现代的地域性

深圳的热带气候特征需要全新的办公楼设计方案。我们面临的挑战是，如何在一个热带气候条件下创建舒适的工作环境，同时减少能源消耗。典型的现代办公楼构筑做法通用于全世界，它的优点是有着实用的楼层布置以及经济的结构体系。但是，在热带气候条件下，玻璃幕墙立面往往会导致使用空调带来的大量能源消耗，带有涂层的窗户也使视野受到一定影响。要在这种条件下营造舒适的工作环境，应该具有以下两个条件：避免直射太阳光以及室内空气除湿。

我们的办公楼设计，基于高效出色的楼层方案，外观根据当地气候条件进行了改进及优化，通过大幅度改变建筑表皮外立面的方式来提高建筑的整体可持续性能。

设计的进化

由玄武岩组成的曲线形墙面来源于熔岩在慢速冷却过程中形成垂直岩柱的天然几何形态。

棕榈叶般的褶曲结构则出于适应外部环境的需要。棕榈表面的褶曲使建筑拥有了更轻盈的表皮，并具有一定的结构刚性和弹性。形成曲线的导流叶片会将水引导到建筑的尽端。

形似灯笼的折纸结构设计灵感来自于自然界不断演进的植物。

为了向工作人员提供功能灵活且具备足够采光的工作区域，具有高效性的摩天大楼应运而生。然而，到目前为止，普通摩天大楼的设计只是提供了空气调节及采光，却忽略了环境影响或能源短缺的情况。

新型的可持续摩天大楼需要在保留灵活性、日光、视野、密度以及可用性的同时，不断发展尝试新因素，例如，将自然采光最大化与日光直射最小化相结合， 从而大幅度减小制冷的需求。

我们建议将深圳能源大厦建造为首个新型可持续性办公楼，充分利用建筑表面与日光、空气、湿度以及风速等外部因素，以此为源头，创造无比舒适及高品质的内部空间。

深圳能源大厦将从传统的摩天大楼中脱颖而出，完成一项顺应自然而非强制性的设计蜕变。□

Modern Vernacular

The tropical climate of Shenzhen calls for a new approach to designing office buildings. How can we create comfortable working spaces in a tropical climate while reducing our energy consumption? The construction principle of the typical modern office tower is replicated all over the world. It has the advantage of a practical floor plan, and economical structural system. But in tropical conditions the glazed curtain wall facades normally result in high energy consumption for air conditioning and poor views through coated windows. To achieve a comfortable working environment in these conditions an office building would especially need two things: Shading from direct exposure to sunlight, and dehumidification of interior air.

We are proposing a tower based on an efficient and well-proven floor plan, enclosed in a skin specifically modified and optimized for the local climate. We propose to enhance the sustainable performance of the building drastically by only focusing on its envelope, the facade.

Design evolution

The rippled walls of basalt rocks have evolved naturally from the geometric behavior of lava cooling at very slow speeds into vertical compounds of rocky columns.

The folded structure of a palm leaf has evolved by adapting to the requirements of the exterior environment. The folded ripples in the surface of the palm provide a light sheet of material with structural rigidity and flexibility. The vanes along the ripples channel water to the extremities of the structure.

The origami like structure of a paper lamp is designed inspired by the ingenuity observed in naturally evolved plants.

The skyscraper has evolved as an economically efficient way to provide flexible, functional and well illuminated work spaces for dense populations of professionals. It has however evolved at a time when air conditioning and electric lighting were merely seen as modern solutions to modern demand, with no thought of the environmental consequences or energy shortage.

Today the skyscraper needs to evolve into a new sustainable species. It must retain its highly evolved qualities such as flexibility, daylight, view, density and general usability, while evolving new and untested attributes such as ways of combining maximum daylight exposure with minimal sunshine exposure or integrated ways of limiting the need for cooling.

We propose to make the Shenzhen Energy Mansion the first specimen of a new species of office buildings that exploit the buildings interface with the external elements－sun, daylight, air humidity, wind － as a source to create a maximum comfort and quality inside.

The Shenzhen Energy Mansion will appear as a subtle mutation of the classic skyscraper－a natural evolution rather than a desperate revolution.□
