Normalization Method of Building’s Actual Energy Consumption for Normalized Building Energy Benchmarking
Young-Seo Yoo, Deuk-Woo Kim, Dong-Hyuk Yi, Cheol-Soo ParkDOI: https://doi.org/10.13124/9788860462022_05Abstract: Energy use intensity (EUI, kWh/m2·yr) has been widely used in the building industry for building energy benchmarking. However, this EUI-based building energy benchmarking could lead to a biased assessment because it overlooks other influential factors such as operational schedule, occupancy, plug-load, setpoint temperature, and weather (hereafter referred to as operational factors). To overcome the issue, the authors propose a normalization process for the building’s actual energy consumption considering the aforementioned factors. In this study, a concept of normalization coefficients was introduced based on the relationship between the operational factors and the change in energy consumption. The eXtreme Gradient Boost regression (XGBoost) models were used for deriving normalization coefficients that can convert the actual heating and cooling EUIs into the normalized EUIs per building under the operational factors. Validation studies demonstrated that the conversion of actual EUIs into normalized EUIs using these coefficients can contribute to fair building energy benchmarking. In other words, the proposed normalization approach holds promise for achieving more objective building energy performance benchmarking. Pages: 31 - 38 Paper:
