Either method will work. I would lean towards drawing the building
in Trnsys3D and drawing the balconies as shading surfaces. Once you
get to TRNBuild, make sure to tell it to generate the shading mask.
Once you do, the building form and the location of the balconies
will be taken into account as far as shading the windows goes.<br>
<br>
For Type34, you would need one instance of Type34 for each shaded
surface that you want to consider. The surface can be either a wall
or a window but you must define a new orientation in TRNBuild for
each surface that is going to receive a different amount of solar
radiation.<br>
<br>
I think Type67 is not appropriate in this case; it was designed to
deal with objects that shade the building from nearby (like another
building across the street) and is not set up to deal with objects
that shade a surface from above (like a balcony does).<br>
<br>
Kind regards,<br>

<div>I model a two storey building with balconies in all
elevations so the first floor is shaded by the balconies of the
above floor. How can I model the balconies? If I model them in
type 56 does the shading from taken into account? Do I have to
use type 34 (shading from overhangs)? If yes do I have to use as
many components of type 34 as the number of the openings (each
component describe only one opening with overhangs)? Can I
approach this case with type 67 (shading mask)?</div>
<div>Thank you.</div>
