<p>A system for determining a human occupation of a number of rooms (2a, 2b, 2c) comprises a number of presence measuring devices (4a, 4b, 4c) for the rooms. The presence measuring devices provide a presence indication 'free' if no persons are present and 'occupied' if persons are present in the rooms. A data processing device (10) is configured for reading-out the presence measuring devices, wherein for each room in a memory device at least combinations are registered of an identification indication concerning an identification of the room, the presence indication pertaining to the room, and a time stamp indication concerning the current date and time of registration of the presence indication. The data processing device is further configured for receiving an input from an input device and, in response thereto, representing, on the basis of the combinations of indications stored in the memory device, an overview of the rooms and their human occupation over time.</p> |
