Energy management apparatus

An energy management apparatus for managing the amount of energy that is consumed in a space including an air-conditioning apparatus and a refrigerating showcase,

• the energy management apparatus comprising:
• a controller that controls operations of the air-conditioning apparatus and the refrigerating showcase based on setting data;
• an operation data monitoring part that monitors operation data including the amounts of energy consumed by the air-conditioning apparatus and the refrigerating showcase;
• an environmental data monitoring part that monitors environmental data including an outdoor temperature around an outdoor unit for the air-conditioning apparatus and the refrigerating showcase;
• a data aggregation part that correlates the operation data with the environmental data and the setting data, which are collected in the same time zone as the operation data, to obtain a single data set and classifies the data set for each of specific environmental conditions of the environmental data;
• an environmental condition-specific analyzer that focuses on the amounts of energy consumed by the air-conditioning apparatus and the refrigerating showcase, which are included in the operation data in the data set, for each of the environmental conditions, to obtain optimum setting data for accomplishing energy saving, for each of the environmental conditions;
• a time zone-specific analyzer that obtains optimum setting data for accomplishing energy saving, for each of time zones, from an average value of the environmental conditions according to the time zones by using the optimum setting data for each of the environmental conditions that is obtained by the environmental condition-specific analyzer;
• and
• a people counter that counts the number of people in the space,
• wherein the environmental data monitored by the environmental data monitoring part includes the number of people counted by the people counter, and the environmental condition-specific analyzer is configured to correct the setting data based on the number of people included in the environmental data, to obtain the optimum setting data for each of the environmental conditions.
