Climate-based Performance Evaluation of Double Skin Facades by Building Energy Modelling in Central Europe

AbstractThermal, energy and comfort performance of double skin façades are evaluated compared to double and triple glazed, single skin façades for a highly glazed office in Central Europe. Simulations indicate that the buffer mode box type window performs better than the double glazed facade, however, the energy consumption and thermal performance of triple glazed façades are even better. The outdoor air curtain, ventilated box type window with shading shows cooling energy savings of 7% on average compared to the double glazed alternative and also performs better than the triple glazed façade, while maintaining the same thermal comfort
