Abstract: Air-conditioning preferences of room users are read in order to compare a room temperature with air-conditioning preferences of the room users. Additionally, factors influencing the room temperature are detected and fed to a simulator in order to simulate the room temperature. A respective energy requirement for adapting the room temperature to the air-conditioning preferences is simulated by the simulator on the basis of the detected influencing factors for different distributions of room users in the room. An energy-saving distribution of the room users is then ascertained on the basis of the simulated energy requirement. Position allotment information for room users is also output according to the energy-saving distribution.
