Global warming and undeniable climatic change in the world have led to decreasing thermal comfort for humans. Urban heat island (UHI) is the most documented phenomenon which has led to the increasing temperature in urban areas. It has received much focus in the past few decades to evaluate the main effective criteria of UHI. Street heat has negative effects on human health and will only worsen in future; these negative effects would double in hot and dry urban area. This paper investigates the effects of UHI in these cities and illustrates the important factors which make them extremely hot. The outcome of this study can be used to determine the key guidelines for urban designers, urban planners, architects and landscape designers to recline the UHI impressions in urban areas and make more thermal comfort for Burgher.
One of the most important issues in various energy issues is to decrease fossil fuel energy usage and promote renewable energies in developing countries. Iran as a developing country began exploiting renewable resources from the early 1990s. This paper investigates the financial viability of renewable energy technologies in Kerman, which is located in the hot and dry parts of Iran and has a high potential of solar and wind energy. First the potential for solar and wind energy sources are studied and afterwards through two quantitative methods, the cost of this implementation is compared to the benefits gained. The results prove that without a massive financial support by the government, renewable energies would not be economically feasible to be implemented into private households.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
