[TRNSYS-users] Type 35 window Beam Radiation Output

[Diego A. Arias]

Dear Rémi,

Thank you very much for sending us this email. There is a problem with 
the update of the outputs when the radiation is zero. This problem will 
be solved in the next release.
Best regards,

Diego

The output for the Beam Energy to Room (4) gets stuck at the last value where the input solar radiation was non-zero.  This is not a problem for East and North facing windows as the Beam radition is usually 0 before incident solar radiation becomes 0, and therefore gets stuck at 0 as it should during the night.  However, for South and West facing windows, the output beam radiation rarely goes to zero over the course of the year because of this problem (day and night).
>I don't know if this will cause any problems with my results as this data is fed into my Type 19 window model.  Since solar radiation incident on the window is 0, the program should realize that beam radiation by default will be 0.  But I don't know if that is the case or not.
