A tour of my tower

Question

A new riddle - I don't think it should give anyone too much trouble!

Let me show you my building - do you like the lovely green carpet?
All the rooms are connected by these hallways.

Downstairs are the archives - we keep all our records there.
It takes a while to find anything, but it's a safe place for them.

Across the hall are the libraries, much easier to navigate but a bit small.
The librarian is often heading downstairs to swap out books.

The generator is near too, we use a lot of power!
If that goes, then we're all lost.

The artists studio is next door, he loves to paint and draw.
Sometimes he gets a bit hot though, so he'll open the windows for a breeze.

Down from him is the recording studio,
It gets a bit noisy in there.

The radio room is at the end of the corridor.
Operators are constantly in communication.

This is my office, in the middle of it all.
Everyone brings me work to do.

In days past I would be alone in this room, but now I have a few helpers with me.
Sometimes it still feels like we are doing two things at once though.

Who am I, and where do I work?

Thoughts

I've taken apart a few PC's but never built one from scratch. That would have helped for a more complete answer. Thanks for your patience and assistance.
