1. A building management system (BMS) configured to generate predictive models used to forecast time series values of building variables monitored by the BMS, the BMS comprising:

  • one or more sensors configured to measure time series values of the building variables;

    a deterministic model generator configured to use historical BMS data comprising historical values for the time series of building variables to train one or more deterministic models that predict deterministic values for the time series;

    a stochastic model generator configured to use differences between actual values for the time series and the deterministic values predicted by the one or more deterministic models to train a stochastic model that predicts a stochastic value for the time series;

    a forecast adjuster configured to adjust the deterministic values predicted by the one or more deterministic models using the stochastic value predicted by the stochastic model to generate an adjusted forecast for the time series;

    a demand response optimizer configured to use the adjusted forecast for the time series to generate an optimal set of control actions for building equipment; and

    building equipment configured to use the optimal set of control actions to affect one or more of the building variables monitored by the BMS by operation of the building equipment.
