架构师提供的文本描述。2008年6月，一场洪水席卷了爱荷华州的雪松急流，把市中心的中央图书馆灌满了8英尺的水。在这场自然灾害之后，城市聚集起来建造一个新的中央图书馆，它将成为城市核心的一个活跃的中心，拥抱21世纪技术的变革，并将建筑的环境影响和长期运营成本降到最低。

Text description provided by the architects. In June 2008 a flood swept through Cedar Rapids, Iowa filling the city’s downtown central library with eight feet of water. In the wake of this natural disaster, the city rallied to build a new central library that would be a dynamic center of the city’s urban core, embrace the transformational shifts of 21st Century technology and minimize the building’s environmental impact and long-term operational costs.

新址距离前洪水泛滥的设施只有几个街区之遥，位于洪泛区之外，并被定位为城市公园的锚。图书馆的设计抓住了这个机会，创建了一个城市广场，并将充满活力、活跃的图书馆空间定位于此，因此巨大的玻璃展厅突出了图书馆对社区的服务。

The new site is a couple blocks from the former flooded facility, outside the flood zone’s reach, and positioned to be an anchor to the city’s urban park. The design of the library embraces this opportunity by creating an urban plaza and positions the vibrant, active library spaces so the large expanses of glass highlight the library services to the community. 

从外部看，图书馆的活动主要是通过在一楼和二楼的建筑周围包裹的地板到天花板玻璃的扩展，可视地连接顾客和行人。位于二楼和第三层的200座礼堂面向公园。礼堂舞台衬托着玻璃的墙壁，营造了变化的季节和城市景观的背景。当黑暗降临时，大礼堂周围的立面用60英尺1英尺的光板照亮了。这种光的语言是带着巨大的楼梯来承载的，楼梯的特点是照明的面板随着用户在楼梯上上下走动而做出响应。楼梯和灯光墙从外部是可见的，起一个动感雕塑的作用，生动地将图书馆内的活动传达给街道。

From the exterior, the activity of the library is prominently on display through expanses of floor-to-ceiling glass that wrap around the building on the first and second floor, visually connecting patrons and pedestrians.  A 200-seat auditorium situated on the second and third levels faces the park. The auditorium stage is set against a wall of glass creating a backdrop from the changing seasons and cityscape. As darkness falls, the facade surrounding the auditorium glows with 60 eight-foot-by-one-foot light panels. This language of light is carried inside with a dramatic monumental stair featuring illuminated panels that respond as users walk up and down the stairs. The stairs and light wall are visible from the exterior, functioning as a kinetic sculpture and vividly telegraph the activity within the library to the street.

新设计打破了员工与赞助人、图书馆与市民空间、员工部门之间的隔阂。入场后，顾客们进入了一个两层的中庭，它将所有的核心客户服务集中在一个枢纽和讲话系统中，使用户能够在大楼中定位并聚集在一起。一家咖啡厅和咖啡厅坐落在中心，吸引游客聚集、逗留和相互接触。从核心辐射的是儿童、青少年和成人小说领域。集合空间内外的视图几乎从每个有利位置都可以看到。二楼包括成人非小说集，一个大的可分割的会议空间，以及工作人员和行政办公室。三楼是礼堂的分店大厅，公众可以进入20，000平方英尺的绿色屋顶，这是LEED白金雨水管理战略的一个关键部分，并且已经成为图书馆的必经之路。

The new design broke barriers between the staff and patrons, library and civic spaces, and staff departments. Upon entry, patrons step into a two-story central atrium that brings together all of the core patron services in a hub and spoke system allowing users to orient themselves in the building as well as gather to meet. A café and coffee shop is nestled in the core, enticing visitors to gather, linger and engage with each other. Radiating from the core are the children’s, young adult and adult fiction areas. The views in and out of the collection spaces are seen from nearly every vantage point. The second floor consists of the adult non-fiction collections, a large dividable conference space, and staff and administrative offices. On the third floor is a break-out lobby for the auditorium and public access to the 20,000-square-foot green roof that was a key part of the LEED Platinum storm-water management strategy and has become a go-to spot in the library.

雪松急流公共图书馆的成功证明了下一代图书馆对社区的影响。新图书馆最令人惊讶的地方是社区以无法想象的方式接受和使用该设施的方式。它确实是一个参与性的图书馆。关于流通、会议室使用和计算机使用的指标已经远远超出了预期，并突出了一个新图书馆可能对一个社区产生的影响。

The success of the Cedar Rapids Public Library demonstrates the impact a next generation library can have on a community. The most surprising aspect of the new library is the ways in which the community has embraced and used the facility in ways unimagined. It truly is a participatory library. The metrics on circulation, meeting room use, and computer use have far surpassed expectations and highlight the impact a new library can have on a community.
