Abstract

Systems and methods for control optimization of building subsystems are disclosed. In some embodiments, a system comprises at least one processor; and memory storing instructions executable by the at least one processor, the instructions when executed cause the system to: obtain building load information, the building load information related to one or more power consuming subsystems of the building; determine a future building load based on the building load information; and adjust one or more setpoint tolerances for the one or more subsystems based on the determined future building load.

Claims (41)

1. A system for control optimization of building subsystems, the system comprising:

at least one processor;

a controller configured to send control signals to a component outside of the system to adjust one or more setpoint tolerances for one or more power consuming subsystems; and

memory storing instructions executable by the at least one processor, the instructions when executed cause the system to:

obtain building load information, the building load information related to the one or more power consuming subsystems of the building;

determine a future building load based on the building load information; and

adjust the one or more setpoint tolerances for the one or more subsystems based on the determined future building load.

2. The system of claim 1 , wherein the instructions further cause the system to:

obtain occupancy information for the building, the future building load based on the occupancy information and the building load information.

3. The system of claim 2 , wherein the instructions further cause the system to:

determine a future occupancy for the building based on the occupancy information, and wherein determining of the future building load for the building is further based on the determined future occupancy.

4. The system of claim 1 , wherein the instructions further cause the system to:

determine a power source for powering the one or more subsystems based on the determined future building load, wherein adjusting of the one or more or more setpoint tolerances is further based on the determined power source.

5. The system of claim 4 , wherein:

determining of the future building load comprises generating a building load forecast for a given period of time, and wherein

determining of the power source comprises generating a power source forecast for the given period of time, and wherein

the instructions further cause the system to adjust the one or more setpoint tolerances for the given period of time.

6. The system of claim 4 , wherein the instructions further cause the system to:

determine an adjustment amount for the one or more setpoint tolerances based on the determined power source.

7. The system of claim 4 , wherein the instructions further cause the system to:

generate a recommendation for the determined power source; and

responsive to a user accepting the recommendation, adjust the one or more setpoint tolerances.

8. A method for control optimization of building subsystems, the method being implemented in a system comprising at least one processor, a controller configured to send control signals to a component outside of the system to adjust one or more setpoint tolerances for one or more power consuming subsystems, and memory storing instructions, the method comprising:

obtaining building load information, the building load information related to the one or more power consuming subsystems of the building;

determining a future building load based on the building load information; and

adjusting the one or more setpoint tolerances for the one or more subsystems based on the determined future building load.

9. The method of claim 8 , further comprising:

obtaining occupancy information for the building, the future building load based on the occupancy information and the building load information.

10. The method of claim 9 , further comprising:

determining a future occupancy for the building based on the occupancy information, and wherein determining the future building load for the building is further based on the determined future occupancy.

11. The method of claim 8 , further comprising:

determining a power source for powering the one or more subsystems based on the determined future building load, wherein adjusting the one or more or more setpoint tolerances is further based on the determined power source.

12. The method of claim 11 , wherein

determining the future building load comprises generating a building load forecast for a given period of time, and wherein

determining the power source comprises generating a power source forecast for the given period of time, and wherein the method further comprises:

adjusting the one or more setpoint tolerances for the given period of time.

13. The method of claim 11 , further comprising:

determining an adjustment amount for the one or more setpoint tolerances based on the determined power source.

14. The method of claim 12 , further comprising:

generating a recommendation for the determined power source; and

responsive to a user accepting the recommendation, adjusting the one or more setpoint tolerances.
