Equivalent U-value

, ,
Equivalent U-Values are usefully calculated for constructions with periodically appearing thermal bridges (e.g. ceiling construction with rafter). The equivalent U-value considers already the influence of these thermal bridges.

Summary

An equivalent U-value is defined using the U-Value tool Equivalent U-Value by applying with 3 mouse clicks. The first two points define the surface line, through which the effective heat flow should be calculated.  The third point defines the  position of the dimension line. The points are captured if the snap functions  are active (Grid , Guidelines and Objects , cf. menu Arrange).

You can adjust the properties of the U-value calculaion in the Properties flyout.
