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 |
type SurfaceRoughness = enumeration(VeryRough "Very rough", Rough "Rough", Medium "Medium rough", MediumSmooth "Medium smooth", Smooth "Smooth", VerySmooth "Very smooth");
