Abstract
In this study, a set of generation, simulation and optimization methods are introduced to automatically build urban block models that have better environmental performance. With the automatic generation tool called Penguin developed in Grasshopper, urban designers can translate a set of indexes including floor area ratio, building density and height limit into 3D models and visualize land-use distribution. 3rd-party simulation and optimization tools in Grasshopper such as Ladybug, Butterfly and Octopus are connected to Penguin to build an automatic performance-based optimization workflow. A real project in Shanghai, China is illustrated to depict the whole workflow with outdoor airflow simulation and solar radiation evaluation. After 12 h of evolutionary calculation, the best building layout and indexes distribution are found about 35% superior to the worst one.
