The target of reducing the amount of electric power is reduced, and the target environmental characteristic value (environmental control target value) is calculated for each of the areas A to L (step S403), and the environmental characteristics of the areas A to L achieve this target. As described above, an operation plan for controlling the environmental adjustment device 108 is created (step S404).

  As a subsequent process, the CPU 160a of the server 106 issues a control command for controlling the environment adjustment device controller 108a so that the environment adjustment device 108 is driven so that the operation plan created in step S404 is achieved. It transmits toward 108a (step S405). The environment adjustment device controller 108a transmits a control signal corresponding to the control command received by the communication unit 164 to the control circuit 108b, and each environment adjustment device drive unit 108c (the cooler 116, the showcase 117, the illumination 118, The air conditioner 119) is driven and controlled as planned.

  As processing subsequent to step S405, the CPU 160a of the server 106 monitors the environmental characteristic distribution information stored in the RAM 160c (step S406), and determines whether or not the environmental characteristic of the sales floor space 104 has changed according to the operation plan. (Step S407). When it is determined that the environmental characteristics have not changed according to the operation plan (N in step S407), the CPU 160a of the server 106 drives and controls the environment adjustment device drive unit 108c so as to correct the operation state of the environment adjustment device 108. Is sent to the environmental control device controller 108a (step S408), and the process returns to step S406.

  On the other hand, if it is determined in step S407 that the environmental characteristics are changing as planned (Y in step S407), the CPU 160a of the server 106 sends the environmental adjustment device 108 from the watt-hour meter 165 to the environmental adjustment device controller. By transmitting a request signal for requesting the server 106 to transmit the power consumption input to the server 108a, and receiving the power consumption transmitted from the environment adjustment device controller 108a constituting the environment adjustment device 108. The power consumption is acquired (step S409). As a subsequent process, the CPU 160a of the server 106 obtains a difference between the power consumption acquired in step S409 and the power consumption when the environment adjustment apparatus 108 is driven without following the control command, and based on this power consumption. The amount of CO2 emission reduction is calculated (step S410). The power consumption when the environmental adjustment device 108 is driven without following the control command is stored in advance in, for example, a nonvolatile storage unit (not shown) provided in the environmental adjustment device controller 108a. As an example, the amount of power consumed when the environmental adjustment device 108 is driven without following the control command is the same as the environmental adjustment device 108 (not shown) of the environmental adjustment device controller 108a regardless of the control command from the server 106. While the drive unit 108c is being controlled, the controller circuit writes the power consumption input from the watt hour meter 165 into the nonvolatile storage unit. Various methods for calculating the CO2 emission reduction amount can be employed. As an example, the calculation method presented in the “Guidelines for calculating greenhouse gas emissions from businesses” presented by the Global Warming Countermeasures Division of the Global Environment Bureau of the Ministry of the Environment, A calculation method obtained by multiplying by the carbon dioxide emission coefficient can be used. As processing subsequent to step S410, the CPU 160a of the server 106 transmits the calculated CO2 emission reduction amount to the headquarter server 133 and each information display device 107 (step S411). After finishing the process of step S411, CPU160a of the server 106 returns a process to step S401.

  When the CPU 155a of the information display device 107 determines that the CO2 emission reduction amount transmitted from the server 106 has been received, the CPU 155a executes a process of displaying the received CO2 emission reduction amount on the electronic paper 151 as the environmental action information 157. If the information processing unit (not shown) of the headquarter server 133 determines that the CO2 emission reduction amount transmitted from the server 106 has been received, the received CO2 is stored in the database that stores the CO2 emission reduction amount for each store. The information on the emission reduction amount is stored in association with the store code for each store.

  In the supermarket 102 in which the information display system 101 configured as described above is introduced, a plurality of information display devices 107 are distributed and arranged in the sales space 104. The environmental characteristic measurement tag 158 attached to the information display device 107 measures the environmental characteristics (temperature, humidity, illuminance, etc.) around the information display device 107, and generates environmental characteristic information based on the measurement results. The environmental characteristic information is periodically or together with a specific code for identifying the information display apparatus 107 when the microcomputer 155 of the information display apparatus 107 determines that the environmental characteristic information transmission request command from the server 106 has been received. Sent to the server 106. In the server 106, the collected environmental characteristic information is stored in the measurement data recording file F1. Then, the server 106 refers to the measurement data recording file F1 in which environmental characteristic information is accumulated and stored, and the tag arrangement position file F2 in which the arrangement position where the environmental characteristic measurement tag 158 is arranged is referred to. Environmental characteristic distribution information indicating a distribution state of environmental characteristics (temperature, humidity, illuminance) in the space 104 is generated and stored in the RAM 160c. This environmental characteristic distribution information is displayed on the information display device 107 attached to the merchandise display shelf 112 together with the merchandise information 156 so that it can be noticed by customers who are shopping.
