A management apparatus for an air-conditioning apparatus configured to manage a plurality of air-conditioning apparatuses configured to condition air in an air-conditioning target space includes: a management-side communication unit to receive data of arrival locations and arrival times in the space transmitted from a plurality of terminal devices; and a management-side arithmetic unit configured to perform totaling based on the data of the arrival locations and the arrival times received by the management-side communication unit, and to perform a process of determining an order in which operation is started in the plurality of air-conditioning apparatuses. Operation is performed in order, and thus a steep increase in power consumption can be reduced.
