Energy crisis in the '70s, have induced awareness on rapidly consume of primary (non -renewable) energy sources and the negative impact of human on environment. Environmental consciousness and conservation of energy has become apparent as an increased awareness in the community. Natural ventilation is a significant factor to save energy by the methods implemented to the buildings according to different environmental factors. The main function of the buildings is fulfilling the requirements of users to live in a healthy artificial environment. Natural ventilation is significant in terms of global economy / energy conservation and users' health, is an important issue that should be taken into consideration in the design stage.
Common use of mechanical systems and insulated facades that technology and energy crisis couse, threat to users' health in time. The change of living conditions in consequence of developing technology affected the change of housing units and housing typologies. Many of the naturaly ventilated buildings which are encountered in literature review was found to be office buildings. It is possible to reduce dependence on mechanical systems and ensure user comfort with natural ventilation systems allowing user control in residential buildings, too. Therefore in this study, the necessity of natural ventilation in high rise residential buildigs increasing in today�s city and the natural ventilation solutions provided through facades were emphasized. Examples of naturally ventilated high rise residential buildings which have different climate, environmental and building features have been investigated. The inclusion of natural ventilation principles to the structures at the design stage, with an accurate analysis of the climate and environmental data, it is found possible to provide natural ventilation with less energy in many different situations.

Keywords: High rise building, multi storey residential buildings, natural ventilation, natural ventilation elements

70�li y�llarda ya�anan enerji krizleri, insano�lunun do�a �zerindeki birincil (yenilenemeyen) enerji kaynaklar�n� h�zla t�ketti�inin ve �evreye olan olumsuz etkisinin fark�na var�lmas�n� sa�lam��, �evre bilinci ve enerji korunumu toplumda artan bir bilin� olarak ortaya ��km��t�r. Do�al havaland�rma, farkl� �evresel etmenlere g�re yap�da uygulanacak y�ntemlerle, enerji tasarrufu sa�lanmas�nda �nemli bir etkendir. Yap�n�n temel i�levi; kullan�c�n�n sa�l�kl� bir yapma �evrede ya�ama gereksinimlerini kar��lamakt�r. K�resel ekonomi/enerji korunumu ve kullan�c� sa�l�� bak�m�ndan �nemli olan do�al havaland�rma, yap�n�n tasar�m a�amas�ndan ba�layarak g�z �n�nde bulundurulmas� gereken bir konudur.
Teknolojinin ve eneri krizlerinin beraberinde getirdi�i, mekanik sistemlerin yayg�n kullan�m� ve s�zd�rmaz yap� cepheleri, zamanla kullan�c� sa�l��n� tehdit eder hale gelmi�tir. Geli�en teknoloji ile beraber de�i�en ya�am ko�ullar� konut birimlerinin ve tipolojisinin de de�i�mesinde etkili olmu�tur. Literat�rde kar��la��lan do�al havaland�rmal� yap�lar�n �o�unun ofis yap�s� oldu�u g�r�lm��t�r. Konut yap�lar�nda da mekanik sistemlere ba��ml�l�� azaltmak ve kullan�c� kontrol�ne izin veren do�al havaland�rma sistemleriyle kullan�c� konforunu sa�lamak olanakl�d�r. Bu nedenle bu �al��mada g�n�m�zde kentlerde giderek �o�alan y�ksek katl� konut yap�lar�nda, do�al havaland�rman�n gereklili�i ve cepheler arac�l��yla sa�lanan do�al havaland�rma ��z�mleri �zerinde durulmaktad�r. Farkl� iklim, �evre ve yap� �zelliklerine sahip do�al havaland�rmal� y�ksek konut yap�s� �rnekleri incelenmi�tir. �klim ve �evre verileri do�ru analiz edilerek, do�al havaland�rma ilkelerinin tasar�m a�amas�nda yap�lara dahil edilmesiyle, bir�ok farkl� durumda az enerji ile do�al havaland�rma sa�laman�n olanakl� oldu�u g�r�lm��t�r.

Anahtar Kelimeler: Y�ksek yap�lar, �ok katl� konut yap�lar�, do�al havaland�rma, do�al havaland�rma elemanlar�
