SOM’s Diagonal Tower in Yongsan International Business District of Seoul, South Korea, is a case study in efficiency – 343 meter tall tower successfully minimizes wind loads, reduces construction costs, provides dramatic views and meets strict energy codes by integrating massing, structure and performance. Moreover, it maintains necessary iconic skyline presence.

位于韓國首爾龍山國際商業區的 SOM對角塔是一個高效的案例研究 - 343米高的塔成功地將風荷載降至最低，降低了建筑成本，提供了引人注目的視野，并通過集合體量，結構和尺寸來滿足嚴格的能源規范性能。此外，它還保留了必要的標志性天際線。

The design of this landmark skyscraper, with glazed triangular facets, employs passive environmental control strategies within and on the fa?ade – sunshades are positioned at varying angles on each building exposure, horizontal, vertical, and diagonal, thus mitigating heat gain in the summer and permitting direct sunlight to warm the building’s interiors during Seoul’s cold winter months. Triple pane glazed exterior curtain wall decreases energy loss, therefore meeting Seoul Green Guidelines criteria while active chilled beam system surpasses traditional air driven systems, using water as a medium for transferring heating and cooling energy, which results in less energy consumption along with great environmental comfort for building users.

這個具有里程碑意義的摩天大樓的設計采用釉面三角形面板，在建筑外立面和外立面采用被動環境控制策略 - 遮陽篷在每個建筑物的暴露，水平，垂直和對角線上以不同角度定位，從而減輕夏季的熱量增加，并允許在首爾寒冷的冬季，陽光直射使建筑物的內部變暖。三層玻璃外墻幕墻減少能源損失，因此符合首爾綠色指南標準，而主動式冷梁系統超越傳統的空氣驅動系統，以水作為傳遞加熱和冷卻能量的媒介，從而減少能源消耗，同時具有極佳的環境舒適度為建設用戶。

Mixed-use high-rise, located at a prominent corner of the emerging Business District of Seoul, provides more than 170,000 square meters of open office space, sky lobbies with fitness center and cafeteria and a penthouse executive lounge at the top. This prestigious edifice also facilitates two retail pavilions and an ethereal glass multi-functional auditorium, defining pedestrian scale and incorporating the building into its context and the surrounding.

位于首爾新興商業區一角的混合高層建筑提供超過170,000平方米的開放式辦公空間，天空大堂設有健身中心和自助餐廳，頂層設有頂樓行政酒廊。這個著名的大廈還促進了兩個零售展館和一個空靈的玻璃多功能禮堂，確定了行人規模，并將建筑融入其環境和周圍。

Its primary visual element – the diagonal mega-frame structure, defines the form of the building, while cutting the wind forces and reducing the amount of steel by 25% over a conventionally framed building. Four massive piers support the building, therefore freeing the lobby which becomes the natural continuation of the urban plaza across.

其主要視覺元素 - 對角巨型框架結構定義了建筑物的形式，同時在傳統框架建筑中切割風力并將鋼材量減少25％。四個巨大的碼頭支撐著這座建筑，因此釋放了成為城市廣場自然延續的大廳。

It is clear that SOM’s goal is achieved – the Tower progressively addresses the critical issues associated with skyscraper design in an iconic and refined manner.

很顯然，SOM的目標已經實現 - 塔以標志性和精致的方式逐步解決與摩天大樓設計相關的關鍵問題。
