大气照相机（Atmospheric Lens）是一件公共艺术品，嵌在加拿大多伦多旺市大都会中转站（Vaughan Metropolitan Centre Transit Station）的圆屋顶上。该公共艺术品的占地面积高达16,000平方英尺，将中转站凸面形的天花板打造成了一个动态的、立体主义的拼贴画，形象地展示了车站内的日常百态。当乘客进入“镜头”下方的空间并在其中来往穿梭的时候，他们的影像便会被反射在天花板上的面板中，成为了不断变化的大气环境中的一部分，从而实现了一种被动动力学的效果。具有战略意义的天窗与冬至夏至、春分秋分时期的太阳角度相对应，将两个层次的光线投射到车站的深处，照亮了这个十分缺乏日光的空间，形成了一种动态的视觉效果。
Atmospheric Lens is a public artwork integrated into the dome of the Vaughan Metropolitan Centre Transit Station in Toronto. Spanning 16,000 s.f. it dissolves the convex ceiling of the above-ground pavilion into a dynamic, cubist collage of reflections of life inside the station. Commuters moving under the “lens” complete the passive kinetic effect by being in and seeing their reflection in the panels, becoming part of the ever-changing atmosphere above. Strategic skylights align with solstice and equinox sun angles channel light two levels down into the depths of the station, kinetically illuminating a typical daylight-starved space.

本项目由建筑师和艺术家合力打造而成，从设计之初就具有优秀的设计概念和设计方法。艺术家用短短数月的时间讨论并设计出了概念草图，随后，建筑师则用建筑的方式来呼应并完善了他们的概念设计。例如，使用建筑构架本身的面板模块系统，将一系列镜面抛光钢板嵌入其中，排列在天花板的下表面上。本项目的设计团队由建筑师和12名专业的工程师组成，值得一提的是，这12名工程师分别来自声学、照明和结构工程等领域，而前文所提到的艺术家便曾是这支设计团队中的一员。因此，“大气照相机”装置在构思和实际建造上都将艺术与建筑完美地整合在了一起。
The project was a collaboration between the architects and artist from the onset ensuring a good fit of philosophy and approach. The artist developed and discussed conceptual sketches over the course of several months while the architect responded and refined their design. The mirror polished steel panels that line the underside of the ceiling for example, use a panel module inherent to the architecture of the structure. The artist was part of the design team which consisted of architects and 12 specialized design engineers (acoustic, lighting, structural, etc.) As a result, Atmospheric Lens was conceived and realized to be fully integrated with the architecture.

The Vaughan hub accommodates a wide range of multi-modal connections. The concourse level extends south under Highway 7 providing an unpaid pedestrian connection under this major road barrier. There is also a tunnel under Millway Avenue for safer pedestrian connections to the east. At the center of Highway 7 there is a connection up to the surface platforms for VIVA BRT running on dedicated lanes. The concourse level extends north providing direct access to the York Region Bus Terminal. The main subway entry pavilion is located within a narrow landscaped park that incorporates bicycle parking facilities and passenger pick-up.

车站运用了一系列低维护成本且耐用的可持续性材料，如（建筑外露的结构钢材）、建筑混凝土、锌制屋顶板和不伤害鸟类的幕墙系统等，共同塑造了车站的主要色调和特点。该设计团队共实现了三个主要的加拿大绿色建筑标准（TGS, 即Toronto Green Standards），通过采取使用绿色屋顶、收集雨水和捕获与水径流等措施以减少城市热岛效应。此外，设计团队还使用软质的景观，同时减小车站建筑的表面积，以降低周围环境的表面温度。
Low- maintenance, durable and sustainable materials such as AESS (architecturally exposed structural steel), architectural concrete, zinc roof panels and a curtain wall system with bird-friendly screens formed the main palette for the station. The team addressed three main TGS (Toronto Green Standards) requirements including urban heat island reduction by use of green roofs, storm water retention, and storm water run-off capture. In addition, the use of soft landscaping and the reduced surface of the entrance building structure allow for a reduction in ambient surface temperatures.

该车站是旺市未来的城市二度发展计划中建设新商业区的重要催化剂。设计团队与客户和来自不同城市的代表密切合作，共同开发和整合该车站，以适应当前和未来的城市发展。设计团队在本项目中所面临的主要挑战是构想车站周边可能发生的一个全新的城市环境，并打造一座能够成为该环境中的焦点和组织性元素的标志性建筑。该车站便是一个典型的例子，它向人们展示了一个新的交通系统是如何改善城市的交通并积极地为城市增加额外价值的。

The station is a catalyst for future urban redevelopment for a new commercial district at the City of Vaughan. The team worked closely with the client and representatives from different municipalities in developing and integrating the station to both current and future development of the urban realm. The team was challenged to imagine a new city around the station and create an iconic headhouse that would become a focal point and organizing element. This station is an example of how the sensitive introduction of new transit systems can actively add value to a city in addition to improving mobility.

基础设施需要以人的尺度和活动为根本，同时兼具审美要求。然而，在构造和表达方面，某些基础设施建筑有时候会给人一种过于功利且毫无人情味的感觉。在这一方面，旺市大都会中心在其功能、美学和实用性方面都堪称典范。通过整合大量的公共艺术作品并积极呼应乘客和使用者的习惯，该车站成为了一个吸引人的、令人难以忘怀的场所，为乘客们带来了一段轻松难忘的旅途。
Architecture for infrastructure is sometimes utilitarian and inhumane in its construction and expression. Vaughan Metropolitan Centre seeks to be exemplary not only in its function but in its aesthetics and ease of use as well. By incorporating a large work of public art and responding to the patterns of passengers and users, the station is an inviting and memorable place that seeks to bring light and moments of levity to commuters.
