保利国际广场中国北京Poly International Plaza Beijing, China 业主：保利（北京）房地产开发有限公司规模：116,000平方米高度：161.2米摄影：Bruce DamonteSOM 服务范围: 建筑设计、结构工程竣工年份: 2017年保利国际广场位于北京故宫和首都机场之间。
业主中国保利集团的愿景是将项目建设为北京新兴的国际商业中心-大望京地区的地标性建筑。
SOM的创新设计根据北京的地理环境和气候特点，对当地的极端季节性气候和频繁的地震活动作出响应。
项目场地由主楼和两栋规模较小的配楼组成。
三栋大厦的椭圆形基底轮廓打破了毗邻的城市肌理的刚性几何形状，让周边的公园与项目场地完美融合在一起。
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，同时还构建出宁和、随地形起伏的人行步道。
塔楼的外观设计受中国纸灯笼启发，在连续斜肋框架构成的图案上安装宝石切割面造型的玻璃幕墙，使建筑立面在与天空和日光的互动中展现出变幻无穷的影像。
外骨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。
双层玻璃幕墙围护结构的两层表皮及其之间的间隙空间，可对外部的极端温度进行调节，使塔楼的整体能耗降低了23%，碳排放量降低18%。
塔楼平面两端的间隙空间向内扩展，形成了两个约122米高的中庭——高度几乎贯穿了这座31层摩天大楼的总高度。
这种“楼内楼”的设计方法也是这个项目可持续性设计策略的关键所在。
大跨度斜肋框架与双层围护结构的整合同时实现了高效节能的建筑围护结构和采光充足的室内无柱空间。
这座标志性建筑已获LEED金级认证，这也是建筑与结构工程设计团队之间协同合作，共同努力的成果。
中庭和开放式的楼层设计营造出一系列有吸引力的社交空间，从公共休息厅到屋顶花园——这些空间有助于在大楼的使用者之间建立一种社区意识。
保利国际广场于2017年竣工，再次有力地展示了SOM跨专业协作能力Client: Poly (Beijing) Real Estate Company Limited Size: 116,000 sqm Height: 161.2m Photography: Bruce Damonte SOM Services: Architecture, Structural Engineering Year of Completion: 2017Located midway between the Forbidden City and Beijing Capital Airport, the project was envisioned by the China Poly Group as a landmark for the emerging Dawangjing district, a new hub for globalbusiness. Its innovative design responds to the geography and climate of Beijing--a region prone to extreme seasonal climateand high seismicity.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.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.A second interior glass envelope creates a double skin with an interstitial space that mediates exterior temperature extremes, reducing the overall building energy consumption by 23 percent and carbon emissions by 18 percent. The interstitial space expands inward at the ends of the towers to create two soaring, 400-foot atriums—nearly the entire height of the 31-story skyscraper. This building-within-a-building approach is the key to the project’s sustainable design.The integration of the long-span diagrid structure with the double-skin envelope achieves two benefits at once: an energy-efficient building envelope and a column-free interior filled with daylight. While traditional Chinese paper folding patterns provided the inspiration for the form, it was the concerted effort of an integrated architecture and engineering team that put the iconic building on track for LEED Gold certification.The atria and open floor plates also make room for inviting social spaces, from shared lounges to a roof garden, that helps to build a sense of community among the people who work in the building. Completed in 2017, the building stands as a testament to the power of collaborative, integrated design.NO.208 世界建筑导报 7980WORLD ARCHITECTURE REVIEW 设计事务所 THE DESIGN FIRMNO.208 世界建筑导报81。
