If so then what I would suggest you do is to define your same vertical surfaces in Type16 and then run your measured global horizontal through it. Type16 will give you an estimate of how the global breaks up into beam and diffuse not only for the horizontal but also for the vertical surfaces. I would then compute the ratios of beam to global and diffuse to global that Type16 gives you for each surface and then use those ratios multiplied by your actual measurements to come up with the components that Type56 wants. <o:p></o:p></p><p>kind regards,<o:p></o:p></p><p> david<o:p></o:p></p><p> <o:p></o:p></p><div><p class=MsoNormal>On 06/17/2021 04:15, Freppel, Wirich via TRNSYS-users wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Dear Trnsys users,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I measured global solar radiation on vertical surfaces (one for each orientation) using a pyranometer.
