南京生态科技岛新纬壹科技园坐落于长江之中，距离市中心仅6.5公里，与新的中央商务区隔桥相望，力求助力南京的经济发展和所在地区未来的可持续发展事业。新纬壹科技园定位于打造南京市的高科技创新实践中心，以及市民与游客的生态休闲目的地，提供的一系列混合用途空间包括服务于科研孵化器和环保公司的办公建筑，以及一座文化设施和一条公共步道。
人尺度的空间为本地居民和访客带来了热情友好的体验。展馆处在园区的门户位置，屋顶轮廓线极富戏剧感，是访客自市区抵达科技岛之时对这座园区留下的第一印象。屋顶上的八个峰形尖角象征着临近的钟山和石山，每个峰尖均设有圆形开口或“导光口”，用于将自然采光引入大楼面内部。导光口的概念在八栋五角形办公科研楼的设计中得到了放大，这个建筑群的共有特色是设有大型内部庭院和景观屋顶。
这些科研楼的规模覆盖了大中小三个尺度，建筑形态深受该地区传统中国建筑的启发，屋檐高低错落，或降回地面，或扶摇而起——漂浮于天地之间。此外，周围连绵起伏的景观用来容纳咖啡厅和零售商业等空间，其有机形态是基于树木枝蔓的天然构造。
此项目触及到了有关中国可持续性与设计实践的一大关键话题，在中国持续飞速发展的情况下，设计普遍会关注于市政公共设施，因而也会涉及到更多的环境影响。项目的绿色特征有很多，目的是优化场地融合、日照采集、自然材料应用、水资源回收与过滤，以期达到节能减排的最终目的。
具有节能作用的建筑屋顶
展馆的双层屋顶可显著减少多余能耗，伸长的、悬挑屋檐具有被动遮阳作用——并能通过八个屋顶峰尖将自然采光带入到建筑室内深处。在环保顾问的协助下，项目团队开展了大量的日照研究工作，以便优化建筑形态，最大限度地获得建筑自然采光。展馆还依赖于地源热泵系统。通过这些节能措施的综合应用，建筑能耗与类似传统建筑相比减少到30%以上。
独特的办公场所
办公科研建筑——其中包括为研发机构设置的工作环境——通过一系列设计策略实现了持续制冷。建筑从地面层被抬高了一至两层，透过自然通风提升了被动制冷能力。另外，每栋建筑的五角形态促成了较窄的楼板布局，从而进一步优化了自然通风，并为室内引入了自然采光。
零径流水
办公科研楼及展馆均设有屋顶花园及露台，用于消除径流水，为本地野生动植物提供庇护场所，并为办公群体及展览观众带来生机勃勃的绿洲，供人们放松心情，并能欣赏到科技岛及南京市区的开阔视野。项目运用节水策略——诸如雨水收集等——帮助减少用水量，使灌溉用水量与传统系统相比减少了50%。此外，地面层的原生植被规模覆盖景观面积的30%以上，有助于控制径流水和减少土地流失，本土树种及灌木的应用也为展馆观众、办公人群及访客提供了引人注目的入口。此项目正在争取获得中国绿色三星等级认证。
Located in the Yangtze River, just 6.5 kilometers from the city’s downtown area and across the bridge from the new central business district, the Nanjing Eco Hi-Tech Island’s Xin Wei Yi Technology Park helps drives Nanjing’s economic advancement and the future of the area’s sustainable development. Positioned as Nanjing’s center for the practice of high-tech innovation, and an ecological destination and resource for citizens and tourists, the Xin Wei Yi Technology Park offers a range of mixed-use spaces, including office buildings that serve as incubators for technology and environmental companies, as well as a cultural venue and a public promenade.
Human-scale spaces offer a welcoming experience for locals and visitors alike. The Exhibition Hall, with its dramatic roofline, is the first impression of the campus as visitors approach the island from downtown. The eight peaks on the roof symbolize the neighboring Zhong and Stone Mountains, and each peak has an oculus or “light cannon” that drives natural light into the large floors. The concept of the light cannons are magnified in the design of the eight, pentagon-shaped Office Research Buildings, which feature large interior courtyards and landscaped roofs. Scaled from small to medium to large, the research building forms were inspired by ancient Chinese architecture in the region, where prominent roofs anchor buildings low to the ground and appear to float above — hovering at the horizon between earth and sky. In addition, the surrounding undulating landscape houses spaces for coffee shops and retail, and its organic form was based off of the branched structure of a tree.
The project touches on a critical conversation about sustainability and design practice in China, where development continues at lightning-fast speed and design has typically focused on utility and cost more than environmental impact. Multiple green features prioritize site integration, daylight harvesting, natural materials, water reclamation and filtration to help combat China’s carbon emissions.
Roofs that save energy
A dual-layer roof on the Exhibition Hall significantly reduces excess energy and long, cantilevered eaves provide passive shading — while the eight roof peaks bring daylight deep into the building. Numerous light studies, aided by an environment consultant, helped optimize their shape to maximize daylight. The hall also relies on a geothermal heat pump system. As a result, energy use is more than 30% lower than comparable conventional buildings.
Unique workplaces
The Office Research Buildings — which include work environments for research and development organizations — stay cool via a series of design strategies. They are lifted off the ground by one or two stories to increase passive cooling via natural ventilation. Furthermore, each building’s pentagonal shape creates narrower floors that further optimize natural ventilation and bring daylight inside. Additional features reduce energy use and excess heat, such as strategically placed vertical fins, which maximize passive cooling while maintaining clear, open views. The fins also showcase a playful abstracted interpretation of the buildings’ floorplan.
Zero water runoff
Rooftop gardens and terraces on both the Office Research Buildings and the Exhibition Hall eliminate water runoff, provide refuge for local wildlife and give office workers and exhibit visitors an invigorating oasis to refresh and take in the expansive views of the island and downtown Nanjing. Water saving strategies — such as rainwater harvesting — help reduce water use for irrigation by up to 50% compared to traditional systems. In addition, ground level native plantings cover more than 30% of the landscape to help control water runoff and reduce erosion, with local trees and shrubs providing a dramatic entry for exhibition attendees, office workers and visitors to the area. This project is now tracking China Green 3 Star.
