<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:

</p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'>In TRNSYS 17’s manual, it is specified that under the standard
mode for beam radiation distribution calculation, if the GEOSURF values of all surfaces
of a zone are all set to 0, then “the direct radiation is distributed the
same way as the diffuse radiation (by “absorptance” weighted area
ratios)”.<o:p></o:p></span></font>

</p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'>But let’s suppose that I run a simulation under the detailed mode
for diffuse radiation distribution and under the standard mode for beam
radiation distribution with geosurf all set to 0. Does it imply that that on
one hand the Gebhart method will be applied for the diffuse part of the
entering solar radiation, and that on the other hand the weighted area ratios
method will be applied for the direct part? Or will the total entering solar
radiation be considered as 100% diffuse and in that case only the Gebhart
method will be applied for calculating the distribution?<o:p></o:p></span></font>
