Abstract: An energy management system configured to manage operation states of load apparatuses installed in facility includes an instruction unit (14), a target evaluation unit (16), a presentation control unit (17) and a user device (60). According to a target power-saving ratio in a facility where load apparatuses (30) are installed, the instruction unit (14) controls operations of the load apparatuses (30). The user device (60) has a function for displaying information. The target evaluation unit (16) evaluates consumption of utility energy by the load apparatuses (30) with respect to a predetermined target value. The presentation control unit (17) controls so that the user device (60) displays an icon of which form varies according to an evaluation result by the target evaluation unit (16).

Abstract: The obtainment unit obtains information indicative of a content of manual-operation performed by a user regarding control of an intended apparatus from a group of loads, and stores it as manual-operation information including an obtaining time. The identification unit identifies a type of control of the manual-operation information. The determination unit counts the number of times of obtaining the manual-operation information within a counting period equal to two days or more, for each type and for each time period, and determines whether the number of times of obtaining the same type of manual-operation information within the same time period is equal to a predetermined threshold or more. When the number of times of obtaining the same type of manual-operation information within the same time period is determined to be equal to the predetermined threshold or more, the schedule change unit changes a control schedule based on this manual-operation information.

Abstract: An information analysis unit of a management apparatus searches for a device existing within a predetermined distance from a portable terminal, namely a device positioned near the portable terminal, based on terminal position information received from the portable terminal by a radio communication unit and device position information stored in an information storage unit. The information analysis unit reads, from the information storage unit, energy usage information of the searched device existing near the portable terminal, and transmits it from the radio communication unit to an information acquisition unit of the portable terminal. Thus, the information acquisition unit acquires only the energy usage information of the device positioned near the portable terminal, so that a display unit displays only the energy usage information of the device positioned near the portable terminal.

Abstract: Apparatus administration system includes control device that controls operation of apparatuses and display device communicable with the control device. In the control device, control unit controls each apparatus in accordance with operation schedule stored in schedule storage unit. Operation history storage unit stores operation history in which past operation states are associated with operated dates and times. In the display device, information acquisition unit acquires the operation schedule and the operation history from the control device. Date and time setting unit specifies past date and time to set as set date and time. Estimation unit estimates operation state at the set date and time through the operation schedule. Extraction unit extracts actual operation state at the set date and time from the operation history. Display unit displays the operation state under schedule control and the actual operation state adjacently.

Abstract: A collective setting part sets a collective usage permission period for lighting loads, and a separate setting part sets a separate usage permission period for the lighting loads. The relevance information memory stores relevance information that is obtained by relating each of starting times and ending times of the separate usage permission periods to a starting time or an ending time of the collective usage permission period. When the collective usage permission period is modified through a user terminal, the separate setting part modifies the starting times and the ending times of the separate usage permission periods so as to interlock with modified content for the starting time or the ending time of the collective usage permission period related in the relevance information.

Abstract: Provided are: information acquisition unit that periodically acquires usage state information of resource by load; user terminal that creates permitted usage period data; period setting unit that sets each load's permitted usage period based on permitted usage period data; determination unit that determines whether each load's resource usage is within permitted usage period; and display unit that distinctively displays whether resource usage period is within permitted usage period based on determination result by determination unit. User terminal creates single batch permitted usage period data. Period setting unit includes batch setting unit that performs batch setting whereby batch permitted usage period is set as permitted usage periods of all loads.

Abstract: Providing an energy-saving diagnostic system with which an energy saving effect brought about by modifying schedule control information can be confirmed easily. A comparison and evaluation unit 28 sets a point in time at which schedule control information is modified by a schedule setting unit 25, as a start point of an evaluation mode. When the evaluation mode starts, the comparison and evaluation unit 28 sets use information obtained over a predetermined period (i.e. in units of days, weeks, months, or years) before the start point of the evaluation mode as reference data, sets use information obtained over the predetermined period after the start point as performance data, and compares the reference data with performance data constituted. The comparison and evaluation unit 28 outputs a comparison data and to cause a user terminal 3 to display the energy saving effect brought about by modifying the schedule control information.
