Information

Function inspired by calculation of overhang effects described in ISO 13791 standard

Hypothesis and equations

Bibliography

ISO 13791 standard

Instructions for use

none

Known limits / Use precautions

This function should only be called for an absolute value of Phi strictly lower than 90°, corresponding to the sun that reaches the window plane (abs(azimut-AzimutSoleil) ‹ 90).
