Issues when running E+residential building prototype model in python script.

[XiongbaXu]

Issue overview

I used the Eppy library to run simulations in Python. However, I encountered some problems. When I use Eppy to simulate with the building type 'US+SF+CZ5A+elecres+unheatedbsmt+IECC_2021' (https://www.energycodes.gov/prototype-building-models), it works fine. But when I try to simulate with building types 'US+SF+CZ5A+elecres+heatedbsmt+IECC_2021' and 'US+SF+CZ5A+elecres+slab+IECC_2021', I get errors.
"EnergyPlusRunError:

Here is my python script

import os
from eppy.modeleditor import IDF

def make_eplaunch_options(idf):
    """Make options for run, so that it runs like EPLaunch on Windows"""
    idfversion = idf.idfobjects['version'][0].Version_Identifier.split('.')
    idfversion.extend([0] * (3 - len(idfversion)))
    idfversionstr = '-'.join([str(item) for item in idfversion])
    fname = idf.idfname
    options = {
        'output_prefix': os.path.basename(fname).split('.')[0],
        'output_suffix': 'C',
        'output_directory': os.path.dirname(fname),
        'readvars': True,
        'expandobjects': True
    }
    return options

def main():
    iddfile = r"C:\EnergyPlusV24-1-0\Energy+.idd" 
    IDF.setiddname(iddfile)
    
    epwfile = r"C:\Users\Desktop\test1\ep_epw.epw"  

    idfname = r"C:\Users\Desktop\test1\US+SF+CZ5A+elecres+heatedbsmt+IECC_2021.idf"  
    idf = IDF(idfname, epwfile)
    theoptions = make_eplaunch_options(idf)
    idf.run(**theoptions)

This issue is quite confusing, as it's got nothing to do with python.

You downloaded

https://www.energycodes.gov/sites/default/files/2021-05/resstd_CZ5A_IECC_2021.zip

and the weather file: https://www.energycodes.gov/sites/default/files/2021-05/USA_NY_Buffalo.Niagara.Intl_.AP_.725280_TMY3.epw

The files in resstd_CZ5A_IECC_2021.zip are at version 9.5. So you must use IDFVersionUpdater to transition them to 24.1.0 prior to running them with 24.1.0.

And it works just fine.

Here is the IDF in question transitioned to 24.1.0
