With this routine you can compute the mean thermal transmission coefficient for a window or a facade.

In the dialog box you can enter a comment or a title for the computation in the input line at the top. The title can be saved in various languages. To do this, select the required language from the list and enter the text in the chosen language.

You can define the parameters for the respective position in the input fields. The following values can be entered:

With the Edit button you transfer the details of the component, which is marked in the table Facade components, to the input fields. You can only change single parameters in the input fields
With the Insert button the details from the input fields are transferred into the table Facade components. The details are always inserted below the marked line.
With the button Replace the marked position in the table is overwritten with the details from the input fields.
If you press the button Remove, the marked position is deleted from the table.
If you click Sort, the positions are sorted.

Here the entered elements or facade sections are displayed with their values. Mark a line with the mouse if you want to change it (Replace).

Here the computed results for the area (Acw in m²) are computed and displayed for the heat transfer coefficient (Ucw in W/m²K).

When the option Insert text is activated, a results text is inserted into the drawing on clicking OK. An input request in the command line follows. You can define the text height for the table in the field Text height. With the button Default the default text height (current height of dimension figures) is set. With the pick lists Text style header and Table you define the text style for the corresponding table elements.
