Examination of vertical green facades and green roofs in terms of ecological criteria and evaluation of energy efficiency

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.
