Most of the shots in this short were correctly exposed(except in the beginning and ending scenes where some noise is clearly visible) so the only changes were white balance and to give the short film an all around colder look.
There were 2 universes: night and day, and the grading had to vary depending of the scene.
Final look a lot more cold, the "red room" was created using blending modes and a mate.
