气候宣言体育馆丨美国西雅图丨POPULOUS

在一开始，气候宣言体育馆（Climate Pledge Arena）是一项被许多人认为永远不会实现的大胆计划。当“翡翠之城”西雅图（Seattle）开始重新规划和重建这座最初为1962年的21世纪博览会（Century 21 Exposition，又称西雅图世界博览会）而建的历史性地标时，世界顶尖的体育和娱乐建筑公司POPULOUS（博普乐思）颠覆了传统的体育馆模式，创造了一座前所未有的里程碑式的体育馆。

Climate Pledge Arena is the result of a bold undertaking many believed would never materialize. When the City of Seattle set out to reimagine and redevelop the historic landmark originally built for the 1962 World’s Fair, Populous flipped the traditional arena model on its head to create a first-of-its-kind arena.

气候宣言体育馆是该地区最大的体育馆，也是在原有建筑屋顶下建造的全新场馆，它不仅振兴了历史地标，还为两支主场球队——北美冰球职业联盟西雅图海怪队（NHL’s Seattle Kraken）和美国女子职业篮球联盟西雅图风暴队（WNBA’s Seattle Storm）的球迷，以及演唱会和其他活动的粉丝带来了极致体验。不同的场地模式下，该体育馆可容纳1.71万人观看冰球比赛，或是1.83万人观看篮球比赛。美国互联网巨头亚马逊公司（Amazon）为其冠名合作伙伴，POPULOUS也因此调整了可持续设计方法，以满足“气候宣言”的要求——这是一项由亚马逊牵头的全球倡议，签署方须承诺在2040年前实现其所有业务的零碳排放。

Climate Pledge Arena is the region’s largest arena — an entirely new venue built under an existing roof — that revitalizes a historic landmark and cultivates the ultimate experience for fans of the NHL’s Seattle Kraken, WNBA’s Seattle Storm, concerts and other events. With Amazon as the arena’s naming rights partner, Populous transformed its sustainable design approach to meet The Climate Pledge, a global initiative that commits signatories to net zero carbon across their businesses by 2040.

2021年10月，气候宣言体育馆竣工并以一场慈善音乐会的形式正式向公众开放。2023年10月，气候宣言体育馆成为了世界上第一座获得国际未来生活研究所（IFLI）零碳认证（Zero Carbon Certification）的体育馆，也是迄今为止世界上获得IFIL零碳认证的最大建筑。IFLI是一家全球性非营利组织，采用严格的数据标准来测评碳中和。其在认证过程会审查连续12个月的性能数据，以确定建筑是否在日常运营中实现了净零碳排放和抵消了施工期间的碳排放。测评碳中和的过程基于IFLI制定的严格要求，其中包括场馆使用的能源须100％来自可再生能源渠道、利用零可燃燃料（zero combustible fuel）以及减少建筑结构中的总体隐含碳（overall embodied carbon）。

In October 2021, Climate Pledge Arena was completed and officially opened to the public with a charity concert. In October 2023, the arena has become the first arena in the world to achieve Zero Carbon Certification from the International Living Future Institute (IFLI), a global nonprofit that uses strict, data-based standards to determine carbon neutrality. The ILFI certification process reviews 12 consecutive months of performance data to decide if a structure achieves net zero carbon emissions in its day-to-day operations and has offset the emissions from its construction period. The process to determine carbon neutrality is based on rigorous requirements set by the IFLI, which include sourcing 100% of the energy used in the arena from renewable energy avenues, utilizing zero combustible fuel types and reducing overall embodied carbon in the structure.

气候宣言体育馆完全就是一座公园里的体育馆，这在类似的大型公共集会场所中都是很罕见的，更不用说那些位于市区的体育场馆了。该体育馆在尊重其设计初衷的同时，还激活并加强了以行人为中心的城市规划，与临近的娱乐综合区西雅图中心（Seattle Center）相连接，并成为周围社区的开放式公共空间。

Climate Pledge Arena is quite literally an arena in a park, something unheard of for a large public assembly venue, let alone one set in an urban neighborhood. The arena honors its original design intent while activating and enhancing a pedestrian-focused plan, giving the site back to the Seattle Center campus and serving as open public space for the neighboring community.

“POPULOUS设计了世界上最美丽的体育馆，海怪队为能把它当作自己的主场球场而感到自豪。我们很高兴球迷们能在比赛日走进气候宣言体育馆，在为自己喜爱的球员加油的同时，被它的美丽所震撼，并获得一流的观赛体验。” ——西雅图海怪队首席执行官托德·雷韦克（Tod Leiweke） “Populous has designed the most beautiful arena in the world, and the Kraken are proud to call it home. We’re excited for fans to walk into Climate Pledge Arena on game day and be blown away by its beauty and have a first-class experience while cheering on their favorite players.” —TOD LEIWEKE, CEO of the Seattle Kraken

该场馆的建造工程包括将重达4400万磅的屋顶吊起并悬停在场地上方，同时还需要移走地下68万立方码（yd³）的泥土，从而使原场馆的面积扩大了近一倍，并创造出了360度的步行通道。美丽的玻璃幕墙也得到了修复，这使得气候宣言体育馆成为北美第一座可以完全环绕场馆行走的场馆，同时还能看到体育馆内部的情况。

The new construction required the 44-million-pound roof to be lifted and suspended above the site while another 680,000 cubic yards of soil were removed underneath to nearly double the size of the former venue and create 360-degree pedestrian access. The beautiful curtain walls of glass were also restored, making Climate Pledge Arena the first in North America where someone can walk entirely around the facility while never losing sight of what’s inside.

这座新体育馆在其他视觉方面也突破了界限。与其他场馆的视频显示设备不同，气候宣言体育馆拥有世界上第一个悬挂式双记分牌。这一标志性设计的背后是对冰球和篮球比赛时冰上和球场上的动作、观众和运动员的视线以及演出和音乐会场地灵活转换的全面分析。观众席的布置增强了球迷的体验感，并将观众与对峙、罚球和进球等比赛动作联系在一起。体育馆内共有59间豪华包厢，其中19间是位于观众席下方的通道俱乐部包厢，当球员从更衣室走向冰场或球场时，坐在那里的球迷们得以近距离观看这一切。

The new venue pushes the boundaries on other visual aspects as well. Unlike other arena video displays, Climate Pledge Arena boasts the world’s first dual suspended professional arena scoreboards. Behind this signature design lies a thorough analysis of on-ice and on-court action for hockey and basketball, spectator and athlete sightlines, and flexibility for shows and concerts. This placement bolsters the fan experience and connects the audience to the action of faceoffs, free throws and inbounding plays. There are 59 luxury suites, 19 of which are tunnel club suites situated under the seating bowl, giving fans a close-up view of the players as they walk from the locker room to the ice or court.

该体育馆的设计还采用了许多可持续的做法和运营方式。原先的屋顶并未被拆除，而是在翻新后得到了再利用，显著减少了建设过程中的碳排放。馆内设施完全采用可再生能源驱动，包括通过中庭屋顶收集的太阳能。场馆设计与轨道交通紧密相连，并为电动汽车充电站和自行车停放处提供了空间。POPULOUS做出的设计还支持零废弃物倡议和节水系统，能从屋顶收集雨水后使用不产生温室气体的制冷剂将其转化为NHL最环保的冰面。馆内有一面200英尺长的“生长”墙，上面悬挂着绿色植物，亚马逊的环保愿景经由POPULOUS之手变为了现实。馆内还有一面LED墙，详细介绍了开发零碳场馆的重要性。

The arena is also designed to employ numerous sustainable practices and operations. The original roof was not dismantled, but reused in the renovation, significantly reducing footprint of the construction process. The facility is powered solely on renewable energy sources, including on-site solar energy on the atrium roof. The site design builds strong connections with the monorail and provides space for electric vehicle charging stations and bike valet services. The design also supports water conservation systems — such as harvesting rainwater from the roof to turn it into the greenest ice in the NHL — and zero waste initiatives. The venue is home to a 200-foot living wall with greenery hanging overhead, an Amazon vision that Populous brought to life. The space also features an LED wall that details the importance of developing a zero carbon arena.

除了屋顶太阳能电池板产生的电力外，气候宣言体育馆和亚马逊还购买并兑换了超过10万兆瓦时的可再生能源证书（RECs），其中一些来自普吉特海湾能源公司的下蛇河风力发电场（Puget Sound Energy’s Lower Snake River Wind Farm）。该体育馆还承诺成为西雅图城市之光电力公司（Seattle City Light）“可再生+”（Renewable Plus） 计划的首批商业客户之一——该计划旨在为气候宣言体育馆提供可再生能源服务，预计将于2025年投入使用。

In addition to the electricity generated by the rooftop solar panels, Climate Pledge Arena and Amazon purchased and retired more than 100,000 megawatt hours of Renewable Energy Certificates (RECs), some of which are from Puget Sound Energy’s Lower Snake River wind farm. The arena has also pledged to be one of the first commercial customers for Seattle City Light’s Renewable Plus program, a program structured to provide renewable energy for the arena, which is projected to be available in 2025.

该体育馆在实现自身的碳中和行动之外，还在面向客户的运营中采用了可持续发展的做法，如消除一次性塑料制品，并为每位购买比赛或活动门票的观众提供免费公交服务。

The arena goes beyond its actions to achieve carbon neutrality and employs sustainable practices in its client-facing operations, such as eliminating single-use plastics and offering free public transit with every game or event ticket.
