Glazing Components

Glazing systems are simulated in EnergyPlus according to the ISO 15099 2003 standard.

 

There are 2 ways to enter Glazing component data depending on the Definition method setting:


  1. Material Layers - where the properties of the glazing component is defined in detail through selection of a number of glazing layers (Panes) separated from each other by window gas layers. In this case there are two tabs on the Glazing data dialog:

  2.  

  3. Simple - the glazing properties for the overall glazing system are defined using summary U-value, Solar Heat Gain Coefficient (SHGC) and Visible transmittance (VT) data. This approach is recommended when only manufacturers summary glazing performance data is available or where only whole assembly glazing data is available. If more detailed data on the constituent panes is available then the more accurate Layers method should be used.
