When the working time has passed (step 71; Y), a Ping command is transmitted to the OA device installed in the room (step 72), and it is confirmed whether there is a response corresponding to this command from each OA device. (Step 73).

As a result, when there is a response (step 73; Y), it is confirmed whether or not this OA device is in the energy saving mode state (step 74). Here, when it is not in the energy saving mode (step 74; Y), since the OA device is being used, it is determined that there are still people in the room or the like, and the process is terminated. On the other hand, in the case of the energy saving mode or when there is no response from all the OA devices (Step 74; N), the operation state of the air conditioner is confirmed by the temperature sensor provided in the room (Step 75).
If it is in an operating state (step 75; Y), a warning signal for stopping air conditioning is transmitted to the air conditioning management device 106 (step 76). Next, a signal for stopping the operating air conditioner or a signal for setting a preset temperature (control temperature at which power can be reduced) is transmitted to the air conditioning management device 106 (step 77).

As a result, if a turn-off signal is transmitted (step 92; Y), a Ping command is transmitted to the OA device in the room (step 93), and it is confirmed whether there is a response corresponding to this command from each OA device ( Step 94). Here, when there is a reply (step 94; Y), it is confirmed whether or not this OA device is in the energy saving mode state (step 95). If not in the energy saving mode (step 95; Y), a warning signal for turning off the power is transmitted to the OA equipment not in the energy saving mode (step 96).

The OA device that outputs the energy saving mode signal is an image forming apparatus or the like of a multifunction machine having a FAX function or the like.

Next, in order to confirm the operation state of the air conditioning, it is confirmed whether an air conditioning stop signal has been output from the air conditioning management device 106 of the room that has been turned off (step 98). If the air conditioning stop signal is not output (step 98; Y), a warning signal for stopping the air conditioning is transmitted to the air conditioning management device 106 (step 99). Next, a signal for stopping the operating air conditioner or a signal for setting a preset temperature (control temperature at which power can be reduced) is transmitted to the air conditioning management device 106 (step 100), and the process is terminated.
Further, when there is no turn-off signal from the lighting management device 107 in the room (step 92; N), when there is no response from each OA device (step 101; Y), or when the luminance sensor in the room is at the turn-off level (step) 102; Y), the process proceeds to step 93 and the process is continued.

When the level is reached (step 104; Y), the process proceeds to step 99, where a warning signal is transmitted. Even in the energy saving mode, the above-described processing for confirming the operation state of the air conditioning is performed.
In addition to confirming the turn-off signal from the lighting management device 107 in the room, the light-off confirmation of the room can be confirmed from a light detection sensor provided in the OA device in the room or a luminance sensor provided in the room to detect the lighting state of the light. It is also possible to carry out with the turn-off signal.
The same applies to the stop of the air conditioning operation, and the determination may be made by a signal from a temperature sensor provided in the office OA device or a temperature sensor provided in the living room to detect the operating state of the air conditioning.

Next, with reference to the flowchart of FIG. 15, a processing procedure for confirming the operation state of the air conditioner such as a living room and shifting the OA device and the lighting device to the power consumption reduction mode will be described.

The OA device that outputs the energy saving mode signal is an image forming apparatus or the like of a multifunction machine having a FAX function or the like.
And it is confirmed whether the light extinction signal was output from the lighting management apparatus 107 of the room where the air conditioning was stopped (step 118). If the turn-off signal is not output (step 118; Y), a warning signal for turning off the light is transmitted to the light management device 107 (step 119). Next, a signal for turning off the illumination is transmitted to the illumination management device 107 (step 120), and the process is terminated.
Further, when there is no operation stop signal from the air conditioning management device 106 in the room (step 112; N), when there is an air conditioning stop signal from the OA device in the room (step 121; Y), and the temperature sensor in the room is at the air conditioning stop level. (Step 122; Y), the process proceeds to step 113 and the process is continued.

Even when there is no response from each OA device in the state where the air conditioning of the room is stopped, or in the energy saving mode, the process of checking the lighting state of the illumination is performed. In addition to the operation signal from the air conditioning management device 106 in the room, the operating state of the air conditioning in the room is the temperature sensor provided in the OA equipment in the room or the temperature provided in the room to detect the temperature of the room. A temperature signal from a sensor may be used.

  If there is a response (step 133; Y), it is confirmed whether or not this OA device is in the energy saving mode state (step 134). If it is not in the energy saving mode (step 134; Y), a warning signal for turning off the power is transmitted to the OA equipment not in the energy saving mode (step 135). Next, a signal for turning off the energy saving mode or the main power source is transmitted to the OA equipment that is not in the energy saving mode (step 136). The OA device that outputs the energy saving mode signal is an image forming apparatus or the like of a multifunction machine having a FAX function or the like.

Next, in order to confirm the operation state of the air conditioning, it is confirmed whether or not an air conditioning stop signal has been output from the air conditioning management device 106 of the room that has been turned off (step 137). If the air conditioning stop signal is not output (step 137; Y), a warning signal for stopping the air conditioning is transmitted to the air conditioning management device 106 (step 138). Next, a signal for stopping the operating air conditioner or a signal for setting a preset temperature (control temperature at which power can be reduced) is transmitted to the air conditioner management apparatus 106 (step 139), and the process ends.
Moreover, the process which confirms the driving | running state of an air conditioning is implemented also in the case where there is no response from each OA apparatus in the state where the illumination of the room is turned off, or in the case of the energy saving mode.
If the lighting in the room is not at the extinguishing level (step 131; N), it is confirmed whether the air conditioning is in an operating state (step 140). As a result, when it is in the driving state (step 140; Y), it is determined that there is a holiday or holiday attendee, and the process ends.
On the other hand, if the air conditioning is in a stopped state (step 140; N), a Ping command is transmitted to the OA device in the room (step 141), and it is confirmed whether there is a response corresponding to this command from each OA device ( Step 142).

As a result, if there is a response (step 142; Y), it is confirmed whether this OA device is in the energy saving mode state (step 143). If it is not in the energy saving mode (step 143; Y), the process is terminated.
When the lighting of the living room is turned on (step 131; N), the air conditioning is stopped (step 140; N), and there is no response from the OA device (step 142; N), or in the energy saving mode ( Step 143; N), a warning signal for turning off the lighting is transmitted to the lighting management device 107 (Step 144).
