双曲面表皮作为当今越来越多应用的表皮形式,创造了与传统建筑造型具有显著差异性的建筑形象,与此同时也带来了诸多如经济性、表皮网格拟合精度差及光热性能适应等方面的问题.研究从西安腾讯双创小镇的表皮设计入手,在方案创作中融入“新丝绸”和“无穷”的概念,同时基于参数化设计平台Rhino&Grasshopper进行双曲面表皮的设计优化.研究梳理了双曲面表皮实践的优化设计流程,从曲率控制下的曲面形态优化、曲面网格划分及单元优化以及光热性能导向的表皮洞口优化等角度进行深入探究,验证了该流程的适应性和双层表皮系统性能的优越性,构建具有生态特征并符合美观需求的双曲面表皮.

Hyperboloid skin, as a more and more applied skin form, has created a unique architectural image which is significantly different from the traditional architectural modeling, but at the same time has brought a lot of problems such as economy, poor fitting accuracy of skin mesh and adaptation of light and heat performance. Starting from the skin design of Tencent “double-innovation” town in Xi'an, this research incorporated the concepts of “new silk” and “infinity” into the project creation, and optimized the design of hyperboloid skin based on the parametric design platform Rhino & Grasshopper. The research sorts out the practice of the hyperboloid skin, and made an in-depth exploration from the perspectives of surface shape optimization under curvature control, surface meshing and element optimization, and photothermal performance-oriented skin opening optimization, which verified the adaptability of the process and the performance of the double skin system, and constructs a hyperboloid skin with ecological characteristics and aesthetic requirements.
