70 Rainey空中花圃入围 2021 WLA 大奖
70 Rainey Sky Garden was shortlisted in the 2021 WLA Awards
The Sky Garden, located in Austin, sets a precedent for growing up rather than out, and creates a deliberate connection to the surrounding landscape through careful plant selection. Recreating the Texas Hill Country landscape and utilizing nature as a healer, the Sky Garden creates protective microclimates 100 feet in the Texas sky.
The Sky Garden is dominated by plants and creates a scaled-down and elevated version of the region’s landscapes. Though famous for its limestone and granite, there is much to be said about the Hill Country’s utilitarian vegetation. Practicality was a defining characteristic in the design approach. Echinacea, Salvias, and Asclepias feed pollinator insects. endure extreme temperatures and Huisache trees shade guests. The Sky Garden also responds to its immediate surroundings. Heeding the building’s architectural cues, the design team curated a plant palette that blends building and nature.
为了让空中花圃免受德克萨斯州气候的影响，设计团队采纳了遍及的法子。首先通过风洞测试数据，记录不适宜植栽的位置。经心的植物搭配可以避风并晋升舒适度。葡萄藤交织爬上雕栏，提供四季的防护。从街道往上看，这些藤蔓是立于东面和南面的植物屏风的一部门。内地的金合欢为空中花圃小气候的乐成营造中发挥了浸染。金合欢位于东南角，遮蔽夏季高出 6 小时的日晒，它们配合形成了一个大型树冠，低落花圃温度的同时答允阳光透过。这些设计计策为享受空中花圃缔造了抱负的情况。
Extensive measures were taken to ensure the Sky Garden was protected from Texas’s elements. Wind tunnel test data revealed locations where turbulence would create uninhabitable conditions. Deliberate planting interventions were invoked to curb winds and create comfortability. Crossvines climb the railings, providing year-round protection. From the street, these vines are part of the screen plant composition that shields the east and south faces. Native Huisache trees also play a role in the success of the Sky Garden’s microclimates. Located in the southeastern corner, which receives over six hours of sunlight during summer, these trees create another canopy that lowers temperatures on the deck but allow sunlight to filter through. These design decisions create an ideal environment for enjoying the Sky Garden.
这座9,300 平方英尺的露天阳台高出 43% 是由花圃和水池构成的。种植区减缓并接收雨水，淘汰流入都市雨洪系统和鸟湖的雨水径流。空中花圃的其他情况效益还包罗充分氧气和增加授粉。
Of the 9,300 square feet of rooftop exposed to the sky, over 43% is comprised of gardens and a pool. Rainwater is slowed and absorbed by the planting areas, which help reduce runoff to the city’s storm system and Lady Bird Lake. Other environmental benefits that can be attributed to the Sky Garden include reoxygenation and increased pollination.
