摘要： There is provided air-conditioning control in a low power operation so as not to exceed a target demand power amount in a predetermined measurement period while preventing deterioration of comfortableness of a living space. There include a reducible-power-amount estimation unit configured to calculate, for each group, a reducible power amount by making indoor units perform, for each group, a shut-off operation for a minimum shut-off time in the first half of a demand time limit, and a reduced-power-amount determination unit configured to distribute, when a power consumption amount predicted by a power consumption amount prediction unit exceeds a target demand power amount after the first half of the demand time limit passes, the exceeding power amount to each zone, evenly distribute, in each zone, the distributed power amount to each group, and calculate, based on the reducible power amount of each group, a shut-off time of each group when each group performs the shut-off operation to reduce the distributed power amount.

摘要： A management device includes: an acquisition unit that acquires operating history data for an equipment device in a prescribed time period; and a classification processing unit that classifies, based on the operating history data acquired by the acquisition unit, an operating pattern of the equipment device in the prescribed time period. The classification processing unit includes: an operating pattern calculation unit that calculates a first operating pattern in a first time period and a second operating pattern in a remaining second time period when the prescribed time period is divided into unit time periods; a change calculation unit that calculates a degree of change in the operating pattern using the first operating pattern and the second operating pattern when the prescribed time period is divided into unit time periods; a split point calculation unit that calculates, as a split time point, a time point where the degree of change satisfies a prescribed condition for the prescribed time period; and a split processing unit that splits the prescribed time period at the calculated split time point.

摘要： An apparatus control unit (54) executes baseline judgment control of canceling power consumption limitation for a management target apparatus (20) throughout a predetermined judgement period within a demand term. A demand control execution judgment unit (48) judges whether or not a value of a baseline BL, which is an estimated value based on an integrated value of power consumption per building in the judgment period, exceeds a demand control execution value P_Dmd by a demand-term end point. When it is judged that the value of the baseline BL exceeds the demand control execution value P_Dmd by the demand-term end point, the apparatus control unit (54) executes demand control of limiting power consumption of the management target apparatus (20), after the judgment period. Furthermore, when the demand control is being executed at the demand-term end point, the apparatus control unit (54) executes limitation relaxing control of gradually relaxing limitation on the management target apparatus (20), before the judgment period in a next demand term.

摘要： A CPU performs multiple regression analysis using a first regression model to calculate a tentative degree of contribution of each target facility to the total power consumption. The CPU calculates tentative power consumption of the target facility using the tentative degree of contribution of the target facility. The CPU calculates power consumption of a non-monitored facility by subtracting the total value of the tentative power consumption of the target facility from the total power consumption. The CPU classifies time-series data of the power consumption of the non-monitored facility into a plurality of clusters. The CPU performs multiple regression analysis using a second regression model to determine the degree of contribution of each of the target facilities. The CPU determines the power consumption of the target facility using the determined degree of contribution.

摘要： An energy conservation assistance apparatus includes an event occurrence time extraction unit, a degree of change calculation unit, and a display control unit. The event occurrence time extraction unit refers to facility operation history information included in a reference period and a designated period to extract occurrence times at which a predetermined event has occurred in each of the reference period and the period of interest. The degree of change calculation unit calculates a degree of change in an operation pattern of a facility obtained from a distribution of the occurrence times at which the predetermined event has occurred in the period of interest, relative to an operation pattern of the facility obtained from a distribution of the occurrence times at which the predetermined event has occurred in the reference period. The display control unit presents information regarding a degree of change to a user.
