1. A method of controlling an environmental maintenance system that includes a plurality of actuators and a plurality of sensors, each sensor measuring a value of a physical condition of an environment, the method comprising:

  • receiving sensor values S corresponding to the sensors, the sensor values S corresponding to operational levels U1 of the actuators;

    receiving new operational levels U2 of the actuators, where U2

    U1=dU;

    predicting a change dS in the sensor values S, the change dS corresponding to the change dU, wherein the prediction is performed in accordance with a transfer model;

    operating the actuators with the new operational levels U2;

    subsequently, measuring new sensor values Snew;

    repeating the receiving, prediction, operation, and subsequent measurement at a plurality of times;

    determining a metric of an accuracy of the transfer model by comparing the predicted sensor values to the measured sensor values;

    receiving a proposed change to the operation levels of the actuators, the proposed change being based on the transfer model;

    based on the accuracy metric, adjusting the proposed change to the operation levels of the actuators; and

    setting the operation levels of the actuators based on the adjustment to the proposed change.
