The Psi-Value Calculator is used for rapid calculation of the thermal heat bridge "correction" factors Psi (Ψ) resulting from the input of
U-values and lengths specific to the building component concerned and its
coefficient L2D as calculated within appropriate two dimensional,
thermal heat bridge simulation
Calculating U-values needed is supported by the
integrated within this Psi-Value calculation tool.
Up to two U-Value and Length pairs can be entered. The formulas used for this calculation are defined in the EN ISO 10211.
Remark: Obtaining coupling coefficient L2D can be accomplished with
appropriate two dimensional, stationary, thermal heat bridge simulation software. For
example AnTherm provides class A precision
method of such calculation.
