Environmental setpoint for HVAC system control

A computer implemented method, comprising:

• receiving, by a controller of an HVAC system, a user-preferred temperature setpoint for a building space;
• determining, by the controller, a value of an environmental variable either internal to or external to the building space;
• projecting, by the controller, an energy usage amount for the user-preferred energy setpoint based on the value of the environmental variable;
• generating, by the controller, a user comfort score for the user-preferred energy setpoint based on the value of the environmental variable;
• based on the projected energy usage amount and the user comfort score, generating, by the controller, an overall score for the user-preferred temperature setpoint;
• and
• presenting, by the controller, the user with a setpoint scoring interface including the overall score.

A non-transitory computer readable media having computer-executable instructions embodied therein that, when executed by a processor of a thermostat, cause the thermostat to perform operations to control a temperature of a building space, the operations including:

• comparing a user-preferred temperature setpoint to a measured air temperature;
• projecting an energy usage amount for the user-preferred energy setpoint in response to the comparison;
• generating a user comfort score for the user-preferred energy setpoint in response to the comparison;
• generating an overall score for the user-preferred temperature setpoint in response to the projected energy usage amount and the user comfort score;
• and
• display on the thermostat a setpoint scoring interface including the overall score.
