架构师提供的文本描述。Salesforce大厦将是旧金山最高的建筑，与金门大桥和Transamerica大厦一起成为天际线的重要元素之一。2007年，佩利·克拉克·佩利赢得了一项设计塔楼和基地销售力量交通中心的国际比赛。这两座建筑合在一起，代表了在城市环境下公私合作和可持续发展的一种新方法。

Text description provided by the architects. Salesforce Tower will be the tallest building in San Francisco, joining the Golden Gate Bridge and the Transamerica Building as one of the skyline’s defining elements. Pelli Clarke Pelli won an international competition in 2007 to design the tower and the Salesforce Transit Center at its base. Together, the two buildings represent a novel approach to public-private collaboration and sustainability in an urban setting.

比赛由跨湾联合权力机构主办，这是一个由旧金山市为发展新的过境中心而设立的公共实体。为了资助这座建筑，在一次邀请的竞争中，部分土地被提供给开发商和建筑师团队出售。Pelli Clarke Pelli及其发展伙伴提交了一份侧重于可持续性、邻里发展和财务可行性的设计。

The competition was sponsored by the Transbay Joint Powers Authority, a public entity created by the City of San Francisco to develop the new transit centre. To help fund that building, part of the site was offered for sale to teams of developers and architects in an invited competition. Pelli Clarke Pelli and its development partner submitted a design that focuses on sustainability, neighbourhood development, and financial feasibility.

塔高326米(1，070英尺)，具有方尖碑的简单、永恒的形状，给这座61层的塔以细长、渐细的轮廓。墙壁由带有珠光金属口音的透明玻璃组成。这些水平和垂直的口音逐渐变细的深度，以突出弯曲的玻璃角落。墙壁从顶层升起，形成一个透明的树冠，似乎会溶入天空。雕刻在塔顶是一个垂直的小面，将在夜间照明。

Standing 326 meters (1,070 feet) tall, the tower has the simple, timeless form of the obelisk, giving the 61-story tower a slender, tapering silhouette. The walls are composed of clear glass with pearlescent metal accents. These horizontal and vertical accents gradually taper in depth to accentuate the curved glass corners. The walls rise past the top floor to form a transparent crown that appears to dissolve into the sky. Carved into the tower top is a vertical facet that will be lit at night.

在其基地，Salesforce塔直接连接到过境中心，该中心将容纳11个海湾地区的交通系统。在交通中心的顶部，与塔直接相连的是一个占地5.4英亩的公共公园，它将提供娱乐、教育和自然活动。公园有两个角色：一个是未来社区的支柱，另一个是该项目可持续设计战略的关键要素。

At its base, Salesforce Tower connects directly to the transit centre, which will house 11 Bay Area transit systems. On top of the Transit Center and linked directly to the tower is a 5.4-acre public park, which will offer recreational, educational, and nature activities. The park has two roles: the future anchor of the neighbourhood and a key element of the project’s sustainable design strategy.

塔楼的每一层都将集成金属遮阳伞，通过校准使光线和视野最大化，同时降低太阳增益。高性能，低发射率玻璃也将有助于减少建筑物的冷却负荷.冷却部分可以通过环绕塔基的换热线圈来提供。塔楼和中转中心还包括综合水回收系统。此外，高效率的空气处理器将吸收新鲜空气在每一层。

Each floor of the tower will have integrated metal sunshades, calibrated to maximize light and views while reducing solar gain. High performance, a low-emissivity glass will also help to reduce the building’s cooling load. Cooling may be provided in part by heat-exchanging coils wrapped around the tower’s foundations. The tower and transit centre also include comprehensive water recycling systems. In addition, high-efficiency air-handlers will take in fresh air on every floor.
