An Energy Management Process and Prediction of Energy Use in an Office Building

The purpose of this study was to propose a building energy management process, verify the proposed model by applying energy management techniques in a real office building, and develop an empirical approach for predicting building energy use with regression analysis. This study proposed the four major energy management steps: energy audit, energy analysis, identifying and evaluating the energy saving opportunities, and retrofit implementation and follow-through. For the prediction of energy use, simple regression models were developed based on historical energy consumption data as a function of daily outside temperatures, while the predicting equations were derived for different operational modes and day types. By selecting a real building as a case study, the feasibilities of the building energy management process and the empirical approach for predicting building energy use have been examined.
