Forecasting electricity demand in buildings is now more accurate with Group Encoding (GE), a new method that uses only existing device operation data. Developed by researchers at the Institute of Science Tokyo, the method improved prediction accuracy by 74% in real-world tests.Forecasting electricity demand in buildings is now more accurate with Group Encoding (GE), a new method that uses only existing device operation data.
