Accurate forecasting in commercial and industrial buildings can serve many purposes. It can detect anomalous behavior that deviates beyond an expected range (Figure 2). This activity may signal the need to inspect equipment or an unexpected outage. It also enables the ability to create dynamic setpoints for building operation. Demand management is a method to manage peak demand costs and executes based on demand forecasts. The forecast anticipates high demand events so that corrective action can be predetermined (Figure 3). Some examples include throttling non-critical ventilation, dynamic chiller operation, and efficiency optimization.
