Psi-Values with 1 Component will be usefully calculated for constructions where 2 components are connected with the same U-value or where a construction is interrupted by a single component (e.g. mullion of a curtain wall, wall ceiling junction).

Psi-value 1 Construction
Summary
•A Psi-value with 1 component is defined using the Psi-Value tool 1 Construction by applying 2 mouse clicks. The two points define the surface line, through which the effective heat flow should be calculated counterclockwise. The points are captured if the snap functions are active (Grid 
, Guidelines 
and Objects 
, cf. menu Arrange).
•You can adjust the properties of the Psi-value calculation in the Properties flyout.
