Energy Plus IDF files
 

The ZIP file linked above (IGDB-59-IDF.zip, which is shown when you have logged in to your account) with the Energy Plus IDF files has the following files in it:

  • IGDB-59-Material.IDF
    This file contains an Energy Plus "WindowMaterial:Glazing" definition, which references the spectral data from the 2nd file, for each glass layer in the IGDB
  • IGDB-59-SpectralData.IDF
    This file contains an Energy Plus "MaterialProperty:GlazingSpectralData" definition (referenced from the Material) for each glass layer in the IGDB
    This file does not have averaged spectral data, only the detailed spectral data by wavelength.

You need to have both the WindowMaterial:Glazing and the MaterialProperty:GlazingSpectralData definition for each glass layer used in an Energy Plus input file.
