Abstract
Various parameters can be integrated in material-based computational design in architecture. Materials are the main driver of these processes and evaluated with the constraints related to the form, performance, and fabrication techniques. However, current methodologies mostly involve investigating already existing materials. Studies on computational material design, in which new materials are developed by designing their microstructures in response to the performative issues, are generally undertaken at the material scale, and not adopted to the architectural design process yet. To resolve this issue, the methodology titled Interscalable Material Microstructure Organization in Performance-based Computational Design (I2MO_PCD) is developed and presented in three stages, including (1) identification of different types of material microstructures, (2) computational material design, and (3) prototyping. Data-based material modelling and visualization, and algorithmic modelling techniques are utilized, followed by various performance simulations as a part of an iterative process. New microstructure organizations are designed computationally, organized under three main groups as linear-curvilinear, crystal and metaball-voronoi. The outcomes of different performance analyses, including structure, radiation, direct sun hours, acoustics and thermal bridge were compared. Thus, the role of geometrical organization of microstructures, scales and material types in different performance computations were identified, by designing and fabricating synthetic materials.
在建筑领域基于材料的运算化设计中,可以整合各种参数。材料是这些过程的主要驱动力,并结合与形式、性能及制造技术相关的限制条件进行评估。然而,当前的方法大多涉及对现有材料的研究。关于运算化材料设计的研究,即通过设计微观结构来开发新材料以应对性能问题,通常是在材料尺度上开展的,尚未应用于建筑设计过程。为解决这一问题,本文开发了一种名为 “基于性能的运算化设计中跨尺度材料微观结构组织”(I2MO_PCD)的方法,并分三个阶段进行阐述,包括:(1)识别不同类型的材料微观结构;(2)运算化材料设计;(3)原型制作。该方法运用了基于数据的材料建模与可视化,以及算法建模技术,随后进行各种性能模拟,并将其作为迭代过程的一部分。通过运算化设计出新的微观结构组织,这些组织主要分为线性 - 曲线型、晶体型和元球 - 沃罗诺伊型三大类。对不同性能分析的结果进行了比较,包括结构、辐射、日照时长、声学和热桥等方面。因此,通过设计和制造合成材料,确定了微观结构的几何组织、尺度以及材料类型在不同性能运算中的作用。
