The Impact of Building Height on Microclimate Characteristic of Urban Open Spaces (Case Study: Narmak neighborhood). دانشگاه علم و صنعت ایران. 1402; 33 (4)
چکیده:
Urban planning and morphology are one of the most important factors affecting land surface temperature (LST) and microclimate chrematistics. The production of anthropogenic heat, mainly for cooling systems and lighting, has resulted in significant impacts on the quality of the thermal environment. These impacts include poor air quality, increased temperatures, higher energy consumption, and the development of urban heat islands (UHIs). With the growing urban population and increased building height, especially in metropolitan areas, there have been significant changes in the urban geometry, rate of pollution, amount of heat released, and meteorological parameters. All these factors contribute to the heat island phenomenon and significantly alter the microclimate in urban areas. The goal of this article is measuring the effects of height changes in buildings around Tehran metropolitan squares in a detailed plan on microclimatic changes. As part of a research study, the Hafthoz Square in Tehran was chosen as a case study. The researchers used a combination of simulation techniques (Envi-met) and GIS to detect the spatial variation of Land Surface Temperature (LST) and determine its quantitative relationship with building height and density. This was achieved through simulation modeling for the Narmak neighborhood of Tehran. As Conclusion, the results indicate that comparison on the simulation between the existing conditions and proposed scenario area showed that in the proposed scenario, wind speed and relative humidity decrease and ground surface temperature (UHI) and PPD and PMV indices increase. Therefore, if the detailed plan of Tehran metropolis is realized and implemented in many squares, it will be accompanied by changes in micro-climatic parameters in order to reduce the thermal comfort of citizens.
