Hi there,

I have a challenge in running a simulation for a super-duper house for the HVAC system.

Here is the eplusout.err details:

Program Version,EnergyPlus, Version 23.2.0-7636e6b3e9, YMD=2024.06.02 12:58,
** Warning ** Version: in IDF="23.1" not the same as expected="23.2"
** Severe  ** HVACTemplate:* objects found. These objects are not supported directly by EnergyPlus.
**   ~~~   ** You must run the ExpandObjects program on this input.
**  Fatal  ** Errors occurred on processing input file. Preceding condition(s) cause termination.
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=HVACTemplate:* objects found. These objects are not supported directly by EnergyPlus.
************* Warning:  Node connection errors not checked - most system input has not been read (see previous warning).
************* Fatal error -- final processing.  Program exited before simulations began.  See previous error messages.
************* EnergyPlus Warmup Error Summary. During Warmup: 0 Warning; 0 Severe Errors.
************* EnergyPlus Sizing Error Summary. During Sizing: 0 Warning; 0 Severe Errors.
************* EnergyPlus Terminated--Fatal Error Detected. 1 Warning; 1 Severe Errors; Elapsed Time=00hr 00min  0.04sec

Could you kindly let me know how I could tackle the challenge?

Thanks very much in advance.

Sincerely, Behnam

I don't know how you are running EnergyPlus, but e.g. you can run the ExpandObjects project using the -x argument when running from the commandline:

energyplus.exe -x file.idf ...
