functionglassAbsExteriorIrradiationExteriorShading
Angular and hemispherical absorptance of each glass pane for exterior irradiation with exterior shading
Extends from Buildings.HeatTransfer.Windows.Functions.BaseClasses.partialWindowShadingRadiation (Partial function for window radiation property with shading device).
Information
This function computes angular and hemispherical absorptance of each glass pane for exterior irradiation with exterior shading.
Pane 1 is facing outside and pane N is facing the room.
Inputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real[N,HEM,NSta] | absExtIrrNoSha | Angular and hemispherical absorptance of each glass pane for exterior irradiation without shading | |
| Real[3,N,N,HEM,NSta] | traRef (from partialWindowShadingRadiation) | Transmittance and reflectance with exterior irradiation and no shading | |
| Real[2,2] | traRefShaDev (from partialWindowShadingRadiation) | Transmittance and reflectance of shading device | |
| Integer | N (from partialGlassRadiation) | Number of glass layers | |
| Integer | NSta (from partialGlassRadiation) | Number of window states for electrochromic windows (set to 1 for regular windows) | |
| Integer | HEM (from partialSingleGlassRadiation) | Index of hemispherical integration |
Outputs
