| Summary: | 碩士 === 國立政治大學 === 地政學系碩士在職專班 === 106 === Urban renewal is one of the most important ways to improve the urban environment. Therefore,this study conducted an analysis of environmental factors in residential cases before and after urban renewal and clarified the impact of urban renewal on the wind environment and the thermal environment of the ambient areas using computational fluid dynamics (CFD) simulation. The results of the study showed that the residential cases had a consistently significant impact on the wind environment, while the impact on the thermal environment varied from case to case. The main impacted area fell within a radius of 100~150 m. According to the results of the simulation, the shrink of buildings’ low floors, adjustments to building distance, and changes in paving will impacted the wind environment and the thermal environment following urban renewal.
In the future, we recommend that researchers include evaluations of the wind environment and thermal environment of urban renewal in the scope of simulation, shrink of buildings, building distance, and paving in order to clearly determine the mechanisms for environmental review for evaluators’ reference and ensure the reliability of the simulation.
