Appreciation towards SOM for providing the following description:
保利国际广场位于故宫和首都机场之间，在临近首都机场高速的新建商务区里占据着优越的位置。项目场地由主楼和两栋规模小些的配楼组成。三栋大厦的椭圆形基底轮廓跳脱了毗邻的城市肌理的刚性几何形状，让周围的公园景观与项目场地水乳交融。园林绿化覆盖了车库坡道和疏散楼梯，最大限度地减少了它们的视觉影响，同时还构建出宁静、随地形起伏的步行道。
Located midway between the Forbidden City and Beijing Capital Airport, Poly International Plaza occupies a prominent position in a new business district adjacent to the Capital Airport Expressway. The project site comprises a main tower and two smaller supporting towers. The elliptical footprint of the three towers frees the buildings from the rigid geometry of the adjoining urban fabric, allowing the landscape of surrounding parks to continue seamlessly through the project site. The landscaping covers garage ramps and egress stairs, minimizing their visual impact while creating a tranquil, undulating topography with pedestrian paths.
▼建筑外貌，surface
主楼的外观设计受中国纸灯笼启发，在构成图案的连续斜肋框架上安装宝石切割面造型的玻璃幕墙，让立面上天空浮映，日辉闪烁。外框架结构体系形成外层保温墙体，内层玻璃墙体之内才是办公空间。这一设计提供了自然光照的公共区域，可用于会议和社交互动，同时也构成楼层之间的空间和视觉联系。大跨度的结构设计，不仅提供广阔的内部空间，可营造无柱工作环境，而且还采用了具有高度可持续性的建筑/暖通方法来应对北京特有的气候和空气质量的挑战。
Inspired by Chinese paper lanterns, the design of the main tower’s exterior is formed by a continuous diagrid pattern, with a jewel-like faceting that shimmers as it reflects the sky. The exoskeleton structural system forms an outer thermal envelope around the office spaces, which are enclosed within a second glazed interior envelope. This creates daylit communal areas that accommodate meetings and foster social interaction, while establishing physical and visual connections between floors. The long-span structural design not only opens up the interior, creating a column-free work environment, but also employs a highly sustainable architectural/mechanical approach to address the climatic and air quality challenges particular to Beijing.
