Claim 0:
1. A heating, ventilation, and air conditioning (HVAC) fault prediction system for a building, comprising one or more processors and one or more memory devices, the one or more memory devices having instructions stored thereon that, when executed by the one or more processors, cause the one or more processors to:
receive HVAC data relating to a plurality of HVAC components, the HVAC data indicating performance of the plurality of HVAC components;
generate, based on the HVAC data, a univariate prediction model and a multivariate prediction model;
generate, using the HVAC data, one or more predicted operational parameters for the plurality of HVAC components corresponding to a future time period;
execute at least one of the univariate prediction model or the multivariate prediction model on the one or more predicted operational parameters to predict a HVAC fault associated with at least one of the plurality of HVAC components to occur during the future time period; and
cause a change in operations of the plurality of HVAC components to prevent the predicted HVAC fault, the change comprising at least one of maintenance or repair, adjustment of a setpoint used by at least one of the plurality of HVAC components, or disabling at least one of the plurality of HVAC components.
