現代的地域性

深圳的熱帶氣候特征需要全新的辦公樓設計方案。我們面臨的挑戰是，如何在一個熱帶氣候條件下創建舒適的工作環境，同時減少能源消耗。典型的現代辦公樓構筑做法通用于全世界，它的優點是有著實用的樓層布置以及經濟的結構體系。但是，在熱帶氣候條件下，玻璃幕墻立面往往會導致使用空調帶來的大量能源消耗，帶有涂層的窗戶也使視野受到一定影響。要在這種條件下營造舒適的工作環境，應該具有以下兩個條件：避免直射太陽光以及室內空氣除濕。

我們的辦公樓設計，基于高效出色的樓層方案，外觀根據當地氣候條件進行了改進及優化，通過大幅度改變建筑表皮外立面的方式來提高建筑的整體可持續性能。

設計的進化

由玄武巖組成的曲線形墻面來源于熔巖在慢速冷卻過程中形成垂直巖柱的天然幾何形態。

棕櫚葉般的褶曲結構則出于適應外部環境的需要。棕櫚表面的褶曲使建筑擁有了更輕盈的表皮，并具有一定的結構剛性和彈性。形成曲線的導流葉片會將水引導到建筑的盡端。

形似燈籠的折紙結構設計靈感來自于自然界不斷演進的植物。

為了向工作人員提供功能靈活且具備足夠采光的工作區域，具有高效性的摩天大樓應運而生。然而，到目前為止，普通摩天大樓的設計只是提供了空氣調節及采光，卻忽略了環境影響或能源短缺的情況。

新型的可持續摩天大樓需要在保留靈活性、日光、視野、密度以及可用性的同時，不斷發展嘗試新因素，例如，將自然采光最大化與日光直射最小化相結合， 從而大幅度減小制冷的需求。

我們建議將深圳能源大廈建造為首個新型可持續性辦公樓，充分利用建筑表面與日光、空氣、濕度以及風速等外部因素，以此為源頭，創造無比舒適及高品質的內部空間。

深圳能源大廈將從傳統的摩天大樓中脫穎而出，完成一項順應自然而非強制性的設計蛻變。□

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.□
