Hi,

I'm running into some errors in trying to run an EnergyPlus simulation through EPPY. I am working on a Windows OS. To give a simple example of the error I am trying to run the '1ZoneUncontrolled.idf' with EnergyPlus 8.5 from the E+ examples with an EPW for Amsterdam (renamed 'someWeather.epw' here).

When I run the following python code (all these files are containted within the current 'C:\Z_TestEPPY' directory):

# Import libraries
import eppy
import sys
import os
from eppy.modeleditor import IDF

iddfile = "Energy+V8_5_0.idd"
IDF.setiddname(iddfile)

idfname = '1ZoneUncontrolled.idf'
epwfile = 'someWeather.epw'

Idf = IDF(idfname, epwfile)
Idf.run()

I get the following errors:

ERROR: Could not find input data dictionary: C:\Users\20171493\AppData\Local\Temp\tmp79zt77cw\Energy+V8_5_0.idd.
Type 'energyplus --help' for usage.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    raise EnergyPlusRunError(message)
eppy.runner.run_functions.EnergyPlusRunError:

Contents of EnergyPlus error file at C:\Z_TestEPPY\eplusout.err
<File not found>

I run into this error regardless of the directory, idf or EnergyPlus version that I use. I noted that in the line 'C:/EnergyPlusV8-5-0\e' in the error message there is an inconsistency in the path directory seperators where C:/ does not have an escape character before it. Also the in.idf file does not get created.

Here you can find a link to all the files that I am using in this example.

Kind regards,

Samuel

Yes; that worked! The problem also appeared to be caused by the IDF name starting with a number. When I used the full

I am trying to model 12.7 cm wide vertical blinds using WindowMaterial:Blind:EquivalentLayer. When I do so I get the following errors:

* Severe * Out of range value Numeric Field#1 (Slat Width), value=0.12700, range={>0 and <=0.025}, in WINDOWMATERIAL:BLIND:EQUIVALENTLAYER=WMTEUQL_BLND_KINDV_RF80_T02_A18_RB45 * Severe * Out of range value Numeric Field#2 (Slat Separation), value=0.12700, range={>0 and <=0.025}, in WINDOWMATERIAL:BLIND:EQUIVALENTLAYER=WMTEUQL_BLND_KINDV_RF80_T02_A18

The input should be in meters. It seems a bit strange that the slat width would be limited to a maximum of 2.5 cm. Wider products are quite common and for vertical blind a slat width as small as 2.5 cm doesn't exist. The input output reference also state that 2.54 cm should be the default value.

I am using EP 8.5. I have also tried updating to 9.0 but this still gave the same error. My WindowMaterial:Blind:EquivalentLayer object: (I am aware I am omitting visible properties. I am not interested in these and the exmple IDF shows they are not required)
