U-Value Tool



The U-Value tool allows you:

to prompt the U-Value for any given construction section

to calculate Equivalent U-Values of constructions with periodic thermal bridges

to calculate Frame U-Values according to EN ISO 10077-2 standard

to calculate Joint UTJ-Values of frame constructions according to EN ISO 12631

to calculate Frame Ufr-and Ueg-Values of frame constructions according to ISO 15099

to calculate Roller Shutter Box Usb-Values according to EN ISO 10077-2

and to label them in the reports.

How do I activate it?

The U-Value tool can be activated with the command U-Value in the menu Results or by clicking on the icon in the Toolbox flyout. Then you have to define the U-value kind in the tool properties (cf. figure 1):

Parallel Layers

Equivalent U-Value

Frame Uf-Value

Joint UTJ-Value

Frame Ufr Ueg-Value

Roller Shutter Box Usb-Value

How do I use it?

The use, meaningful application, physical explanations and limitations of the calculation kinds are described in different chapters:

Defining Styles

The presentation of an U-value object can be defined in the Style list in the U-Value tool properties (see figure 1). The list shows all styles for U-value objects that have previously been determined in the Styles flyout.

A new U-value object will always be created with the styles currently marked in the Style drop down list. You can either change the selection of the styles in the Styles flyout or in the Style drop down list in the U-Value tool properties.

The styles can also be adjusted afterwards by using the Assign Properties tool or by using the Drag&Drop function (see lesson 1).

This tool can only be used on the report page and only if result objects of a previously calculated model are present.
