盐湖城的增长和发展与其矿业和工业历史密切相关，从淘金热初期的淘金热到目前美国最大的工业银行中心的地位。然而，近年来，这个城市试图使其经济基础多样化，以包括服务业和旅游业以及创意部门。在这样做的过程中，各种发展项目承担起了振兴市中心，把SLC建设成为商业中心和文化核心的任务。

Salt Lake City's growth and development is closely tied to its mining and industrial past, from the early days of the gold rush and mining activity to its current status as the largest industrial banking center in the United States. However, the city has tried in recent years to diversify its economic base to include services and tourism industries, as well as the creative sector. In doing so, various development projects have taken on the task of revitalizing the downtown and establishing SLC as not only a business center but also a cultural nucleus.

随着市中心人口的增长，商业社区的蓬勃发展，以及一个充满活力的新的零售中心，这座城市在许多方面都经历了复兴。我们的项目提供了一个机会，将不断增长的商业/零售中心和城市持久的历史核心与一个积极的文化和创新核心结合起来，这将增强城市的都市愿望。就目前的情况而言，该地区主要由办公楼、地面停车场和车库组成，这些建筑往往吞没了该地区的历史和文化建筑。

With a growing downtown population, a thriving business community, and a vibrant new retail core, the city is in many ways experiencing a renaissance. Our project presents an opportunity to unite the growing business/retail center and the enduring historic core of the city with an active cultural and creative nucleus that will enhance the metropolitan aspirations of the city. The site, as it currently stands, is dominated by office buildings, surface parking, and garages, which tend to engulf the more historic and cultural buildings of the area.

连通性-一种新的地面覆盖策略，视觉上将不同的环流空间拼接成一个具有凝聚力和易于识别的运动表面。此外，场内存在的各种非正式路径和轨迹被正规化为安全、光线充足的交通空间，从而形成了一条主要的东西轨迹，将场地内的各种文化项目连接在一起。这条中间街区的文化走廊经常被南北连接相交，因此形成了一套漏洞百出的城市流通系统，它不仅将场内各种不同的文化建筑连接起来，而且还将其与更大的环境连接起来。

Connectivity A new ground cover strategy visually stitches together the various circulation spaces into a cohesive and easily recognizable movement surface. In addition, the various informal paths and trajectories that exist within the site are formalized into safe, well-lit spaces for circulation.As a result, a major East-West trajectory emerges which connects the various cultural programs within the site together. This mid-block cultural corridor is regularly intersected by North-South connections, hence creating a porous system of urban circulation that not only connects the various disparate cultural buildings within the site, but also connects the site to its larger context.

主广场

除了物理连接基础设施之外，还引入了一个新的数字信息系统，在网站、城市的活动甚至全球信息流之间建立了更大的联系。信息站被放置在交叉口、主要公共空间和文化走廊的战略位置，以提供WiFi热点以及有关69-70站点内活动的信息、这些活动的票务服务、全市导航地图和交互式公共交通时间表。这些信息站和现场内的其他城市设备(用于座位、照明等)还通过集成太阳能电池板发电提供移动设备充电能力。数字信息系统和物质流通空间共同构成了一个连接城市结构，产生并加强了内部和外部的联系。

In addition to the physical connectivity infrastructure, a new digital information system is introduced, creating a larger connection between the activities of the site, the city, and even the global flows of information. Info-Stations are placed in strategic locations at intersections, major public spaces, and along the cultural corridor, to provide WiFi hotspots as well as information regarding the events within the 69-70 site, ticketing services for these events, city-wide navigation maps, and interactive public transportation schedules. These info-stations and other urban equipment within the site (for seating, lighting, etc.) also provide mobile device charging capabilities through integrated solar panel energy generation. Together, the digital information system and the physical circulation spaces constitute a connective urban fabric that produces and reinforces internal and external connections.

激活开放和剩余空间69-70场地的特点是大量剩余和未界定的开放空间主导的地面停车。6970通过将这些剩余的区域改造成一个活跃的公共空间网络来刺激这个网站，我们称之为文化走廊。优化区域内现有的停车场使地面停车场最小化，停车场的正面通过引入绿色墙壁、媒体屏幕、艺术墙和攀岩墙而转化为活跃的表面。此外，每个街区都有一个主要的公共广场。

Activation of Open and Residual Spaces The 69-70 site features a large number of residual and undefined open spaces dominated by surface parking. 6970+stimulates the site by transforming these left-over areas into an active network of public spaces, which we call the cultural corridor. Optimizing the existing parking garages within the area minimizes surface parking, and the facades of parking garages are transformed into active surfaces by introducing green walls, media screens, art walls, and rock climbing walls. In addition,a main public plaza is introduced in each block.

摄政广场(部分灵感来自于UPAC建筑群的当前计划以及将摄政街改造成零售走廊的目标)被规划为一个开放的文化空间。摄政广场可以作为电影放映的活动空间(利用摄政街停车场的西面墙)、夏季的户外音乐会和冬天的溜冰。主广场是从未来大楼后面的100多个角落和主要街道上雕刻出来的，反映了该地区的文化规划。并为小型聚会、周末市场或只是一个工作日吃午饭的好地方创造了一个街区中间的开放空间。

The Regent Plaza (inspired in part by the current plans for the UPAC complex and the goal of transforming Regent St. into a retail corridor) is programmed as an open cultural space. Reflecting the cultural programming around the area, Regent Plaza can be used as an event space for film screenings (by utilizing the western wall of the parking garage on Regent St), outdoor concerts in the summer, and ice skating in winter.The Main Plaza is carved out of the back of the future building expected at the corner of 100 and Main streets, and creates a mid-block open space for small gatherings, weekend markets, or just a nice place to have lunch on a workday.

此外，一系列中街区通道作为半开放和季节性的空间，可以通过各种文化活动，如艺术展览，演示和其他公共集会规划。虽然他们的主要任务是流通，这些通道被认为是口袋，也可以编程。

In addition, a series of mid-block passageways are introduced as semi-open and seasonal spaces, which can be programmed through a variety of cultural activities such as art shows, presentations, and other public gatherings. While their main task is circulation, these passages are imagined as pockets that can also be programmed.

扩大使用范围在设计城市开放空间时必须考虑到SLC的气候条件。因此，为69-70网站设想的公共领域利用各种取暖和冷却策略来促进全年的室外规划。暖气是通过地面蒸汽阀提供的，这些蒸汽阀从干涸的水和融化的雪中产生蒸汽，以温暖较小的城市口袋，比如冬季的主广场，而薄雾柱在夏季的摄政广场会产生一种好玩的冷却效果。

Extension of Use It is important to take into consideration the climatic conditions of SLC when designing open spaces in the city. Hence, the public realm envisioned for the 69-70 site makes use of various heating and cooling strategies to facilitate outdoor programming throughout the year. Heating is provided through in-ground steam valves that generate steam from the run-off water and melting snow to warm up smaller urban pockets, such as Main Plaza in the winter months, while mist poles create a playful cooling effect in Regent Plaza in the summer.

实际上，这些微气候在季节上扩大了公共空间的使用范围。考虑到69-70站点的性质，以及该地区的文化、娱乐和餐饮活动，实施一项夜间激活站点的策略是非常重要的。在6970，这是通过一个照明策略，创造了一套活泼的流通空间，以及引导行人交通到现场的特定位置通过地面照明技术。

In effect, these microclimates extend the use of public spaces seasonally. Given the nature of the 69-70 site, and the cultural, entertainment, and dining oriented activities of the area, it is important to implement a strategy for the night-time activation of the site. In 6970+ this is done through a lighting strategy that creates a set of lively circulation spaces, as well as guiding the pedestrian traffic to specific locations of the site through in-ground lighting techniques.

上面提到的三种主要策略-主动曲面是通过一个主动曲面来实现的。活动面被想象为全年便利各种时间活动和事件的容器，其定义是空间的灵活性和操作的多样性。作为一个概念，活动表面被想象为一个像素化的表面，在这个表面中每个像素都是可编程的，并对局部条件作出响应，无论是气候、编程还是交互。像素很容易互换，并为组织站点及其各种设计元素创建了一个动态和灵活的结构。像素之间的相互作用产生了一个整体，它不仅响应特定的局部条件，而且响应更大的环境问题，如选址和生态敏感性，其大小大于其各部分的总和。

The Active Surface The three main strategies mentioned above are implemented through an Active Surface. Imagined as a container that facilitates a variety of temporal activities and events throughout the year, the Active Surface is defined by its spatial flexibility and operational diversity.As a concept, the Active Surface is imagined as a pixelated surface in which each pixel is programmable and responds to a local condition, be it climatic, programmatic or interactive. Pixels are easily interchangeable and create a dynamic and flexible structure for (re)organizing the site and its various design elements. The interaction among pixels generates a whole, which is greater than the sum of its parts by responding not only to specific local conditions but also to larger contextual issues of place making and ecological sensitivity.

实际上，每个像素的属性都是通过引入一组变量来定义的。这些变量包括材料特性(硬面或植被)以及操作和几何特性。因此，像素化从一种平面状态转变为三维形式，融合了各种城市设备，其中一些具有单一用途，如座椅和照明，还有一些具有更复杂的操作能力，如结构支撑或微气候生成。

In practice, the property of each pixel has been defined by introducing a set of variables. These variables include material properties (hard surface or vegetation) as well as operational and geometrical properties. The pixelation, therefore, transforms from a flat condition to three-dimensional form to incorporate a variety of urban equipments, some with singular uses, such as seating and lighting, and some with more complex operational capacities, such as structural support or micro-climate generation.

物质战略、犹他州和SLC的工业历史及其与采矿和采石场的关系通过6970的重要性反映出来。在6970的设计中使用的材料可以从犹他州的当地来源。活性表面的彩色铺路石(石灰石、砂岩和各种不同颜色的花岗岩)是在犹他州境内开采的，而各种城市设备的Corten包层将来自犹他州的铁矿，并在该州制造。此外，通过在城市设备设计中整合各种信息和通信技术，为这一重要性增加了一个新的数字层。

Material Strategy The industrial history of Utah and SLC and their relationship to mining and stone quarries is reflected through the materiality of 6970+. The materials used in the design of 6970+ can be sourced locally from within Utah. The multicolored paving stones of the Active Surface (Limestone, Sandstone and Granite of various shades) are quarried within Utah, while the Corten cladding of the various urban equipment will be sourced from the iron mines of Utah and manufactured within the state. In addition, a new digital layer is added to this materiality through the integration of various information and communication technologies in the design of the urban equipment.

通过这个数字平台提供的信息将传达69-70网站的事件和发生，并将在SLC的创意公司的帮助下制作。再加上可再生能源的产生、再利用和再利用，再加上从现场收集的径流水，这种虚拟物质性为6970的物质组成增加了一层新的智能层。从本质上说，6970的实质是充满了SLC的历史轨迹和它作为犹他州和世界级城市的创作核心的未来。

The information provided through this digital platform will communicate the events and happenings of the 69-70 site, and will be produced with the help of SLC's creative firms. Coupled with renewable energy generation and reuse and recycling strategies for the runoff water collected from the site, this virtual materiality adds a new layer of intelligence to the material composition of 6970+. In essence, the materiality of 6970+ is imbued with the historical trajectory of SLC and its future as the creative core of Utah and a world-class city.
