This master's thesis focuses on data processing and analysis within the Energy Management System (EnMS) at the Brno University of Technology (BUT). The first part of the thesis summarizes applicable methods for time series forecasting. Based on the specific requirements of the EnMS, the SARIMAX method was selected. This model was used to evaluate the impact of operational parameters (academic calendar, temperature) and to forecast electricity consumption. For large consumption units (main supply lines), it achieved high accuracy with a MAPE of under 10 %. The acquired findings were further applied to design algorithms for real-time anomaly detection and monitoring of quarter-hourly maximums. All developed models were designed to allow their implementation into the BUT EnMS. The proposed solution provides the university with a tool to make building operations more efficient, gain a deeper understanding of energy consumption, and reduce financial costs.
