Buildings.HeatTransfer.Windows.Functions.BaseClasses.partialGlassRadiation

Partial function for glass radiation property

Information

This is a partial function that is used to implement the radiation functions for windows. It defines basic input variables and constants.

Extends from Buildings.HeatTransfer.Windows.Functions.BaseClasses.partialSingleGlassRadiation (Partial function for single glass radiation property).

Inputs

Type	Name	Description
Integer	N	Number of glass layers
Integer	NSta	Number of window states for electrochromic windows (set to 1 for regular windows)
Integer	HEM	Index of hemispherical integration

Modelica definition
