A General Evaluation on Double Skin Facades

This study examines the literature of double-skin facade systems over the last decade, and, with the help of tables and graphics, investigates their advantages and disadvantages. Moreover, a detailed comparison is made between double skin fa�ade systems. The results of the study show that the greatest advantage (95%) of double skin facade systems is their provision of natural ventilation. Other advantages are highlighted according to their percentage as follows: An increase in interaction between user and environment because of the high proportion of transparency, support of heat and sound insulation, reduction in heat transmission and solar heat gain coefficient, an increase in thermal comfort, allowance of solar control elements between the two facade spaces, and protection of these elements from external environment conditions. The most commonly accepted disadvantage (72%) is overheating in the air space of the two facades. Other disadvantages are highlighted according to their percentage as follows: Problems related to a decrease in the amount of daylight entering the building, high investment costs, additional maintenance and repair costs, fire, and acoustic problems. In our country, architectural design decisions related to overheating must be taken so as to provide a positive contribution to energy performance and the applicability of these systems.

Bu �al��mada, literat�rde �ift cidarl� cephe sistemleri ile ilgili son on y�lda yap�lm�� olan �al��malar incelenmi� ve bu sistemlerin vurgulanan olumlu ve olumsuz y�nleri tablo ve grafikler yard�m�yla irdelenmi�tir. Ayr�ca �ift cidarl� cephe t�rleri aras�nda kar��la�t�rma yap�lm��t�r. Yap�lan �al��ma sonucunda, �ift cidarl� cephe sistemleri ile ilgili avantajlar�n en ba��nda %95 oranla bu sistemlerin do�al havaland�rmaya imkan sa�lamas� gelmektedir. Di�er vurgulanan avantajlar ise y�zdelere g�re s�ras�yla; �effafl�k oran�n�n y�ksek olmas� sayesinde kullan�c� ile �evre aras�ndaki etkile�imi artt�rmas�, �s� ve ses yal�t�m�n� desteklemesi, �s� iletimi ve g�ne� �s� kazan� katsay�s�n� d��rmesi, �s�l konforu artt�rmas� ve iki cephe aras�ndaki bo�lu�a g�ne� k�r�c� elemanlar�n yerle�imine olanak sa�lamas� ile bu elemanlar� d�� ortam�n olumsuz ko�ullar�ndan korumas�d�r. �te yandan hemfikir olunan dezavantajlar�n ba��nda % 72 oranla iki cephe aras�nda kalan hava bo�lu�undaki a��r� �s�nma problemi gelmektedir. Di�er vurgulanan �nemli dezavantajlar�n ise binaya giren g�n �� miktar�n�n azalmas� ile ilgili problemler, y�ksek yat�r�m maliyetleri, ek bak�m onar�m maliyetleri, yang�n ve akusti�e ili�kin problemler oldu�u tespit edilmi�tir. �lkemizde bu sistemlerin uygulanabilirli�i ve enerji performans�na olumlu katk� sa�layabilmesi i�in a��r� �s�nma problemini g�z �n�nde bulunduran mimari tasar�m kararlar�n�n al�nmas� gerekmektedir.
