As urban density increases, sustainable building design is required to reduce energy consumption and mitigate climate impacts. Urbanization has led to the development of densely built-up areas characterized by close spacing of buildings and structures, resulting in a significant reduction in air velocity. Building facade design is essential to sustainable building design as it can significantly influence the microclimate around a building. This research proposes a new method of ceramic facade design, which realizes the passive ventilation based on the building facade. The proposed method involves wind field vectors generated by computational fluid dynamics software and using them as influencing factors for multi-proxy field generation of building facades. The system helps alleviate the problem of weakened airflow in the city. In addition to the energy-saving benefits, the proposed method offers opportunities for sustainable building development. By combining sustainable design principles with aesthetic design, the proposed method provides a promising solution for improving urban streets' comfort and energy saving in a humid subtropical climate.
In the last two decades, designers in the computational design world have increasingly employed agent based models (ABMs) in architectural design and construction. The researchers introduce this concept to delve into more intricate and adaptable art forms and shapes, evolving into the refined term ‘multi-agent systems’. Drawing inspiration from Craig Reynolds Boids algorithm, the authors developed a multi agent design method. This method encodes a series of agents with tasks to design a porous facade screen for manipulating airflow. Our established principles indicate that the wind vector derived from CFD analysis plays a crucial role as a controlling factor in generating the agent field path.
