A couple of things about window in OS/E+:

  • A construction just shows you what materials make it up, you need to go to the materials to see their properties.
  • In your case, the fixed window material is a simple glazing system window material. This type of material just has inputs for U-Factor, SHGC, and VT (note that this is for the window assembly including the frame, not the center of glass window values).
  • If you want to actually build the glazing type you need to build a window with glazing materials and layers, glass + air + glass for a double pane. Note that if you are doing these then you need to have frame and divider objects for your windows as well. See here

now i know i've the U-Factor, SHGC, and VT but yet the type of glazing type, thickness is unknown! i'm doing a research paper on the impact of changing WWR, Blind legnth and Blind tilt angle on 50 models in 3 cities, i didn't design an actual window layers cause i didn't think i need to change the defaults since my point is making the comparison between those cases based on WWR and Blinds characteristics. so all i need now is to add to my paper the glazing default type " Single, Double " and thickness " 6 mm " For example and the deadline is by the end of this week!

Further to @TaylorRoberts answer, you can set thickness of the glass in the material tab; you can set the thickness of the wall/sill/shading elements with a Window:FrameAndDivider object.

You can also use the Window and/or Optics programs to exercise total control of these elements and roll them up into a single element for inclusion in an OpenStudio model.

According to your additional comments, you don't know the thickness of the glazing, but you do know the SHGC/VLT/U info, and are merely evaluating the changes to window area and shading configuration. All the more reason to use the "Simple Glazing System" material type IMO; that material only requires these three inputs to describe the glazing performance. Then you can use measures to vary the WWR and shading configurations. Does this make sense?
