A Proposed Method for Decisions on the Rehabilitation of Building Facades

The idea of the need to protect nature and natural resources is gaining importance every day. Sustainability refers to the protection of the environment for future generations. Architectural planning and design, as well as construction and demolition are now being evaluated with a long-term and multi-sided perspective. The use of existing building stock has great advantages in terms of resources and energy consumption in contrast to the damage to the environment inherent in the construction of a new building. The use of existing building stock allows for preservation of the environment and architectural identity, as well as economic benefit. Facade rehabilitation has become a key factor. Partial and extensive rehabilitation of building facades is directly proportional to the overall performance of the building. The decision to rehabilitate and the correct means of rehabilitation are critical to the building�s performance. This study is an examination of the process of making the decision to rehabilitate an existing building facade and the current methods of rehabilitation.

Do�an�n ve do�al kaynaklar�n gelecek nesiller i�in korunmas� gerekti�i bilincinin artt�� g�n�m�zde, s�rd�r�lebilirlik kavram�n�n �nemi de her ge�en g�n daha iyi anla��lmaktad�r. Buna paralel olarak, s�rd�r�lebilir mimari, planlama ve tasar�m a�amalar�ndan ba�lamak �zere, yap�m-�retim, uygulama, kullan�m ve y�k�m a�amalar�n�n tamam�n� kapsayacak �ekilde uzun vadeli ve �ok y�nl� olarak de�erlendirilmeye ba�lanm��t�r. Her bina yap�m s�recinde do�aya belli miktarda zarar vermektedir. Bu ba�lamda, mevcut binay� y�k�p yenisini yapmak yerine, binan�n performans�n� optimum d�zeyde tutacak �al��malar yapmak, hem �evresel ve ekonomik fayda sa�lamak hem de mimari kimli�i korumak a��s�ndan s�rd�r�lebilir bir yakla��m olarak nitelendirilebilir. Binan�n toplam performans�n�n art�r�lmas� veya mevcut performans�n korunmas�ndaki, anahtar fakt�rlerden biri cephelerin yenilenmesidir. Cephede yap�lacak k�smi veya kapsaml� yenilemeler, binan�n her t�rl� performans�na do�rudan yans�yacakt�r. Ancak, bina performans�n�n korunmas� ve art�r�lmas�n� sa�lamada yenileme eyleminin ger�ekle�tirilmesi kadar yenileme karar�n�n verilmesi ve do�ru yenileme stratejilerinin belirlenmesi de etkilidir. Bu �al��mada, mevcut bir bina cephesini yenilemeye karar verme s�recinde ve sonras�nda kullan�labilecek, cephenin mevcut durumunun de�erlendirilmesi ve bu de�erlendirme sonras�nda yenilenme gerekli g�r�len cephenin hangi s�re�te yenilenmesinin uygun olaca��n�n tespit edilmesine y�nelik bir y�ntem geli�tirilmi�tir.

Anahtar Kelimeler: Bak�m-onar�m, durum de�erlendirme; hasar; karar verme, s�rd�r�lebilirlik; yenileme.
