A performance diagnosis device performs data collection of operation data of an air conditioner, and a model database indicates performance corresponding to each operating condition of the air conditioner. The device uses the operation data and the model database to obtain reference data that is a combination of a plurality of operating conditions and a reference value. A performance evaluation unit compares the reference data and evaluation data that is to be evaluated, and evaluates the performance of the air conditioner. A reference data update unit compares the reference data and the evaluation data when the operating conditions match with each other, and updates the reference data. As a result, the deterioration diagnosis technology can update unique reference values that reflect the dimensional errors of each device, differences in installation conditions, and differences in operating conditions to appropriate values with respect to the deterioration of the performance of air conditioners.

A building management system (BMS) provides feedback to a user via a user interface to assist the user in configuring the BMS. It can be challenging for new or less experienced users to understand all of the actions they are performing when configuring a BMS. The feedback presented via the user interface includes graphical and textual feedback to alert the user of actions performed when applying tags. The feedback identifies one or more missing requirements associated with the tags. The feedback presented via the user interface also includes textual summaries of control sequences configured using the BMS. The textual summaries include descriptions of control sequences and instructions for properly configuring the building equipment.

A thermostat for a building zone includes at least one of a model predictive controller and an equipment controller. The model predictive controller is configured to obtain a cost function that accounts for a cost of operating HVAC equipment during each of a plurality of time steps, use a predictive model to predict a temperature of the building zone during each of the plurality of time steps, and generate temperature setpoints for the building zone for each of the plurality of time steps by optimizing the cost function subject to a constraint on the predicted temperature. The equipment controller is configured to receive the temperature setpoints generated by the model predictive controller and drive the temperature of the building zone toward the temperature setpoints during each of the plurality of time steps by operating the HVAC equipment to provide heating or cooling to the building zone.

A non-transitory computer-readable storage medium for a heating, ventilation, and/or air conditioning (HVAC) system includes instructions that, when executed by a processor, cause the processor to receive an input indicative of a user location, perform a verification that the user location is within a determined distance from the HVAC system, and control access to system settings of the HVAC system based on the verification.
