The Energy Performance of Shading Element and Double Skin Facade System Integration into Office Buildings in Turkey

Energy efficiency in building design tends to be important in reducing the share of construction sector in energy consumption and environmental problems caused by it. In this study, energy performance of an existing office structure was evaluated by integrating shading elements and double skin facade systems within the scope of energy efficiency in buildings. Initially, current energy performance of the building was examined by design builder program and then, the shading element alternatives and the double skin facade system alternatives were separately integrated into the structure and simulated by solar tool and design builder program. Alternatives with the highest energy performances were determined in both building components. Later in the study, the shading element and the double skin facade system alternatives, which gave the most successful results, were integrated into the building model simultaneously and the energy performance thus evaluated was compared with the energy performance of the existing building. According to results, the Shaded Double Skin Facade scenario indicated a drop in heating load of around 2% and a decrease in cooling load of about 45% compared to the present building model.
