Abstract: In the last years, the global shopping center (SC) inventory increased significantly. Additionally, the energy demand of SC is in general high compared to other commercial buildings. Thus, research in the field of energy efficient SC is becoming increasingly important. In this paper, an approach for modeling the building energy system (BES) of SC in Modelica is presented. The energy saving potential in the overall system of a recently proposed ventilation concept for SC is investigated (Mathis et al., 2015). Therefore, following the presented approach, three different supply system variants are modeled. The simulation results show that the annual primary energy demand for air conditioning can potentially be reduced by up to 35.1 %.
