An additional component that can be integrated with Building Energy Management Systems (BEMS) is a room booking system, which allows users to reserve and schedule rooms within a building. When integrated with a BEMS, room booking systems can enable efficient use of space, by automatically turning off heating and cooling when a room is unoccupied, and adjusting lighting levels based on the schedule of the room. For example, if a room is scheduled for a meeting at 3pm, the lights will be turned on and the temperature adjusted to a comfortable level before the meeting starts, and will be turned off and temperature adjusted when the meeting ends.
