Glazing U-Value: This measures how effective is your glazing material as an insulator. Lower U-value means higher insulation which ultimately leads to energy savings.

Glazing SHGC: Solar Heat Gain Coefficient for the glass. The higher the SHGC value more heat the space will receive. SHGC value varies from 0 to 1.

Glazing area values will be populated automatically if the Revit, Rhino/Grasshopper and SketchUp plugin is used. These values can be edited manually as well.

The red highlighted button can be used to switch the input mode from Area(ft2) to Percentage(%) for glazing.
