Hello, using EnergyPlus V8.90. It seems there are little/none discussion about the lbl Window5 data in IDF file here. I have to run a model that was given to me in which they modified the window only. They have the window data input as a Window5 data file.

I made sure the Window5DataFile.dat is in the correct location (by default, the EnergyPlus.exe directory)

The dat. file has two window construction types, "Dual Tint" and "1/4 Clear". It is referred to in the IDF file. image description

During the first pass, 1/4 clear is not recognized. But it was only used in 1 surface, so I deleted it from constructions and changed all fenestration surface to use the "Dual Tint" construction type. image description

Then for the second pass, the simulation is always stuck at this point (and sometimes crashes): image description

I have tried a number of methods, including using the newest version of WINDOW to generate the same file to use, but it did not work and I am stuck... how to solve this?

The preferred method for exporting from Window is to generate a "Report" for a specific window and select Report Type "EnergyPlus IDF File". See the EnergyPlus Tips and Tricks document section titled "Getting data from WINDOW program". This generates idf objects which can be pasted directly into the idf file.

That said, the old Window5 data file shouldstill work. Please post a link here to the problem files (idf and window5 data file) or attach to an email to the EnergyPlus helpdesk at Example file 1ZoneUncontrolled_win_1.idf uses Construction:WindowDataFile with \datasets\Window5DataFile.dat, but that file was generated long ago, not from a current version of Window.

This is resolved.. turns out it's an extra space after the word "1/4 Clear". Everything runs. Used E+ V8.6 to run the model instead.
