Abstract

An energy reducing apparatus includes: an input module through which to input a target energy consumption value; an acquiring module configured to acquire energy consumptions of plural apparatus every measurement period; a totaling module configured to calculate sums of energy consumptions of each of the apparatus in a prescribed period based on energy consumptions measured every measurement period; a calculating module configured to calculate a first index indicating a deviation between an average value of past energy consumptions and a current energy consumption based on energy consumptions measured every measurement period and the sums for each of the apparatus; and an allocating module configured to allocate an energy consumption to each of the apparatus so that the energy consumption value is satisfied by preferentially reducing the energy consumption of an apparatus whose first index is small.

Claims

1. An energy reducing apparatus comprising:

an input module through which to input a target energy consumption value;

an acquiring module configured to acquire energy consumptions of plural apparatus every measurement period;

a totaling module configured to calculate sums of energy consumptions of each of the apparatus in a prescribed period based on energy consumptions measured every measurement period;

a calculating module configured to calculate a first index indicating a deviation between an average value of past energy consumptions and a current energy consumption based on energy consumptions measured every measurement period and the sums for each of the apparatus; and

an allocating module configured to allocate an energy consumption to each of the apparatus so that the energy consumption value is satisfied by preferentially reducing the energy consumption of an apparatus whose first index is small.

2. The energy reducing apparatus according to claim 1, further comprising

a determining module configured to determine reductions of an use time and an average power consumption so that an energy consumption allocated by the allocating module is satisfied with a higher priority given to one of the use time and the average power consumption, which has a smaller second index, wherein:

the acquiring module acquires the use time and the average power consumption;

the totaling module calculates sums of use times and average power consumptions based on use times and average power consumptions acquired by the acquiring module for each of the apparatus; and

the calculating module calculates a second index indicating deviations between average values of past use times and power consumptions and a current use time and average power consumption based on the use times and the average power consumptions calculated by the totaling module for each of the apparatus.

3. The energy reducing apparatus according to claim 2, further comprising:

a computing module; and

a control module configured to control the individual apparatus, wherein;

the acquiring module acquires a room temperature setting value and a brightness setting value of the respective apparatus, and an air temperature and an illuminance of a state that the respective apparatus are in operation;

the computing module calculates average air temperatures and average illuminances corresponding to respective use times and average setting values corresponding to respective average power consumptions of a state that the respective apparatus are in operation based on air temperatures, illuminances, average power consumptions, and room temperature setting values and brightness setting values of the respective apparatus acquired by the acquiring module;

the determining module determines values to be used for performing a control so that the use time and the average power consumption of the apparatus determined by the determining module are satisfied based on the average air temperatures and the average illuminances corresponding to the respective use times and the average setting values corresponding to the respective average power consumptions of a state that the respective apparatus are in operation calculated by the computing module; and

the control module controls the apparatus based on the values determined by the determining module.
