Sustainability is the sum of the precautions and conditions necessary to sustain life on earth. The major elements of sustainable design are choice of material and the building�s post-construction performance. The most important factor in terms of building management is energy usage. On building envelope sections which are created to provide energy savings, the value of evaluating water vapor movement is often overlooked. Levels of condensation should not exceed the limits specified in the regulations. This is because the condensed water must not harm the building material or dry it out during the evaporation period. However, the thermal resistance of the building material is affected during the process before the drying period. Deterioration of the insulation material over time means that many theoretical level calculations do not reflect the true situation. In addition, due to the fact that the standards of some of these calculations are done in steady state conditions, realistic results cannot be achieved. If special precautions are not taken with regards to this, condensation damage occurs on the building elements. In this study of the climate conditions in Edirne, calculations are made using the computer program WUFI�2D-3 for buildings� most frequently condensed reinforced concrete wall elements. Insulated and uninsulated wall sections are modeled for periodically changing external and constant internal environmental conditions. For comparison purposes, the reinforced concrete walls are calculated, first for non-insulation, and then insulated with different position of isolation. The calculated results obtained from the WUFI�2D-3 program are shown in graphic form.

Keywords: Humidity trasfer; efficient use of energy; heat transfer; building envelope; condensation.

S�rd�r�lebilirlik, d�nya �zerindeki ya�am�n devaml�l��n�n sa�lanabilmesi i�in gerekli ko�ullar ve �nlemler b�t�n�d�r. S�rd�r�lebilir tasar�m�n as�l bile�enleri malzeme se�imi ve binan�n in�a edildikten sonraki performans�d�r. Binan�n i�letme performans�nda da en b�y�k etken enerji kullan�m�d�r. Enerjinin verimli kullan�m� ancak yap� kabu�unun do�ru se�imi ile m�mk�n olacakt�r. Enerji tasarrufu sa�lamak amac�yla olu�turulan yap� kabu�u kesitlerinde, su buhar� hareketi a��s�ndan de�erlendirme g�z ard� edilmektedir. Yo�u�an suyun yap� malzemesine zarar vermemesi i�in yo�u�ma suyu miktar�n�n s�n�r� a�mamas� veya buharla�ma periyodunda bulundu�u b�lgeden ��kmas� gerekmektedir. Fakat buharla�ma (kuruma) periyoduna kadar ge�en s�re�te yap� malzemesinin �s�l direnci etkilenmektedir. Teorik d�zeyde yap�lan hesaplamalar�n bir�o�u yal�t�m malzemesinin zamanla bozulmas� nedeniyle ger�ek durumu g�stermemektedir. Ayr�ca standartlar�n bir k�sm�nda bu hesaplamalar sabit rejimde yap�ld��ndan, ger�ek�i sonu�lara ula��lamamaktad�r. Bu konuda al�nmas� gereken �zel �nlemler al�nmad��nda, yap� elemanlar�nda yo�u�ma zararlar� ortaya ��kmaktad�r. Bu �al��mada Edirne iklim ko�ullar�nda, binalarda yo�u�ma problemlerinin en �ok rastland�� betonarme duvar elemanlar� i�in, d�� ortam �artlar�n�n periyodik olarak de�i�ti�i, i� ortam�n sabit kabul edildi�i yal�t�ml� ve yal�t�ms�z duvar kesitleri model al�narak, WUFI�2D-3 bilgisayar program� ile hesaplamalar yap�lm��t�r. Kar��la�t�rma a��s�ndan betonarme duvar, �nce yal�t�ms�z daha sonra da yal�t�m�n duvar�n farkl� yerlerine uyguland�� durumlar i�in hesaplanm��t�r. WUFI�2D-3 program� ile elde edilen hesap sonu�lar� grafikler halinde sunularak de�erlendirilmi�tir.

Anahtar Kelimeler: Buhar kontrol�; etkin enerji kullan�m�; �s� iletimi; yap� kabu�u; yo�u�ma.
