# .BuildSysPro.IBPSA.ThermalZones.ReducedOrder.Examples.SimpleRoomFourElements

Illustrates the use of a thermal zone with four heat conduction elements

## Information

This example shows the application of IBPSA.ThermalZones.ReducedOrder.RC.FourElements in combination with IBPSA.ThermalZones.ReducedOrder.EquivalentAirTemperature.VDI6007WithWindow and IBPSA.ThermalZones.ReducedOrder.SolarGain.CorrectionGDoublePane. Solar radiation on tilted surface is calculated using models of IBPSA. The thermal zone is a simple room defined in Guideline VDI 6007 Part 1 (VDI, 2012). All models, parameters and inputs except sunblinds, separate handling of heat transfer through windows, an extra wall element for ground floor (with additional area), an extra wall element for roof (with additional area) and solar radiation are similar to the ones defined for the guideline's test room. For solar radiation, the example relies on the standard weather file in IBPSA.

The idea of the example is to show a typical application of all sub-models and to use the example in unit tests. The results are reasonable, but not related to any real use case or measurement data.

## Revisions

- September 6, 2021, by Ettore Zanetti:
  Changed `lat` from being a parameter to an input from weather bus.
  This is for IBPSA, #1477.
- July 11, 2019, by Katharina Brinkmann:
  Renamed `alphaWall` to `hConWall`, `alphaRoof` to `hConRoof`, `alphaWin` to `hConWin`
- April 27, 2016, by Michael Wetter:
  Removed call to `Modelica.Utilities.Files.loadResource` as this did not work for the regression tests.
- February 25, 2016, by Moritz Lauster:
  Implemented.
