性能导向的数字幕墙可行性分析验证——以南京大学苏州校区(西区)文体中心幕墙设计为例

Feasibility Analysis and Verification of Performance-oriented Digital Facade--Taking the façade design of the Cultural and Sports Centre of Nanjing University Suzhou Campus(West)as example

南京大学苏州校区文体中心是校区西片区重要的文化展示载体,也是该片区的视觉中心和形象主体之一。作为西片区承上启下的纽带,文体中心要将百年老校的历史积淀和新校区的科技创新融入其中,其中幕墙作为“桥梁”链接起了建筑文脉和城市界面。本文以定性定量的方式,通过图形学算法研究造型和材料,基于方案计算建筑内部通风、眩光、照度多种性能数据,达到了幕墙构架美观和性能的最佳取舍。该方案旨在高效获得优异的建筑内部和外部性能,并形成算法平台以适应不同建筑中非标准构件正向设计的使用需求。

The Culture and Sports Centre of Suzhou Campus of Nanjing University is not only an important cultural display carrier in the west area of the campus,but also one of the visual center and image subjects of the area.As the historical link of the west area,the Culture and Sports Centre should integrate the historical precipitation of the century-old school with the scientific and technological innovation of the new campus,in which the façade acts as a“bridge”linking up the architectural context and the urban interface.In this paper,both qualitative and quantitative approach is used to study the shapes and materials through graphical algorithms,and based on the scheme,various performance data on ventilation,glare,and illuminance are calculated to achieve the optimal trade-off between aesthetic and performance of the façade structure.The scheme aims to efficiently obtain excellent interior and exterior performance of buildings and forms an algorithmic platform to accommodate the use requirements of non-standard component forward design in different buildings.
