1. A method of optimizing energy consumption of a heating, ventilation, and air conditioning (HVAC) system, comprising:
controlling, via a thermostat, the HVAC system during a predetermined time period according to a first setpoint schedule comprising one or more first setpoints;
monitoring, via the thermostat, a first cumulative runtime of the HVAC system during a first time period of the predetermined time period;
determining that the first cumulative runtime of the HVAC system during the first time period has met a first predefined HVAC runtime threshold criterion;
after determining that the first cumulative runtime of the HVAC system during the first time period has met the first predefined HVAC runtime threshold criterion, generating a second setpoint schedule for a second time period of the predetermined time period comprising one or more second setpoints to decrease energy usage by the HVAC system compared to the first setpoint schedule for the second time period; and
controlling, via the thermostat, the HVAC system during the second time period according to the second setpoint schedule, wherein the second time period occurs after the first time period.
