The 206-meter, 49 story Quay Quarter Tower (QQT) is a once-in-a-generation project. Located on the edge of Sydney’s bustling Circular Quay, the tower “upcycles” the existing AMP Centre tower. Built only in 1976, the original AMP Centre was reaching the end of its usable lifespan, but rather than simply tear it down and start over, the project team set out to reach an ambitious goal: to reuse as much of the existing building and set a lofty new standard for what is possible for adaptive reuse in architecture.

206 米、49 层的 Quay Quarter 塔 (QQT) 是千载难逢的项目。该塔位于悉尼繁华的环形码头边缘，是对现有 AMP 中心塔的“升级改造”。最初的 AMP 中心建于 1976 年，其使用寿命即将结束，但项目团队并没有简单地将其拆除后重新建设，而是着手实现一个雄心勃勃的目标：尽可能多地重复使用现有建筑和设置一个关于在建筑中自适应重新利用的可能性的崇高的新标准。

Today, that goal has been achieved. QQT retains over 65% of the original structure (beams, columns, and slabs) and 95% of the original core, resulting in an embodied carbon saving of 12,000 tonnes (the equivalent of 35,000 flights between Sydney and Melbourne).

今天，这个目标已经实现。 QQT 保留了超过 65% 的原始结构（梁、柱和板）和 95% 的原始核心筒，从而实现了 12,000 吨的具体碳减排（相当于悉尼和墨尔本之间的 35,000 个航班）。

The World’s First Tower Transformation 世界上首个塔改造

Transformation is a sustainable initiative, and for Quay Quarter Tower, there are three levels of sustainability: Environmental, Social, and Urban. The First, environmental sustainability, focuses on two main features. The first is a facade with an external sunshade hood, which blocks 30% of the solar radiance, reducing mechanical loads and eliminating the need for internal blinds for thermal control, and the second form of environmental sustainability is to retain 2/3 of the existing structure.

改造是一项可持续的举措，对于 Quay Quarter Tower，可持续性分为三个级别：环境、社会和城市。首先，环境可持续性，侧重于两个主要特征。第一种是带有外部遮阳罩的外立面，可阻挡 30% 的太阳辐射，减少机械负荷并无需内部百叶窗进行热控制，第二种环境可持续性形式是保留 2/3 的现有结构体。

The former gives the building a strong identity and texture to the building envelope, while the second, less visible, it upcycles an older building asset, giving it new life and reinvigorating the surrounding precinct. This leverages the existing infrastructure of the building and urban environment to sustain a precinct and revitalize it, giving new life to a formerly tired precinct.

前者为建筑围护结构赋予了强烈的身份和质感，而第二个则不太显眼，它升级了旧建筑资产，赋予其新的生命并重振了周围的区域。这利用了建筑和城市环境的现有基础设施来维持和振兴一个区域，为以前疲乏的区域赋予新的生命。

Shaping Quay Quarter Tower 塑造 Quay Quarter 塔

Quay Quarter Tower is composed of five stacked and shifted volumes; the lower floors face the bustling Young Street and Harbour Bridge, and fan out eastwards as they climb to frame panoramic views onto the Royal Botanic Gardens and the Sydney Opera House.

Quay Quarter Tower 由五个堆叠和移动的体量组成；较低的楼层面向熙熙攘攘的青年街和海港大桥，向东呈扇形展开，可以欣赏到皇家植物园和悉尼歌剧院的全景。

Working within the solar envelope and other contextual constraints, the design adds approximately 45,000m2 of new construction, primarily on the north side of the building by grafting on new floorplates to the existing slabs. The new structure composed of concrete filled, steel tubes optimizes the structural grid span to increase views to the harbour. The façade’s external sunshade hoods, reduce the heat loads on the building so that internal blinds are not needed for thermal comfort. The façade design not only reduces energy loads, but also ensures that the views to the world recognized Sydney Harbour and its icons are always within view.

在太阳能围护结构和其他环境限制下，该设计增加了大约 45,000 平方米的新建筑，主要是在建筑物的北侧，通过将新楼板移植到现有楼板上。由混凝土填充钢管组成的新结构优化了结构网格跨度，以增加对海港的视野。立面的外部遮阳罩减少了建筑物的热负荷，因此不需要内部百叶窗来获得热舒适性。立面设计不仅减少了能源负荷，而且确保世界公认的悉尼港及其标志性景观始终在视野范围内。

The Vertical Village 垂直村落

Quay Quarter Tower was developed around a “vertical village” concept, designed from both the inside out and the outside in and with the user experience top of mind. By dividing the building into five separate volumes, the best of both worlds is achieved: an optimal balance between intimacy and connectivity.

Quay Quarter Tower 是围绕“垂直村落”概念开发的，从内到外和从外到内的设计都将用户体验放在首位。通过将建筑分成五个独立的体块，实现了两全其美：亲密感和连通性之间的最佳平衡。

Each of the tower’s five volumes are a hub unto themselves, floors threaded together by a spiral stair and arranged around stacked atria that bring daylight deep into the 2,000sqm floorplates. The visual transparency of the open atrium spaces allows for easy visual access to the surrounding areas, departments, and colleagues, thus promoting collaboration and interaction. As an additional benefit the rotated volumes help self-shade the northern façade from harsh afternoon sun, creating a passive sustainability feature.

塔楼的五个体量中的每一个体量都是一个中心，楼层由螺旋楼梯连接在一起，并围绕堆叠的中庭排列，将日光引入 2,000 平方米的楼板深处。开放式中庭空间的视觉透明度可以让人们轻松地看到周围区域、部门和同事，从而促进协作和互动。作为一个额外的好处，旋转的体积有助于在午后的严酷阳光下自我遮蔽北立面，创造一个被动的可持续性特征。

The outdoor area of each entrance, the roof-top terrace and terraces become interactional spaces - social micro-scale urban place elevated above ground that allows employees to meet, linger and interact. These types of semi-public communal areas afford frequent chance meetings, social interactions and a sense of community among the users.

每个入口的室外区域、屋顶露台和露台成为互动空间——高出地面的社交微尺度城市场所，让员工可以见面、逗留和互动。这些类型的半公共公共区域提供频繁的机会会议、社交互动和用户之间的社区感。
