Once you put the metal emblem found in the morgue into the hole found in one of the offices, reloading the area can save 0.5 to 1 second. Though this is a very small time save, it is very easy to pull off with decent movement.

In the gif link provided it compares the times between simply waiting and reloading the area. The left screen is simply waiting and the right being reloading the area.
