Simulation Aided Design Using “CFD simulation – design loop” for a Better Thermal Environment
At present, early research has been conducted in the fields of the urban heat island effect and urban microclimate on data collection and valuation, making recommendations for policymaking and urban planning in tropical cities, e.g. Singapore. However, it is still rather difficult for urban designers to apply the findings without useful tools and actionable knowledge, even though the basis for such has been produced by urban climate scientists. On this basis, this study focuses on tropical outdoor space from the interdisciplinary perspective of urban design and urban climate to explore the practical method of CFD simulation – design loop for allowing urban designer access to the urban microclimate and thus applying the knowledge to create public space for citizens that has enhanced thermal comfort as well as being aesthetically pleasing. Firstly, the two dimensions of thermal comfort – social cultural and technological – are clarified. The study then summarizes the problem of current urban climate research that relies on lowresolution and abstract models, and the development of CFD simulation as an applicable solution. The CFD simulation – design loop is thus proposed as a useful method for research and practice by urban designers. Finally, this study suggests future systematic research on measurable elements of public space to take this important area forward.
