Not to sidetrack this thread, but generally it is hard to build an office building without windows, at least on private land in an urban area. The
project would meet severe resistance in the planning department. There are so many energy/environmental laws these days. Now server farms, telephone
central offices, etc. can be built without windows. [These are the most common buildings without windows that you find in urban areas.] But if the
building is to be occupied by people, it would probably be required to have windows.
What the spooks do for privacy is vibrate the windows with white noise to make monitoring impossible. For classified conversations, the building will
have a SCIF in the interior.
If you look at CIA HQ, there are plenty of windows.
Some seriously geeky website has a photo gallery of telephone central offices. Most have one window at most.
There is that fine line between an office building and an industrial building. Industrial buildings don't require windows. I've seen some buildings
on the border between office and industrial, mostly laboratories. Often if you have the address of the building or know how to find the building on a
plat map, you can find the owner and determine the use. One very strange building I found in Berkeley turned out to be a medical laboratory. It had a
few windows, but they had cinder block in front of them a few feet away from the glass. Possibly it had a shadier past.
