Biomimetic approach for energy-efficient building envelope design in Doha

Öz

In this study, an approach is proposed for building envelope designs that directly affect the energy consumption of buildings in response to the ever-increasing energy demand of the built environment due to the increasing population around the world. Within the scope of the study, it is aimed to improve the energy efficiency of the building envelope system created with a nature-inspired approach, by considering both the design and simulation processes together. The entire architectural integration process of this envelope system, developed for the office unit located on the south facade of a fictitious office building in Doha, Qatar, with extreme weather conditions, is discussed. The effects of the developed biomimetic envelope design on cooling load and daylight parameters are analyzed along with the simulation outputs generated throughout the study. As a result of the study, it was observed that the building envelope system created with the biomimetic approach improved the building in terms of energy efficiency

Doha’da enerji verimli bina kabuğu tasarımı için biyomimetik yaklaşım

Öz

Bu çalışmada dünya genelinde artan nüfusa bağlı olarak yapılı çevrenin her geçen gün artan enerji talebine karşılık binaların enerji tüketimini doğrudan etkileyen bina kabuk tasarımları için bir yaklaşım önerilmektedir. Çalışma kapsamında doğadan ilham alan yaklaşımla oluşturulan bina kabuk sisteminin hem tasarım hem de simülasyon süreçleri birlikte ele alınarak enerji verimliliği noktasında iyileştirme hedeflenmektedir. Ekstrem hava koşullarına sahip Doha, Katar'da hayali bir ofis binasının güney cephesinde yer alan ofis birimi için geliştirilen bu kabuk sisteminin tüm mimari entegrasyon süreci ele alınmaktadır. Çalışma boyunca oluşturulan simülasyon çıktıları ile birlikte geliştirilen biyomimetik kabuk tasarımının soğutma yükü ve gün ışığı parametreleri üzerine etkileri analiz edilmektedir. Çalışma sonucunda biyomimetik yaklaşımla oluşturulan bina kabuk sisteminin binayı enerji verimliliği açısından iyileştirdiği gözlemlenmiştir.
