1. A method for building equipment comprising at least one of heating, ventilation, or air conditioning (HVAC) equipment, lighting equipment, security equipment, or fire safety equipment, the method comprising:
automatically selecting a prediction horizon used by a predictive model for the building equipment by performing evaluations of model performance at successively narrower ranges of possible prediction horizons and choosing the successively narrower ranges by choosing higher ranges in response to successful results of the evaluations and choosing lower ranges in response to unsuccessful results of the evaluations until the prediction horizon is determined;
using the predictive model with the prediction horizon to generate predicted behavior of the building equipment based at least on current measurements of a set of variables related to the building equipment and perform an automated control action comprising generating control signals for the building equipment based on the predicted behavior of the building equipment generated using the predictive model; and
affecting the predicted behavior of the building equipment by applying the control signals to the building equipment.
