设计方：Tangram Gulf Tangram’s Qatar World Cup Stadium
这是由Tangram Gulf建筑事务所设计的卡塔尔2022国际足联世界杯体育场。这个有8万座席的新体育场可操控沙漠地区的气流，并结合邻近的水源来为整个结构提供自然蒸发降温。这个系统不消耗任何电能，在休馆期间仍可为邻近社区提供中心降温服务。整个设计综合了多项源自卡塔尔当地建筑的节能技术。在体育场的外表皮上有当地传统的Badgheer式开口，捕捉来的沙漠热风产生穿过建筑体的气流。为了防止热空气推开冷空气，设计者开发了一种凹凸嵌板。嵌板设计结合了斐波那契对数和西部地区沙漠蜥蜴的降温模式。这种蜥蜴可以移动身上的鳞片导流体表空气来加速冷却。这些凹凸嵌板将风流导离体育场上方的敞口，相似的流体力学案例是推动帆船前行的运动风。经由热质量和文丘里效应，气流在体育场的柱廊结构中加速通过，帮助降温。为了控制建筑体内空气流速，设计师引进了当地传统的暗渠(Qanat)式水管理系统。储水罐设置于体育场观众席墩台的下方，可稳定为体育场的“人工湖”供应凉水。低温空气通过人工湖水分蒸发产生，并由空心的预制混凝土构件导入体育场内部。能量模型分析显示：体育场采用的自然降温系统可使温度降至27-30摄氏度。实际建筑的预期温度将有可能低于国际足联(WBT)湿球温度26-29摄氏度的要求。

The new FIFA stadium for the Qatar 2022 World Cup will “sculpt” the desert region’s winds and combine them with nearby water sources to provide passive-evaporative cooling for the entire structure. The system will use no electricity， and it will also function as a central cooling facility for the neighboring community when it’s not being used as a sports venue. Recently unveiled by architecture firm Tangram Gulf， the design will incorporate various energy-saving techniques that draw from Qatar’s vernacular architecture. The 80，000-seat stadium features traditional Badgheer openings which enable the capture and manipulation of the wind. These are created in the outer layer of the stadium and positioned to allow the effective harnessing of hot winds to create air currents across the structure. In order to stop the hot air from pushing out the cool air the designers developed a “skin” of punctured panels. The skin was designed by combining the Fibonacci logarithms and the cooling mechanisms used by the desert lizards in the Western Region Desert—the lizards move their scales to direct wind over their bodies to accelerate cooling. The punctured louvers allow the wind to be directed away from the open top of the stadium in a similar way as simple fluid mechanics help push sailing winds forward on modern yachts. The colonnade helps to create cooling through both thermal mass and the Venturi effect which accelerates air pressure across colonnade structures. To help direct winds across the stadium at the correct velocity for the cooling to take place， the designers introduced the Qanat-traditional water management system. It is positioned beneath the terraces of the stadium in the form of storage tanks which provide a constant supply of cooled water to the stadium’s “lake”. It cools the air through evaporation which is then guided by the hollow prefab concrete structure through the building. Energy models show the passive cooling system deployed in the stadium can currently deliver between 27 and 30 degrees temperatures， but is projected to become even lower than the WBT(Wet Bulb Temperature of between 26-29 degrees) required by FIFA.图包下载
