Abstract

The present disclosure relates to systems and methods for mapping a building space using wearable devices in order to better control the comfort level in the building. In some instances, a system compiles information such as temperature information that is provided by an individual'"'"'s wearable device as the individual moves about the building over time. Using this data, the system may create and/or update a comfort map of the building, which can be used to determine how various rooms of the building heat and cool over time, as well as usage pattern of the various rooms of the building. The system can then use the comfort map of the building to better control one or more comfort sources of the building.

Claims

1. A method of mapping comfort conditions within a building space, one or more individuals having wearable sensors in the building space, the method comprising:

obtaining a measure of comfort at a wearable sensor, the measure of comfort including an air temperature;

transmitting the measure of comfort from the wearable sensor to a controller configured to actuate a global comfort source and/or one or more local comfort sources;

determining, by triangulating between a plurality of wireless beacons, a spatial location of the wearable sensor in the building space corresponding to when the measure of comfort was obtained, and a time corresponding to when the measure of comfort was obtained, wherein the building space includes two or more stories, wherein the spatial location is given by three spatial dimensions (x, y and z), and wherein the spatial location is indicative of a story of the two or more stories;

incorporating the measure of comfort, the corresponding time and the corresponding spatial location of the wearable sensor in the building space into a three-dimensional comfort map of the building space maintained by the controller to correlate the measure of comfort with the corresponding spatial location and the corresponding time;

repeating the obtaining, transmitting, determining and incorporating steps as the one or more individuals having the wearable sensors move spatially about the building space in at least two spatial dimensions to populate the three-dimensional comfort map over time, wherein the three-dimensional comfort map, once populated, records a history of the measure of comfort for each of two or more different spatial locations in the building space; and

actuating, by the controller, the global comfort source and/or the one or more local comfort sources based at least in part on the three-dimensional comfort map of the building space.

2. The method of claim 1, further comprising analyzing changes in the three-dimensional comfort map of the building space over time in order to detect one or more patterns in how different spatial locations of the building space performs over time.

3. The method of claim 2, further comprising actuating the global comfort source and/or the one or more local comfort sources based at least in part on the one or more detected patterns in how different spatial locations of the building space performs over time.

4. The method of claim 1, further comprising analyzing the location of the wearable sensor over time to detect one or more patterns in how the wearable sensor moves through the building space over time.

5. The method of claim 4, further comprising actuating the global comfort source and/or the one or more local comfort sources based at least in part on the one or more detected patterns in how the wearable sensor moves through the building space over time.

6. The method of claim 1, wherein the wearable sensor is configured to communicate with the controller via a wireless communications protocol.

7. The method of claim 6, wherein at least some of the plurality of wireless beacons are disposed within the one or more local comfort sources.

8. The method of claim 6, wherein at least some of the plurality of wireless beacons comprise wireless beacons separate from the one or more local comfort sources.

9. The method of claim 1, further comprising obtaining and populating the three-dimensional comfort map with external weather data.

10. A building comfort controller for controlling comfort within a building space, the building comfort controller comprising:

a memory for storing a three-dimensional comfort map of the building space that provides a history of how various portions of the building space perform over time based upon comfort data provided by a wearable sensor moving about the building space in at least three spatial directions, the three-dimensional comfort map including a plurality of map entries, wherein each map entry includes;

(1) a comfort data value from the wearable sensor including the air temperature;

(2) a time that corresponds to when the comfort data value was obtained; and

(3) a spatial location within the building space that corresponds to when the comfort data value was obtained;

an input for receiving comfort data from the wearable sensor as well as spatial location data regarding the spatial location within the building of the wearable sensor;

an output for sending control instructions to one or more comfort sources;

a controller operably coupled to the memory, the input and the output, the controller configured to;

update the three-dimensional comfort map of the building space over time using comfort data received from the wearable sensor over time, as well as the corresponding time and spatial location;

determine the spatial location of the wearable sensor by triangulating the wearable sensor between a plurality of wireless beacons, wherein the building space includes two or more stories, wherein the spatial location is given by three spatial dimensions (x, y and z), and wherein the spatial location is indicative of a story of the two or more stories; and

provide control instructions for controlling the one or more comfort sources based at least in part on the three-dimensional comfort map of the building space.

11. The building comfort controller of claim 10, wherein the one or more comfort sources comprise a controllable damper.

12. The building comfort controller of claim 10, wherein the one or more comfort sources comprise one or more localized comfort sources and one or more global comfort sources.

13. The building comfort controller of claim 12, wherein the one or more global comfort sources comprises a central HVAC system installed within the building space, and the one or more localized comfort sources comprises one or more of a gas fireplace, an electric fireplace, a space heater, an electric blanket, a ceiling fan, a floor fan, a table fan, or a window air conditioner.

14. The building comfort controller of claim 10, wherein the controller is configured to accept a floor plan uploaded via the input and to incorporate the floor plan into the three-dimensional comfort map of the building space.

15. A building space comfort system for controlling comfort within a building space, the building space comfort system comprising:

a plurality of wireless beacons disposed throughout the building space, the plurality of wireless beacons enabling triangulation of wireless signals from one or more wearable sensors in order to determine a spatial location of each of the one or more wearable sensors within the building space;

a comfort controller configured to collect a plurality of measures of comfort over time from one or more of the wearable sensors worn or otherwise carried by one or more individuals within the building space including an air temperature, along with the corresponding spatial location of the one or more of the wearable sensors and the corresponding time of collection, wherein the spatial location is given by three spatial dimensions (x, y and z), the comfort controller further configured to maintain a three-dimensional comfort map of the building space that includes a plurality of map entries, wherein the building space includes two or more stories, wherein the spatial location of the one or more wearable sensors is indicative of a story of the two or more stories, and wherein each map entry includes one of the plurality of measures of comfort collected from the one or more wearable sensors along with the corresponding spatial location and the corresponding time; and

a global and/or local comfort source operably coupled to the comfort controller, the comfort controller configured to control the global and/or local comfort source based, at least in part, on the three-dimensional comfort map of the building space.
