Hvac controller with integrated airside and waterside control

A method for controlling a building heating, ventilating, or air conditioning (HVAC) system comprising waterside HVAC equipment configured to generate a heated or chilled fluid and airside HVAC equipment configured to use the heated or chilled fluid to heat or cool a supply airflow provided to a building, the method comprising:

• performing an integrated airside/waterside control process to determine control outputs for both the waterside HVAC equipment and the airside HVAC equipment simultaneously such that the control outputs for the airside HVAC equipment are based on the control outputs for the waterside HVAC equipment and vice versa;
• and
• operating the waterside HVAC equipment and the airside HVAC equipment to provide heating or cooling to the building using the control outputs.

A controller for a building heating, ventilating, or air conditioning (HVAC) system that uses both waterside HVAC equipment and airside HVAC equipment to heat or cool a supply airflow provided to a building, the controller comprising one or more processing circuits configured to:

• perform an integrated airside/waterside control process to determine control outputs for both the waterside HVAC equipment and the airside HVAC equipment simultaneously such that the control outputs for the airside HVAC equipment are based on the control outputs for the waterside HVAC equipment and vice versa;
• and
• operate the waterside HVAC equipment and the airside HVAC equipment to heat or cool the supply airflow using the control outputs.
