The GEOSURF value in each surface of a zone is the fraction of
beam radiation that strikes that surface. It can be a bit tricky to
calculate the fraction of beam solar radiation that strikes a given
surface (such as your adjacent wall) but usually you can use some basic
geometry equations to get an estimate of the amount of solar radiation
striking that surface. When start to specify GEOSURF values for surfaces
in a zone, you must make sure that the sum of all the GEOSURF values for
that zone is always 1. If not, Type56 will generate an error.<br>
Kind regards,<br>

We are modelling a building with several thermal zones. We have a thermal
zone which does not have any contact with outside. In this case there is
a wall adjacent to another zone, and this wall receives beam radiation
through of the windows of another thermal zone which is external.<br>
<br>
Our doubt is that we do not know how to take into account the beam
radiation in the internal wall which is made with windows as well.<br>
<br>
We have simulated the building changing the orientation of the windows in
this internal wall to know if radiation is changing as well, but the
results are the same.<br>
<br>
The “Q sens” is the same in this internal zone changing the orientation
of their windows so we do not know how to take into account the
radiation.<br>
<br>
Thank you in advance for any comment<br>
