Software/Versions Affected:

Chromogenic layers (such as electrochromic and thermochromic layers)  are switchable, dynamic coatings on glass or films that have properties that are passively or actively controlled to modulate admission of light and heat. 

The LBNL International Glazing Database (IGDB) contains several chromogenic layers. When the manufacturers submit their data to the IGDB, they submit data for several of the different states of the chromogenic layer. Each of these states is shown as a separate record in the IGDB, even though they are all the same product. Below is an example of how the View electrochromic layers are represented in the IGDB. This is also how the records will look when they are first imported (during the IGDB update process) into the WINDOW Glass Library from the IGDB.

A WINDOW database can be structured so that only one representative record for a chromogenic glazing (usually the "lightest" state) is shown in the WINDOW Glass Library List view, and all the states are then displayed in the Glass Library detail view. 

In order to update the WINDOW Glass Library to have the chromogenic data structured that way, it is necessary to delete the existing single entry chromogenic records, and update a "grouped" set of records from a specially structured WINDOW database. 

Then the data will look like this:

There will be one representative record for the layer in the Glass Library List view

All the records, each representing a different state for the same glazing, will be displayed in the Glass Library Detail view

Steps for updating the WINDOW Glass Library Chromogenic layers

Update the Glass Library to the latest IGDB release

  • Download and Install the latest IGDB release
  • Start WINDOW
  • In the Glass Library List view, click the "Update IGDB" button, which updates all the records in that library to the latest version of the IGDB

Update the Chromogenic Layers in the Glass Library

  • Find the chromogenic layers in the Glass Library
  • If they are shown as individual layers for the same product, delete all the layers
  • Import the same glazing layer from the WINDOW Chromogenics database, and there will be only one record shown in the Glass Layer List view and all the records in the Glass Layer Detail view
  • Repeat these steps for any chromogenic layers in the WINDOW Glass Library that are not "grouped"

    Example: Updating the Kinestral Electrochromic layers (IGDB V 58.0)

    Update the Glass Library to the latest IGDB release

    • Download and install IGDB V 58.0
    • In the WINDOW Glass Library List view, click the "Update IGDB" button, to update all the records in the library to IGDB 58.0
    • After the update, there will be many Kinestral records listed, which together represent two different products

    • Delete those individual records
    • Import the grouped Kinestral records from a special WINDOW Chromogenics database that should be automatically installed with the IGDB install. The file installed is a zip file called

    Which contains two WINDOW databases:

    W-7-5-Chromogenics.mdb (can be used by either WINDOW 7.4 or 7.5)

    W-7-6-Chromogenics.mdb (for use with WINDOW 7.6)

    and located in 

    C:\Users\Public\LBNL\LBNL Shared

    • Import from the appropriate WINDOW database and select the desired records. In this example, one record is shown for each of the Kinestral products, and when they are selected for import, the associated records for each state will also be imported.

    • The Glass Library will now show two Kinestral records in the List View

    • The Glass Library Detail view will show all the records representing the measured states, that will be used in the WINDOW calculations

    The Glass Library Detail View shows all the states that were measured (each column represents an individual record of measured data)
