架构师提供的文本描述。自行车启发了维罗赛马场的概念。自行车是一个巧妙的人体工学和空气动力学对象，它被磨练成无与伦比的效率和美丽。从设计过程开始，我们就想把设计的创造性和严谨性运用到自行车的设计和制造中去。对我们来说，重要的是，这不是为了模仿，而是表现为对体育场功能需求的三维反应。通过运用相同的思维发展和形态发现的方法，体育场的美学和造型就直接从这个过程中显现出来。

Text description provided by the architects. Cycling inspired the concept for the Velodrome. The bicycle is an ingenious ergonomic and aerodynamic object which is honed to unrivalled efficiency and beauty. From the beginning of the design process, we wanted to apply the same level of design creativity and rigor of engineering that goes into the design and manufacture of a bicycle to the building itself. It was important to us that this not serve to mimic but rather that it manifest itself as a three-dimensional response to the functional requirements of the stadium. By applying the same thought developments and form-finding approach, the aesthetics and shape of the stadium emerged directly from this process.

维也纳赛马场包含6，000个奥运和遗产模式的席位，并以最少的转换包含了这两种环境。上、下两层座位是由主要的公共交通汇合处分隔开的，这是进入竞技场的主要入口，让观众在建筑物周围移动时，可以与跑道上的活动保持接触。大厅全上了玻璃，以便能看到建筑物内外的景致。它还有助于在视觉上把西红雪松覆盖的上碗从底层的房子后面隔开，这很大程度上是隐藏在美化的土堤后面，在建筑的东侧和西侧形成了一个视觉平台。

The Velodrome contains 6,000 seats in both Olympic and Legacy Modes and embraces both contexts with minimal transformation. The upper and lower seating tiers are split by the main public circulation concourse which forms the main point of entry into the arena and allows spectators to maintain contact with the action on the track as they move around the building. The concourse is fully glazed to allow views both into and out of the building. It also helps to visually separate the Western Red Cedar-clad upper bowl from the ground floor back-of-house accommodation which is largely hidden behind the landscaped earth berms that form a visual plinth at the eastern and western sides of the building.

奥林匹克执行局为该项目设定了若干具有挑战性的可持续性目标；通过仔细考虑和整合建筑、结构和建筑服务，设计已经满足或超过了这些要求。我们的建筑设计战略侧重于尽量减少对能源和水的需求，并将其纳入建筑结构，以减少对系统和基础设施的依赖。适用于主要自行车竞技场的采光策略就是这种方法的例证。与其投资于光伏电池板的屋顶或其他‘螺栓’技术，设计最大的日光被证明是一个更经济的解决方案，在减少碳排放方面产生了更大的好处。

The Olympic Delivery Authority set a number of challenging sustainability targets for the project; through careful consideration and integration of the architecture, structure and building services the design has met or exceeded these requirements. Our design strategy for the building focused on minimizing demand for energy and water and integrating this into the fabric of the building to reduce reliance on systems and infrastructure. The daylighting strategy applied to the main cycling arena exemplifies this approach. Rather than investing in photovoltaic panels on the roof of the or in other ‘bolt-on’ technologies, designing for maximum daylight proved to be a much more economical solution which yielded far greater benefits in terms of reducing carbon emissions.

因此，在开发和优化主竞技场的屋顶灯方面作出了很大努力，以便在一年的大部分时间里为培训目的提供充足的日光。采用特殊的扩散玻璃，以防止阳光在轨道上出现，并在建筑物内提供较高水平的漫射光。与智能控制系统相连的节能人工照明可用于为重大事件提供更高的照明水平。这实现了最佳的平衡，由于日光使用节省能源，而不引起过多的玻璃面积，这将损害建筑的热策略。

A great deal of effort was thus put into developing and optimizing rooflights in the main arena to provide sufficient daylight for training purposes for most of the year. Special diffusing glass was used to prevent patches of sunlight from appearing on the track and to give a high level of diffuse light inside the building. Energy-efficient artificial lighting linked to an intelligent control system can be used to provide elevated lighting levels for major events. This achieves the best balance between energy savings due to daylight use without incurring excessive glazing areas, which would compromise the thermal strategy of the building.

作为一个公共资助的项目，在公众眼中，竞争获胜的方案已经受到了无数轮价值工程。设计团队以积极的方式接受了这些建议，从而进一步提高了设计效率并加强了最初的概念。这不仅使设计在成本上保持在目标上，而且还确保材料、体现和运作的能量保持在最低限度。由于采用了结构高效的索网屋面结构，与更标准的屋顶形式相比，节省了大约1000吨钢。

As a publicly-funded project in the public eye, the competition-winning scheme has been subject to numerous rounds of Value Engineering. These were embraced in a positive manner by the design team, leading to further increases in the efficiency of the design and a reinforcement of the original concept. Not only did this enable the design to remain on target in terms of cost but it has also ensured that the amount of material, embodied and operational energy has been kept to a minimum. As a result of the use of the structurally-efficient cable net roof structure it has been calculated that approximately 1000 tonnes of steel have been saved compared to a more standard form of roof.

主竞技场是高度绝缘和完全自然通风在中、夏季，显着减少能源需求。通过广泛的计算模拟，改进了进风口和出风口的尺寸要求，以达到所需的通风水平。这些是无缝地集成到建筑物的正面，并结合暴露的热质量在战略位置，允许被动冷却的建筑物在温暖的季节。

The main arena is highly-insulated and completely naturally ventilated in mid-season and summer, significantly reducing energy demand. Extensive computational simulation was used to refine the size requirements for air inlets and outlets to achieve the required level of ventilation. These are seamlessly integrated into the building facades and in combination with exposed thermal mass in strategic locations allow passive cooling of the building in the warm season.

最后，雨水从屋顶收集起来，储存在护堤后面建筑物西端的地下。回收雨水用于提供WC/尿池冲洗和任何冲洗点，以及赛后完成的Velopark灌溉。在雨量少或需水量高的情况下，仅将公园范围内的非饮用水作为雨水系统的补充，并在整个建筑物内使用节水装置，预计Velo军事法庭的饮用水需求将每年减少75%。

Finally, rainwater is harvested from the roof and stored in the undercroft at the west end of the building behind the berm. Recycled rainwater is used to supply the WC/Urinal flushing and any wash down points, along with irrigation of the Velopark when completed post–Games. Using the park-wide non-potable water only as top-up for the rainwater system in periods of low rainfall or high water demand and the use of water saving fittings throughout the building the Velodrome is predicted to achieve an annual reduction of 75% in potable water demand.
