Energy efficiency research is usually focused on residential and office buildings, overlooking other typologies such as supermarkets, despite their high energy consumption. Knowing the typical consumption of the typology helps in decision making. However, during the simulation process, the need for calibration may present some difficulties, especially when it involves measurements in old buildings, with power control panels that are difficult to access or an electrical system that has already undergone several interferences and is not organized by end uses. Therefore, the objective of this study is to identify the potential of a simplified calibration method. This includes a preliminary study (with hourly measurements) of another building of the same type and size, analysis of electricity bills and data generated by computer simulation, using the EnergyPlus software. As results, the end uses of energy for the analyzed building were identified: refrigeration system (82%), equipment (11%), lighting system (6%) and HVAC (1%).
