Ledding Library / Hacker Architects

由专筑网小R编译

全新的Ledding图书馆面积为20000平方英尺（约1858平方米），建筑位于美国俄勒冈州密尔沃基市的边缘地区，周边有湿地自然区域、城市公园，以及市政厅，设计方案希望能够为图书馆带来亲密的空间氛围，表达密尔沃基城市历史、社区以及市中心的核心地位，同时充分地利用周边自然环境，建筑形式的灵感来源于河流的运动形态，蜿蜒穿过场地，保留场地橡树以及水域的景观视线，建筑的室内外都应用了大量木材，让图书馆和周边环境融为一体，创造出温暖、热情，且充满活力的空间氛围，这座图书馆的主要设计原则由图书馆员工、社区成员，以及市议会共同定制。

Text description provided by the architects. The new 20,000-square-foot Ledding Library occupies a unique position at the edge of downtown Milwaukie, Oregon, between a wetland natural area, a city park, and City Hall. The design aims to create a civic presence for the library, reflecting its esteemed position in Milwaukie’s history, community, and downtown core, while taking advantage of the unique natural setting. Its form draws inspiration from the natural movement of rivers, bending across the site to capture sweeping views of the neighbouring heritage Oak trees and waterway. Extensive use of wood on both the exterior and interior help to blend the library with its surroundings, creating a warm, welcoming, vibrant atmosphere. The vision for the new library was driven by four main principals developed with library staff, community members, and city council.

原有的图书馆于1962年开放，这里曾经是Florence Olsen Ledding的故居，建筑师在原有的建筑上进行了扩建，增加了结构体系和公共设施，通过设计的方式提升了建筑的可达性和功能的灵活性，而在现有的场地上进行建筑重建的重点则在于充分利用场地的特征，这里周边有着景观池塘和Willamette河，停车场位于场地西侧边缘，和周边的公寓建筑形成空间功能上的分隔，同时也强调了景观自然区域，建筑东立面的大型开窗外侧遮挡着橡树，这里设置由阅览室，人们可以直接看到橡树和水池，除此之外，西侧立面也进行了隔热处理，这里的窗户较为狭窄，雨棚较宽，形成更多的遮阳区域。

The original library opened in 1962 and occupied the donated, former home of Florence Olsen Ledding. Three additions were added to the original house creating structural, and utility complexities and challenges for accessibility, library operations, and flexibility. The decision to build new on the existing site shifted focus to capitalizing on the site’s strongest attribute: its adjacency to a scenic wetland pond and tributary to the Willamette River. The parking lot was reconfigured to run along the full western edge of the site, buffering the adjacency to neighboring apartment buildings and consolidating landscaped and natural areas to the east, along the waterway. Large windows along the eastern façade, shaded by large oaks, align with seating areas for reading with direct views out to the trees and pond. Thermal gain is controlled on the western facade with narrower windows and a broad entry canopy, providing afternoon shade.







内部开放式空间环绕有员工空间、大型社区用房、小会议室，以及建筑服务用房，使用者从建筑的中央进入，周围有着橡树和水池，成人区域和儿童区域相对分隔，入口也相对独立，从而做到声学和功能上的区分。起伏的天花板形式的设计灵感来源于水流，具体的几何形态受到了外部条件的影响，比如悬挂的橡木和内部空间的塑造。

The interior open library wraps around staff spaces, a large community room, small meeting spaces and building services. Patrons enter at the center of the building, welcomed by the prominent view to the Oaks and neighboring pond. Adult and children’s areas are pulled apart into the opposing reaches of the building form for acoustic and programmatic separation. The undulating ceiling form takes inspiration from the flow of water, the specific geometry being driven by exterior conditions and influences, such as the overhanging Oak canopy, as well as interior space shaping.





图书馆保留这样的愿景，建筑拥有高效的循环辐射面板机械系统，用于空间的加热与冷却，同时保持空间的开放，窗户的位置和尺寸也针对阳光和热控制进行了优化，建筑还设置有40kW光伏面板，抵消了能源的消耗，图书馆整体的紧凑型热设计符合了2030挑战标准。

Holding true to the vision, the library has a highly efficient hydronic radiant slab mechanical system for heating and cooling the open library space. Window placements and sizes are optimized for daylight and thermal control. A roof-mounted, 40kW PV array further offsets energy use. The library's tight thermal envelope makes the building 2030 Challenge-compliant.
