Simulation aided Design : Using “CFD simulation – design loop” for Better Thermal Environment

Abstract

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.
