Dirty fix to allign the textures: convert to morph. Perhaps you can keep the curtainwall and put a single surface morph on top of the panels that you would like to allign the texture of. (copy curtain wall, convert to morph, delete what you don't need etc)
The last curved facade (in more than one direction curved) I it faked with some morphs for the preliminary designs. It didn't get past this stage yet, but beyond that it would come down to actually modelling the frames and sashes in higher detail once the plan gets more 'fixed' (less changes likely to happen).
The curtainwall tool I personally find limited beyond basic designs as well. Once you get to the point of needing proper building documentation, it won't allways suffice.
