Drew,
The thought behind the settings for time lapse are the same as regular. Only you have to think of how the scene will change and where the light will be coming from throughout the duration.
1. Start with the thought of everything automatic.
2. Then think of what are trying to show, if it is the building itself, I would go to manual focus, and focus on the building. That way autofocus won't change due to things moving in the picture.
Then start thinking about overiding the automatic settings.
3. If things are going to be moving in your picture, like cars moving, decide if you want them to show up, or don't. If you do, then you want to shoot at a higher shutter speed, like around 1/200th of a second. If you want them to not show up, then go slow like 1/60th.
4. The leaves your aperature as the only thing left. Let that stay on automatic.
5. Alternatively, if you want to make sure everything is always in focus, set your iris to something smaller, like 5, or 6. Then let the shutter speed change automatically.
