Methods, systems, and devices for an interactive environmental control system are described. In some examples, operating temperatures for individual zones of an environment may be determined based on inputs received from occupants of the respective zones. For example, a building may be separated into zones, and environmental conditions at each zone may be monitored and adjusted independently. Each occupant of a zone may update their environmental preference and the system may utilize the user inputs to set and adjust an operating temperature for the respective zone based on the occupants' preferences. In some examples, the system may implement machine learning techniques to predict and set operating conditions for the zones based on inputs, such as a history of inputs, from building occupants (e.g., from occupants of a respective zone).

Systems and methods are provided herein for determining motion in a volume using a lighting based sensor. A status of a light is determined with which a motion sensor is associated. Motion measurements are received from the motion sensor. Based on the motion measurements, a motion score is determined. A room status is adjusted based on the motion score.

Techniques for performing an emissions demand response event are described. In an example, a cloud-based HVAC control server system receives an emissions rate forecast for a predefined future time period. Using the emissions rate forecast, a plurality of emissions differential values are created for a plurality of points in time during the predefined future time period. The emissions differential values represent a change in predicted emissions over time. Based on the plurality of emissions differential values and a predefined maximum number of emissions demand response events, an emissions demand response event is generated during the predefined future time period. The cloud-based HVAC control server system then causes a thermostat to control an HVAC system in accordance with the generated emissions demand response event.

Air-cleaning control is performed in accordance with a situation of motion of a person and brightness in a room. An air-cleaning device (100) includes: a first determination unit (11) that determines, from a detection signal from a person detection sensor (31), whether a state of an air-cleaning target room is at least any of a state where a person is absent in the air-cleaning target room, a state where a person is present and a motion amount is small, and a state where a person is present and the motion amount is large; a second determination unit (12) that determines, from a detection signal from as illuminance sensor (32), whether the state of the air-cleaning target room is at least any of a state where it is bright inside the air-cleaning target room and a state where it is dark inside the air-cleaning target room; and an operation control unit (13) that controls an operation of an air-cleaning function by using determination results of the first determination unit (11) and the second determination unit (12).

A camera takes an image of a user. A room environment information sensor detects room environment information about an environment in a room where the user is present. An estimation unit estimates a concentration degree of the user based on the image of the user taken by the camera and the room environment information sensed by the room environment information sensor.

A hybrid clean room system includes: a clean room which includes a plurality of side walls arranged in the vertical direction between a floor part and a ceiling part; a circulation part which is disposed outside of the clean room, and which forms a closed space along the upper plate with the other two facing side walls from among the plurality of side walls; an air pump disposed in the circulation part; a plurality of discharge ports, which are arranged on the other two facing side walls from among the plurality of side walls so as to supply, to the clean room, the air that is discharged from the air pump and passes through the circulation part; a suction part disposed at at least one of the plurality of side walls, and connected to the air pump.

A spatial temperature estimation system includes a thermal image acquisition unit and a space temperature estimation unit. The thermal image acquisition unit is configured to detect a temperature of at least one surface of a ceiling, a floor, or a plurality of walls of a room. The space temperature estimation unit is configured to estimate a temperature of air in an interior space of a room with reference to a CRI coefficient relating to the at least one surface and the temperature detected by the thermal image acquisition unit.

The air conditioning system comprises: an air conditioner; an inference device to infer data representing a total amount of a power demand value exceeding a set value for a prediction target period from input data including at least one of operation data of the air conditioner for a period prior to the prediction target period, state data of a user of the air conditioner for the period prior to the prediction target period, weather prediction data for the prediction target period, or characteristic data of the room in which the air conditioner is installed; and a control device to cause the air conditioner to perform a heat storage operation depending on a predicted value of the total amount of the power demand value.

Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a “wellness” or sense of “wellbeing” provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for “jet lag” or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and/or facility personnel, as is instruction, and surveys, including assessing wellness.

An air conditioner and a method for operating an air conditioner are provided. The air conditioner may include a case having a space formed therein and an open bottom; a panel disposed under the case and having an inlet and a plurality of outlets disposed around a circumference of the inlet; a fan disposed in the case and configured to generate an airflow from the inlet to the plurality of outlets; an airflow direction controller disposed at the plurality of outlets and configured to control an airflow direction of air flowing through the plurality of outlets in a plurality of directions; a camera disposed at one side of the panel and directed toward an indoor space; and a controller configured to control the airflow direction controller based on images corresponding to the indoor space and captured by the camera. The controller may be configured to determine an activity level of an occupant for each of a plurality of areas of the indoor space based on a plurality of images corresponding to the indoor space; determine a direction of air discharged from the plurality of outlets based on the determined activity level; and control the airflow direction controller according to the direction of the air which is determined for the plurality of outlets.
