.Buildings.ThermalZones.Detailed.BaseClasses.ExteriorBoundaryConditionsWithWindow

Information

This model computes the boundary conditions for the outside-facing surface of opaque constructions and of windows.

The model computes the infrared, solar, and convective heat exchange between these surfaces and the exterior temperature and the sky temperature. Input into this model are weather data that may be obtained from Buildings.BoundaryConditions.WeatherData.

This model extends Buildings.ThermalZones.Detailed.BaseClasses.ExteriorBoundaryConditions, which models the boundary conditions for the opaque constructions, and then implements the boundary condition for windows by using the model Buildings.HeatTransfer.Windows.ExteriorHeatTransfer.

Revisions

• November 9, 2021, by Michael Wetter:
  Corrected use of each keyword.
  This is for issue 2731.
• September 16, 2021, by Michael Wetter:
  Removed parameter lat because the latitude is now obtained from the weather data bus.
  This is for IBPSA, #1477.
• January 12, 2019, by Michael Wetter:
  Added missing each.
• March 13, 2015, by Michael Wetter:
  Changed model to avoid a translation error in OpenModelica if the connector is conditionally removed.
• October 28, 2014, by Michael Wetter:
  Replaced final parameter Boolean haveShade=haveExteriorShade[1] or haveInteriorShade[1] with a test for all elements of the vector. This was not possible in earlier versions of Dymola, but now works.
• October 20, 2014, by Michael Wetter:
  Conditionally removed shade if not present. This is for issue 234.
• February 8 2012, by Michael Wetter:
  Changed model to use new implementation of Buildings.HeatTransfer.Radiosity.OutdoorRadiosity. This change leads to the use of the same equations for the radiative heat transfer between window and ambient as is used for the opaque constructions.
• August 9, 2011, by Michael Wetter:
  Fixed bug that caused too high a surface temperature of the window frame. The previous version did not compute the infrared radiation exchange between the window frame and the sky. This has been corrected by adding the instance skyRadExcWin and adding the parameter absIRFra. This closes ticket issue 36.
• November 23, 2010, by Michael Wetter:
  First implementation.
