Various utility portals that enable utility companies to manage demand-response events are disclosed. The disclosed utility portals include several different options for enabling utility companies to communicate information to and received information from an energy management system. The energy management system can host the portal and can carry out a demand response event via intelligent, network-connected devices based on information provided by the utility company.
摘要:
Asmart-home device comprises a user interface including an electronic display having a first display mode and a second display mode, the first display mode generally requiring more power than said second display mode. The device further comprises a processing system coupled to the user interface. The processing system is configured to be in operative communication with one or more environmental sensors for determining at least one environmental condition, and in operative communication with one or more input devices including said user interface. The device further comprises at least one sensor configured to detect a physical closeness of a user to the at least one sensor. The at least one sensor is in operative communication with the processing system. The processing system is configured to cause the electronic display to be in the first display mode when a closeness threshold has been exceeded. The processing system is further configured to automatically adjust said closeness threshold based at least in part on a historical plurality of physical closeness events as detected by the at least one sensor.

Provided is an air conditioning control system in which after an adjustment of a consumed energy amount has been performed, the timing of performing the next adjustment of the consumed energy amount can be appropriately established. An air conditioning control system for adjusting the consumed energy amount of air conditioners installed in a property within an adjustment time period comprises a control apparatus and an assessment apparatus (130). The control apparatus performs adjustment control for controlling the air conditioners so that the consumed energy amount is adjusted in the adjustment time period. After the adjustment time period, the assessment apparatus (130) assesses the possible amount of the next adjustment control on the basis of environmental parameters of the air conditioned spaces.

The air-conditioning control apparatus according to the present invention can conserve energy as well as maintain a comfort level. The air-conditioning control apparatus (40) includes an away detector (41), a position acquisition unit (42), a distance acquisition unit (43), and an instrument control unit (44). The away detector (41) detects that a user (92) is away from a building (90). The position acquisition unit (42) acquires position information of a portable terminal (20) carried by the user (92). Using the position information acquired by the position acquisition unit (42), the distance acquisition unit (43) acquires distance information indicating how far the portable terminal (20) is from the building (90) when the away detector (41) has detected that the user (92) is away. The instrument control unit (44) controls an air conditioner (50) installed in the building (90) on the basis of the distance information acquired by the distance acquisition unit (43) so that the air conditioner (50) consumes less energy.

The conditioning unit (10) comprises: - means (17, 18, 19) for detecting temperature and humidity for the primary flow (12) and the secondary flow (13) at the inlet of the conditioning unit (10) and for the primary flow (12) at the delivery toward an environment to be air-conditioned (14), - means (20, 21) for detecting the flow-rate of the primary flow (12) and of the secondary flow (13), - means (22, 23) for detecting the electric power absorbed by the first fans (15) and the second fans (16), - an electronic control and management unit (24) adapted to collect and process the data detected by the detection means (17, 18, 19, 20, 21, 22, 23) and, on the basis of the detected data, adapted to adjust the speed of the first fans (15) and the second fans (16).
摘要:
An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.
