Abstract

Background and Objective: The increase in heat waves in cities has caused many problems for Human health. Reducing environmental problems by reducing the ambient temperature and thus improving Human health is one of the most important concerns in the present age, which can be achieved by changing Urban forms and environmental elements. Method: The main method used in this research is numerical simulations, using Envi-Met and Leonardo software suites. Findings: The findings indicate that the higher the height-to-width ratio, the less access sunlight has to the environment, resulting in lower ambient temperatures. Shading due to the ratio (H / w), the presence of plants and wind in urban valleys can also reduce the ambient temperature. In addition, the reduction of impermeable surfaces of urban coatings and the presence of materials with high albedo, increase evapotranspiration, which provides cooling conditions for urban environments and reduces the adverse effects of urban heat on Human health. Conclusion: As a result, creating shadows through a combination of vegetation and diverse alterations in structures of H / W can be effective on reducing the ambient and surface temperatures. Moreover, the use of permeable surfaces and building materials with high albedo are effective in reflecting solar heat and can reduce the intensity of urban heat islands.
