Abstract

In this study, it is aimed to determine the results of the usage of vertical green façade and green roof systems which are increasing in use today, in four different climatic zones of our country, considering the annual heating, cooling and total energy consumption. Based on a building model in the study, the effect of the green facade and green roof applications on the buildings' annual heating and cooling loads was tried to be determined for four cities of our country with four different climatic characteristics. In selected cities in these climate regions, a traditional building and buildings with vertical green facades and green roof applications were compared. Situated in Turkey's four different climatic zones with the results achieved in this study was found to be differences in four different city's annual energy consumption. In the annual total energy consumption; Antalya city with 2.68% as a result of application of only planted roof systems, Konya city with 11.64% as the result of application of only vertical green façade systems, and highest benefit rates in Erzurum city with application of both systems and 14.38% at the end. As a result of this, considering the annual total energy consumption, green facades and green roof applications in buildings are found to have a positive effect on the energy performance of the building, even though it does not vary from region to region.

Düşey yeşil cepheler ve yeşil çatıların ekolojik kriterler bakımından incelenmesi ve enerji verimliliğinin değerlendirilmesi

Abstract

Bu çalışmada, günümüzde kullanımı artan düşey yeşil cephe ve yeşil çatı sistemlerinin ülkemiz sınırlarında dört farklı iklim bölgesindeki kullanımının yıllık ısıtma, soğutma ve toplam enerji tüketimleri dikkate alındığında ne gibi sonuçlar vereceğinin tespit edilmesi amaçlanmıştır. Çalışmada, bir bina modeli esas alınarak düşey yeşil cephe ve yeşil çatı uygulamalarının, binaların yıllık ısıtma ve soğutma yüklerine etkisi, ülkemizin dört farklı iklim özelliğine sahip dört kenti için belirlenmeye çalışılmıştır. Bu iklim bölgelerinde seçilen kentlerde, geleneksel bir bina ile düşey yeşil cephe ve yeşil çatı uygulamalarının kullanıldığı binalar karşılaştırılmıştır. Ulaşılan sonuçlar ile Türkiye’nin dört farklı iklim bölgesinde yer alan dört farklı kentin yıllık tüketim enerjilerinde farklılıklar olduğu saptanmıştır. Yıllık toplam enerji tüketiminde; sadece bitkilendirilmiş çatı sistemlerinin uygulanması sonucunda %2.68 ile Antalya kenti, sadece düşey yeşil cephe sistemlerinin uygulanması sonucunda %11.64 ile Konya kenti, her iki sistemin uygulanması soncunda ise %14.38 ile Erzurum kentinde en yüksek fayda oranları sağlanmıştır. Bunun sonucunda, yıllık toplam enerji tüketimleri dikkate alındığında, binalarda yeşil cephe ve yeşil çatı uygulamalarının, bölgeden bölgeye farklılık göstermesine rağmen binanın enerji performansını olumlu yönde etkilediği saptanmıştır.
