Researchers in Mashhad, Iran, are investigating how green roofs can enhance the quality of life in cities with arid climates

Abstract

Mashhad, the second-most populous city in Iran, is situated in a hot and dry climate, and climate change has led to the temperature in this city climbing in recent years. This study's objective is to design a green roof per the region's hot and arid climate to maximize plant growth. The thermal comfort of citizens is explored in this study. A questionnaire was developed and distributed to 406 individuals for this experiment. The frequency measurement test was utilized to do statistical computations in order to quantify the sample's frequency, while the chi-square test (chi-square) was utilized to assess the relationship between class and rank variables. Residents from thirteen distinct neighborhoods are selected at random and proportionally. The findings of this study indicate that the positive effects of green roofs extend beyond the city of Mashhad and have a global impact. When green roof development is performed on a large scale in a city or region, many of the negative consequences of environmental change over the past several decades will be offset. By putting green roofs on buildings and all over cities, the effects of climate change are being fought off better. However, a scientific and preferred approach for installing and cultivating green roofs in Mashhad is of greater importance. Using the data analysis of the questionnaire, the desires, interests, and concerns of Mashhad's population were identified. The following development plan shows how the green roof field can grow desirably and acceptably.
