**3. Input Variable Configuration**

In this study, we use hourly electric energy consumption data collected from 1 January 2015 to 31 December 2018 from an industrial building in Incheon, South Korea. Table 2 summarizes some statistics of the collected data. To construct our STLF model, we consider time factors, weather information, historical electric energy consumption, and electric rates for input variable configuration. The details are described in the following subsections.
