Title:
Improving Urban Microclimate in Real-World Practice in High Density Cities: Performance Simulation and Genetic Algorithm

Abstract

Stagnant airflow and urban heat island effects threaten human comfort and health in high density cities such as Hong Kong. There is a practical need to reduce heat stress and air pollution in the public realm during urban development supported by simulation tools. Existing performance simulation methods tend to be overly complex and computationally demanding, limiting their usefulness for the design team at early stage; The design process, detached from the timely feedback of performance simulation, often rely on the practitioners’ intuition or personal experiences, which may not always yield the best solution for the particular site. To address the above gap, a novel simulation-design workflow is developed in this study in order to advance sustainable urban design in Hong Kong. Rapid performance simulation tools have been linked with Genetic Algorithms in order to iteratively optimize the urban design schemes based on selected performance criteria. A human-computer workflow has also been applied in parallel in order to ensure compliance with practical constraints such as zoning, building code, and development priorities. The workflow has been preliminarily tested in a real-world urban redevelopment project in Hong Kong with marked improvement in environment performances. The outcomes of this study will contribute to research literature in performance simulation and optimization technologies; it is also expected to provide new tools to enhance sustainable urban design practice in Hong Kong.
