Eva, 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. 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. 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).
