.Buildings.HeatTransfer.Windows.BaseClasses.Examples.SideFins

Information

This example uses the basic side fins model with solar angles as input and calculates the fraction of total window area that is exposed to the sun. For a detailed description of the solar angles used in the model, see to documentation in the package Buildings.BoundaryConditions.SolarGeometry. For a detail description of side fin model, see Buildings.HeatTransfer.Windows.BaseClasses.SideFins. The required data for the solar angle calculations are obtained from the weather data.

• 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

Revisions

• September 16, 2021, by Michael Wetter:
  Removed assignment of parameter lat as this is now obtained from the weather data reader.
  This is for IBPSA, #1477.
• July 5, 2012, by Michael Wetter:
  Changed definitions of side fin height h to be measured from the top of the window.
