Investigating the Effect of Facade Material on the Amount of Carbon Emission (a case study of a residential building in Tehran)

The issue of reducing carbon dioxide emissions is one of the most important issues of the day in Iran. Because if we ignore it, in addition to many problems, including environmental pollution, disease, and waste of resources and wealth, we may have to pay heavy fines to the international community in the near future. As a result, the importance of the emission of greenhouse gases, and the most important of them is carbon dioxide, and its dangerous consequences are clear. But the basic issue is the necessary tools and methods to reduce it. In this article, a residential building in Tehran has been studied with the aim of investigating the effect of using different building materials on the exterior walls of the building using Design Builder software. The residential building under study is a ۵-story building, and the area of each floor is ۱۰۰ square meters. The outputs of the software include embodied carbon, equivalent embodied carbon, and carbon emitted during the period of building operation. The results showed that the lowest amount of hidden carbon is related to the use of cement facades, and the highest amount is related to granite stone. By comparing the amount of carbon emissions during the exploitation period, it is clear that the lowest amount is related to the use of tufa stone and the highest amount is related to marble. Also, the best scenario is a cement facade and a facade with tufa stone.
