Reference Commands > W
Function to determine the U-value of a wall, according to its built-up layers.
AutoCAD/BricsCAD
Command line: _WANDDEF
Assistant: | Building physics|
Navigator
All walls in the project are listed here.
By right-clicking on a wall you can:
Component type
Defines the wall type according to the Norm (exterior wall, interior wall, etc.).
e...exterior component
b...interior component
g...component to ground
u...component to unheated
Temperature and relative humidity
These fields are necessary for the graphic display of each wall.
The exterior temperature can be found in the norm.
U-values
U-value according to the layer-composition.
Composite walls can be calculated here.
Layer composition
Defines the material built-up of a wall (exter. -> inter.)
The temperature and water vaporisation (Glaser-diagram) development is shown in the diagram.
By right-clicking on a buit-up layer you can:
Print
To print a calculation form with wall built-ups, temperature and water vaporisation development, select "Print".
