Apparatus and method for evaluating an energy saving behavior

An apparatus for evaluating an energy saving behavior, comprising:

• an appliance measurement interface configured to input an appliance measured value from each appliance, the appliance measured value including an electric energy consumption, a usage intensity and a usage frequency of the appliance;
• an appliance measured value database configured to store the appliance measured value;
• an appliance information count unit configured to calculate an average of the appliance measured value in an evaluation span;
• an appliance information database configured to store an appliance information as the average of the appliance measured value;
• an evaluation unit configured to acquire a first appliance information in a first evaluation span and a second appliance information in a second evaluation span from the appliance information database, and calculate an evaluation value by applying the first appliance information and the second appliance information to an evaluation function, the first evaluation span being an evaluation object period, the second evaluation span being a comparison object period;
• an evaluation result database configured to store the evaluation value;
• and
• a display unit configured to display an evaluation result of the energy saving behavior based on the evaluation value.
