I can thing of several ways depending on the level of detail required etc...
A simple way to do the continuous glazing is to model the sloping walls and roofs, cut through them with a single wall and use SEOs to subtract and intersect. This would require some operators on hidden layers.
For a little more detail and less fuss with the SEOs you could use complex profiles to make the glazing (and the SEOs).
Another way would be to fill the cut outs wit curtain walls.
