An air conditioning management device mutually communicably connected to a plurality of air conditioners, characterized by comprising: a storage that stores connection information indicating remote control devices respectively connected to and controlling the plurality of air conditioners and indicating the air conditioners respectively connected to these remote control devices, a plan view of each floor where the plurality of air conditioners are installed, air conditioner position information indicating the installation position of each of the air conditioners on the plan view, a room area information containing a coordinate group that indicates positions of areas on the plan view expressed by the plan view information where rooms exist, door/window position information indicating positions of a door and/or a window on the plan view, and area settings data that groups, for each room, air conditioner identification information indicating the air conditioners managed by the air conditioning management device, and door/window identification information indicating doors and windows on each floor; wherein the area setting data is created on the basis of the air conditioner installation position information, the room area information, and the door/window position information; a wasteful operation determiner that determines whether or not any of the plurality of air conditioners are in a wasteful operating state; and a wasteful operation notifier which, in the case where the wasteful operation determiner determines that at least one air conditioner of the plurality of air conditioners is in the wasteful operating state, notifies that the air conditioner is in the wasteful operating state to the remote control device connected to that air conditioner, on the basis of the connection information stored in the storage, wherein the wasteful operation determiner further estimate the position of a door and/or window causing wasteful operation of the air conditioner determined to be in the wasteful operating state, based on the area settings data, the room area information, and the door/window position information stored in the storage, and the wasteful operation notifier additionally notifies the position of the door and/or window estimated by the wasteful operation determiner in the notification. a storage that stores connection information indicating remote control devices respectively connected to and controlling the plurality of air conditioners and indicating the air conditioners respectively connected to these remote control devices, a plan view of each floor where the plurality of air conditioners are installed, air conditioner position information indicating the installation position of each of the air conditioners on the plan view, a room area information containing a coordinate group that indicates positions of areas on the plan view expressed by the plan view information where rooms exist, door/window position information indicating positions of a door and/or a window on the plan view, and area settings data that groups, for each room, air conditioner identification information indicating the air conditioners managed by the air conditioning management device, and door/window identification information indicating doors and windows on each floor; wherein the area setting data is created on the basis of the air conditioner installation position information, the room area information, and the door/window position information; connection information indicating remote control devices respectively connected to and controlling the plurality of air conditioners and indicating the air conditioners respectively connected to these remote control devices, a plan view of each floor where the plurality of air conditioners are installed, air conditioner position information indicating the installation position of each of the air conditioners on the plan view, a room area information containing a coordinate group that indicates positions of areas on the plan view expressed by the plan view information where rooms exist, door/window position information indicating positions of a door and/or a window on the plan view, and area settings data that groups, for each room, air conditioner identification information indicating the air conditioners managed by the air conditioning management device, and door/window identification information indicating doors and windows on each floor; wherein the area setting data is created on the basis of the air conditioner installation position information, the room area information, and the door/window position information; a wasteful operation determiner that determines whether or not any of the plurality of air conditioners are in a wasteful operating state; and a wasteful operation notifier which, in the case where the wasteful operation determiner determines that at least one air conditioner of the plurality of air conditioners is in the wasteful operating state, notifies that the air conditioner is in the wasteful operating state to the remote control device connected to that air conditioner, on the basis of the connection information stored in the storage, wherein the wasteful operation determiner further estimate the position of a door and/or window causing wasteful operation of the air conditioner determined to be in the wasteful operating state, based on the area settings data, the room area information, and the door/window position information stored in the storage, and the wasteful operation notifier additionally notifies the position of the door and/or window estimated by the wasteful operation determiner in the notification.
