1. A method of decreasing energy consumption, comprising:

  • accessing, by a computer processing system, a temperature setpoint schedule for a thermostat that controls an HVAC system that environmentally conditions an enclosure, the temperature setpoint schedule defining a plurality of temperature setpoints over a time period;

    for each periodic time interval of a succession of periodic time intervals, generating, by the computer processing system, an adjusted version of the accessed temperature setpoint schedule, wherein;

    the adjusted version of the temperature setpoint schedule comprises one or more incremental changes being made to at least a subset of the plurality of temperature setpoints; and

    the one or more incremental changes each correspond to less energy usage by the HVAC system during one of the periodic time intervals of the succession of periodic time intervals as compared to a previous one of the periodic time intervals;

    for each time interval of the succession of time intervals, determining that a user change to the incrementally adjusted version of the temperature setpoint schedule has not been received via a user input component of the thermostat nor via a computerized access device that communicates with the thermostat via a remote energy management system, wherein;

    the thermostat comprises a wireless communication interface that communicates with the remote energy management system; and

    the thermostat comprises a wired communication interface in wired communication with the HVAC system; and

    for each time interval of the succession of time intervals, controlling, by the thermostat, the HVAC system according to the incrementally adjusted version of the temperature setpoint schedule generated for the corresponding periodic time interval at least partially in response to the user change not being received via the user input component of the thermostat nor via the computerized access device that communicates with the thermostat via the remote energy management system.
