【摘要】：表皮作为建筑给人的第一感知要素,一直以来是建筑师们重点关注的一个部分。近年来,随着参数化建筑设计及相关理论的发展,使得建筑的表皮形式设计打破了传统的设计方法,呈现出越来越丰富的形式,同时也在生态建筑的设计方向上提供了全新的思路和广阔的发展前景。将参数化设计方法和建筑物理环境模拟相结合,通过计算机编程和数据处理,形成的一套表皮形式的生成方法,能够快速生成多种建筑表皮形式,因而能够为建筑师提供大量的选择方案。建筑表皮的细分方式有多种,其中运用几何学作为建筑表皮的细分机制,对于建筑表皮的形式设计起到了非常重要的影响,成为一种重要的表皮设计方法。简单的几何学模式通过现代计算机进行数字转换后,应用于建筑表皮能够产生非常好的艺术效果。本设计中主要涉及到的几何学包括分形几何学、平面镶嵌及其相关理论。本文以基于分形算法的准周期性平面镶嵌作为表皮细分机制,探索从几何形式算法出发、整合了参数化建筑设计和物理模拟分析的建筑表皮形式设计方法。最终成果为基于三种镶嵌原型的系列表皮形式的生成方法,以及其在不同建筑形体上的运用。本设计主要分为以下四个过程：首先是表面网格的生成过程,其中包括两个方面：一是镶嵌原型对表面的划分,主要涉及到的软件为grasshopper中的PanelingTools表面镶嵌插件；二是通过在grasshopper环境下的VB Script进行编程,按照相应的几何规则实现对镶嵌原型进行分解操作,从而形成初始网格。其次是物理模拟阶段,通过物理模拟软件Ecotect及其与grasshopper的接口插件Geco将前面生成的初始网格作为计算网格导入进行日照分析,得出建筑表面每个网格单元的热辐射值。接下来是进行参数控制来实现网格合并的过程,利用日照计算的数据结果来对网格按照几何规则进行合并处理,形成一定的层级关系,以及通过临界值的设定来形成对不同表皮材质的选择。最后是对表皮进行功能适应性处理,通过与由开间和层高形成的规则网格进行叠加,控制一定的开窗率,从功能性的角度来赋予表皮以实际的意义。
[Abstract]:As the first perceptual element of architecture, epidermis has always been an important part of architects' attention. In recent years, with the development of parameterized architectural design and related theories, the design of building epidermis has broken the traditional design method and presented more and more rich forms. At the same time, it also provides new ideas and broad development prospects in the design direction of ecological buildings. By combining parameterized design method with building physical environment simulation and computer programming and data processing, a set of epidermis forms can be generated quickly. As a result, there are plenty of options available to architects. There are a variety of subdivision methods of architectural epidermis, in which geometry is used as the subdivision mechanism of architectural epidermis, which plays a very important role in the formal design of architectural epidermis and becomes an important method of skin design. The simple geometry model can be used in building skin to produce very good artistic effect after digital conversion by modern computer. The geometry involved in this design includes fractal geometry, plane mosaic and related theories. In this paper, the quasi-periodic plane mosaic based on fractal algorithm is used as the epidermis subdivision mechanism. Based on the geometric form algorithm, the parametric architectural design and physical simulation analysis are integrated into the architectural epidermis design method. The final result is the generation method of series epidermis based on three mosaic prototypes and its application in different architectural forms. This design is mainly divided into the following four processes: first, the process of surface mesh generation, including two aspects: first, the mosaic prototype of the surface of the partition, the main software involved in the grasshopper panel tools surface mosaic plug-in; The second is to decompose the mosaic prototype according to the corresponding geometric rules by programming in VB script in grasshopper environment, thus forming the initial mesh. Secondly, in the physical simulation stage, through the physical simulation software Ecotect and its interface plug-in with grasshopper, Geco, the initial grid generated by the former is imported into the computing grid for sunshine analysis, and the thermal radiation value of each grid element on the building surface is obtained. Then the process of grid merging is realized by parameter control. The grid is merged according to geometric rules by using the results of sunshine data to form a certain hierarchical relationship. And through the setting of critical value to form different epidermis material selection. Finally, the functional adaptive treatment of the epidermis is carried out. By superposing with the regular mesh formed by the open space and the height of the layer, the window opening rate is controlled, and the epidermis is endowed with practical significance from a functional point of view.
