Building management system with supervisory fault detection layer

One or more non-transitory computer-readable media having computer-executable instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving time series data characterizing an operating performance of one or more BMS devices;
• processing the time series data using multiple different fault detection methods to generate multiple fault detection results;
• providing the multiple fault detection results as outputs from the multiple different fault detection methods;
• and
• applying the multiple fault detection results as inputs to a neural network that determines whether the multiple fault detection results are indicative of a fault condition in the BMS.

A 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:

• receiving time series data characterizing an operating performance of one or more BMS devices;
• processing the time series data using multiple different fault detection methods to generate multiple fault detection results;
• providing the multiple fault detection results as outputs from the multiple different fault detection methods;
• and
• applying the multiple fault detection results as inputs to a neural network that determines whether the multiple fault detection results are indicative of a fault condition in the BMS.
