Carrying more than 18 million passengers in its first weeks, Riyadh Metro is the world’s longest driverless transit system—spanning 176 kilometres across 6 lines and 85 stations throughout Saudi Arabia’s capital. The King Abdullah Financial District (KAFD) Metro Station serves as a key interchange on the new network, with six rail platforms over four levels connecting with bus and park-&-ride services to create a multi-modal transport hub.

The KAFD Metro Station’s design prioritizes connectivity. Predicted pedestrian traffic has been modelled and structured to optimize internal circulation and avoid congestion, resulting in a three-dimensional lattice clad in ultra-high-performance concrete panels. The façade’s geometric perforations reduce solar gain as a contemporary reinterpretation of traditional environmental sheltering within the region’s vernacular architecture.

Providing optimal comfort at minimum energy demand, the station combines effective passive design features with a high-efficiency cooling system powered by renewables and automatically adjusts to differing passenger levels throughout the day – achieving LEED Gold certification by the US Green Building Council.

利雅德地鐵在啟用初期短短數週內便運送超過一千八百萬名乘客，作為全球最長的無人駕駛交通系統，全長達176公里，由六條線路與八十五個車站構成，覆蓋整個沙烏地阿拉伯首都。阿卜杜拉國王金融區（KAFD）地鐵站作為新地鐵網絡的重要換乘節點，擁有四層空間與六個站台，並與公交系統及停車換乘設施相連，形成高效率的多式聯運交通樞紐。

KAFD 地鐵站的設計理念以「連通性」為核心。設計團隊針對預期的行人流量進行模擬與結構性規劃，精準優化內部動線，避免人潮聚集與擁擠。最終建構出以超高性能混凝土板組成的三維網格結構，外立面採用幾何穿孔設計，有效降低太陽輻射，同時呼應當地傳統建築對氣候遮蔽的智慧，以現代手法詮釋地域精神。

車站整體在節能與舒適之間取得平衡，透過被動式設計策略與由再生能源驅動的高效冷卻系統，能依據不同時段的客流量自動調節能源使用，以最低能耗提供最佳體驗。該設計最終獲得美國綠色建築委員會 LEED 金級認證，成為利雅德城市現代化與永續發展的重要象徵。
