Complex Glazing Features for Berkeley Lab WINDOW6

Last Updated: 

Tuesday, September 5, 2017

Software/Versions Affected:

• WINDOW›6

The Research Version of Berkeley Lab WINDOW 6 has the following modeling capabilities.

Shading Layer Library

A Shading Layer Library has been added to define shading systems, such as venetian blinds and diffusing layers, which can then be added as layers in the Glazing System Library.

Shade Material Library

A Shade Material Library has been added to define materials to be used in the Shading Layer Library. Properties defined in this library include shade material reflectance and absorptance (in the solar, visible and IR wavelengths ranges), as well as the conductivity of the material.

Glazing System Library

In the “Layers” section of the Glazing System definition, it is now possible to specify either a glass layer or a shading layer. The shading system is chosen from the Shading Layer Library.

Glass Library

It is now possible to define a diffusing layer in the Glass Library, for use in the definition of complex glazing systems.

Calculation Results

The program now produces detailed “matrix” calculation for complex glazing systems. These results consist of one file that contains a large amount of data.

An Excel spreadsheet has been developed  to view these results outside the program.

Program Settings

Preferences:  A Matrix Calculation method option has been added for the complex glazing system calculations, which is the method that calculates the angular effects (both optical and thermal) of venetian blinds.
