Abstract

Systems and methods are provided for monitoring and controlling one or more environmental conditions of a building. The method comprises obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building. The method further comprises combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day. The method finally comprises operating HVAC equipment to drive the combined feedback toward a setpoint for the building.

Claims (56)

1. A method for monitoring and controlling one or more environmental conditions of a building, the method comprising:

obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building;

combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day;

operating HVAC equipment to drive the combined feedback toward a setpoint for the building.

2. The method of claim 1 , further comprising:

determining a predicted occupancy of the first location and the second location based on the time of day; and

adjusting at least one of the weight of the feedback from the first sensor or the weight of the feedback from the second sensor using the predicted occupancy.

3. The method of claim 1 , further comprising:

determining a difference between the feedback from the first sensor and the feedback from the second sensor; and

operating the HVAC equipment to reduce the difference between the feedback from the first sensor and the feedback from the second sensor in response to the difference reaching a threshold.

4. The method of claim 3 , wherein the HVAC equipment comprises a recirculation fan and operating the HVAC equipment comprises operating the recirculation fan to reduce the difference between the feedback from the first sensor and the difference from the second sensor.

5. The method of claim 1 , further comprising:

comparing the feedback from the first sensor to a threshold; and

operating the HVAC equipment using the feedback from the first sensor without considering the feedback from the second sensor in response to the feedback from the first sensor reaching the threshold.

6. The method of claim 1 , further comprising:

identifying at least one of an importance of the first location or an importance of the second location;

adjusting at least one of the weight of the feedback from the first sensor or the weight of the feedback from the second sensor using the importance of the first location or the importance of the second location.

7. The method of claim 1 , further comprising:

determining that the first location is more important than the second location; and

operating the HVAC equipment in a manner predicted to move the feedback from the first sensor toward the setpoint and move the feedback from the second sensor away from the setpoint in response to determining that the first location is more important than the second location.

8. A method for monitoring and controlling one or more environmental conditions of a building, the method comprising:

obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building;

identifying an importance of the first location and an importance of the second location;

operating HVAC equipment in a manner predicted to move the feedback from the first sensor toward a setpoint for the building and move the feedback from the second sensor away from the setpoint in response to determining that the first location is more important than the second location.

9. The method of claim 8 , further comprising:

combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on at least one of the importance of the first location or the importance of the second location; and

operating the HVAC equipment to drive the combined feedback toward the setpoint for the building.

10. The method of claim 8 , wherein operating the HVAC equipment comprises exchanging air between the first location and the second location in response to predicting that exchanging the air between the first location and the second location will move the feedback from the first sensor toward the setpoint.

11. The method of claim 8 , further comprising:

combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day; and

operating the HVAC equipment to drive the combined feedback toward the setpoint for the building.

12. The method of claim 8 , further comprising:

determining a difference between the feedback from the first sensor and the feedback from the second sensor; and

operating the HVAC equipment to reduce the difference between the feedback from the first sensor and the feedback from the second sensor in response to the difference reaching a threshold.

13. The method of claim 12 , wherein the HVAC equipment comprises a recirculation fan and operating the HVAC equipment comprises operating the recirculation fan to reduce the difference between the feedback from the first sensor and the difference from the second sensor.

14. The method of claim 8 , further comprising:

comparing the feedback from the first sensor to a threshold; and

operating the HVAC equipment using the feedback from the first sensor without considering the feedback from the second sensor in response to the feedback from the first sensor reaching the threshold.

15. A method for monitoring and controlling one or more environmental conditions of a building, the method comprising:

obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building;

determining a difference between the feedback from the first sensor and the feedback from the second sensor; and

operating HVAC equipment to reduce the difference between the feedback from the first sensor and the feedback from the second sensor in response to the difference reaching a threshold.

16. The method of claim 15 , wherein the HVAC equipment comprises a recirculation fan and operating the HVAC equipment comprises operating the recirculation fan to reduce the difference between the feedback from the first sensor and the feedback from the second sensor.

17. The method of claim 15 , further comprising:

combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day; and

operating the HVAC equipment to drive the combined feedback toward a setpoint for the building.

18. The method of claim 15 , further comprising:

identifying at least one of an importance of the first location or an importance of the second location;

combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on at least one of the importance of the first location or the importance of the second location; and

operating the HVAC equipment to drive the combined feedback toward a setpoint for the building.

19. The method of claim 15 , further comprising:

determining that the first location is more important than the second location; and

operating the HVAC equipment in a manner predicted to move the feedback from the first sensor toward a setpoint for the building and move the feedback from the second sensor away from the setpoint in response to determining that the first location is more important than the second location.

20. The method of claim 15 , further comprising:

comparing the feedback from the first sensor to a threshold; and

operating the HVAC equipment using the feedback from the first sensor without considering the feedback from the second sensor in response to the feedback from the first sensor reaching the threshold.
