Besides a scene change at night, the entire building is automated through the projection system. All of the lighting in the lobby, outside signage, main hallway, restrooms, etc and HVAC is programmed to work in conjunction with the movie schedule based off of various parameters such as "X number of minutes before the first show of the day do A, B and C". This achieves maximum energy efficiency since all of the systems in the building are working from the movie schedule rather than a hard-programmed on/off timer.
