Details on Composed Component
Information about the Composed Component section in the Master Tables workspace.
Components such as walls and floors consist of different layers. You can compile the layer structure of such components in this area by defining the individual layers and their material properties. You can then assign the component with the layer structure to room components so that its structure is taken into account in load calculations. The values resulting from the layer structure are displayed in the lower area on the Results tab.
You are here:
No.
Defines the number of the component. The number is used to identify the component and also for sorting in the tree structure. All supplied components are provided with numbers. Each number may only appear once in the Components, U-Value Calculation section of the Master Tables. When new components are created, the next free number is selected so that any gaps in the numbering of existing components are automatically closed. The variable used by default in the Short Description field ($NR2) means that the number is automatically transferred to the short description.
Short Desc.
Defines the short description of the component that is displayed in front of the component in the Master Tables. By default, a C for component followed by a variable ($NR2) is stored in this field. This variable automatically transfers the number of the component to the short description. By entering any combination of characters before the variable, you can customize the short description of the component. If necessary, replace $NR2 with $NR3 to create three-digit numbering. If necessary, remove the variable to manually assign a short description to the component without adopting the number.
Description: Defines the Name of the component.
Use Predefined Values
Enabled: The U-Value input field is activated and you can enter a U-value for the component.
Disabled: To define a layered component, the table and the graphic layer editor are displayed.
U-Value Correction
If the U-value of a component is to be adjusted, e.g. due to facade fasteners, you can enter the corresponding correction supplement here. The supplement is taken into account in the heat load calculation if the component is assigned to a room component, provided the selected calculation method supports U-value corrections.

Table
Enables the definition of the layer structure of a component in a table. The first layer is always inside or on top. You can only adjust the Type and the Thickness or Width of a layer via the table.
| Column | Description |
|---|---|
| Type | Specifies the type of layer. You can choose between Simple (continuous layer) and Composite (composite - repeating elements, such as beams in a wooden beam ceiling). |
| Building material No. | Determines the building material of the layer based on its number. If known, the material number can be entered directly. You can also enter the desired building material as a search term in the field and press Enter to display the hit list in the Building Material List dialog. Clicking |
| Layer name | Defines the name of the layer. |
| Thickness, Width, Height | Determines the thickness and width or height of the layer. Once a layer is composed, the distance at which a building material repeats is determined by the width of the building materials in between. |
| Thermal conductivity Lambda | Displays the thermal conductivity of the building material of the layer, which is stored in the corresponding Table of Building Materials. The heat conductivity of a building material describes how well it conducts heat. This value is required for calculating the U-value. |
| Consistency | Displays the material density of the building material of the layer, which is stored in the corresponding Table of Building Materials. The density of a building material is used to calculate the thermal storage capacity in the dynamic cooling load calculation. |
| Specific heat capacity | Shows the specific thermal conductivity of the building material of the layer, which is stored in the corresponding Table of Building Materials. The specific heat capacity describes the ability of a substance to store thermal energy. This value is used to calculate the thermal storage capacity in the dynamic cooling load calculation. |
also opens the Graphical Layer Editor
: Enlarges or reduces the display of the current layer structure.
: Opens the Building Material List dialog to select a material. You can then assign the selected building material to a layer in the graphical layer editor.
: Enables the insertion of neutral layers with a subsequent click in the graphical layer editor.
: Opens the Select Air Layer Type dialog, where you can choose between a static or weakly or strongly circulating air layer and specify the layer thickness. You can then click to insert the air layer in the graphical layer editor.
: Removes the currently selected layer.
: Reverses the layer order.
Example Rsi/Rse: Allows you to enter heat transfer resistances with which you can test the results of U-value calculations for a specific installation situation. The finally used heat transmission resistances depend on the calculation module and on the installation situation of the component. They are only determined when they are actually used.
Vertical Layer Structure
Enabled: Inserts the selected building materials vertically as layers from left to right.
Disabled: Inserts the selected building materials horizontally as layers from top to bottom.
