Information terminal control method and energy conservation support system

An information terminal control method performed by a processor of an information terminal executing instructions stored in a memory, the method comprising:

• predicting an amount of power consumption in an area in each period of a plurality of periods;
• determining whether the predicted amount of power consumption in each period of the plurality of periods exceeds a target value of the power consumption in each period of the plurality of periods;
• when there is a first period, of the plurality of periods, in which the predicted amount of power consumption is determined to exceed the target value, causing a display of the information terminal to display a first screen including a time-sequence diagram of the plurality of periods, in which the first period is displayed distinctively from a second period of the plurality of periods, where the predicted amount of power consumption in the second period is determined not to exceed the target value;
• and
• causing the display to display a second screen including a message that presents an action to be performed in the second period to reduce the amount of power consumption in the first period to be less than the target value,
• wherein a content of the message displayed on the display is changed according to a grace period before the first period starts, and
• wherein the action in the message that is displayed when the grace period is a first grace period leads to a larger amount of reduction in the amount of power consumption than the action in the message that is displayed when the grace period is a second grace period that is longer than the first grace period.

An energy conservation support system comprising:

• a memory that stores instructions;
• and
• a processor that, when executing the instructions stored in the memory, performs operations including:
• predicting an amount of power consumption in an area in each period of a plurality of periods;
• determining whether the predicted amount of power consumption in each period of the plurality of periods exceeds a target value of the power consumption in each period of the plurality of periods;
• when there is a first period, of the plurality of periods, in which the predicted amount of power consumption is determined to exceed the target value, causing a display of an information terminal to display a first screen including a time-sequence diagram of the plurality of periods in which the first period is displayed distinctively from a second period of the plurality of periods, where the predicted amount of power consumption in the second period is determined not to exceed the target value;

• causing the display to display a second screen including a message that presents an action to be performed in the second period to reduce the amount of power consumption in the first period to be less than the target value,
• wherein a content of the message displayed on the display is changed according to a grace period before the first period starts, and
• wherein the action in the message that is displayed when the grace period is a first grace period requires longer time to reach a maximum reduction in the amount of power consumption than the action in the message that is displayed when the grace period is a second grace period that is shorter than the first grace period.
