Abstract: In this study, a multizone model of an existing shopping mall is developed in IDA Indoor Climate and Energy (IDA ICE). The model is validated using field measurements regarding use of energy for heating, sum of cooling and ventilation, operational electricity and tenant electricity. In addition, other input data used are energy use, operation hours, customer frequency, lighting, building envelope, HVAC system and control strategies. In this study, a parameter analysis regarding the building orientation, glazed façade area ratio and lighting is conducted. Results show that the shops’ lighting powers dominate the cooling demand and imply that current internal loads decreases the sensitivity regarding energy demand of moderate changes in the glazed façades and building orientation.
