Buildings account for a significant portion of global energy consumption. Both economic and environmental problems caused by energy consumption in buildings increase the importance of energy efficient design every day. The energy consumed in buildings is primarily used to provide user comfort by keeping the indoor-outdoor relationship in balance against the change in climate conditions. For this reason, the role of building facades which are the first point of contact with the external environment has an essential role in energy efficiency. As a solution with the developing technology, adaptive facades that can modify their functions according to certain parameters through materials, systems and components have been developed. This study aims to determine to what extent adaptive facades contribute to energy efficient design. In this regard, first of all, the importance of façades in terms of energy efficiency is emphasized and their relationship with other components of the building is examined. Then certain parameters are identified for energy efficient facade design, highlighting that adaptive facades are the most effective solution to meet these parameters. After defining adaptive facades and distinguishing them from traditional facades, their importance and features, they are divided into two categories as passive and active adaptive facades based on their responses to changing environmental conditions. Afterwards, six examples with adaptive facades are examined and evaluated based on their design approaches, compliance with the identified energy efficient facade design parameters, and the passive-active adaptive facade type they have. As a result, it is determined that adaptive facades contribute significantly to energy efficiency with their responses to energy efficient facade design parameters. In addition, adaptive facades, in which passive and active facade systems are used in an integrated manner, are proposed as the most ideal solution in terms of energy efficiency.

UYARLANABİLİR CEPHELER İLE ENERJİ ETKİN TASARIM

Binalar, küresel enerji tüketiminin büyük bir kısmını oluşturmaktadır. Binalarda enerji tüketiminin sebep olduğu hem ekonomik hem de çevresel sorunlar, enerji etkin tasarımın önemini her geçen gün artırmaktadır. Binalarda harcanan enerji genellikle değişen iklim koşullarına karşı iç-dış mekân ilişkisini dengede tutarak, kullanıcı konforunun sağlanması için harcanmaktadır. Bu nedenle enerji verimliliği konusunda dış ortamın yapı ile ilk temas ettiği yüzey olan cephelerin rolü büyüktür. Gelişen teknoloji ile birlikte çözüm olarak malzeme, sistem ve bileşenler aracılığı ile belli parametrelere göre işlevlerinde değişiklik yapabilen uyarlanabilir cepheler geliştirilmiştir. Bu çalışmada, uyarlanabilir cephelerin enerji etkin tasarıma ne ölçüde katkı sağladığının belirlenmesi amaçlanmaktadır. Bu doğrultuda, ilk olarak, cephenin enerji verimliliği konusundaki önemi belirtilerek, yapıyı oluşturan diğer bileşenlerle ilişkisi irdelenmiştir. Daha sonra, enerji etkin cephe tasarımı için belli parametreler belirlenmiş ve bu parametreleri karşılayabilecek en etkili çözümün uyarlanabilir cepheler olduğu vurgulanmıştır. Uyarlanabilir cephelerin tanımı, onları geleneksel cephelerden ayıran özellikleri ve önemi belirtildikten sonra, değişen çevresel koşullara verdiği tepkilere göre pasif ve aktif uyarlanabilir cephe olarak iki sınıfa ayrılmıştır. Ardından, uyarlanabilir cepheye sahip altı örnek tasarım yaklaşımları, belirlenen enerji etkin cephe tasarım parametrelerini karşılamaları ve sahip oldukları pasif-aktif uyarlanabilir cephe türüne göre incelenmiş ve değerlendirilmiştir. Çalışma sonucunda uyarlanabilir cephelerin enerji etkin cephe tasarım parametrelerine verdiği yanıtlar ile enerji verimliliğine önemli ölçüde katkı sağladığı tespit edilmiş, ayrıca pasif ve aktif cephe sistemlerinin birlikte entegre bir şekilde kullanıldığı uyarlanabilir cepheler, enerji etkinliği bakımından en ideal çözüm olarak önerilmiştir.
