Entrance

The new headquarters building for the Guosen Securities corporation in Shenzhen, China, has the objective to be efficient and cool. The new symbol for the dynamic corporation needed to be energy efficient and a pleasurable working environment.

In an effort to realize good views and direct daylight for every worker a compact floor plan of 1849m2 has been chosen as a basis, no workplace is further than 11 meters away from the façade. Stacking these floors leads to a 204 meter tall tower with a square floor plan and an elegant, slender volume.

Facade

The edges of each floor plate have been folded down with an angle of 35 to 55 degrees creating  shadow for the floor below and reducing the cooling demand of the building. Large glass fronts connect these louvers, offering the office workers excellent views of the surrounding cityscape.

The louvers vary in size according to the orientation, on the north side they are small whilst at the south side they are larger. The angle of the louvers allows for the addition of solar cells and reduces the energy demand of the building by 33 %. The louvers are also used for water collection to feed the grey water circuit. A lengthy water pipe system runs invisibly through the façade collecting the heat of the solar cells to heat up water.

The louvers are a logic façade element and at the same time they create identity for the tower which resembles a giant Chinese lantern.

At the collective parts of the building the louvers are lifted to allow for a larger glass front. The main entrance, the restaurant, the conference centre are clearly recognizable and offer double ceiling heights.

The building fits seamlessly into the urban surrounding; all sides of the ground floor have a commercial plinth or glass facades that connect inside and outside. The low rise volume next to the tower holds a shopping centre and a conference centre. Underneath the building a tunnel offers pedestrian access to a nearby metro station.

At the top of the tower, the double high executive lounge is situated. The façade has been opened to create a panoramic view towards Hong Kong Bay.

On two places in the tower, both in the top and in the lower section, two collective double height spaces have been created. They are designed as small amphitheatres that can be used for conferences and gatherings. They have terraced seating that allow for uninterrupted views over the city.

Night

深圳国信证劵新总部大楼是一个富有效率还很酷的塔楼。拥有一个生态节能，让人愉快的办公环境。每层面积不超过1849平米，单边进深小于11米，总高度204米，体形方正修长优雅。

部分楼层的楼板局部做了33—55°不等的倾角，给下层创造了阴影，减少建筑制冷能耗。同时可以在这些地方设置大面积的窗户，为办公人员提供周围城市优美风景。

建筑南侧的遮光百叶大于北侧，同时百叶的倾斜角度使得可以添加太阳能电池，从而减少了建筑33%的能耗。百叶板也可收集水用于中水系统。水循环系统通过太阳能发电的热量得到了加热。

百叶也是建筑外立面的主要元素，使得建筑看上去就像一个塔状的灯笼。建筑的有些部分没有设置百叶，以提供更大框的风景，比如主入口，餐厅，会议中心。同时这些部位的单层层高都较高。

建筑和城市紧密连接，一层是有着玻璃幕墙的沿街商业。群房里还有购物中心和会议中心。并设有隧道与地铁相连。在塔楼的高层两处分别设置了两个层高较高的公共空间，并在其中设置了梯田状的座位，可以用做小型会议，聚会，或者剧场等功能。同时可以在这里一览无余城市的大好风光。
