modelOverhang
Test model for the overhang
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example uses the basic overhang model with solar angles as input and calculates the fraction of total window area that is exposed to the sun. For a detail description of the solar angles used in the model, see Buildings.BoundaryConditions.SolarGeometry. For a detailed description of the overhang block, see Buildings.HeatTransfer.Windows.BaseClasses.Overhang. The required data for the solar angle calculations is obtained from weather data.
Solar angles used in this model are:- Buildings.BoundaryConditions.SolarGeometry.ZenithAngle: Angle between sun ray and normal to horizontal surface
- Buildings.BoundaryConditions.SolarGeometry.IncidenceAngle: Solar incidence angle on a tilted surface
- Buildings.BoundaryConditions.SolarGeometry.BaseClasses.AltitudeAngle: Angle between Sun ray and horizontal surface
- Buildings.BoundaryConditions.SolarGeometry.BaseClasses.WallSolarAzimuth: Angle measured in horizontal plane between projection of sun's rays and normal to vertical surface
The values of the parameters of the overhang model have been set in such a way that the overhang in non-symmetric with respect to the window center-line.

Removed assignment of parameterlatas this is now obtained from the weather data reader.
This is for IBPSA, #1477. -
