1. A method for managing a building using a digital building model, the method comprising:
based on a trigger, automatically capturing an image of a room reflecting a current seating configuration in the room using a recording device comprising at least one device selected from the group consisting of: a camera, a Light Detection and Ranging (LIDAR) device, and a Laser Detection and Ranging (LADAR) device;
transferring the recorded current seating configuration to a server storing the digital building model;
analyzing the recorded current seating configuration using one or more processors associated with the server;
wherein the trigger includes either a defined point in time or a predefined event;
wherein analyzing the recorded current seating configuration includes assessing an image of the current seating configuration with a pattern recognition program by mapping the seating configuration of the room into the digital building model by a semantic segmentation based on a boundary segmentation edge detections and a semantic instance segmentation to determine whether the current seating configuration violates any rules stored in the digital building model; and
if the current seating configuration violates one or more rules, sending a warning message to a building control station and/or a display associated with the room;
if the current seating configuration does not violate any rules, storing a semantic model of the room including the current seating configuration in the digital building model.
