Hi,

I have run into a problem with E+ recently when trying to model a CCF(closed cavity facade) with blinds. I found out that I can only put blinds only between the inner two glass layers for (between glass shade/blind).

I tried to use WINDOWS to create IDF file but WINDOW doesn't allow to export IDF file with blinds.

Is there any other way around this?

@isac_93 it doesn't look like your image attached correctly the first time -- could you please try again?

Also, are the blinds part of a second skin (e.g., outdoor hallway has an exterior wall enclosing a room as well as another wall) or part of a window construction (e.g., layers of glass separated by gas)?

Please see the image below for the build-up. The blinds are in the first cavity (considering from outdoors) so it goes like this: Glass - Blinds - Solar Control Glass - Argon - Glass

@isac_93 just to clarify, you want to locate the blinds where "Shade 2" is located in your image? In between "Glass 1" and "Glass 3"?

Yes, that is correct.

When exporting from WINDOW, did you select this option: image description

Aha I think this works. Thanks. I selected the "Energy Plus IDF File" and not the BSDF one.

Thank you very much.
