Over the last decades, computational methods have provided significant potential for integrated fa�ade systems with energy efficiency, the generation of numerous alternatives, the optimisation of complex requirements, and the inspiration of creativity in architecture. In this sense, the study addresses two primary issues. First, conventional methods are inadequate in a holistic perspective of the multiple objectives of fa�ade systems. Second, poorly designed or transformed media fa�ades are a common problem in many developing countries. This study developed a design strategy for an Integrated Fa�ade System (IFS) that consists of (i) simulation, (ii) analysis, and (iii) optimisation stages in a feedback loop. This design strategy was implemented to integrate the fa�ade in terms of multiple data based on functions. The methodology is organised into two main sections based on the urban scale fieldwork and test of the suggested strategy through the case study. The fieldwork has been done to determine the case study building in Istanbul. Two additional fa�ade functions, media display, and solar shading are chosen here to investigate the constraints, correlations, and consistency of multifunctional integration in a fa�ade system. The finding showed that the developed IFS can contribute to the use of factual data as a design input. Another result showed that this IFS decreased solar radiation by 51% during the summer period. This algorithmic system has flexibility and affordance that refers to enhancing building performance within different contexts.

Keywords: Computational design, integrated fa�ade system, media fa�ade; parametric design strategy

21. y�zy�lda hesaplamal� yakla��mlar, enerji verimlili�i, �ok say�da alternatifin �retilmesi, karma��k gereksinimlerin optimizasyonu ve mimaride yarat�c�l��n ilham� i�in �nemli bir potansiyel sa�lamaktad�r. �al��mada bu ba�lamda ele al�nan iki ana problem bulunmaktad�r. �lk olarak, geleneksel y�ntemler, cephe sistemlerinin �oklu ve karma��k hedeflere b�t�nc�l yakla��m sa�lamakta yetersiz kalmaktad�r. VZ �kincisi, k�t� tasarlanm�� veya d�n��t�r�lm�� medya cepheleri, bir�ok geli�mekte olan �lkede yayg�n bir sorundur. Bu �al��ma, bir geri bildirim d�ng�s�nde (i) sim�lasyon, (ii) analiz ve (iii) optimizasyon a�amalar�ndan olu�an Entegre Cephe Sistemi (ECS) i�in bir tasar�m stratejisi geli�tirmektedir. Bu tasar�m stratejisi, fonksiyonlara dayal� �oklu veri tabanl� cephe entegrasyonu i�in uyguland�.
Metodoloji, kentsel �l�ekli saha �al��mas�na ve �nerilen stratejinin vaka �al��mas� yoluyla test edilmesine dayal� olarak iki ana b�l�m halinde d�zenlenmi�tir. �stanbul�da bulunan vaka binas�n�n belirlenmesi i�in saha �al��mas� yap�lm��t�r. Cephe sisteminde �ok i�levli entegrasyonun k�s�tlamalar�n�, korelasyonlar�n� ve tutarl�l��n� ara�t�rmak i�in �al��mada iki ek cephe i�levi, medya g�sterimi ve g�ne� k�r�c�s�, se�ilmi�tir. Bulgular, geli�tirilen ECS'nin, olgusal verilerin tasar�m girdisi olarak kullan�m�na katk�da bulunabilece�ini g�stermektedir. Di�er bir sonu�, bu ECS'nin yaz d�neminde g�ne� ��n�m�n� %51 oran�nda azaltt��n� ortaya koymakatd�r. Bu algoritmik sistem, farkl� ba�lamlarda bina performans�n� art�rmaya olanak sa�layan esnekli�e ve uygunlu�a sahiptir.
