Thermostat with predictive variable air volume (vav) performance features

A method for predicting a performance of building equipment and controlling the building equipment via a thermostat, the method comprising:

• operating the building equipment to control an environmental condition within a building comprising a first zone and one or more second zones;
• receiving a first time-series data set for a parameter of a first piece of the building equipment associated with the first zone;
• receiving one or more second time-series data sets for the parameter of one or more second pieces of building equipment associated with the one or more second zones, wherein the first piece of building equipment and the one or more second pieces of building equipment are a same type of building equipment;
• performing a comparison comprising comparing the first time-series data set with the one or more second time-series data sets;
• and
• generating one or more recommendations for improving the performance of the first piece of building equipment based on the comparison of the first time-series data set with the one or more second time-series data sets.

A building controller for predicting a performance of building equipment and controlling the building equipment, the controller comprising a processing circuit configured to:

• operate the building equipment to control an environmental condition within a building comprising a first zone and one or more second zones;
• receive a first time-series data set for a parameter of a first piece of building equipment associated with the first zone;
• receive one or more second time-series data sets for the parameter of one or more second pieces of building equipment associated with the one or more second zones, wherein the first piece of building equipment associated with the first zone is a first variable air volume (VAV) box configured to receive air from an air handler unit (AHU), wherein the one or more second pieces of building equipment associated with the one or more second zones are one or more second VAV boxes configured to receive air from the AHU;
• performing a comparison comparing the first time-series data set with the one or more second time-series data sets;
• and
• generate one or more recommendations for improving the performance of the first piece of building equipment based on the comparison of the first time-series data set with the one or more second time-series data sets.
