## Buildings.Types.Azimuth

List of possible constant values for surface azimuth

### Information

Collection of constant values to define the azimuth of a surface.
For example, if an exterior wall is South oriented, i.e., its outside-facing
surface is towards South, use
`Buildings.Types.Azimuth.S`

.

See also Buildings.BoundaryConditions.UsersGuide for explanations of the azimuth.

Extends from Modelica.Icons.TypesPackage (Icon for packages containing type definitions).

### Package Content

Name | Description |
---|---|

S=0 | Azimuth for an exterior wall whose outer surface faces south |

SW=+Modelica.Constants.pi/4 | Azimuth for an exterior wall whose outer surface faces south-west |

W=+Modelica.Constants.pi/2 | Azimuth for an exterior wall whose outer surface faces west |

NW=+Modelica.Constants.pi*3/4 | Azimuth for an exterior wall whose outer surface faces north-west |

N=Modelica.Constants.pi | Azimuth for an exterior wall whose outer surface faces north |

NE=-Modelica.Constants.pi*3/4 | Azimuth for an exterior wall whose outer surface faces north-east |

E=-Modelica.Constants.pi/2 | Azimuth for an exterior wall whose outer surface faces east |

SE=-Modelica.Constants.pi/4 | Azimuth for an exterior wall whose outer surface faces south-east |
