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.

Solar angles used in this model are:

    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.
