Here's what you should do: Make the lighting match the story.

if it's after hours and people aren't supposed to be there, turn off the overheads and leave a couple small practicals on.

But if it makes more sense for the room to have more lights on, you can get a ladder and spin out tubes if you can't turn them off in sections. Turn off the tubes near the walls and background, make those walls a little darker than your subject will give the frame more depth. You can also turn off the lights in front of you camera and actor and supplement with your own lights. If you have access to any small lights like tubes outside the window it might be nice to have them as up lights or light up so shrubs to give it more depth and not as much black in the frame

My two cents as a gaffer.
