Zusammenfassung:	To provide a demand management system in which a demand value of an apartment including a private section in which a heat-pump water heater is disposed can be reduced.SOLUTION: A demand management system includes heat-pump water heaters that are installed in respective private sections, and a control system that controls operation of the heat-pump water heaters. The control system previously identifies a private section the power using tendency of which is the same during multiple days. The control system predicts whether or not the demand value is equal to or greater than a threshold in each of continuous demand time sections of a prescribed time period from night to morning. When the demand value is predicted to be equal to or greater than the threshold, the control system changes an operation start time of the heat-pump water heater in the identified private section within the prescribed times period in such a way that the demand value of the prescribed time period is less than the threshold. The control system operates the heat-pump water heater in the identified private section at the changed operation start time.SELECTED DRAWING: Figure 4 【課題】ヒートポンプ給湯機を備える専用部を有する集合住宅のデマンド値を低減可能なデマンド管理システムを提供する。【解決手段】デマンド管理システムは、複数の専有部の各々に設置されたヒートポンプ給湯機と、各ヒートポンプ給湯機の動作を制御する制御システムとを備える。制御システムは、複数の日において同じ傾向で電力を使用している専有部を予め特定している。制御システム、夜間から朝にかけての連続する所定の時間帯の各デマンド時限において、デマンド値が閾値以上になるか否かを予測する。制御システムは、デマンド値が閾値以上になると予測された場合には、特定された専有部のヒートポンプ給湯機の稼働開始時刻を、所定の時間帯におけるデマンド値が閾値未満になるように、所定の時間帯内で変更する。制御システムは、変更された稼働開始時刻に、特定された専有部のヒートポンプ給湯機を動作させる。【選択図】図４
