巴伐利亚镇因泽尔主办了2011年世界单人速滑锦标赛。为了创造世界一流的比赛条件，通过建造高性能的智能屋顶结构，对现有的室外速滑道进行了升级。这一改进的竞技场可容纳多达7，000名观众，并为大规模的世界级比赛以及定期的季节性速滑训练提供最大的灵活性。

The Bavarian town of Inzell hosted the World Single Distant Speed Skating Championships 2011. To create the world-class competition conditions required for this event, the existing outdoor speed-skating track was upgraded through the construction of a high-performance intelligent roof structure. This improved arena can accommodate up to 7,000 spectators and offers maximum flexibility for large scale world class competitions as well as regular seasonal speed-skating training.

这座200米长、90米宽的竞技场是一个独立的大跨度结构，没有内部柱。运动员和观众可以通过连续的玻璃立面欣赏巴伐利亚阿尔卑斯山的全景，这是云状屋顶和流入景观的混凝土看台之间的透明地带。同时，过路人可以看到体育场的内部，并能瞥见日常活动。

The 200 meter long and 90 meter wide arena was planned as an independent wide-span structure, free of interior columns. The athletes and spectators can enjoy panoramic views of the Bavarian Alps through the continuous glass facade which stands as a transparent band between the cloud-like roof and the concrete grandstands that flow into the landscape. At the same time, passers-by can look into the stadium interior and catch a glimpse of daily activities.

屋顶本身体现了一个精确设计的内部气候概念，以确保优化的活力，经济和可持续运行的冰轨道的基础上，每天。在底部，屋顶安装了一个“低E”膜，伸展在10米高的木材和钢桁架的下部绳索之间。这种工程织物的功能是将冰本身的冷热辐射反射到速度轨道上，从而保持冰面的低温。同时，这种薄膜最大限度地增加了从屋顶的17个大北面天窗流入体育场的漫射日光的数量。

The roof itself embodies a precisely designed interior climate concept that ensures optimized energetic, economic, and sustainable operation of the ice track on a daily basis. On the underside the roof is fitted with a “Low-E” membrane stretched between the lower cords of the ten-meter high timber and steel trusses. The function of this engineered fabric is to reflect the ice’s own cold thermal radiation back onto the speed track, thus maintaining the low temperature of the ice surface. Simultaneously, this membrane maximises the quantity of diffuse daylight that streams into the stadium through the roof’s seventeen large north-facing skylights.

一些现有的支助建筑物也进行了升级，以便将它们纳入竞技场最佳精力充沛性能的总体概念。它们设有体育场主任办公室和培训人员办公室，以及用于冰维护设备的车间和空间。主要的技术工厂和宽敞的更衣室都在冰场水平的入口大厅下面。

A number of existing support buildings were also upgraded in order to integrate them into the arena’s overall concept of optimum energetic performance. They accommodate offices for the stadium director and the training staff, as well as workshops and spaces for the ice maintenance equipment. The major technical plants and extensive changing rooms are discretely located below the entrance concourse at the level of the ice field.
