1. A method for controlling HVAC equipment for a building, comprising:
generating, based on historical building data, a discomfort tolerance defining an acceptable amount of occupant discomfort;
determining a first value of an environmental condition by predicting that the occupant discomfort would exceed the discomfort tolerance in a first direction at the first value of the environmental condition;
determining a second value of the environmental condition by predicting that the occupant discomfort would exceed the discomfort tolerance in a second direction opposite the first direction at the second value of the environmental condition; and
operating the HVAC equipment to maintain the environmental condition between the first value and the second value.
