PsiValue CalculatorThe PsiValue Calculator is used for rapid calculation of the thermal heat bridge "correction" factors Psi (Ψ) resulting from the input of Uvalues and lengths specific to the building component concerned and its thermal coupling coefficient L^{2D} as calculated within appropriate two dimensional, stationary, thermal heat bridge simulation software. Calculating Uvalues needed is supported by the Uvalue Calculator integrated within this PsiValue calculation tool.
Up to two UValue 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. Calculating UValues with UValue CalculatorTo calculate respective UValue with an integrated UValue Calculator, press the button "Layered Construct", build or load the layered construct within the UValue Calculator which is shown thereafter and confirm the calculated result by pressing the Okbutton therein. The actual data of a layered construct can be changed at any time by pressing the button "Layered Construct" again and editing the data within the UValue Calculator shown thereafter. Remark: The actual data of a layered construct is retained until the application is exited. To save the data of each respective layered construct use the "Save" function within the UValue Calculator. Remark: You can drag & drop any layered construct (as it is available from a UValue Calculator if it is run separately) onto the one of UValue / Length blocks in this window also. Remark: To override the value manually uncheck the checkmark left to the button "Layered Construct". Remark: If no data of a layered construct has been applied yet, the checkmark left to the button "Layered Construct" is shown greyed. Entering the Thermal Coupling Coefficient L^{2D} obtained from AnThermAnTherm's "Coupling Coefficients Report" provides the matrix of thermal coupling coefficients resulting from stationary simulation of respective modelled construction. As AnTherm displays both, the interior and exterior calculated values for precision validation purposes, you can either use any one of the two or apply the mean value of both for example, provided that precision criteria is satisfied. Important: UValues and lengths used for the PsiValue calculation must correspond to the coupling coefficient of the modelled component in the manner defined within EN ISO 10211.
