Effects of Green Spaces on Microclimate in Sustainable Urban Planning

Abstract

In recent years, there has been a growing importance placed on the development of various models and scenarios aimed at mitigating the effects of climate change. This approach is gaining prominence in our country as well. This study is based on research conducted in the Yeşilyurt neighborhood within the Tarsus district of Mersin province. The primary objective of this research is to assess the impact of increased green space on microclimate conditions using ENVI-met simulation. Within the scope of this research, a comparison was made between the current situation and a scenario in which the amount of green space was increased. The analysis of green area quantities was conducted using the ENVI-met simulation software, utilizing climate data such as temperature, humidity, wind direction, and speed, which were obtained through measurements. In the scenario involving an increase in green space, the total green area was augmented from its current 2,487 m² to 4,398 m². The simulation results underscore the substantial effect of this augmentation on the microclimate. Average temperature values fluctuate between 31.11°C and 33.04°C, revealing that the expansion of green space leads to a reduction in temperature, thereby positively impacting the environment. This translates to an overall temperature decrease of approximately 0.45°C across the entire area. The research highlights the favorable influence of heightened green space on microclimate conditions, as evidenced by findings derived from ENVI-met simulations. It elucidates how such an increase can contribute to temperature regulation. These outcomes underscore the significance of deliberate green space incorporation in urban planning and design processes, guiding decisions that promote environmental sustainability. Thus, it is recommended that forthcoming strategies of local governments prioritize the expansion of green areas while considering factors related to microclimate and environmental quality.
