What Is This Fly?

I work in a medical office on the second floor and we have large windows. There are a few houseplants at the window. I noticed these small flies every day. They keep coming from somewhere, but our windows don’t open so they may live inside the building. They are very sluggish, I can pick them up with my fingers or hands. They don’t fly away like normal flies. I find many of them sitting by the window, usually dead and drying up. I can’t seem to figure out what they are, and where they are coming from. Can you please help?
This is an amazingly detailed image of a Bathroom Fly. Bathroom Flies breed in the sludge that accumulates in drain pipes. They are also called Drain Flies or Moth Flies.
