Classification: CPC G  F  Y | IPC F  G

Claim 7:
8. A controller for heating, ventilation, or air conditioning (HVAC) equipment operable to affect an environmental condition of a building, the controller comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
obtaining one or more predictive models configured to predict values of a sustainability control objective and another control objective as a function of control decision variables for the HVAC equipment, the sustainability control objective comprising an amount of carbon emissions predicted to result from operating the HVAC equipment in accordance with the control decision variables, the other control objective comprising an indication of infection risk that results from a predicted concentration of airborne infectious quanta, the indication of infection risk predicted by an infectious quanta model as a function of the control decision variables;
executing an optimization process using the one or more predictive models to produce multiple sets of optimization results corresponding to different values of the control decision variables, the sustainability control objective, and the other control objective;
selecting one or more of the sets of optimization results for which the values of the sustainability control objective and the other control objective are not both improved by another of the sets of optimization results;
providing a user interface comprising multiple selectable control plan options corresponding to the multiple sets of optimization results, the user interface comprising for each of the multiple selectable control plan options: (i) a set of the values of the control decision variables for a corresponding set of the optimization results and (ii) a set of values of the sustainability control objective and the other control objective predicted to result from the set of values of the control decision variables for the corresponding set of optimization results; and
operating the HVAC equipment to affect the environmental condition of the building in accordance with the values of the control decision variables corresponding to a control plan option of the multiple selectable control plan options selected via the user interface.
