Feasibility of using green roof and shading device by adopting the total energy consumption approach: A case study in Tehran

Abstract

[EN] Greenhouse gases are responsible for climate change, and the building sector is one of the main areas to reduce carbon dioxide emissions. In terms of air pollution, Tehran is one of the top cities in the ranking (Heger and Sarraf 2018). Therefore, paying more attention to this issue is absolutely essential. GB (green building) is one of the parameters to achieve a sustainable city. This paper analyses GR (green roof) and SD (shading device), which are two crucial parts of a GB from the EC (energy consumption) approach in a residential building in Tehran city. The heating and cooling system in the building is based on natural gas and electricity. This paper compares energy consumption, including ELC (electricity consumption) and GC (gas consumption) before and after GR and SD to find out whether or not they are suitable for this building and the current case study.
