2020日本东京奥运会主体育场乌龙事件一直是建筑圈内的热点，日本将亲自选中的zaha方案撕票然后再重新组织竞赛选出本国建筑师方案。而在这经济，政治等多种因素博弈的复杂喧嚣之后，大多数竞赛方案概念面临的是被忽略。这次为大家介绍的 “KOFUN STADIUM”就是其中一个竞赛参赛落选方案。

▽DGT创作的体育场 “KOFUN STADIUM”

日本东京奥运会主体育场建筑师评审团主席安藤忠雄在2012年的竞赛召集文中提到：“我们必须创建一个希望之象征，从而为人类的未来照明。”，这个主会场肩负使命，还要成为下一代体育馆的榜样。在古代，体育场是利用地形，开方挖土而建。而现代，体育场多成为现代技术的表现物，做成一个天外来物的UFO状或者成为郊区中庞大但是平庸的存在。而东京奥运会的主体育场位于东京最核心的地段，它需要为人们以及下一代创造空间。

抱着这样的想法，DGT的建筑师希望创建一个坟一样的体育场 “KOFUN STADIUM”，忽略掉名字换个角度理解他们的意图，他们则是在东京中心基于大地建立一个纪念碑。这个纪念碑也是日本古代文明的丰碑，也与过去相连，比如现今已消失的明治时代纪念建筑外苑林。新的体育场将在城市中心创建出一片森林。

“We must create a place that serves as a symbol of hope and provides a light for the future of mankind.” An international competition for the New National Stadium of Japan started with this quote by Japanese architect and jury chair, Tadao ANDO, in summer 2012. The competition was to design what will become the main stadium for the Tokyo 2020 Olympic bid, and was open for the most innovative proposal for the next generation of stadia design from all over the world. In ancient times, the stadium was created by excavation of the earth to form a topography where people can gather. Today, the stadium has become more about the expression of modern technology, to make a sort of UFO or non site specific icon that is inevitably exiled to the outskirts of the city due to the large scale of its intervention. Since Tokyo is aiming to create a stadium in the centre of Tokyo, a ‘next generation’ proposal has to be installed to create a place for people.

DGT’s proposal in response to this theme was to create a “KOFUN STADIUM”, a manifestation of an earth-based monument in the centre of Tokyo. The KOFUN itself, being the largest constructed monument of ancient civilization in Japan, was to combine the Olympics as the world’s largest event of today, into one architecture. In addition, it was important to connect to the origin of the place, the memorial construction of the Meiji Empire, and the Meijijingu-gaien forest of 100 years ago, which has lost its place and meaning after WWII. Therefore, the proposal should re-generate a memory of place, creating a forest to preserve the power of nature on this land.

▽宛如一座大山，体育场为人们以及下一代创造绿色城市空间 The proposal seeming like a mountain create a forest to people and next generation.

▽体育场顶部。人们在屋顶花园上可以观赏城市盛景。 Roof garden provide spectacular view of Tokyo.

体育场可依据使用用途改造为奥运会会场，田径运动场和演唱会活动场所。场馆顶部可以伸缩的屋顶能让体育场适应各种天气条件。体育场是耗能大户，但这个被土壤覆盖的建筑具有极为优良的热工效应，能够实现低能耗的可持续运转模式，于此同时能够积极利用雨水，让森林繁茂，动物繁衍。精心设置的多孔通风道能够保证良好的通风。在过去，古坟是象征死亡的黑暗之地，而现在，这个球场却在光明中为人类的胜利庆祝。

这就是新一代的球场，面面俱到的联系着过去与未来，还具有永恒感。

The stadium can be transformed according to the event it is hosting, whether it is The Olympics, field sports or concert events, and features a retractable roof in order to use the facility in all weather conditions. A stadium consumes the majority of its energy during peak event time, therefore we propose to share this excess energy to the surrounding district during non-peak times. In addition, materials from the demolition of the existing stadium will become part of the mountain. Rainwater will be collected and redistributed as a fine mist to benefit the forest and organic matter on the roof.

This roof covering will firstly cool against the city heat, creating a porous wind route for natural air ventilation, but will also enable a recycling exchange for the damaged field ground with the grass on the stadium roof. The idea of an environmental energy dynamic that can positively create sustainable transformation between natural environment and artificial innovation. The original form of the KOFUN were found to be dedicated to “death”, to cover darkness in ancient times, and today’s stadium will instead be dedicated to openness, to “human triumph”, to celebrate in light.

A stadium of the next generation should combine past and future to create a place for people in the city, a place to be together for events and where it manifests a sense of timelessness. A place for all.
