An air conditioning operation analysis device includes: an air conditioning operation data acquirer that acquires air conditioning operation data of at least one air conditioner installed in a room, a room information acquirer that acquires room information indicating a configuration of the room, an environmental information data acquirer that acquires environmental information data from at least one sensor arranged in the room, and an outputter that outputs heat load data that is calculated based on the acquired air conditioning operation data, the acquired room information, and the acquired environmental information data.

A first comparison-period specifier specifies a first to-be-compared period in a pre-implementation period before implementation of an energy saving control. A second comparison-period specifier specifies as a second to-be-compared period a to-be-compared candidate period having the highest similarity level between: parameters in a first parameter comparison period including a first comparison period and a first period immediately before or after the first comparison period, and parameters in a second parameter comparison period including a to-be-compared candidate period and a second period immediately before or after the to-be-compared candidate period. An energy saving diagnoser diagnoses the level of energy saving derived from the implementation of an energy saving control based on a power consumption amount in the first to-be-compared period and a power consumption amount in the second to-be-compared period.

A remote controller includes a user interface, a rotational state detector, and a controller. The rotational state detector detects a rotational state of the remote controller. The controller, based on the rotational state detected by the rotational state detector, selects a display mode from among a plurality of display modes depending on different user tiers. Then the controller causes the user interface to display an operation screen in the selected display mode.

A monitoring system includes electric devices, communication adaptors communicably connecting the electric devices with a network, and a monitoring device monitoring the status of each electric device. The monitoring device acquires from user input a type of running indicating whether or not the status of the electric device is always ON. The monitoring device transmits to each electric device a status acquisition request requesting acquisition of the status of the electric device. Then the monitoring device determines the status of the electric device based on a response to the transmitted status acquisition request and the acquired type of running.

A facility equipment operation device includes an affected section determiner and a mismatch detector. An affected section determiner computes an affected section that is affected by a controlled equipment that is facility equipment with a changed control parameter, by referencing data including an installation position of facility equipment in an objective space, and a capability related to an area affected by the facility equipment. The mismatch detector detects a mismatched state on the basis of whether or not an effect exerted by the controlled equipment on the affected section when the controlled equipment operates according to the changed control parameter, and an effect exerted on the affected section by a facility equipment currently operating, are in a predetermined relationship.
