高达308米的广发证券总部大厦

广发证券总部是一栋308米的超高层办公大楼，位于中国广州的珠江新城。这栋地标性建筑位于景观公共广场上，该广场是附近的新金融园区。

该塔楼轻微旋转偏离城市轴网，将建筑主体与周围环境区分开来，同时在底层创建了一个僻静的聚集区。

塔楼的朝向垂直于以广州塔为中心的珠江新城轴线，建立了重要的视觉联系，将珠江新城与广州CBD连接起来。

Guangfa Securities Headquarters is a 308-meter tall super high rise office tower located in the Zhujiang New Town district of Guangzhou, China. The landmark building is set on a landscaped public plaza that serves as a new financial campus in the neighborhood. By rotating the building off the urban grid and tapering the facade, the tower design distinguishes itself from the surroundings while creating a secluded gathering area at the base. The tower orientation is set perpendicular to the more centrally located Canton Tower, creating an important visual connection that links Zhujiang New Town with Guangzhou CBD.

超高层塔楼采用了一种复合结构，是钢筋混凝土核心筒和钢管混凝土柱之间的结合，以及在避难层设置桁架梁支撑系统。

塔楼的剪力荷载都转移到核心筒，而桁架梁支撑系统及建筑的八个角柱让首层的八个圆柱直径只有1100mm。

通过在建筑的30层引入空中大厅，可将核心筒的尺寸最小化，该大厅允许将不同的电梯组有效地堆叠在一起，以使用相同的电梯井道。

The super high rise tower used a composite structure which was a combination between a steel reinforced concrete core and steel tube columns along with an outrigger support system at the upper technical floor. All building shear loads are transferred to the central core and the outrigger system allows the building’s eight corner columns to be remarkably filigran at base in diameter of 1100mm. The size of the structural core is minimized by introducing a sky lobby on the 30thfloor of the building that allows different elevator groups to be stacked efficiently above each other in order to use same elevator shafts.

塔楼项目由空中大厅分为上下两个部分。低部楼层是对外租赁的办公室，而高层，上部是广发证券总部的专用办公空间。

中央十字布局的设计有效组织了公共流线，并能将卫生功能重置到未使用的电梯组中，从而使核心筒保持其紧凑性。

The tower program is divided into two parts by the sky lobby. In the lower part are situated rental office floors and the upper part of the tower are the headquarter office floors of Guangfa Securities.

The central cross core type design helps significantly to decrease the public circulation areas and helps to relocate of all sanitary functions into the unused elevator groups lobbies and thus the core maintains its compactness.

塔楼的外部分三个关键部分：一个高耸的入口大厅，改善了与周围环境的联系；一个空中大厅，提供公共休息室，增强垂直交通；一个标志性的冠顶，融入了广州城市天际线。

在覆盖率仅有30%的前提下，我们通过缩小塔楼下部占地面积，进一步优化了塔楼的底部。每个楼层可以容纳多达8个中小型公司租赁的独立办公室。

在塔楼的上部，即总部办公层，在减少一些电梯组后，核心筒尺寸进一步缩小了，以允许总部办公室有更多的可用面积。

在总部办公区的北侧，引入了连续的中庭空间，以便让更多的阳光进入。室内楼梯创造了中庭空间的垂直连接，改善了不同办公部门之间的垂直交通。

建筑顶部有一个舒适的空间，提供了一个员工可以放松、社交和非正式交流的公共区域。

整栋塔楼的平面设计都是为了最大限度地利用自然光线，同时创造开放、舒适、宽敞和健康的办公环境。

The external form of tower is articulated by three key zones: a soaring entrance lobby that improves connectivity with the surroundings, a sky lobby that offers a communal lounge and enhances vertical circulation, and an iconic crown that defines the tower's presence in Guangzhou city skyline. With only 30% site coverage allowed by zone regulations, we further optimized the base of the tower by tapering the width of the building footprint as it nears the ground. Every floor plan can accommodate up to 8 individual offices that smaller companies could rent out. At the upper part of the tower where are located the headquarter office levels, the tower core size is further reduced due to the less required elevator groups. This has a direct positive impact by allowing to have more usable floor area at the upper floors of the office headquarters. On the north side of the headquarter office zone, continuous atrium spaces have been introduced in order to allow more daylight to enter in the offices. Convenient indoor stairs create vertical connections in the atrium spaces which improve the vertical indoor office circulation between different office departments. An amenity space tops the building, offering a public zone where employees can relax, socialize and communicate informally. Throughout, the floorplans are designed to maximize natural light while creating open, comfortable, spacious and healthy office environments.

立面设计被设想为一个单一的系统，通过调节来表达塔楼的不同功能区。这种定制的竖框立面系统应用于整栋建筑，创造了整栋建筑立面的美学统一，并最大化了成本效益。立面的竖框轮廓从40毫米到80毫米逐渐变细，这使得它们不那么显眼和可见，让更多的阳光进入整个办公大楼的办公空间。

整个过程中，立面通过创造建筑内外的连续性来推动室内空间的设计。塔楼底部的雨篷设计反映在大厅天花板的重叠板面上。

竖框的深化设计在室内与定制设计的内墙转接器配合使用，该转接器允许内部轻质隔墙固定在竖框上。

在天空大厅，竖框向室内变形延伸，在室内定义了一个高耸的四层高空间，最大化了城市天际线的视野。在塔楼冠顶部，竖框覆盖着空中休息室的内部空间。

The facade design is conceived as a single system that is modulated to articulate distinct functional zones of the tower. This customized vertical mullion profile facade system is applied along the entire length of office tower and creates an aesthetic unity across the building facades and maximizes the cost-effectiveness. The facade mullion profiles are tapering outward from 40mm to 80mm, which makes them less dominant and visible and allow more daylight to enter inside the office spaces in the entire office tower. Throughout, the facade drives the design of interior spaces by creating a continuity between the inside and outside of the building. The design of the canopy at the base of the tower is reflected in the overlapped planes of the lobby’s ceiling. The mullions are developed to fit with a custom-designed adaptor that allows interior partitions to be tied into the facade. At the sky lobby, the mullions recede into the interiors, defining a soaring quadruple-height space at the perimeters of the plan that maximize views out over the city skyline. At the tower’s crown, the mullions sheathe the interior spaces of the sky lounge.

JKP带领着一个由工程师、制造商和可持续发展顾问组成的专家团队，从最初的概念设计阶段就着手设计整合高度复杂的建筑系统，以减少建筑的碳排放，并对员工的工作效率和办公环境产生了直接影响。

高效的建筑平面，优化的结构和核心筒设计，沿着室内中庭空间分布，有助于改善办公质量和租户体验。

弧形的外立面层间板吸收和过滤外部空气，有助于增强室内自然通风，提升办公空间的舒适性。

整个外立面采用高性能、Low-E彩釉玻璃，来减少太阳辐射，同时保持视野和采光。

挤压成型的竖框型材和覆层面板由回收铝制成，增强了环境的可持续性，同时保持了与全球金融领导者相符的立面品质。

Leading an expert team of engineers, manufactures and sustainability consultants, Jaeger Kahlen Partner managed to integrate from the very initial stage of concept design highly sophisticated building systems that reduce the building’s environmental footprint and have a direct social impact on employee’s well-being and productivity. Efficient building floor plate with optimized structural and core design along indoor atrium spaces helped improve the office work qualities and tenants experience. Curved facade spandrel panels draw in and filter outside air which helps to enhance the indoor natural ventilation and improve office spaces thermal comfort. The entire facade uses high-performance, Low-E frit printed glass that reduces solar heat gain while maintaining views and daylighting. The extruded mullion profiles and cladding panels are built of recycled aluminum alloys, enhancing environmental sustainability while maintaining the level of finish quality appropriate for a headquarters for a global leader in the world financial economy.

在基地西侧有一个标志性的裙楼作为贵宾室，其精巧的水景和令人印象深刻的景观，广发证券大厦融入了宏观的城市肌理中，为城市提供了互动的社交空间。建筑设计打破了二元框架，将形式与功能整体的融合在一起。

这座超高层办公大楼再次证明了我们从其扎根于城市文脉概念，并将建筑细节、立面系统和内部整合成一个完整的、令人难忘的设计。

Supported by a signature annex podium on the west for VIP lounge, with reflective water bodies and an impressive landscape, Guangfa Securities Headquarters integrates into the larger urban fabric and provides interactive social space to the city. The design surpasses dualities and combines form and function in a holistic approach. The super high rise office tower re-affirms our process of evolving concept from its rooted urban origins and integrating architectural detailing, facade systems and interiors into a holistic and memorable design.
