hi.@chris
After the Window Construction Dynamic component was updated to version LBT 1.9, it is still unavailable in the latest version as of today. I am certain that this component was able to function normally within the expected range in version LBT 1.8.
I have created a simple case for you to test and attempt to reproduce.
In any case, the program’s feedback is exactly the same as this.
Program Version,EnergyPlus, Version 25.1.0-1c11a3d85f, YMD=2026.01.30 13:13,
** Severe ** <root>[Construction][Generic Construction] - Missing required property 'outside_layer'.
** 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=<root>[Construction][Generic Construction] - Missing required property 'outside_layer'.
************* 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. 0 Warning; 1 Severe Errors; Elapsed Time=00hr 00min 0.08sec
Runtime error (PythonException): ** Fatal ** Errors occurred on processing input file. Preceding condition(s) cause termination.
Traceback:
line 325, in script
I think this might be a bug that no one has pointed out so far.
