Model predictive maintenance system with event or condition based performance

A method for determining optimal maintenance of building equipment, the method comprising:

• at a first time, predicting a future state of the building equipment predicted to occur at a second time after the first time;
• obtaining one or more performance indicators for the building equipment indicating an actual state of the building equipment at a second time;
• determining whether a trigger condition has been satisfied based on the one or more performance indicators by comparing the actual state of the building equipment at the second time with the predicted future state of the building equipment predicted to occur at the second time;
• triggering a model predictive maintenance process to generate a maintenance schedule for the building equipment and operating decisions for the building equipment in response to determining that the trigger condition has been satisfied, wherein the model predictive maintenance process comprises:
• predicting a resource consumption of the building equipment over an optimization period as a function of an estimated degradation state of the building equipment;
• defining a cost of operating the building equipment over the optimization period as a function of the predicted resource consumption;
• defining a cost of performing maintenance on the building equipment over the optimization period as a function of the maintenance schedule for the building equipment;
• and
• optimizing an objective function including the cost of operating the building equipment and the cost of performing maintenance on the building equipment to determine the maintenance schedule;
• initiating a maintenance activity for the building equipment in accordance with the maintenance schedule;
• and
• controlling the building equipment by generating electronic control signals based on the operating decisions for the building equipment and causing the building equipment to affect a variable state or condition in a building using the electronic control signals.

A model predictive maintenance (MPM) controller for building equipment, the MPM controller comprising:

• one or more processing circuits comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• determining whether a trigger condition has been satisfied based on one or more time-varying inputs to the MPM controller and at least one time-varying threshold;
• and
• triggering a model predictive maintenance process to generate a maintenance schedule for the building equipment and operating decisions for the building equipment in response to determining that the trigger condition has been satisfied, wherein the model predictive maintenance process comprises:
• predicting a resource consumption of the building equipment over an optimization period as a function of an estimated degradation state of the building equipment;
• defining a cost of operating the building equipment over the optimization period as a function of the predicted resource consumption;
• defining a cost of performing maintenance on the building equipment over the optimization period as a function of the maintenance schedule for the building equipment;
• and
• optimizing an objective function including the cost of operating the building equipment and the cost of performing maintenance on the building equipment to determine the maintenance schedule;
• and
• initiating a maintenance activity for the building equipment in accordance with the maintenance schedule;
• and
• controlling the building equipment by generating electronic control signals based on the operating decisions for the building equipment and causing the building equipment to affect a variable state or condition in a building using the electronic control signals.
