Abstract: An energy management system includes an energy management apparatus configured to mange energy supplied to equipment devices of a plurality of buildings, and a control apparatus configured to control the equipment devices in the buildings. The energy management apparatus is located superordinate to the buildings. The control apparatus is connected to the energy management apparatus. The control apparatus includes an operating status perceiving unit configured to perceive operating status of the equipment devices, and a reducing capability presentation unit configured to present a plurality of energy reducing capabilities for at least one condition to the energy management apparatus. The energy reducing capabilities are amounts of energy that can be reduced for the equipment devices based on the operating status perceived.

Abstract: The purpose of the present invention is to provide an energy management system that works both to reduce energy and to maintain amenity in each building. The energy management system (100) of the present invention is provided with an energy management apparatus (10) and a control apparatus (30, 30). The energy management apparatus is located superordinate to a plurality of buildings, and manages energy supplied to equipment devices provided to each building. The control apparatus is connected to the energy management apparatus, and controls the equipment devices in the buildings. The control apparatus has an operating status perceiving unit (36a, 236a, 336a, 436a) and a reducing capability presentation unit (36g, 236g, 336g, 436g), The operating status perceiving unit perceives the operating status of the equipment devices.

Abstract: A first management apparatus that is connected to a first equipment device group including a plurality of first equipment devices centrally manages the first equipment devices. A second management apparatus connected to a second equipment device group including a plurality of second equipment devices separate from the plurality of first equipment devices centrally manages the second equipment devices. A group management apparatus connected to the first and second management apparatus centrally manages the first and second equipment device groups. The first and second management apparatus include first and second management programs to centrally manage the first and second equipment devices. The group management apparatus includes a group management program for centrally managing the first and second equipment device groups.

Abstract: An air conditioner managing apparatus includes a storage unit configured to accumulate operation data about numerous indoor units, a first screen generating unit, a second screen generating unit and a display switching unit. The first screen generating unit is configured to generate a first screen on which a plurality of the numerous indoor units with a problem can be visually verified based on the operation data. The second screen generating unit is configured to generate a second screen on which the operation data related to a specific one of the plurality of indoor units can be visually verified. The display switching unit is configured to switch to the second screen relating to the specific one of the plurality of indoor units when the specific one of the plurality of indoor units displayed on the first screen is selected and an input of a prescribed button is accepted.
