an HVAC system but when I add even the simplest HVAC system and run a simulation I get 5 errors and the following message in the tree view:

"EnergyPlus Starting

EnergyPlus, Version 8.3.0-6d97d074ea, YMD=2015.11.03 14:43

Processing Data Dictionary

Processing Input File

**FATAL:IP: Errors occurred on processing IDF file. Preceding condition(s) cause termination.

EnergyPlus Run Time=00hr 00min 0.46sec"

I know this is a very generic error but I was hoping someone here might have a few things for me to try. I tried many different settings, made sure everything looks similar to a model with an HVAC system that produces results but could not make it work.

Any help is appreciated.

You mention the tree view, are you using OpenStudio? Have you checked the ERR file for more detail?

Yes I use OpenStudio, sorry I forgot to mention it. I opened the .err file and get a warning, several severe errors and a fatal error. My first error which I think causes all the following ones is this:

* Severe * IP: IDF line~9868 Object=CONTROLLER:MECHANICALVENTILATION, name=CONTROLLER MECHANICAL VENTILATION 1, Required Field=[Zone 1 Name] was blank.

Try adding an Output:Diagnostics object to DisplayAllWarnings, which will add more detail to the ERR file.

Some other thoughts:

  • Check the ERR file for more detail about the error(s)

  • If you're using OpenStudio make sure the model has a weather file (may need to re-select it).
