In conclusion, it is aimed to create a resource that will help to develop suggestions for design solutions that can be implemented on the facades Secondly, three buildings that make a difference with their facades and their integrated shading systems are examined in detail. In the direction of these information, first of all, new concepts in building envelopes are investigated, adaptive facade systems are defined and classified in this study. With the opportunities provided by technological improvements, these systems that adapt according to the position of the sun bring innovative approaches in architecture and the shell transforms a dynamic sculpture with the shape changing form. Adaptive facades increase building energy performance significantly in the context of their ability to utilize high thermal performances, natural ventilation and daylight, and optimize solar gains. These types of facade systems, due to their ability to adapt to changing conditions, can reduce energy consumption while enhancing indoor comfort. While the kinetic structure exposed to solar energy responds by moving to changing solar conditions, it is actively engaged in influencing the transition between the inside and the outside. The traditional static building envelope, under the influence of changing climatic conditions, has become a kinetic element. People want and need to be in structures that are under their control and can adapt to the variability of environmental factors. Adaptive facades which has the ability to respond dynamically to environmental conditions are an important breakthrough in shaping the future facades. In addition to the different design approaches in architecture, the developments in the facade systems are examined from the perspective of “Adaptive building facades”, one of the most remarkable of these, in terms of shading elements. As identity cards of buildings, facades tend to draw attention with their designs today. It is an important building component in terms of both design context and ability to meet performance needs. Façade is a transitional element between interior and exterior environment. There are important duties to building facades in terms of energy conservation and their importance is increasing every day.
Also when the windows on each side of building are open air can flow from east to west without being obstructed by the walls, as ventilation panels allow for cross ventilation.Today, due to rapidly depleting energy sources, the importance of energy conservation is emphasized more than ever in the world.
The same happens when the air inside is cooler except the air inside is replaces with cool air. The stack effect means that when the air outside is warmer then the air inside the warmer air will float out the top of the solar flue being replaced by cooler air at the bottom. There is also natural ventilation throughout the building as air can freely flow through the solar flue which displays the stack effect.
The east façade of the building consists of two layers, creating a buffer, and is ventilated on each floor. The colored panels on this side of the building can be opened and closed by the occupants in order to let in or shut out light however, they can also be controlled by management in order to prevent overheating. The west façade of the building consists of three layers that create the solar flue. The solar shading system and the solar flue were designed with the use of the computational fluid dynamic (CFD) analyses which allowed for the room temperatures throughout the year to be observed. The GSW Headquarters in Berlin by Sauerbruch Hutton is designed with a low energy concept and uses systems of ventilation, heating, and lighting in order to reduce the energy consumption.
