Abstract

A method of conditioning an environment includes generating, by a group feedback analysis system, a first comfort limit based on a first plurality of data points corresponding to user feedback of a group of users in an environment conditioned by an environmental conditioning system to identify the first comfort limit at a first extreme; generating, by the group feedback analysis system, a second comfort limit based on a second plurality of data points corresponding to user feedback of the group of users in the environment conditioned by the environmental conditioning system to identify the second comfort limit at a second extreme, the second extreme being opposite the first extreme; identifying, by the group feedback analysis system, a comfort region defined by the first comfort limit and the second comfort limit; and controlling the environmental conditioning system to maintain at least one environmental criterion within the comfort region.

Claims

1. A method of conditioning an environment, comprising:

generating, by a group feedback analysis system, a first comfort limit based on a first plurality of data points corresponding to user feedback of a group of users in an environment conditioned by an environmental conditioning system to identify the first comfort limit at a first extreme of at least one environmental criterion;

generating, by the group feedback analysis system, a second comfort limit based on a second plurality of data points corresponding to user feedback of the group of users in the environment conditioned by the environmental conditioning system to identify the second comfort limit at a second extreme of the at least one environmental criterion, the second extreme being opposite the first extreme;

identifying, by the group feedback analysis system, a comfort region defined by the first comfort limit and the second comfort limit;

assigning a weight to each user input making up the user feedback of the group of users, wherein the weight is assigned based on a number of complaints, defined as user feedback inputs indicating discomfort, generated by a user; and

controlling the environmental conditioning system to maintain at least one environmental criterion within the comfort region;

wherein generating the first comfort limit comprises analyzing the first plurality of data points to identify outliers, and forming the first comfort and second comfort limit to exclude the outliers;

wherein identifying outliers comprises determining a time at which the user feedback was received and identifying the outlier in response to at least one of (i) the time at which the user feedback was received and (ii) the proximity in time between a first user feedback and a second user feedback from a single user.

2. The method of claim 1, further comprising:

receiving, at a user input device, a user input registering a comfort level of a user;

identifying a value of the environmental criterion associated with an environment of the user and the user input as being an outlier relative to one or both of the first and second comfort limits; and

disregarding the user input based on identifying the value of the environmental criterion as being an outlier.

3. The method of claim 1, further comprising:

receiving, at a user input device, a user input registering a comfort level of a user;

identifying a value of the environmental criterion associated with an environment of the user and the user input as being an outlier relative to one or both of the first and second comfort limits; and

providing feedback to the user at the user input device indicating that the value of the environmental criterion associated with the environment of the user is an outlier.

4. The method of claim 3, further comprising:

generating a prompt on the user input device to prompt the user to change the user input to correspond to a different value of the environmental criterion.

5. The method of claim 1, wherein the at least one environmental criterion includes a plurality of environmental criteria, including at least temperature and humidity of the environment.

6. The method of claim 5, wherein the first comfort limit and the second comfort limit are two-dimensional curves that represent a combination of the plurality of environmental criteria.

7. The method of claim 1, wherein the weight is further assigned based on (i) an identity of the user associated with the user input and (ii) a duration of time that the user is in an environment associated with the user.

8. The method of claim 1, wherein generating the first and second comfort limits comprises:

receiving a plurality of user inputs to a plurality of user input devices;

sensing values of the environmental criterion in one or more enclosed environments based on the plurality of user inputs;

associating the user inputs with sensed values of the environmental criterion; and

generating the first and second comfort limits based on the sensed values of the environmental criterion.

9. An environmental control system, comprising:

a feedback analysis system configured to receive feedback from a group of users corresponding to a comfort level of the group of users in a group environment in which the group of users is located, to generate data including a first comfort limit and a second comfort limit, the first comfort limit corresponding to the feedback from the group of users at a first extreme of an environmental criterion and the second comfort limit corresponding to the feedback from the group of users at a second extreme of the environmental criterion opposite the first extreme, and the feedback analysis system further configured to identify a comfort region bounded by the first comfort limit and the second comfort limit and to generate control signals for an environmental conditioning system to maintain the group environment within the comfort region;

the feedback analysis system configured to assign a weight to each user input making up the user feedback of the group of users, wherein the weight is assigned based on a number of complaints, defined as user feedback inputs indicating discomfort, generated by a user;

wherein the feedback analysis system is configured to identify outlier user feedback data points and to form the first and second comfort limits to exclude the outlier user feedback data points;

wherein identifying outliers comprises determining a time at which the user feedback was received and identifying the outlier in response to at least one of (i) the time at which the user feedback was received and (ii) the proximity in time between a first user feedback and a second user feedback from a single user.

10. The environmental control system of claim 9, further comprising an environmental conditioning system for conditioning the environmental criterion in the group environment based on the control signals from the feedback analysis system.

11. The environmental control system of claim 10, wherein the environmental criterion is a characteristic of air in the group environment, and the environmental conditioning system is configured to condition the characteristic of the air based on the control signals from the feedback analysis system.

12. The environmental control system of claim 9, further comprising:

one or more user input devices to receive inputs from users registering a comfort level of the users,

wherein the feedback analysis system is configured to generate user feedback data points by identifying a value of the environmental criterion associated with an environment of the users based on the inputs received from the users, to identify the user feedback data points as being outliers relative to one or both of the first and second comfort limits based on the user feedback data points being located outside a predetermined range of the first or second comfort limits, and to disregard user feedback data points based on identifying user feedback entries as being outliers.

13. The environmental control system of claim 9, further comprising:

one or more user input devices to receive inputs from users registering a comfort level of the users,

wherein the feedback analysis system is configured to generate user feedback data points by identifying a value of the environmental criterion associated with the inputs received from the users, to identify the user feedback data points as being outliers relative to one or both of the first and second comfort limits based on the user feedback data points being located outside a predetermined range of the first or second comfort limits, and to provide feedback to the users at the user input devices indicating that the user feedback data points are outliers.

14. The environmental control system of claim 13, wherein the feedback analysis system is further configured to generate a prompt on the user input devices to prompt the users to change the user inputs to correspond to different values of the environmental criterion based on determining that the user feedback data points are outliers.
