Help with texturing a poly modelled building

[Toothless Stitch 2,901]

Hello community.

As you can see, I have a question: I have a poly modelled bulding which has about 80000 polygons and about 83000 verteces. In the past I laways textured a building by using Multi/sub object. But I júsed it for lower buildings. I've never made such a huge building before so I think I need a new method to texture this kind of buildings. I have already asked some guys by pm but maybe some of the other guys can help me.

A pic of the building btw;:

You could experiment with the selection tools and possibly detach some of the pieces as elements to make it easier. For the mullions select one of the edges in the middle of it then do a dot loop so it selects only the mullions, then ring it, convert it to a polygon selection, hit grow to get the depth of the mullions then unselect any polys you don't want. That's how I would try at first as an example. How much of this is one piece?
