2018年8月12日，佩里·克拉克·佩里建筑师事务所(PCPA)揭晓了位于美国加利福尼亚州旧金山市，总面积达120万平方英尺的新作 – Salesforce 客运中心和其屋顶公园Salesforce公园。令人期待已久的客运中心沿Mission大街连绵延伸五个街区，直达旧金山金融区以南，是美国城市设计的新典范。PCPA的建筑设计展示了基于公共交通的高密度开发项目对可持续宜居城市的成功打造。未来，客运中心将包含11个公共交通系统及高速铁路系统，成为城市周边，州内城际乃至国家级的连接枢纽。
San Francisco, CA –Pelli Clarke Pelli Architects unveils the1.2 million square foot Salesforce Transit Center including its rooftop park, Salesforce Park. Stretching four blocks along Mission Street, one block south of the city’s Financial District, the long awaited Transit Center is a new paradigm for urban design in the United States. Pelli Clarke Pelli’s architectural design illustrates how a dense, urban, transit-based development can provide a sustainable and livable city. In the future, the Transit Center will link to eleven transit systems, high-speed rail, connecting the city to the region, the state, and the nation.

1989年Loma Prieta地震破坏了自1939年开放的旧金山环湾交通站，使城市需要一个全新的客运中心。Salesforce客运中心新项目于2010年破土动工，建成后将成为旧金山湾区主要的公交总站 ，以及未来的铁路终端。建筑工程由环湾联合权力机构（TJPA）主管。
Construction of the new Salesforce Transit Center was necessitated by the 1989 Loma Prieta earthquake, which damaged the original Transbay Terminal that opened in 1939. The new project broke ground in 2010. The Salesforce Transit Center will serve as the primary bus terminal – and later rail terminal – for the San Francisco Bay Area. The construction is governed by the Transbay Joint Powers Authority (TJPA).

早在2007年，PCPA在国际竞赛中凭借有力而创新的设计赢得了项目。项目启动十一年后，PCPA的宏伟愿景得以实现。 “当我们第一次讨论Salesforce 客运中心的设计时，我们认识到该建筑应该既是通往旧金山的门户，又能良好的支持与其相邻的建筑物。 我们致力于将这个大型构筑物打造得人性化又亲切。” 高级设计董事、PCPA联合创始人弗瑞德·克拉克（Fred Clarke）表示，“从宽敞明亮的进站大厅到占地5英亩的Salesforce公园，该建筑热情接纳并扩展了城市公共领域，欢迎大家来到这个新的城市中心。 它的外墙和公共艺术计划同时象征着湾区的创新和创造力。”
In 2007, Pelli Clarke Pelli Architects won the project contract with a powerful and innovative design. Eleven years after inception, the critically acclaimed firm’s vision is brought to life. “When we first addressed the design of the Salesforce Transit Center we saw that the building had to be both a gateway to San Francisco and a good supportive neighbor to the buildings adjacent to it. We were committed to the idea that this large-scale structure could be both humane and civilized,” commented Senior Design Principal Fred Clarke, FAIA, co-founder of Pelli Clarke Pelli Architects. “From its spacious light-filled Grand Hall to the five-acre Salesforce Park, the building embraces and extends the public realm, welcoming everyone to this new urban center. Its exterior wall and art program symbolizes the innovation and creativity of the Bay Area.”

Salesforce 客运中心将地方，区域和国家公共交通网络整合到一个高耸而光线充足的建筑中。 “光柱”是中央大厅的核心，它既支撑着建筑，又将阳光引入其核心，营造出温馨的城市空间。 从公园开始，穿越公交层和中央大厅，直到两层楼以下服务于加州火车系统和加州高铁系统的车站层，这个引人注目的结构体为客运中心的所有区域提供了自然光与通透视线。
Salesforce Transit Center draws together local, regional, and national transit networks into a soaring, light-filled building. The light column is the centerpiece of the Grand Hall which is both supporting the building and bringing daylight into its core, creating a welcoming urban space. Reaching from the park, down through the bus deck and Grand Hall to the train platforms two stories below grade for anticipated Caltrain and high-speed rail, this dramatic structure provides light and views to all areas of the Transit Center.

建筑的表皮轻微起伏，仿佛悬浮在街道上方，成为城市醒目一景。外墙的灵感来自着名的数学物理学家罗杰·彭罗斯（Roger Penrose）爵士发明的“潘罗斯铺砖法” 。 外墙用轻盈通透的手法围合了建筑，创造出一个在城市的许多位置都可以看到的轻云状结构。 在街道尺度上，众多的商店和咖啡馆吸引访客，并给社区注入活力。
Outside, visible from afar and floating above the street, is a gently undulating wall-inspired by the “Penrose Tiling” invented by famed mathematical physicist Sir Roger Penrose. The wall is both a veil and an enclosure creating a light cloud-like structure visible from many vantage points in the city. At street level, shops and cafes will draw visitors and energize the neighborhood.

占地5.4英亩的公共屋顶公园是Salesforce 客运中心的核心，被称为Salesforce公园。 郁郁葱葱的园景公园设有聚集空间，安静休憩空间，宽阔的草坪和可容纳800人的天然圆形剧场。餐厅和儿童游乐场穿插在景观之中。公园将开设多于12个入口点，并可于周围建筑通过连桥互通。 从红杉树到湿地沼泽，密集的植物群反映了湾区丰富多样的自然生态。
At the heart of the Salesforce Transit Center is the 5.4-acre public rooftop park, known as Salesforce Park. The lushly landscaped park features gathering spaces, places for quiet repose and a sprawling lawn with a 800-person-capacity natural amphitheater. Also woven into the landscape is a restaurant and a children’s playground. Multiple entry points, including bridges that connect to surrounding and future buildings, welcome visitors. The dense flora offers a wide variety of Bay Area ecologies, from redwood trees to a wetland marsh.

屋顶公园象征着PCPA和Salesforce客运中心对环境质量和可持续性的执着追求。该生态系统生长着600多棵树和16,000多株植物，每年可抵消高达12吨碳排放。客运中心还将大幅减少温室气体排放。预计每年的能源消耗将比美国现行2008年第24号节能标准还要低50％。建筑相关的碳排放量将减少约40％。由于公园的存在，客运中心的屋顶能够收集并再利用雨水，避免其通过下水道流失。客运中心的水资源再利用系统是在旧金山市的首例。它也是旧金山第一个带有屋顶湿地过滤系统的项目。得益于水资源的保护和再利用，项目每年将节省1390万加仑的水，减少17,000吨的二氧化碳排放。该项目有望在LEED 2009绿色建筑评估体系下获得金牌认证。
The roof top park is symbolic of Pelli Clarke Pelli Architects and Salesforce Transit Center’s commitment to environmental quality and sustainability. With more than 600 trees and 16,000 plants, the ecosystem will capture 12 tons of carbon annually. The Transit Center will also reduce greenhouse gas emissions significantly. The annual energy consumption is projected to be 50 percent lower than the 2008 Title 24 Energy Efficiency Standards. Its associated carbon emissions will be reduced by approximately 40 percent. The Transit Center’s roof, by virtue of having the park, retains and reuses storm water that would otherwise flow into sewers. The building’s water reuse system is among the first of its kind in San Francisco. It is also the first project in San Francisco with a rooftop wetland filtration system. This will save 13.9 million gallons of water and 17,000 tons of carbon dioxide each year due to water conservation and reuse. The project is on track to receive a Gold certification under the LEED 2009 rating system.

负责实施客运中心项目的公共机构 – 环湾联合权力机构（TJPA）- 定制了四个主要的与客运中心设计相结合的艺术品。 PCPA与艺术家们合作，融合了艺术与建筑，使公众更容易理解与亲近。 这些令人惊叹的视觉艺术作品包括：
占地近20,000平方英尺，大厅水磨石地板吸引游客和乘客进入流光溢彩的空间。设计元素包括加州罂粟花，月桂树和从当地生态环境中选取的宝石色蜂鸟。
滚动LED文字环绕椭圆形玻璃幕墙，照亮整个中央大厅，呈现一系列湾区和西海岸组成或有关的文字。
浇筑了聚合树脂和玻璃的铺地，可点亮的光具座，现场浇筑的混凝土铺地以及高处棱柱形光束与半透明的铺地和地面上设置的光具座相互辉映。同时，一系列照明的台架嵌入混凝土地面。这个明亮的环境为Shaw 巷的行人创造了独特的空间和感知体验。
由传感器触发的一系列喷水器呼应公园下方公共汽车的移动。 通过对水景的精心设计，1000英尺长的喷泉使公共汽车的到达和离开变得直观可见。

The Transbay Joint Powers Authority, the public agency charged with implementing the Transit Center project, commissioned four major artworks that have been integrated with the Transit Center’s design. Working in collaboration, Pelli Clarke Pelli Architects and the artists have blurred the lines between art and architecture, making both more accessible to the general public. The stunning visual art elements include:
Spanning nearly 20,000 square feet, the Grand Hall terrazzo floor draws visitors and commuters into the colorful, light-filled space. Design elements include California poppies, laurel and jewel-toned hummingbirds drawn from local ecologies.
Scrolling LED text wraps around the elliptical glass enclosure that illuminates the Grand Hall, presenting a range of texts composed in or about the Bay Area and the West Coast.
Cast polymer resin, glass pavers, illuminated benches, site-cast concrete pavers and overhead field of prismatic light fins interacts with translucent pavers and a series of illuminated benches set into a ground plane of concrete pavers. This luminous environment creates a unique spatial and perceptual experience for pedestrians in Shaw Alley.
series of water jets triggered by sensors responding to the movement of the buses on the level below the park. The 1000-foot-long fountain makes the arrival and departure of the buses visible and tangible through their choreographed effect on the water.
