Hereinafter, each step will be described with reference to Tables 1 to 3 described above.

S100 step is to set the target energy savings to achieve.

Step S110 is a step of determining the highest priority (A). Here, A is 0 because the initial value of a is zero.

Step S120 turns off the operation of the relay is connected to the lighting device to immediately turn off the operation according to the priority (step 1). After that, it is determined whether the amount of energy saved through the first step is greater than or equal to the target energy saving.

If the energy savings saved through step 1 are equal to or greater than the target energy savings, go to step S130 to generate a report that the target energy savings have been achieved and notify the user.

If the amount of energy saved through the first step is less than the target energy saving amount, go to step S430 to perform the next step of energy saving.

Step S140 is a step of determining whether the sum of the energy savings saved through the first step and the energy savings saved in the next step 2 are equal to or greater than the target energy savings.

If the sum of the energy savings saved in the first step and the energy savings saved in the next step, 2, is equal to or greater than the target energy saving, go to step S130 and generate a report that the target energy saving is achieved. Inform the user.

If the sum of the energy savings saved through the first step and the energy savings saved in the next step 2 is less than the target energy saving, it is determined whether the step is the last step (S150). Generate a report that it has not reached and notify the user. If it is not the last step, the energy saving amount of the next step is summed and compared with the target energy saving amount as described above.
