## Buildings.HeatTransfer.Types.ExteriorConvection

Enumeration defining the convective heat transfer model for exterior surfaces

### Information

This enumeration is used to set the function that is used to compute the convective heat transfer coefficient for exterior (outside-side facing) surfaces.

### Modelica definition

## Buildings.HeatTransfer.Types.InteriorConvection

Enumeration defining the convective heat transfer model for interior surfaces

### Information

This enumeration is used to set the function that is used to compute the convective heat transfer coefficient for interior (room-side facing) surfaces.

## Buildings.HeatTransfer.Types.SurfaceRoughness

Enumeration defining the surface roughness

### Information

This enumeration is used to define the surface roughness which may be used to compute the convective heat transfer coefficients of building construction.

The surface roughness will be used to compute the wind-driven convective heat transfer coefficient in Buildings.HeatTransfer.Convection.Exterior. The possible surface roughness are

Roughness index | Example material |
---|---|

VeryRough | Stucco |

Rough | Brick |

MediumRough | Concrete |

MediumSmooth | Clear pine |

Smooth | Smooth plaster |

VerySmooth | Glass |
