This isn't your home with open stairwells and loose venting doorjams. This is a thirteen story office building with elevators and badged access easements.

I assure you, heat passes through elevator shafts and floors just fine, and office buildings aren't usually built like a BSL-4 laboratory. If anything, they're typically less insulated than a regular old house.
