I think you are on the correct path; the "receiver" defined in
Type34 should be for each divided part of the window. Keep in mind
that Type34 is computing a modified amount of solar radiation
falling per unit of receiver area so it is okay for the area of the
receiver and the area of the actual window defined in
TRNBuild/Type56 to be different.<br>
<br>
One other caution about Type34; the model computes a diffuse sky
view factor and the amount of diffuse radiation falling on the
receiver. In its computation, it assumes an isotropic sky. In order
to be most correct, you should put your Type15 (or other weather
data reader/processor) into isotropic sky mode. I have found,
however, that the change between the isotropic and anisotropic sky
models can have a greater impact on the building energy use than do
the shading features themselves. Since the anisotropic sky models
are much preferred over the isotropic model, I tend to leave Type15
set in its Perez diffuse sky mode and then pass both the shaded and
unshaded diffuse radiation to an online plotter and make sure that
the calculated values make sense.<br>

<div style="">I'm doing simulation for a window with grid
shading. The height of the window is 1.2 m and the width of
the window is 1.8 m. The grid shading divided the window into
8 parts, each part is 0.45 m width and 0.6 m height. The depth
of the shading is 0.1 m. In type 56 I could only input the
window area. In type 34 I can input the projection of the
overhang and fin, both are 0.1 m. I think the receiver means
the window area for each divided part in my case, so I input
0.45 m for the width and 0.6 m for the height. Could anybody
tell me this is correct or wrong?</div>
