(Maxwell) Tips on rendering large scale site plan with light

[tranman100]

Hi,
I'm working on a large scale site plan with many buildings. I'd like to create a rendering of these buildings with lights inside of them to show the mood at night. Here's an example of what i'm trying to achieve (mine is a larger scale though):

Do any of you have any tips of how to model buildings in such a way to easily create this sort of light effect?
I was thinking of using windowizer (plugin to create windows in sketchup) and assign the glass as an emitter but I was wondering if there's a more efficient and easier way.
I'm using Maxwell Render by the way.

Thanks!
