This specification relates to a central control apparatus, which is configured to calculate time-division power usage as predicted power usage, which is consumed by at least one facility in a control area within a specific time section, on the basis of predicted external temperature corresponding to the control area within the specific time section and a time-division model, calculate variable-based degree day (VBDD) daily power usage as predicted daily power usage corresponding to the control area on the basis of the predicted external temperature and a VBDD model, and calculate final power usage as final predicted power usage consumed in the control area within the specific time section on the basis of the time-division power usage and the VBDD daily power usage, and a facility control system including the same.
